ST segment shift in unstable angina: pathophysiology and association with coronary anatomy and hospital outcome

A Langer, MR Freeman, and PW Armstrong

Division of Cardiology, St. Michael's Hospital, Toronto, Ontario, Canada.

The significance of ST segment shift with respect to coronary anatomy and hospital outcome was evaluated in 135 patients with unstable angina. ST shift was evident in 44% of patients on admission electrocardiogram (ECG) and in 66% on Holter monitor ECG. During hospitalization, 7% of patients had myocardial infarction, 4% died and 34% had urgent coronary revascularization. By comparing patients with and without ST shift on admission ECG, an unfavorable outcome was found in 55% versus 25% (p less than 0.005), multivessel disease in 77% versus 63% (p less than 0.05) and left main coronary artery stenosis in 22% versus 7% (p less than 0.025). When patients with and without ST shift on Holter monitor ECG were compared, an unfavorable outcome was found in 48% versus 20% (p less than 0.005), multivessel disease in 76% versus 54% (p less than 0.01) and left main coronary stenosis in 18% versus 4% (p less than 0.05). The duration of ST shift was also greater in patients with 1) unfavorable outcome (129 +/- 136 versus 52 +/- 111 min, p less than 0.01); 2) multivessel disease (98 +/- 129 versus 36 +/- 90 min, p less than 0.01); and 3) left main stenosis (150 +/- 147 versus 67 +/- 114 min, p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
