Acute Coronary Syndrome Management in Cancer Patients

Abstract

Purpose of Review

Coronary artery disease and cancer often co-exist. Patients with cancer have been excluded by most major cardiology trials and registries and their management remains largely empiric. Cancer patients experience an approximately 10-times increased mortality compared to the general population. Conservative therapy of ACS in cancer therapy results in 1-year mortality of 74%. This review article aims to describe the mechanisms of acute coronary syndromes in cancer patients, their clinical presentation, and their management.

Recent Findings

Newer studies have shed light on the mechanisms of ACS in cancer patients, which are different and related to the type of malignancy and its associated therapy. Medication-specific coronary effects (vasospasm, endothelial dysfunction, spontaneous thrombosis, accelerated atherosclerosis), radiation vasculitis, cancer cell coronary embolism, and coronary compression from thoracic malignancies are unique ACS mechanisms in cancer patients.

Summary

Close collaboration between oncologists and cardiologists for thoughtful patient selection and decision making strategies is necessary to provide optimal medical care.
