Background: Data are limited regarding long-term outcomes in patients with ST-segment–elevation myocardial infarction andmultivessel disease presenting with cardiogenic shock according to revascularization strategy. We sought to compare the3-year clinical outcomes of patients with ST-segment–elevation myocardial infarction multivessel disease with cardiogenic shockand patients with multivessel percutaneous coronary intervention (PCI) and infarct-related artery (IRA)–only PCI.
Methods and Results: Of 13 104 patients from the nationwide, multicenter, prospective KAMIR-NIH (Korea Acute MyocardialInfarction Registry––National Institutes of Health) registry, we selected 659 patients with ST-segment–elevation myocardial infarctionwho had concomitant non-IRA stenosis and presented with cardiogenic shock. The primary outcome was all-cause death. MultivesselPCI was performed in 260 patients and IRA-only PCI in 399 patients. At 3 years, patients in the multivessel PCI group had a lower risk ofall-cause death (adjusted hazard ratio, 0.65; 95% CI, 0.45–0.94 [P=0.024]), all-cause death or MI (adjusted hazard ratio, 0.59; 95% CI,0.41–0.84 [P=0.004]), and non-IRA repeat revascularization (adjusted hazard ratio, 0.23; 95% CI, 0.10–0.50 [P<0.001]) than those inthe IRA-only PCI group. The results were consistent after confounder adjustment by propensity score matching and inverse probabilityweighting analysis. Landmark analysis at 1 year demonstrated that the multivessel PCI group had a lower risk of recurrent MI and non-IRA repeat revascularization beyond 1 year (log-rank P=0.030 and P=0.017, respectively) than the IRA-only PCI group.
Conclusions: In patients with ST-segment–elevation myocardial infarction and cardiogenic shock, multivessel PCI was associatedwith a lower risk of all-cause death than IRA-only PCI at 3 years, suggesting potential benefit of non-IRA revascularization duringthe index hospitalization to improve long-term clinical outcomes.
