A clinical trial comparing complete revascularization at the time of primary percutaneous coronary intervention versus during the index hospital admission in patients with multi-vessel coronary artery disease and STEMI uncomplicated by cardiogenic shock

Objective: In this study, we aimed to compare major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of death, stroke, myocardial infarction and symptom-induced revascularization, and mortality within one year of randomization between two strategies; complete revascularization including non-culprit lesions percutaneous coronary intervention (PCI) during primary PCI (PPCI) versus complete revascularization during the same hospital admission in patients with multi-vascular coronary artery disease (MVD) presenting with ST-elevation myocardial infarction (STEMI) uncomplicated by cardiogenic shock.
Methods: We randomized in a 1: 1 manner 100 patients with MVD and STEMI uncomplicated by cardiogenic shock who had undergone successful culprit-lesion PCI to either a strategy of complete revascularization with PCI of angiographically significant non-culprit lesions in the index PPCI procedure or to a strategy of complete revascularization during a second procedure that took place during the same hospital admission.
Results: The first primary outcome was death within a timeframe of one year and the second a composite of MACCE within a year following complete revascularization. Of the total number of patients monitored, 4% in each of the two groups was associated with the first primary outcome (p=0.984) and the second primary outcome in 6% (p=0.970). There was no statistical difference between outcomes in the two groups.
Conclusion: Among patients with MVD and STEMI uncomplicated by cardiogenic shock, there was no difference regarding outcomes when using a strategy of complete revascularization of non-culprit lesions during PPCI or the same hospital admission.
