Variant (Prinzmetal) Angina

Variant (Prinzmetal) angina is rest angina due to focal coronary vasospasm causing transient ST-segment elevation, often at night/early morning, in younger patients, related to smoking/hyperventilation. Treatment: nitrates and calcium-channel blockers (vasodilators); smoking cessation; avoid beta-blockers alone (may worsen spasm); treat associated fixed atherosclerosis; risk-factor modification.

Common Symptoms

Rest angina at night/early morning; transient ST elevation during attack; younger patient; smoking-related

Causes and Pathogenesis

Focal coronary vasospasm (endothelial dysfunction/smoking) causes transient transmural ischemia.

Treatment

Nitrates/CCBs; smoking cessation; avoid beta-blockers alone; treat fixed atherosclerosis

Preventive Measures

Smoking cessation; avoid triggers; CCB prophylaxis.
