Its impact on PH prevalence and prognosis in advanced heart failure with reduced ejection fraction (HFrEF) remains unknown. Methods We retrospectively analyzed 175 HFrEF patients evaluated for heart transplantation, all of whom underwent comprehensive invasive and non-invasive work-up. To assess the prognostic impact of the updated PH definition, survival was compared according to the presence of PH and its phenotype. Results PH was present in 83% of patients, 76% of these met CPC PH criteria. Applying the 2015 definition, 77% of patients would have had PH, with 46% of them classified as CPC PH. Presence of PH correlated with markers of advanced HFrEF course, but only larger left atrial diameter (HR 1.158; 95% CI 1.020–1.315; p = 0.024) and lower TAPSE (HR 0.811; 95% CI 0.674–0.976; p = 0.027) remained independent predictors. CPC PH patients were older, with higher prevalence of renal insufficiency, diabetes and worse central hemodynamics. Higher age (HR 1.045; 95% CI, 1.000-1.091; p = 0.048), systolic pulmonary artery pressure determined non-invasively (HR 1.064; 95% CI, 1.018–1.111; p = 0.006) and pulmonary artery wedge pressure (HR 1.131; 95% CI, 1.015–1.261; p = 0.026) were only predictors of CPC PH. Presence of both PH and CPC PH was associated with worse 2-year outcome, defined as implantation of mechanical circulatory support or all-cause mortality. Conclusions The new PH definition minimally affects PH prevalence in advanced HFrEF but substantially increases CPC PH group, which remains associated with adverse prognosis. HFrEF pre- and post-capillary pulmonary hypertension heart transplant Figures Figure 1 Figure 2 Figure 3 1. Introduction Post-capillary PH, a common component of the HF syndrome, results from passive transmission of elevated left ventricle filling pressure [ 1 ]. 2022 ESC PH guidelines redefined PH as mean pulmonary artery pressure (mPAP) > 20 mm Hg [ 2 , 3 ]. Post-capillary PH reamins being defined by pulmonary artery wedge pressure (PAWP) > 15 mm Hg, while pulmonary vascular resistance (PVR) > 2 WU defines a combined pre- and post-capillary (CPC) phenotype [ 4 , 5 ]. Pre-capillary vasculature remodelling in CPC PH, referred to as pulmonary vascular disease (PVD), contributes to right ventricular dysfunction and is associated with adverse outcomes [ 6 , 7 ]. The reported prevalence of PH in HFrEF varies widely depending on patient characteristics and diagnostic modality, ranging from 35–48% in echocardiographic studies [ 8 , 9 ] to 46–72% in invasive right-heart catheterization (RHC) studies [ 9 , 10 ]. However, these data largely reflect patients with stable or de novo HFrEF. Data regarding the prevalence of PH in advanced HFrEF are scarce. Previous RHC-based studies were conducted using earlier PH definitions. The impact of the 2022 classification on PH prevalence, phenotypes, and associated factors in advanced HFrEF remains unclear. This study aims to analyze the prevalence, characteristics, predictors of PH, its phenotypes and survival in patients with advanced chronic HFrEF according to the recent definition [ 2 ] in current era. 2. Patients and methods 2.1. Study design We retrospectively analyzed patients hospitalized between 2017 and 2020 for advanced HFrEF, regardless of disease duration. The main inclusion criterion was left ventricular systolic dysfunction, defined as left ventricular ejection fraction (LVEF) < 40%. Exclusion criteria were as follows: age < 18 years, patients with an LVAD, patients with severe lung disease (total lung capacity < 60% of predicted, forced expiratory volume < 60% of predicted, the need for long-term oxygen therapy or PaO2 < 60 mmHg). All patients underwent RHC. Selected clinical, anthropometric, laboratory, electrocardiographic, echocardiographic, and hemodynamic data were extracted from the medical records maintained in a standard protocol manner [ 11 ]. 2.2. Right heart catheterization methodology Right heart catheterization (RHC) was performed using a Swan-Ganz thermodilution catheter under standard conditions within 24 hours of echocardiography and peripheral blood sampling. In patients with congestive signs, RHC was performed after achieving euvolemia. 2.3. Definitions Patients were classified into one of three groups according to the ESC guidelines (2) - patients in whom invasive testing did not prove the presence of PH, patients with IPC PH and CPC PH respectively. The IPC PH was defined as mPAP > 20 mm Hg, PAWP > 15 mm Hg, PVR ≤ 2 WU. If PVR was > 2 WU, patients were classified as CPC PH. For survival analysis, 2-year survival was assessed, with the endpoint defined as either mechanical circulatory support implantation or all-cause mortality. Urgent heart transplantation is not available in our region and was therefore not considered a relevant endpoint. 2.4. Statistics Continuous variables are expressed as mean ± SD and categorical variables as n (%). Group differences were assessed using Student’s t-test or chi-square test. Logistic regression was used to identify variables associated with PH phenotypes, presented as odds ratios (OR). Survival analysis was performed using Kaplan–Meier estimates and Cox proportional hazards regression, with results expressed as hazard ratios (HR). A p-value < 0.05 was considered statistically significant. The predictive performance of non-invasive sPAP for CPC PH was assessed using receiver operating characteristic (ROC) curves and the area under the curve (AUC). 3. Results 3.1. Baseline characteristics A total of 175 patients were enrolled (39 women). The predominant etiology was dilated cardiomyopathy, followed by ischemic heart disease. Less frequent causes included hypertensive heart disease, burnt-out hypertrophic cardiomyopathy, non-compaction cardiomyopathy, chronic myocarditis, and valvular heart disease. The median age was 54 years, and mean LVEF was 21.9 ± 6.7%. The mean duration from HF diagnosis to RHC was 112 ± 103 months. Most patients were in NYHA class III (124 patients) or class IV (40 patients). Baseline clinical characteristics are summarized in Table 1 . Table 1 Baseline characteristics Number of pts 175 Men (n/%) 136/78 Age (years) 54.1 ± 10.8 HF etiology DCMP (n/%) 73 (42) CAD (n/%) 66 (38) Other (n/%) 36 (20) Duration of the HF (months) 112 ± 103 LVEF (%) 21.9 ± 6.7 NYHA I/II/III/IV (n) 0/11/124/40 CAD, coronary artery disease, DCMP, dilated cardiomyopathy, HF, heart failure, LVEF, left ventricle ejection fraction, NYHA, New York Heart Association 3.2. Non-invasive and invasive characteristics Post-capillary PH was present in 83% of patients, with 24% of them classified as IPC PH and 76% as CPC PH (Fig. 1 ). Patients with PH had longer HF duration, lower blood pressure. Echocardiography revealed more advanced cardiac remodeling, including larger left atrium and right ventricle with impaired systolic function. PH patients were more likely to have moderate or severe mitral regurgitation (MR), while there was no significant difference in either the presence or the severity of tricuspid regurgitation (TR), but a trend could be observed (p = 0.06). PH was also associated with a higher prevalence of atrial fibrillation and renal insufficiency (KDIGO G2–G5, defined as eGFR < 90 mL/min/1.73 m²). Among laboratory markers, PH was linked to lower serum sodium and higher concentrations of NT-proBNP, uric acid (UA), and liver enzymes gamma-glutamyl transferase (GMT), serum bilirubin (bil). The only electrocardiographic parameter showing significant difference was a wider QRS complex in PH group. Lung function parameters (FEV₁, FVC, FEV₁/FVC) were comparable between groups. Hemodynamic parameters were not compared between PH and non-PH patients, as differences in pulmonary pressures inherently define PH. CPC PH patients were older, had lower exercise capacity, and a higher prevalence of renal insufficiency and type 2 diabetes. Among non-invasive parameters, only higher sPAP differentiated CPC PH from IPC PH. Hemodynamic impairment was more pronounced in CPC PH, while RAP did not differ between groups (10.9 ± 6.2 vs 11.9 ± 5.4 mm Hg; p = 0.37). Detailed data are provided in Tables 2 and 3 .

For the CPC PH phenotype, age and sPAP were the only independent non-invasive predictors, while PAWP was the only independent invasive predictor. For differentiating post-capillary PH phenotypes, an sPAP value > 55 mm Hg obtained by echocardiography identified CPC PH with moderate accuracy (C-statistic 0.76; sensitivity 47%; specificity 81%). 3.4. Prognostic value of the new PH definiton For survival analysis, patients who underwent non-urgent heart transplantation (HTx) were excluded, as many of them might have had advanced yet relatively stable HFrEF course. In total, 42 patients received HTx (11 with IPC PH, 26 with CPC PH and 5 without PH). The median interval between the first RHC and HTx was 1006 ± 215 days in patients without PH, 397 ± 301 days in those with IPC PH and 183 ± 128 days in the CPC PH group. The primary endpoint was a composite of all-cause mortality, urgent listing for HTx, or urgent mechanical circulatory support (MCS) implantation. During follow-up, 59 patients died, 34 required MCS implantation, and 2 were listed as urgent HTx candidates. The median time from the reference RHC to the endpoint was 775 ± 710 days. Survival according to PH presence is shown in Fig. 2 . Two-year survival was assessed from the reference RHC. One-year mortality was 36% in patients with PH and 3% in patients without PH; two-year mortality was 53% and 12%, respectively. A significant difference in survival was also observed across PH phenotypes (p = 0.039) (Fig. 3 ). In the IPC PH group, one-year mortality was 21% compared with 38% in the CPC PH group. After two years, mortality increased to 37% in IPC PH and 62% in CPC PH. 4. Discussion 4.1. PH prevalence according to the new definition Applying the new definition, PH was present in 83% of patients, compared with 77% using the previous mPAP ≥ 25 mm Hg threshold, indicating minimal impact on overall prevalence. The slightly lower prevalence of PH, 77% [ 8 ], resp. 68% [ 12 ] in patients with HF according to the findings of other authors is probably related to less advanced HF in the populations studied and not to the definition of PH being valid at the time. Using the lower mPAP as the PH defining criterion, PH was present in 62% [ 13 ] and 64% [ 14 ] of patients with less advanced stages of HFrEF. A recent multicenter study reported a modest increase in PH prevalence with the updated criteria, although comparison is limited by a high proportion of HFpEF patients [ 15 ]. Overall, these findings suggest that PH prevalence in HF is driven primarily by disease severity and patient characteristics rather than the specific mPAP cutoff. Our results further support that PH represents a common feature of advanced HFrEF even in the modern therapeutic era of HF. Lowering the PVR threshold for CPC PH represents a more impactful change. This modification was largely based on data showing increasing risk of death and hospitalization from PVR ≥ 2.2 WU, although this association was less pronounced in post-capillary PH [ 16 ]. Therefore, it can be debated whether a different, higher, PVR cut-off value should be chosen to express clinically significant PVD in patients with post-capillary PH. In our cohort, applying the new criteria led to a disproportionate increase in CPC PH prevalence (76%), compared with 46% using the 2015 definition. Similarly, Fauvel et al. reported a disproportionate rise in CPC PH prevalence from 42% to 67% when adopting the lowered PVR threshold. 4.2. Predictors of PH The high prevalence of PH in our cohort reflects the advanced stage of HFrEF [ 17 ], with up to 94% of patients being in NYHA classIII/IV. The presence of PH was associated with a prognostically unfavourable patient profile - lower systolic blood pressure, lower LVEF, higher natriuretic peptide and UA levels [ 18 ]. Several studies, including meta-analyses, have shown that elevated serum UA levels predict increased risk of death and hospitalizations for PH [ 19 – 21 ] and inversely correlate with CO [ 22 , 23 ]. The impact of MR on the development of PH in the context of HFrEF is well known [ 24 ], as confirmed by our results showing the association of PH with moderate and severe MR. Moderate or severe MR has been shown to be an independent predictor of PH in the group of patients with advanced HFrEF, along with TR and the duration of disease [ 25 , 26 ]. Right ventricular (RV) dysfunction represents a downstream consequence of PH, potentially affect peripheral organ functions [ 27 – 30 ]. RV dysfunction was more pronounced in PH affected patients, accompanied by a cholestatic laboratory profile consistent with advanced right-sided HF. Finally, QRS prolongation was associated with PH, likely reflecting more advanced myocardial remodeling and its known link to worse prognosis [ 31 , 32 ]. 4.3. Predictors of CPC PH Distinguishing IPC PH from CPC PH using clinical and non-invasive parameters remains challenging. CPC PH was more frequent in older patients and those with diabetes and renal insufficiency. The association of an older age and renal insufficiency with impaired pulmonary vasculature previously described in HFpEF patients [ 33 ] likely reflects proinflammatory state leading to the endothelial dysfunction rather than pulmonary disease [ 34 , 35 ]. Consistently, spirometric parameters did not differ between groups, supporting a limited role of primary lung pathology. Among non-invasive measures, only sPAP differentiated PH phenotypes, with values > 55 mm Hg identifying CPC PH with acceptable accuracy. This finding may facilitate non-invasive phenotyping and patient selection in studies targeting PVD as therapeutic target in HFrEF. 4.4. Outcomes according to the hemodynamic profile PH in HF is a strong determinant of mortality irrespective of LVEF. In our cohort, its adverse prognostic impact persisted despite the lower mPAP threshold, with CPC PH consistently identifying a subgroup at substantially higher risk compared with IPC PH. These results suggest that the CPC PH phenotype may warrant consideration as an additional factor when prioritizing patients on the heart transplant waiting list. To our knowledge, this is the first study to evaluate survival in patients with advanced HF and PH using the modified hemodynamic classification of post-capillary PH. Evidence regarding outcomes in patients with advanced HFrEF and CpcPH remains scarce. A subanalysis of the ESCAPE trial showed no difference in mortality between patients with advanced HFrEF and CpcPH—defined by PVR ≥ 3 WU—and those with PH and PVR < 3 WU [ 36 ]; however, the follow-up period was limited to only 6 months. More recent data examining the impact of the updated PH definition across HF populations, regardless of LVEF, demonstrated significantly worse outcomes in CPC PH even when applying a lower PVR threshold [ 15 ], consistent with our findings.Taken together, these findings suggest that the revised PH definition not only refines hemodynamic classification but also enhances prognostic discrimination, particularly by identifying a high-risk CPC PH phenotype across the HF spectrum. 5. Conclusions The new PH definition has minimal impact on overall PH prevalence in HF but leads to a marked increase in CPC PH, expanding its heterogeneity, which may affect design of future clinical trials targeting the pre-capillary component of PH, such as studies evaluating PAH-specific therapies in post-capillary PH. Non-invasive identification of PVD will therefore be challenging, although sPAP > 55 mm Hg emerged as a useful discriminator in advanced HFrEF. However, the revised definition retains prognostic value by identifying a high-risk CPC PH phenotype, with potential implications for patient monitoring and therapeutic decision-making.

PH prevalence according to the new definition\u003c/h2\u003e \u003cp\u003eApplying the new definition, PH was present in 83% of patients, compared with 77% using the previous mPAP\u0026thinsp;\u0026ge;\u0026thinsp;25 mm Hg threshold, indicating minimal impact on overall prevalence. The slightly lower prevalence of PH, 77% [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e], resp. 68% [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e] in patients with HF according to the findings of other authors is probably related to less advanced HF in the populations studied and not to the definition of PH being valid at the time. Using the lower mPAP as the PH defining criterion, PH was present in 62% [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e] and 64% [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e] of patients with less advanced stages of HFrEF. A recent multicenter study reported a modest increase in PH prevalence with the updated criteria, although comparison is limited by a high proportion of HFpEF patients [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Overall, these findings suggest that PH prevalence in HF is driven primarily by disease severity and patient characteristics rather than the specific mPAP cutoff. Our results further support that PH represents a common feature of advanced HFrEF even in the modern therapeutic era of HF.\u003c/p\u003e \u003cp\u003eLowering the PVR threshold for CPC PH represents a more impactful change. This modification was largely based on data showing increasing risk of death and hospitalization from PVR\u0026thinsp;\u0026ge;\u0026thinsp;2.2 WU, although this association was less pronounced in post-capillary PH [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e]. Therefore, it can be debated whether a different, higher, PVR cut-off value should be chosen to express clinically significant PVD in patients with post-capillary PH. In our cohort, applying the new criteria led to a disproportionate increase in CPC PH prevalence (76%), compared with 46% using the 2015 definition. Similarly, Fauvel et al. reported a disproportionate rise in CPC PH prevalence from 42% to 67% when adopting the lowered PVR threshold.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec14\" class=\"Section2\"\u003e \u003ch2\u003e4.2. Predictors of PH\u003c/h2\u003e \u003cp\u003eThe high prevalence of PH in our cohort reflects the advanced stage of HFrEF [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e], with up to 94% of patients being in NYHA classIII/IV. The presence of PH was associated with a prognostically unfavourable patient profile - lower systolic blood pressure, lower LVEF, higher natriuretic peptide and UA levels [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]. Several studies, including meta-analyses, have shown that elevated serum UA levels predict increased risk of death and hospitalizations for PH [\u003cspan additionalcitationids=\"CR20\" citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e] and inversely correlate with CO [\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e, \u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e]. The impact of MR on the development of PH in the context of HFrEF is well known [\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e], as confirmed by our results showing the association of PH with moderate and severe MR. Moderate or severe MR has been shown to be an independent predictor of PH in the group of patients with advanced HFrEF, along with TR and the duration of disease [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e, \u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e]. Right ventricular (RV) dysfunction represents a downstream consequence of PH, potentially affect peripheral organ functions [\u003cspan additionalcitationids=\"CR28 CR29\" citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e]. RV dysfunction was more pronounced in PH affected patients, accompanied by a cholestatic laboratory profile consistent with advanced right-sided HF. Finally, QRS prolongation was associated with PH, likely reflecting more advanced myocardial remodeling and its known link to worse prognosis [\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e, \u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e].\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec15\" class=\"Section2\"\u003e \u003ch2\u003e4.3. Predictors of CPC PH\u003c/h2\u003e \u003cp\u003eDistinguishing IPC PH from CPC PH using clinical and non-invasive parameters remains challenging. CPC PH was more frequent in older patients and those with diabetes and renal insufficiency. The association of an older age and renal insufficiency with impaired pulmonary vasculature previously described in HFpEF patients [\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e] likely reflects proinflammatory state leading to the endothelial dysfunction rather than pulmonary disease [\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e, \u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e]. Consistently, spirometric parameters did not differ between groups, supporting a limited role of primary lung pathology. Among non-invasive measures, only sPAP differentiated PH phenotypes, with values\u0026thinsp;\u0026gt;\u0026thinsp;55 mm Hg identifying CPC PH with acceptable accuracy. This finding may facilitate non-invasive phenotyping and patient selection in studies targeting PVD as therapeutic target in HFrEF.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec16\" class=\"Section2\"\u003e \u003ch2\u003e4.4. Outcomes according to the hemodynamic profile\u003c/h2\u003e \u003cp\u003ePH in HF is a strong determinant of mortality irrespective of LVEF. In our cohort, its adverse prognostic impact persisted despite the lower mPAP threshold, with CPC PH consistently identifying a subgroup at substantially higher risk compared with IPC PH. These results suggest that the CPC PH phenotype may warrant consideration as an additional factor when prioritizing patients on the heart transplant waiting list. To our knowledge, this is the first study to evaluate survival in patients with advanced HF and PH using the modified hemodynamic classification of post-capillary PH. Evidence regarding outcomes in patients with advanced HFrEF and CpcPH remains scarce. A subanalysis of the ESCAPE trial showed no difference in mortality between patients with advanced HFrEF and CpcPH\u0026mdash;defined by PVR\u0026thinsp;\u0026ge;\u0026thinsp;3 WU\u0026mdash;and those with PH and PVR\u0026thinsp;\u0026lt;\u0026thinsp;3 WU [\u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e]; however, the follow-up period was limited to only 6 months. More recent data examining the impact of the updated PH definition across HF populations, regardless of LVEF, demonstrated significantly worse outcomes in CPC PH even when applying a lower PVR threshold [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e], consistent with our findings.Taken together, these findings suggest that the revised PH definition not only refines hemodynamic classification but also enhances prognostic discrimination, particularly by identifying a high-risk CPC PH phenotype across the HF spectrum.\u003c/p\u003e \u003c/div\u003e"},{"header":"5. Conclusions","content":"\u003cp\u003eThe new PH definition has minimal impact on overall PH prevalence in HF but leads to a marked increase in CPC PH, expanding its heterogeneity, which may affect design of future clinical trials targeting the pre-capillary component of PH, such as studies evaluating PAH-specific therapies in post-capillary PH. Non-invasive identification of PVD will therefore be challenging, although sPAP\u0026thinsp;\u0026gt;\u0026thinsp;55 mm Hg emerged as a useful discriminator in advanced HFrEF.

To assess the prognostic impact of the updated PH definition, survival was compared according to the presence of PH and its phenotype.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003ePH was present in 83% of patients, 76% of these met CPC PH criteria. Applying the 2015 definition, 77% of patients would have had PH, with 46% of them classified as CPC PH. Presence of PH correlated with markers of advanced HFrEF course, but only larger left atrial diameter (HR 1.158; 95% CI 1.020\u0026ndash;1.315; p\u0026thinsp;=\u0026thinsp;0.024) and lower TAPSE (HR 0.811; 95% CI 0.674\u0026ndash;0.976; p\u0026thinsp;=\u0026thinsp;0.027) remained independent predictors. CPC PH patients were older, with higher prevalence of renal insufficiency, diabetes and worse central hemodynamics. Higher age (HR 1.045; 95% CI, 1.000-1.091; p\u0026thinsp;=\u0026thinsp;0.048), systolic pulmonary artery pressure determined non-invasively (HR 1.064; 95% CI, 1.018\u0026ndash;1.111; p\u0026thinsp;=\u0026thinsp;0.006) and pulmonary artery wedge pressure (HR 1.131; 95% CI, 1.015\u0026ndash;1.261; p\u0026thinsp;=\u0026thinsp;0.026) were only predictors of CPC PH. Presence of both PH and CPC PH was associated with worse 2-year outcome, defined as implantation of mechanical circulatory support or all-cause mortality.\u003c/p\u003e\u003ch2\u003eConclusions\u003c/h2\u003e \u003cp\u003eThe new PH definition minimally affects PH prevalence in advanced HFrEF but substantially increases CPC PH group, which remains associated with adverse prognosis.\u003c/p\u003e","manuscriptTitle":"Pulmonary hypertension in advanced heart failure with reduced ejection fraction.
