Key result
Coronary arterial spasm of different degrees was angiographically confirmed as the cause of chest pain and both ST segment depression and elevation in a patient with angina at rest.
Coronary artery spasm of varying degrees can cause both ST segment depression and elevation during angina at rest.
Coronary spasm may produce mixed ST changes in rest angina; leaves open prevalence and mechanisms beyond this case.
Chest pain induced by ergometrine was associated with ST depression and subsequent elevation in anterior leads in a 42-year-old man suffering from angina at rest. Coronary arteriography during the attack showed that coronary arterial spasm of different degrees was responsible for chest pain and both types of electrocardiographic abnormality.
