Prevention is the cornerstone of cardiac management, but there is currently no consensus regarding the initial cardiac workup to be performed or when to refer the patient to a cardiologist. Our study aimed to report the cardiac findings of consecutive patients with prostate cancer (PCa) requiring ADT who underwent systematic cardiac workups by a cardiologist. Materials and Methods This retrospective monocentric included consecutive patients with PCa who had completed a cardiac workup (CW) in the cardio-oncology department between January 2019 and August 2022. Baseline CW, before the initiation of ADT or within the first 90 days, included a physical exam, transthoracic echography and electrocardiogram. The primary objective was to determine the number of new diagnoses of coronary artery disease (CAD). Secondary objectives included the number of other cardiac diseases and the number of introductions/changes in cardiovascular treatment. Results Sixty patients were included in our study. Characteristics of patients at the baseline CW are available in table 1. After a median follow-up of 9 months (1–36), 10 CAD were diagnosed (16.7%). The median time to diagnose CAD was 122 days (47– 339) (swimmerplot). Of the 50 patients without a diagnosis of CAD, 22 (44.0%) underwent therapeutic intervention by the cardiologist. One patient was diagnosed with atrial fibrillation requiring treatment (Beta-blockers and anticoagulation). One diabetic patient had a diagnosis of microcirculation disorder that required beta blockers. One was diagnosed with a conductive disorder requiring a pacemaker. One was diagnosed with a severe obstructive sleep apnea syndrome requiring continuous positive airway pressure, and 18 other patients had an introduction or modification of medical treatment for cardiovascular risk factors (hypertension and/or dyslipidemia). No patients died of cardiac causes during follow-up. Of the 60 patients who underwent systematic cardiac workups, 32 (53.3%) had a therapeutic intervention after this evaluation.
