The prognostic implications of systolic time intervals after acute myocardial infarction.
STI were measured on the 7th day after acute myocardial infarction in 144 male patients. These patients were reviewed at 6 weeks and 86 were reinvestigated and reviewed at 6 months. The STI could not predict the patients who would have either angina or a further myocardial infarction. Left ventricular function, as measured by STI, appeared to be a minor factor governing return to work after myocardial infarction. Patients who had developed ventricular aneurysms at 6 months had significantly increased EMI at 6 weeks. STI on day 7 had considerable prognostic significance for left ventricular failure at 6 weeks and death between day 7 and 6 weeks and it is suggested that LVET index could be usefully, and easily, introduced as a parameter after myocardial infarction.
