Cardiologist-Performed Baseline Evaluation with an Assessment of Coronary Status for Prostate Cancer Patients Undergoing Androgen Deprivation Therapy: Impact on Newly Diagnosed Coronary Artery Disease

This retrospective study investigated newly diagnosed coronary artery disease (CAD) in prostate cancer patients treated with Androgen Deprivation Therapy and who underwent cardio-onco evaluation at a Cancer Institute. The cardio-onco evaluation included a systematic evaluation of coronary status. Among the 34 patients evaluated, 20.6% were diagnosed with CAD, often asymptomatic with a median diagnosis time of 5 months. Of the 27 patients without CAD, 44.4% underwent a therapeutic intervention by the cardiologist. Our results underscore of CAD screening in this population; however, further research is needed to determine whether routine CAD screening for these patients would result in significant clinical benefits. Background: Given the potential cardiovascular risks of androgen deprivation therapy (ADT), it is essential to identify patients who may be at an increased risk for coronary artery disease (CAD). Despite the recent ESC recommendations, there is no consensus on when to refer a patient to a cardiologist for further evaluation. Objective: To report on new diagnoses of CAD in patients with prostate cancer (PCa) requiring ADT who underwent a systematic cardio-onco evaluation with an assessment of their coronary status. Design, Setting, and Participants: This is a retrospective, monocentric study that included patients with PCa who had completed a cardio-onco evaluation with an assessment of their coronary status in the cardio-oncology department at the Western Cancer Institute, Nantes, between January 2019 and August 2022. Intervention: The baseline cardio-onco evaluation included a physical exam, transthoracic echography, and electrocardiogram, followed with a systematic evaluation of their coronary status. Outcome Measurements and Statistical Analysis: The primary objective was to determine the incidence of newly diagnosed CAD. The secondary objective was to evaluate the number of changes in cardiovascular treatment. Results and Limitations: Among the 34 patients who underwent cardio-onco evaluation, 7 (20.6%) were diagnosed with CAD, with a median time to diagnosis of 5 months. Most patients were asymptomatic, with one who experienced a myocardial infarction. Of the 27 patients without CAD, 44.4% underwent a therapeutic intervention by the cardiologist, with no cardiac deaths during follow-up. Overall, 55.9% of patients had a therapeutic intervention after the cardio-onco evaluation. Conclusions: The high incidence of newly diagnosed CAD in asymptomatic patients supports the need for screening for CAD in this population. Further research is needed to determine whether routine screening for CAD in patients receiving ADT would result in significant clinical benefits.
