Abstract Patients with STEMI may present with significant angiographically multivessel disease in 40% to 65% of the cases. For these patients, early recanalization of only the Infarct-Related Artery (IRA) by primary PCI is mandated by guidelines; however plaque instability may develop in a multifocal pattern resulting in multiple unstable coronary plaques in anatomically remote locations . Complete revascularization may prevent recurrent ischemia from ‘non-infarct-related’ lesions, obviating the need for repeat intervention, and also possibly improves the late outcome by reducing the ischemic burden following myocardial damage. Aim of the study:- to compare 6 months follow up of complete revascularization Vs culprit only in STEMI patients under went primary PCI regarding MACCE. Patient and method: In our study 50 STEMI patients with multivessel disease underwent primary PCIs in our center between November 2018 and November 2019 were divided into 2 groups: 1- Culprit only PCI . 2-Complete Revascularization during the index procedure. Mortality rates and clinical outcomes were compared between the two groups in hospital and at 6 month. Results: The study didn’t show any significant statistical difference between 2 groups regarding Total Mortality (2% vs 4 %) , Stroke (0 % in both groups) However there was reduction in the reccurence of ischeamic chest pain in the Total revascularization group (34% vs 12 %, P 0,017) and reduction in non-fatal MI (20%)vs(0%). |
