Coronary Atherosclerosis in Patients With Cancer and Survivors: A Scientific Statement From the American Heart...

There is an emerging convergence between atherosclerotic cardiovascular disease and cancer, driven by shared risk factors and overlapping pathophysiologic mechanisms. Traditional factors, such as smoking, aging, obesity, hypertension, and diabetes, alongside novel markers, such as clonal hematopoiesis of indeterminate potential, not only predispose individuals to both malignancies and coronary atherosclerosis but also amplify the risk of cardiotoxicity from cancer therapies. Inflammatory processes play a central role in atherogenesis, a process further accelerated by oncologic treatments-including chemotherapy (eg, anthracyclines, 5-fluorouracil), targeted and hormone therapies (eg, tyrosine kinase inhibitors, androgen deprivation, aromatase inhibitors), immune checkpoint inhibitors, and radiation therapy (RT)-that contribute to endothelial dysfunction and plaque instability. This scientific statement synthesizes the evidence on the interplay between cancer and coronary atherosclerosis, highlighting advances in noninvasive imaging modalities (ie, cardiac CT, nuclear imaging, cardiac magnetic resonance, echocardiography) for early detection, risk stratification, and surveillance of coronary artery disease in oncologic populations, and examines the role of invasive imaging techniques in guiding revascularization decisions. Given the elevated bleeding and thrombotic risks in these patients, individualized management of post-percutaneous coronary intervention medications and abbreviated dual antiplatelet therapy regimens is emphasized. This scientific statement also addresses knowledge gaps and reinforces the need for more evidence to improve risk stratification for atherosclerotic cardiovascular disease in patients with cancer. The shared pathobiology between coronary atherosclerosis and cancer necessitates an integrated, multidisciplinary approach to screening, diagnosis, and management.
