Coronary revascularisation outcomes in patients with cancer

Abstract

Cancer and coronary artery disease (CAD) overlap in traditional risk factors as well as molecular mechanisms underpinning the development of these two disease states. Patients with cancer are at increased risk of developing CAD, representing a high-risk population that are increasingly undergoing coronary revascularisation. Over 1 in 10 patients with CAD that require revascularisation with either percutaneous coronary intervention or coronary artery bypass grafting have either a history of cancer or active cancer. These patients are typically older, have more comorbidities and have more extensive CAD compared with patients without cancer. Haematological abnormalities with competing risks of thrombosis and bleeding pose further unique challenges during and after revascularisation. Management of patients with concurrent cancer and CAD requiring revascularisation is challenging as these patients carry a higher risk of morbidity and mortality compared with those without cancer, often driven by the underlying cancer and associated comorbidities. However, due to variability by different types and stages of cancer, revascularisation outcomes are specific to cancer characteristics such as the timing of onset, cancer subtype and site, stage, presence of metastases, and cancer-related therapies received. Recent studies have provided insights into defining revascularisation outcomes, procedural considerations and best practices in managing patients with cancer. Nevertheless, many gaps remain that require further studies to inform clinical best practices in this population.
