Abstract

Since late myocardial infarctions after percutaneous coronary interventions have not been well characterized, we intended to evaluate the characteristics of myocardial infarctions occurring > 48 hr after balloon angioplasty of native coronary arteries or saphenous vein grafts. The Montreal Heart Institute database (1985-1996) was interrogated for all patients readmitted with a diagnosis of MI more than 48 hr after successful percutaneous transluminal coronary angioplasty (PTCA). We compared the clinical, procedural, and angiographic variables between Mis related or not to the index PTCA site. One hundred and ninety-three patients presented with late myocardial infarction (MI) following balloon angioplasty. The median time elapsed between PTCA and MI was 55 days compared to 968 days when MI was unrelated to the PTCA site. Mis related to the PTCA site were more likely non-Q-wave (76% vs. 35%, P = 0.0001) with less marked OK-MS rise. Angiography showed less complex lesions (63% vs. 90%, P = 0.001) and better thrombolysis in myocardial infarction (TIMI) grade flow (TIMI II to III, 66% vs. 56%, P = 0.01) when the culprit lesion was at the PTCA site. Independent predictors of MI at the PTCA site were vein graft dilation, female sex, and residual stenosis post-PTCA. Myocardial infarctions occurring late after PTCA have a distinct timecourse and present specific characteristics according to their relationship or not to the previously dilated site.
