Coronary Spasm: Definition, Uses, and Clinical Overview
Coronary Spasm is a sudden, temporary tightening of a coronary artery. It can reduce blood flow to part of the heart muscle for minutes at a time. It is most commonly discussed as a cause of chest pain and ischemia with little or no fixed blockage. Clinicians also refer to it when evaluating angina-like symptoms, abnormal ECG changes, or unexplained cardiac events.
