Association Between Coronary Artery Disease And Clinical Outcome In Cancer Patients: A Propensity Score Matching Analysis

The aim of this study was to evaluate the prognostic value of coronary computed tomography angiography (CTA) to predict the risk of all-cause mortality in cancer patients in a propensity score matching (PSM) analysis. A total of 331 patients who previously had cancer and underwent coronary CTA from January 2015 to December 2019 were included. Multivariate Cox proportional hazards regression analysis and propensity-score matching analysis were performed. The primary endpoint was all-cause of mortality. In total, 125 with obstructive coronary artery disease (CAD) and 206 with non-obstructive CAD during a median follow-up of 3.3 years were included in this study. After PSM, age ( HR , 1.040; 95%CI, 1.001-1.081; p =0.046), smoking history ( HR , 2.344; 95%CI, 1.211-4.536; p =0.011), diabetes mellitus ( HR , 1.862; 95%CI, 1.053-3.292; p =0.033) and obstructive CAD ( HR , 1.845; 95%CI, 1.008-3.377; p =0.047) remained significant factors for all-cause mortality. Obstructive CAD evaluated by coronary CTA was found to be at higher risk for developing all-cause mortality in cancer patients.
