coronary heart disease equivalents
Medical conditions that confer a cardiovascular risk similar to having established coronary artery disease, warranting intensive risk factor modification and treatment targets.
Full Definition
Coronary heart disease (CHD) equivalents are clinical conditions associated with a >20% 10-year risk of cardiovascular events, similar to patients with established coronary artery disease. These conditions include diabetes mellitus, peripheral arterial disease, abdominal aortic aneurysm, carotid artery disease, and chronic kidney disease. Patients with CHD equivalents should receive intensive lipid-lowering therapy with LDL cholesterol targets similar to those with documented coronary disease. This concept helps clinicians identify high-risk patients who may not have obvious cardiac symptoms but require aggressive preventive interventions. The term has evolved with updated guidelines that now use specific risk thresholds rather than categorical equivalents.
Usage
Usage note: Often abbreviated as CHD equivalents; maintain parallel structure when listing multiple equivalent conditions.
