Coronary angiographic, echocardiographic, and electrocardiographic studies on a patient with variant angina due to coronary artery spasm.
A 45-year-old Caucasian female patient with a clinical rehistory and ECG's conforming to the syndrome of variant angina as characterized by Prinzmetal is presented. ECG's recorded during spontaneous pain demonstrated ST-segment elevation and symmetrical peaking of the T-waves in the lateral precordial leads and short runs of ventricular tachycardia. Similar ECG changes were recorded during treadmill exercise- and hand-grip exercise-induced chest pain. An echocardiogram recorded during angina induced by hand-grip exercise demonstrated progressive flattening of septal motion. Multiple views of the coronary system by selective coronary cineangiography were normal with the patient at rest. Angina was then induced by hand-grip exercise and a repeat right anterior oblique view of the left coronary system revealed marked spasm of the left anterior descending artery proximal to the first septal perforator.
