Incidence, predictors, and outcome of new, subsequent lesions treated with percutaneous coronary intervention in patients presenting with myocardial infarction.

Despite improving strategies for control of risk factors, progression of atherosclerosis may lead to recurrent cardiac events related to a lesion other than that treated with initial percutaneous coronary intervention (PCI) after ST-elevation myocardial infarction (STEMI). Of 1,007 consecutive patients undergoing primary or rescue PCI for STEMI, 897 who were discharged alive were followed for up to 3 years. Those who underwent nontarget lesion revascularization (non-TLR) were compared with those who did not.
