Key result

This review summarizes the pathophysiology, etiology, provocation methods, and clinical role of coronary artery spasm in patients with angina pectoris, myocardial infarction, and coronary surgery.

Key Points

To review the pathophysiology, angiographic characteristics, diagnostic provocation techniques, and clinical implications of coronary artery spasm.
Synthesized pathophysiological mechanisms and coronary angiographic anatomy related to transient arterial narrowing.
Evaluated clinical utility of diagnostic provocation testing methods for eliciting coronary vasospasm.
Examined clinical outcomes across patient groups presenting with angina pectoris, acute myocardial infarction, or undergoing coronary revascularization surgery.
Coronary artery spasm produces transient epicardial lumen constriction sufficient to trigger myocardial ischemia without increases in baseline heart rate or blood pressure.
Provocation testing provides valuable diagnostic confirmation of vasospastic activity in patients evaluated via coronary angiography.
Vasospasm contributes directly to acute coronary syndromes, presenting as variant angina, precipitating myocardial infarction, and complicating surgical interventions.

Implication

May aid spasm recognition in angina, MI, and surgery; leaves open need for prospective validation of provocation and management.
