Management of multivessel coronary disease after ST elevation myocardial infarction treated by primary angioplasty

J Interv Cardiol. 2008 Feb;21(1):1-7. doi: 10.1111/j.1540-8183.2007.00317.x. Epub 2007 Dec 12.


Background: Optimal treatment strategy of patients with ST elevation myocardial infarction (STEMI) and multivessel coronary artery disease (CAD) undergoing primary angioplasty is still unclear. Percutaneous coronary intervention (PCI) of non-culprit vessels simultaneously or soon after primary angioplasty is feasible and safe, but available data failed to consistently show a benefit in long-term clinical outcomes.

Methods: We retrospectively compared in-hospital and long-term outcomes for patients with STEMI and multivessel CAD treated by primary angioplasty with (Group 1, n=64) or without (Group 2, n=46) early, staged PCI of other angiographically significant coronary lesions. In-hospital major adverse cardiovascular events (MACE) were defined as a composite of death, periprocedural myocardial infarction after staged, elective PCI, stroke, stent thrombosis, major bleeding, and vascular complications. MACE at follow-up were defined as a composite of death, stroke, stent thrombosis, any coronary revascularization, and re-hospitalization for acute coronary syndrome.

Results: Group 1 patients underwent staged PCI 5.9 +/- 3.5 days after primary angioplasty. The mean length of follow-up was 13 months (392 +/- 236 days). The incidence of in-hospital MACE was 20.3% in Group 1 and 10.8% in Group 2 (P=0.186); the incidence of out of hospital MACE was 9.3% in Group 1 and 23.9% in Group 2 (P=0.037). In Group 1 in-hospital MACE were driven by periprocedural myocardial infarction after the elective procedure, which occurred in 15.6% of patients.

Conclusions: Our data show that multivessel, staged PCI in STEMI patients is associated with a low incidence of adverse events at follow-up but with a higher incidence of in-hospital MACE, mainly driven by periprocedural myocardial infarction during the elective procedure.
