Differences in postthrombolysis outcome between Q-wave and non-Q-wave myocardial infarction

Research output: Contribution to journalArticlepeer-review


The clinical outcomes of Q-wave versus non-Q-wave myocardial infarction were compared in a study of 139 patients treated with thrombolytic agents. Patients were classified as having Q-wave or non-Q-wave infarction based on both 24-hour and hospital-discharge electrocardiograms. At 24 hours, 80% of the patients had pathological Q waves. Subsequently, Q waves regressed in 18 patients and developed in seven. The 24-hour classification was not associated with any significant clinical or prognostic information. Classification based on the discharge electrocardiogram, however, showed that, although non-Q-wave infarction was associated with higher rates of hospital readmission and revascularization procedures, it was also characterized by smaller infarcts, improved left ventricular function, and somewhat lower mortality compared with Q-wave infarction.
