Does Infarct Size Matter?

There is very extensive published data employing clinical parameters, angiographic variables, assessment of left ventricular function, and stress testing to identify patients who are at higher risk for cardiac events after ST-segment elevation myocardial infarction (STEMI). Most importantly, this incremental analysis was done in a very rigorous fashion, with consideration of clinical (age, sex, risk factors), angiographic (left anterior descending or non-left anterior descending infarct vessel, baseline TIMI [Thrombolysis In Myocardial Infarction] flow) and treatment (symptom-to-first device time) variables that have been demonstrated in previous studies to be of prognostic importance.
