Angina Pectoris

Angina pectoris is substernal chest pain/pressure due to myocardial ischemia, classified as stable (exertional, fixed stenosis), unstable (new/crescendo/rest, ACS), and variant (vasospastic). Treatment: sublingual nitroglycerin for attacks; anti-ischemic therapy (beta-blocker/CCB/nitrates); antiplatelet (aspirin) and statin; risk-factor modification; urgent angiography/revascularization for unstable/high-risk.

Common Symptoms

Substernal pressure; exertional/rest; radiates to arm/jaw; relieved by nitroglycerin; by stable/unstable/variant

Causes and Pathogenesis

Coronary insufficiency (stenosis/spasm) causes myocardial ischemia and pain.

Treatment

Nitrates; BB/CCB; aspirin/statin; risk factors; angiography/revascularization for high-risk

Preventive Measures

Risk-factor control; antiplatelet/statin; urgent evaluation of chest pain.
