The syndrome of episodic angina at rest, recurrent ST segment elevation (mean = 9 mV) and nontransmural infarction characterized by minimal serum creatine kinase (CK) (mean 243 IU; upper normal limit 132 IU) was studied in 15 patients who presented with these findings. All were initially managed with intensive nitrate and beta-receptor blocker therapy. Eleven patients underwent intraaortic balloon counterpulsation for refractory angina and 13 underwent cardiac catheterization. High grade (greater than or equal to 90%) stenosis of the proximal left anterior descending coronary artery was demonstrated in 11 patients, and coronary spasm without significant, fixed occlusive disease was noted in 2 patients. Urgent aortocoronary bypass surgery was performed in seven patients with recurrent pain or electrocardiographic injury, or both, unresponsive to maximal medical therapy. The initial mean ST segment elevation and CK elevation for this group was 10 mV and 232 IU, respectively. No surgical patient developed recurrent infarction; there was one late death after reoperation. Eight patients whose condition stabilized initially on medical therapy did not undergo urgent surgery. However, five subsequently developed large transmural anterior reinfarction despite intensive medical therapy, and three died from pump failure. These patients on medical therapy did not differ from the surgical group in magnitude of ST segment elevation or increase in serum CK. Their initial mean ST segment elevation and CK elevation were 8 mV and 254 IU, respectively (difference not significant). Thus, repetitive episodes of rest angina with marked anterior wall ST segment elevation and mild CK elevations may define a subset of patients who appear to progress rapidly from minimal nontransmural necrosis to massive transmural infarction. Prompt recognition of this syndrome, followed by cardiac catheterization and urgent aortocoronary bypass surgery, may prevent extensive cardiac muscle loss.
