While current guidelines emphasize risk stratification, the integration of artificial intelligence (AI)-driven models, including LightGBM, random forest, and logistic regression, for personalized treatment recommendations has not been extensively explored. This study develops and validates an AI-driven framework that leverages UAE-specific and global datasets to refine DAPT duration and optimize post-PCI outcomes. Methods: Patient data from the Bayanat Data Portal (UAE) and the global MIMIC-IV PhysioNet database were analyzed. Baseline characteristics, ischemic and bleeding events, and long-term clinical outcomes were assessed over a 37-month follow-up period. Among the tested AI models, LightGBM demonstrated the highest predictive accuracy compared to conventional DAPT risk scores. Kaplan-Meier survival analysis, receiver operating characteristic (ROC) curves, and feature importance analysis were used to compare risk-adjusted DAPT strategies. Cost-effectiveness was evaluated based on healthcare resource utilization and quality-adjusted life years (QALYs). Results: Among 5,000 patients, factors such as obesity, prior myocardial infarction (MI), and genetic predispositions significantly influenced DAPT-related outcomes. LightGBM achieved an area under the curve (AUC) of 0.89, surpassing conventional risk scores (AUC: 0.75, p<0.001). Kaplan-Meier curves revealed a significant survival advantage for AI-personalized DAPT (log-rank p<0.01). Shorter DAPT durations increased ischemic risk in high-risk patients, while longer therapy heightened bleeding complications. AI-driven risk stratification reduced unnecessary medication exposure,translating into improved cost-effectiveness and optimized treatment outcomes. Conclusion: AI-based DAPT personalization significantly enhances risk prediction and clinical decision-making, outperforming traditional models. Integrating UAE-specific data ensures regional applicability, reinforcing the need for precision-driven post-PCI management.

Future Research Directions: This study paves the way for prospective clinical trials validating AI-based risk stratification in large, diverse populations. Introduction The effective management of acute coronary syndromes (ACS) and the refinement of dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) remain major clinical challenges. Despite advances in drug-eluting stents (DES) and personalized risk scores, achieving an optimal balance balance between reducing ischemic events and minimizing bleeding complications is still complex. This is particularly evident in heterogeneous populations such as those in the United Arab Emirates (UAE), where diverse genetic, metabolic, and lifestyle factors influence cardiovascular risk. [1] [2] Currently, conventional DAPT duration strategies rely on fixed-duration protocols or risk scores like the PRECISE-DAPT and DAPT scores. However, these static models lack real-time adaptability to patient-specific clinical characteristics. Recent artificial intelligence (AI)-driven approaches, including LightGBM, random forest, and logistic regression, have demonstrated superior accuracy in predicting ischemic and bleeding risks compared to traditional scoring models. [3][4] Recent advancements in AI-driven risk prediction models, including LightGBM, random forest, and logistic regression, present transformative possibilities in cardiology. These models have demonstrated superior accuracy in predicting ischemic and bleeding complications compared to traditional risk scores. [5] By analyzing intricate datasets—including clinical, procedural, and genetic information—AI models offer highly accurate predictions of ischemic and bleeding risks. The use of explainable AI (XAI) further ensures model interpretability, enhancing clinician trust in AI-driven recommendations. [6] UAE-specific cardiovascular risk factors, including high diabetes prevalence (18.3%), genetic polymorphisms (e.g., CYP2C19 variants), and regionally distinct care practices, necessitate localized risk stratification strategies. [7] Existing global DAPT guidelines often fail to account for ethnic and geographic variability, leading to suboptimal patient outcomes. This study hypothesizes that AI-driven DAPT optimization, integrating UAE-specific and global datasets, will enhance post-PCI outcomes by refining personalized, data-driven therapy recommendations. [8] This study hypothesizes that AI-driven DAPT personalization, leveraging UAE-specific and global datasets, will enhance post-PCI outcomes by providing individualized, dynamic therapy recommendations. This framework aims to incorporate structured and unstructured data sources, including electronic health records (EHR), patient demographics, laboratory values, and procedural characteristics, to optimize DAPT duration and improve clinical outcomes. [9][10] Moreover, by comparing AI-driven strategies with conventional risk scores, this study aims to quantify the incremental benefit of machine learning-based approaches in balancing ischemic and bleeding risks while evaluating cost-effectiveness in real-world clinical settings. [11–16] This research aims to integrate patient-specific predictors (i.e., laboratory parameters, comorbidities), procedural characteristics (i.e. lesion complexity and types), and post-PCI clinical data seeking to balance ischemic and bleeding risk predictions on providing recommended optimized outcome. We evaluated the role of UAE-specific genetic predispositions, regional changes, risk factors and life style variations in cardiovascular practice influencing post-PCI conclusion, supporting precision medicine strategy. Also, our study highlighted the patient safety in UAE on enhancing AI potential and healthcare efficiency assessing both the economic and clinical challenges impacting the AI-driven DAPT personalization comparing the ischemic complications and bleeding events. Methodology 2.1 Development of the AI-Driven Framework Data Sources and Ethical Consideration This research makes use of publicly accessible datasets that were available before the study commenced. Specifically, two primary datasets were utilized: Bayanat Data Portal (data.bayanat.ae) : The dataset titled "Prevalence of Obesity in the UAE" was retrieved from this official open data platform, which provides publicly available and government-verified health statistics. This dataset adheres to UAE regulatory requirements for sharing public data and is anonymized for privacy compliance. MIMIC-IV (Medical Information Mart for Intensive Care, v2.0) : Hosted on PhysioNet, this dataset comprises de-identified electronic health records from ICU patients. It complies with HIPAA regulations and institutional review board (IRB) guidelines. Access to MIMIC-IV requires researchers to complete mandatory ethics training and sign the data use agreement (DUA). More information is available at https://physionet.org/content/mimiciv/2.0/. This study did not involve any personally identifiable information (PII). All data handling processes adhered to international ethical principles, including those outlined in the Declaration of Helsinki. As both datasets are anonymized and publicly accessible, their use did not require further IRB approval. Moreover, this study analyzed post-PCI patients receiving dual antiplatelet therapy (DAPT) using electronic health records (EHRs), procedural reports, and clinical registries. Key variables included: Demographics: Age, gender, BMI, smoking status Comorbidities: Diabetes, hypertension, atrial fibrillation Laboratory markers: Cholesterol, hemoglobin, genetic variants (CYP2C19) Procedural details: Stent type, lesion complexity Regional risk factors: UAE-specific genetic and lifestyle influences Figures 2 and 6 highlight risk stratification and AI-based dynamic treatment recommendations for optimizing real-time DAPT adjustments. Feature Engineering To enhance predictive accuracy, feature selection incorporated Recursive Feature Elimination (RFE) and SHapley Additive exPlanations (SHAP). High collinearity variables were excluded (variance inflation factor > 5). Machine learning models included: Random forests & gradient boosting (LightGBM): Identified key predictors of ischemic and bleeding risk. Deep neural networks (DNNs): Captured high-dimensional feature interactions. Explainable AI (XAI) techniques (SHAP, LIME): Ensured model interpretability for clinical use. AI Model Selection and Transparency To maintain clinical relevance and reliability, the AI-driven framework for personalizing dual antiplatelet therapy (DAPT) duration incorporates well-established practices for model interpretability: Feature Selection & Clarity : The framework utilizes SHAP (Shapley Additive Explanations) values to assess the influence of key clinical factors—such as previous ischemic events, platelet reactivity, and bleeding risk—on DAPT duration recommendations. This ensures transparency and aligns with the principles of explainable AI (XAI) in healthcare. Model Validation : The predictive model was developed using the MIMIC-IV dataset and externally validated against the Bayanat dataset to evaluate its applicability within the UAE population. Robustness was assessed through cross-validation techniques and performance metrics, including AUC-ROC and calibration plots. Clinical Interpretability & Decision Support : AI-generated recommendations serve as decision-support tools rather than standalone clinical directives. Outputs are paired with conventional risk scores—such as PRECISE-DAPT—to enhance interpretability and ensure compliance with guideline-based therapeutic approaches. By implementing these interpretability measures, the study maintains scientific rigor, regulatory compliance, and clinical applicability, mitigating concerns regarding AI opacity in medical decision-making. In addition, machine learning (ML) and deep learning (DL) algorithms were employed to analyze the multidimensional dataset. Random forests and gradient boosting machines (GBM) were used for their ability to handle complex, heterogeneous data and identify critical predictors (Figure 2). Deep neural networks (DNNs) were deployed to explore high-dimensional interactions. Transparency was ensured using explainable AI (XAI) methods, such as SHapley Additive exPlanations (SHAP) and Local Interpretable Model-agnostic Explanations (LIME). Model performance was assessed with ROC curves (Figure 1B) to ensure accuracy in risk prediction. Handling Missing Data 15% missingness: Multiple imputation methods or feature exclusion Hyperparameter tuning: Used Bayesian optimization and grid search for optimizing AI model performance. 2.2 Evaluation of UAE-Specific Risk Factors Risk Factor Identification Genetic & Lifestyle Influences: AI-based stratification assessed CYP2C19 polymorphisms, obesity, and metabolic factors (Figure 6B). Statistical Validation: Multivariate regression & SHAP analysis identified key predictors. 2.3 Clinical and Economic Impact Assessment Study Design: Propensity-score matching compared AI-guided DAPT vs. fixed-duration therapy. Outcome Measures: Kaplan-Meier curves (Figure 1A) evaluated ischemic/bleeding events . Cost-Effectiveness: Measured via QALYs & Incremental Cost-Effectiveness Ratios (ICERs). Bias & Generalizability Consideration External validation was conducted using non-UAE datasets to assess generalizability, ensuring AI-driven DAPT recommendations remain effective across global populations. Validation The model was validated through cross-validation and external datasets from UAE healthcare centers. Cross-validation optimized AI models, including gradient boosting and neural networks, while external validation tested the model on independent cohorts ensuring the robustness beyond its training population . [9] [17] Kaplan-Meier survival analysis (Figure 1A) evaluated ischemic and bleeding risk stratification. Calibration plots (Figure 3) confirmed predictive alignment with observed outcomes. Regional factors, including genetics and lifestyle, further refined the model for both local and global applications. [4] [5] Non-UAE nationals datasets were used for external validation to evaluate generalizability, ensuring the AI model retains its predictive accuracy across various populations. [10][14][15] 2.3 Assessment of Clinical and Economic Impact Study Design A propensity score-matched analysis compared AI-guided DAPT personalization with fixed-duration care. Time-to-event analysis (Figure 4 Panel A) assessed differences in ischemic and bleeding events, validating AI’s effectiveness. Outcome Measures Primary outcomes included major adverse cardiac events (MACE) such as myocardial infarction and bleeding complications (e.g., BARC criteria), visualized via Kaplan-Meier curves (Figure 1A). Secondary outcomes evaluated healthcare costs, patient adherence (Figure 7 Panel B), and quality-adjusted life years (QALYs). Clinical benefit analysis (Figure 7 Panel A) and hospitalization rates were also measured. Cost-Effectiveness Analysis Cost-effectiveness, measured by QALYs and ICERs, was improved through AI-driven risk stratification, which optimized DAPT duration and minimized unnecessary prolonged therapy risks. Dynamic prediction (Figure 6) reduced costs and ischemic and bleeding complications. Bias and Generalizability Consideration To enhance its applicability, the model underwent external validation using datasets beyond the UAE, confirming consistent performance. Nonetheless, biases may emerge from variations in healthcare access, genetic diversity, and lifestyle factors across regions. To mitigate this, diverse cohorts were included, and model parameters were adjusted. Further research is necessary to assess the effectiveness of AI-driven DAPT personalization across different ethnicities and clinical environments. Result Baseline Characteristics of Ischemic and Bleeding Events The baseline characteristics of patients, as seen in Table 1 categorized by the occurrence of ischemic events over 37 months, revealed significant distinctions. Obesity, diabetes, and prior myocardial infarction (MI) were more prevalent among those with ischemic events (p < 0.05). Metabolic syndrome was also strongly linked to adverse outcomes, reinforcing existing evidence on its impact in acute coronary syndromes. [9] Patients with ischemic events were older (mean age 67.4 ± 10.5 years, p < 0.001) and had higher BMI values (29.3 ± 5.1 vs. 27.6 ± 4.8 kg/m², p = 0.002). Male patients were predominant in the ischemic group (65.8%), suggesting sex-related risk factors (p = 0.004). Cardiovascular risk factors were notably higher in the ischemic cohort, including prior ischemic heart disease (52.7% vs. 38.2%, p < 0.001), MI history (34.9% vs. 20.3%, p < 0.001), and hypertension (78.6% vs. 65.1%, p = 0.001). The prevalence of atrial fibrillation (12.4% vs. 6.8%, p = 0.006) and current smoking (31.2% vs. 21.6%, p = 0.003) was also significantly greater. Interestingly, Ticagrelor (p < 0.001) and anticoagulant use (p = 0.005) were more frequent in the non-ischemic group, reflecting strategies to mitigate ischemic risks. Prolonged anticoagulation therapy, associated with increased bleeding risks, was prevalent in patients who experienced bleeding events (p < 0.01). [3] Table 1: Baseline Characteristics of Cases With and Without Ischemic Events (0–37 Months Cohort Dataset Similarly, the baseline characteristics of patients with bleeding events as seen in Table 2 highlighted significant differences. These patients were older (mean age 70.2 ± 9.6 years vs. 65.8 ± 10.1 years, p = 0.002) and often had prior bleeding episodes (19.8% vs. 8.4%, p < 0.001) or were on anticoagulants (36.5% vs. 18.1%, p = 0.004). Higher prevalence of anemia (23.6% vs. 11.7%, p < 0.001) and chronic kidney disease (21.5% vs. 13.2%, p = 0.002) was noted in this group. DAPT strategies such as Ticagrelor (p = 0.008) and corticosteroid use (p = 0.012) were linked to higher bleeding risks. These findings emphasize the critical need for dynamic, risk-adjusted therapy to balance ischemic protection and bleeding risk. Kaplan-Meier Survival Analysis Figure 1 displays Kaplan-Meier survival curves comparing ischemia-free survival between obese and non-obese groups, revealing a significant difference (log-rank p < 0.05) that aligns with evidence linking obesity to ischemic risk. [1] The survival curves also depict event-free probabilities over time for various DAPT strategies. The blue curve (ischemic events) decreases more gradually, reflecting extended survival probabilities, while the orange curve (bleeding events) declines faster, indicating a higher incidence of bleeding complications. The statistically significant finding (p < 0.05) underscores a crucial balance: extended DAPT durations lower ischemic risk but increase bleeding risk, a key consideration for optimizing DAPT through AI. Figure 1B supports this further with Receiver Operating Characteristic (ROC) curves assessing the AI model’s accuracy in predicting ischemic (blue) and bleeding (orange) risks. The model demonstrates strong performance (AUC > 0.80), outperforming the baseline random classifier. The false-positive rate (x-axis) and true-positive rate (y-axis) highlight a beneficial trade-off in classification accuracy. Results suggest that AI-driven DAPT models enhance survival by optimizing therapy duration based on risk levels. Sensitivity and Specificity Analysis: - The model achieved an AUROC of 0.82 for ischemic events, with 85.2% sensitivity and 78.6% specificity. - For bleeding events, the AUROC was 0.79, showing 80.1% sensitivity and 75.3% specificity. - These outcomes show the model's ability to identify high-risk patients while avoiding prolonged DAPT in low-risk cases. Figure 2 presents bleeding-free survival curves stratified by BMI, demonstrating that higher BMI correlates with elevated bleeding risks, consistent with prior research on obesity-related hemostatic issues. [6] [12] The Feature Importance Plot highlights the leading predictors for AI-driven DAPT management. Blue bars represent ischemic predictors, such as DAPT duration (score: 0.85) and ischemic heart disease history (score: 0.79), while orange bars reflect bleeding predictors like prior bleeding events (score: 0.83) and anticoagulant use (score: 0.76). Other factors, including hypertension (0.65, blue) and age (0.71, orange), underscore the complex interplay of risks. These findings affirm the alignment of AI-driven feature selection with clinical expertise, bolstering the development of a data-driven approach to tailoring DAPT duration. AI-Powered Risk Stratification and Predictive Performance Figure 3 showcases calibration plots for ischemic and bleeding predictions using Model 1 (blue) and Model 2 (orange). The x-axis represents predicted probabilities, while the y-axis denotes observed event rates. Model 1 aligns well with the reference diagonal, indicating accurate risk predictions, whereas Model 2 overestimates bleeding risks at higher probabilities. Figure 4A provides a time-to-event comparison of ischemic and bleeding outcomes with short (≤6 months) and long (>6 months) DAPT durations over 37 months: - The blue curve (ischemic events) shows a higher cumulative incidence with short DAPT, especially within 6–12 months, marking a critical ischemic risk period. - The orange curve (bleeding events) rises sharply with long-duration DAPT, notably beyond 12 months, confirming increased bleeding risks. Figure 4 presents the AI model’s calibration plot, validating its predictive accuracy for adverse cardiovascular events. [17] The forest plot highlights subgroup hazard ratios (HR), showing that extended DAPT greatly benefits patients with prior ischemic heart disease (HR: 2.1, p < 0.01) but increases bleeding risk for anticoagulant users (HR: 0.78, p = 0.03). Younger patients (HR: 0.95, p = 0.07) exhibit minimal changes in DAPT-related risk. These findings confirm that tailored DAPT strategies maximize ischemic risk reduction while minimizing bleeding risks, reinforcing the clinical value of AI-based decision-making. Time-to-Event Analysis Table 3 highlights the time-to-event analysis for ischemic and bleeding outcomes. Patients with shorter DAPT durations (12 months) was associated with greater bleeding risk (HR: 2.10, p = 0.01), consistent with current guidelines. [15] [18] Among AI models, the LightGBM model demonstrated the best performance, achieving AUROCs of 0.87 for ischemic events and 0.85 for bleeding, reflecting strong discriminatory power. Its sensitivity for ischemic event detection reached 83.5%, effectively identifying high-risk patients, while its specificity for bleeding events was 79.6%, reducing false positives in clinical decisions. Traditional logistic regression performed less effectively, with AUROCs of 0.73 (ischemia) and 0.70 (bleeding), illustrating its limitations for complex risk stratification. These findings underscore the superiority of advanced machine learning models like LightGBM and Neural Networks in enhancing AI-driven risk prediction for DAPT management. Feature Importance in AI-Driven Predictions Figure 5 outlines significant predictors in AI-driven DAPT customization based on SHAP values: - DAPT duration (score: 0.85) and prior ischemic heart disease (score: 0.79) were the top predictors for ischemic risk (blue bars). - Prior bleeding events (score: 0.83) and anticoagulant use (score: 0.76) were the leading predictors for bleeding risk (orange bars). - Hypertension (0.65) and age (0.71) influenced both ischemic and bleeding risks. Table 4 evaluates the AI model's performance against traditional risk scores. It outperformed PRECISE-DAPT and DAPT models, achieving improved specificity (87% vs. 72%). [16] The AI model's accuracy evolved across six time intervals (0–36 months), showing adaptability in risk tracking. At 6 months, ischemic risk prediction peaked with an F1 score of 0.84 and AUROC of 0.86, reflecting early post-PCI clustering. By 24 months, bleeding risk surpassed ischemic risk, highlighting the need for therapy adjustment. At 36 months, the AI-driven model demonstrated stabilized risk scores, validating long-term applicability. These findings underscore the importance of time-sensitive recalibration in AI-guided risk management to optimize therapy and align with clinical needs. Regional Insights from UAE-Specific Data Table 5 presents UAE-specific prevalence data on obesity-related ischemia and bleeding outcomes from Bayanat, which align with national cardiometabolic health trends. [9] DAPT strategies significantly affected event rates, emphasizing AI’s role in tailoring therapy. - Extended DAPT (≥12 months) reduced ischemic events by 22% (p = 0.002). - Shortened DAPT (<6 months) increased bleeding risk by 17% (p = 0.003). Absolute and relative risk reductions (ARR and RRR) were higher with AI-optimized strategies, underscoring the clinical benefits of personalized DAPT selection. Figure 6 compares UAE-specific and global ischemic event rates, showcasing regional differences in obesity’s role in DAPT outcomes. [19] Panel A outlines the time-dependent shifts in ischemic (blue line) and bleeding (orange line) risks. Ischemic risk rises between 6–12 months, reflecting increased post-DAPT cessation vulnerability, while bleeding risk surges between 12–18 months with prolonged therapy. The prediction phase (0–6 months) transitions to a validated observational period (12–37 months), refining treatment recommendations. These trends confirm shorter DAPT reduces bleeding but heightens ischemic risks, whereas extended therapy prevents ischemia but elevates bleeding complications. Panel B illustrates patient flow from PCI to AI-driven DAPT adjustments. Of 5000 initial patients, 4200 completed follow-up, and 3100 underwent AI-based stratification. High bleeding-risk patients (n = 1100) were shifted to shorter therapy, while 2400 high ischemic-risk patients remained on extended DAPT. The final bar (n = 1800) highlights AI-optimized durations. Collectively, these findings demonstrate AI’s ability to dynamically assess risks, optimize DAPT strategies, and balance ischemic and bleeding outcomes for improved long-term results Cost-Effectiveness of AI-Based Personalization Table 6 evaluates the cost-effectiveness of AI-guided DAPT strategies, revealing reduced ischemic events at a lower cost per QALY compared to standard practices: [20] 1. Extended DAPT (≥12 months) lowered ischemic events by 22% (p = 0.002). 2. Shortened DAPT (<6 months) raised bleeding risk by 17% (p = 0.003). 3. AI-based optimization reduced combined event rates by 10%. Figure 7 illustrates the clinical benefits of AI-driven DAPT strategies: [21] - Panel A: AI approaches decreased ischemic events by 18% and bleeding complications by 12% versus standard care. - Panel B: 42% of patients received adjusted DAPT durations, with 25% switching to shorter therapy due to bleeding risk and 17% extending therapy for ischemic protection. Table 7 summarizes the study findings, linking AI-driven DAPT optimization with clinical improvements. [7] [13] Personalized approaches showed better event-free survival across all subgroups. 1. Patients following AI-DAPT recommendations experienced a 32% reduction in ischemic event risk compared to fixed-duration therapy. 2. Among high-bleeding-risk patients, AI modifications led to a 24% reduction in major bleeding complications. These results align with existing evidence supporting tailored DAPT strategies based on individual risk factors. [13] [14] The incorporation of AI in clinical decision-making is increasingly recognized for improving outcomes, as highlighted in recent cardiovascular research. Furthermore, this study emphasizes integrating genomic and environmental factors, particularly in diverse populations like the UAE, to enhance therapy personalization. [10] Discussion This study underscores the transformative impact of AI-driven strategies in personalizing dual antiplatelet therapy (DAPT) post-percutaneous coronary intervention (PCI). By leveraging clinical, procedural, and patient-specific risk data, the framework demonstrated superior accuracy in balancing ischemic and bleeding risks compared to conventional tools. [5] These advancements align with the growing role of machine learning (ML) and deep learning (DL) in predicting adverse outcomes, outstanding traditional approaches. [17] A key takeaway is the shift from static, guideline-based DAPT decisions to dynamic, AI-guided risk stratification tailored to individual needs. By incorporating real-time patient data, clinicians can dynamically adjust DAPT duration to minimize adverse events while optimizing benefits. The framework’s core innovation is its adaptability, allowing real-time updates to risk predictions for a more patient-focused treatment approach. [15][18] 4.1 Interpretation of Findings The study highlights the exceptional accuracy of its AI model in predicting ischemic and bleeding events, achieving strong performance metrics (e.g., AUC-ROC > 0.85). [5] This aligns with prior research affirming AI's role in improving post-PCI risk assessment. [17] By introducing a dynamic risk prediction system, the framework enables clinicians to personalize DAPT durations based on patient-specific data. [18] Among high-risk groups like those with diabetes or complex lesions, AI-guided DAPT adjustments led to a 25% reduction in ischemic and bleeding complications compared to standard treatments. [15] This model ensures that DAPT duration modifications are evidence-based, offering tailored decision support for physicians rather than generalized or subjective approaches. In addition, the model incorporated UAE-specific factors, including genetic variations (e.g., CYP2C19 polymorphisms) and lifestyle-related conditions like obesity and diabetes, offering unique insights into the needs of the regional population. [9] These findings emphasize the necessity of tailoring DAPT protocols to specific demographics, a perspective often absents in global guidelines. [13] By addressing real-world challenges—such as low adherence rates influenced by cultural and behavioral factors—this model enhances its practical applicability, making AI-driven DAPT personalization particularly beneficial in diverse healthcare settings. [12] 4.2 Comparison with Existing Literature This study advances prior findings in the field, such as the PATH-PCI trial, which demonstrated that ML-guided DAPT strategies reduce ischemic events without increasing bleeding risks. [15] Unlike PATH-PCI, which focused on a Western cohort, this research addresses the UAE population, offering a more globally inclusive framework. [16] While widely used, tools like PRECISE-DAPT and DAPT scores rely on stationary factors, limiting their applicability in dynamic clinical settings. [17] In contrast, the AI model offered here influences real-time data for more precise and adaptable DAPT management. [19] The study also underscores cost-effectiveness, addressing calls to integrate economic considerations into AI healthcare research. [20] By decreasing hospital readmissions and adverse events, the model demonstrated significant cost savings, aligning with insights from the ADAPT-DM registry. [18] Unlike earlier studies focused solely on clinical outcomes, this work evaluates both clinical and economic aids of AI-driven personalization. [22] 4.3 Strengths and Limitations This research stands out for its innovative application of AI in dynamic risk assessment, focus on UAE-specific factors, and holistic evaluation of clinical and economic outcomes. [5] By incorporating explainable AI (XAI), the model enhances transparency, fostering trust and adoption among healthcare professionals. [8] However, certain limitations persist: 1. Data heterogeneity poses challenges due to multiple sources with potential inconsistencies. Despite rigorous preprocessing, residual data quality issues may affect generalizability. 2. The reliance on retrospective data introduces bias, highlighting the need for prospective validation. [14] 3. While effective for the UAE population, further studies are essential to determine applicability across other regions. Region-specific models may require adjustments for different healthcare systems. [9][10] 4. Implementation hurdles include inconsistent data quality, infrastructural constraints, and achieving clinician acceptance. Successful integration with existing EHR systems demands further validation. 4.4 Future Research Directions Building on the findings of this study, several key areas for future investigation include: - Prospective Validation : Multi-center studies with larger cohorts are crucial to confirm the long-term benefits of AI-guided DAPT personalization. Randomized controlled trials (RCTs) comparing AI-driven approaches to conventional methods would offer robust evidence for clinical adoption. - Model Generalizability : To extend beyond UAE-specific populations, datasets should be expanded to include diverse global healthcare systems, enhancing external validity through cross-population comparisons. - Advanced AI Techniques : Implementing methods like federated learning could improve model performance while preserving patient privacy. Incorporating real-time biomarkers, such as platelet reactivity indices, could further refine dynamic risk assessments. - Clinical Integration : Research should focus on the real-world application of AI-based decision support, including clinician interactions and adherence to recommendations. Evaluating integration into electronic health records (EHR) systems across varied healthcare environments remains a priority. Conclusion This research highlights the practicality and benefits of employing an AI-based method to tailor dual antiplatelet therapy (DAPT) durations for patients undergoing percutaneous coronary intervention (PCI). By incorporating personalized risk assessments for ischemic and bleeding events, this approach aligns with existing evidence that supports precision medicine in interventional cardiology, underscoring the value of individualized care to enhance patient outcomes. [21] The study emphasizes the critical role of periodic risk evaluation in refining treatment strategies, thereby serving as a platform for developing advanced AI-powered decision-making tools. [15] Clinically, personalized DAPT guided by AI could bolster patient safety by reducing unnecessary extended antiplatelet therapy in low-risk patients while ensuring sufficient protection for those at higher risk. [16] This strategy has the potential to lower the incidence of major adverse cardiovascular events (MACE) and bleeding complications, offering notable advantages for both patient care and healthcare resource management.

AI model predictions (13.5%) emerge as the most influential factor in risk stratification. Clinical history, including prior IHD, MI, or bleeding events, remains crucial for predicting outcomes. Lesion complexity and stent type are key procedural factors affecting post-PCI risk, reaffirming their role in DAPT personalization. Interpreting Risk Scores: Higher ischemic scores reflect an elevated risk of recurrent events, supporting extended DAPT duration. Conversely, higher bleeding scores indicate a greater risk of hemorrhagic complications, emphasizing the need for customized DAPT strategies. Clinical Application: The model integrates clinical history, lab values, and AI predictions for real-time risk assessment. These findings advocate for personalized DAPT recommendations, guided by data-driven decision-making.

Patients aged ≥ 65, those with diabetes, or prior MI see the greatest benefit (ARR > 7.0%). While non-diabetic and non-hypertensive patients show higher baseline EFS, they still achieve 5.7-6.2% improvement with AI-guided therapy. - Risk Reduction & Statistical Significance: Relative risk reduction (RRR) spans 7.2% to 11.9%, demonstrating consistent subgroup benefits. p-values < 0.005 confirm statistically significant improvements, validating AI’s effectiveness in DAPT optimization. - Clinical Implications: AI-driven therapy supports personalized decision-making for both high- and low-risk patients. Those with diabetes, prior MI, and obesity achieve the most notable improvements, highlighting the importance of tailored approaches in secondary prevention.

Despite advances in drug-eluting stents (DES) and personalized risk scores, achieving an optimal balance balance between reducing ischemic events and minimizing bleeding complications is still complex. This is particularly evident in heterogeneous populations such as those in the United Arab Emirates (UAE), where diverse genetic, metabolic, and lifestyle factors influence cardiovascular risk. \u003cb\u003e[1] [2]\u003c/b\u003e Currently, conventional DAPT duration strategies rely on fixed-duration protocols or risk scores like the PRECISE-DAPT and DAPT scores. However, these static models lack real-time adaptability to patient-specific clinical characteristics. Recent artificial intelligence (AI)-driven approaches, including LightGBM, random forest, and logistic regression, have demonstrated superior accuracy in predicting ischemic and bleeding risks compared to traditional scoring models. \u003cb\u003e[3][4]\u003c/b\u003e Recent advancements in AI-driven risk prediction models, including LightGBM, random forest, and logistic regression, present transformative possibilities in cardiology.

Percentages represent case proportions within the 5000-patient cohort, divided into the EHR registry (3500 patients) and ICU database (1500 patients). The EHR registry includes outpatient and general cardiovascular cases, while the ICU database focuses on critically ill patients.

While current guidelines emphasize risk stratification, the integration of artificial intelligence (AI)-driven models, including LightGBM, random forest, and logistic regression, for personalized treatment recommendations has not been extensively explored. This study develops and validates an AI-driven framework that leverages UAE-specific and global datasets to refine DAPT duration and optimize post-PCI outcomes.\u003c/p\u003e\n\u003cp\u003eMethods: Patient data from the Bayanat Data Portal (UAE) and the global MIMIC-IV PhysioNet database were analyzed. Baseline characteristics, ischemic and bleeding events, and long-term clinical outcomes were assessed over a 37-month follow-up period. Among the tested AI models, LightGBM demonstrated the highest predictive accuracy compared to conventional DAPT risk scores. Kaplan-Meier survival analysis, receiver operating characteristic (ROC) curves, and feature importance analysis were used to compare risk-adjusted DAPT strategies. Cost-effectiveness was evaluated based on healthcare resource utilization and quality-adjusted life years (QALYs).\u003c/p\u003e\n\u003cp\u003eResults: Among 5,000 patients, factors such as obesity, prior myocardial infarction (MI), and genetic predispositions significantly influenced DAPT-related outcomes. LightGBM achieved an area under the curve (AUC) of 0.89, surpassing conventional risk scores (AUC: 0.75, p\u0026lt;0.001). Kaplan-Meier curves revealed a significant survival advantage for AI-personalized DAPT (log-rank p\u0026lt;0.01). Shorter DAPT durations increased ischemic risk in high-risk patients, while longer therapy heightened bleeding complications. AI-driven risk stratification reduced unnecessary medication exposure,translating into improved cost-effectiveness and optimized treatment outcomes.\u003c/p\u003e\n\u003cp\u003eConclusion: AI-based DAPT personalization significantly enhances risk prediction and clinical decision-making, outperforming traditional models. Integrating UAE-specific data ensures regional applicability, reinforcing the need for precision-driven post-PCI management. These findings support AI-powered decision support systems as a transformative approach to improving cardiovascular outcomes, warranting further validation in prospective trial\u003c/p\u003e","manuscriptTitle":"AI-Driven Personalization of Dual Antiplatelet Therapy Duration Post-PCI: A Novel Approach Balancing Ischemic and Bleeding Risks in the UAE Population","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-04-08 12:08:20","doi":"10.21203/rs.3.rs-6297676/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"ae075baf-09e3-4fc5-b9b2-3ae90117fa75","owner":[],"postedDate":"April 8th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":46545922,"name":"Cardiac \u0026 Cardiovascular Systems"}],"tags":[],"updatedAt":"2025-04-08T12:08:20+00:00","versionOfRecord":[],"versionCreatedAt":"2025-04-08 12:08:20","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-6297676","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-6297676","identity":"rs-6297676","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
