Abstract
By definition, chronic stable angina is angina that has been stable with regard to frequency and severity for at least 2 months. Chronic stable angina is the initial manifestation of coronary heart disease in approximately 50% of patients. Typically, this type of angina occurs in the setting of atherosclerotic coronary arterial narrowing, although other causes are possible. This review covers the epidemiology, pathophysiology, initial evaluation, differential diagnosis, management, and treatment of patients with chronic stable angina. Figures show noninvasive testing and the probability of coronary artery disease; diagnosis of patients with suspected ischemic heart disease; probability of severe coronary artery disease; coronary outcomes for high- versus low-intensity statin therapy; optimal medical therapy (OMT) versus OMT and percutaneous coronary intervention for chronic angina; OMT versus percutaneous coronary intervention for stable coronary heart disease; and coronary artery bypass grafting versus percutaneous coronary intervention for diabetes and coronary artery disease. Tables list the grading of angina pectoris by the Canadian Cardiovascular Society classification system, the differential diagnosis of chest pain, conditions promoting myocardial oxygen supply and demand mismatch, the features of typical angina, the classification of chest pain, a comparison of the pretest likelihood of coronary heart disease (CHD) in low-risk and high-risk symptomatic patients, the posttest probability of significant CHD based on pretest probabilities of CHD and normal or abnormal results of noninvasive studies, survival according to risk groups based on Duke treadmill scores, high- and moderate-intensity statin therapy, revascularization to improve survival compared with medical therapy, revascularization to improve symptoms with significant anatomic (≥ 50% left main or ≥ 70% nonleft main coronary artery disease) or physiologic (fractional flow reserve ≤ 0.80) coronary artery stenoses, and questions recommended by an expert panel for patients with chronic stable angina at follow-up visits. This review contains 7 highly rendered figures, 12 tables, and 109 references.
