STEMI and multivessel disease: medical therapy amplifies the benefit of complete myocardial revascularization
EUROPEAN HEART JOURNAL SUPPLEMENTS(2021)
Abstract
Abstract Aims Patients with ST-elevation myocardial infarction (STEMI) with multivessel disease (MVD) may be treated with different revascularization strategies. However, the potential predictors of outcomes on top of different revascularization strategies are poorly studied. This study aimed to evaluate the prognostic impact of two different revascularization strategies and the potential impact of medical therapy. Methods and results Using a propensity score approach, the impact of two treatment strategies was analysed—staged non-culprit revascularization group vs. culprit-lesion-only percutaneous coronary intervention (PCI) group—on a composite outcome of cardiovascular death (CVD), myocardial infarction, and repeated revascularization. Moreover, models were further adjusted for medication at discharge. Among 1385 STEMI patients treated with primary PCI, a subgroup of 433 with MVD was analysed. At the median follow-up of 41 (IQR, 21–65) months, after propensity-score adjustment, the multivariable Cox proportional hazard analysis showed that the staged non-culprit revascularization group was associated with a lower composite endpoint (HR, 0.44; 95% CI, 0.24–0.82; P = 0.01), lower CVD (HR, 0.34; 95% CI, 0.14–0.82; P = 0.02), and lower all-cause death (HR, 0.46; 95% CI, 0.24–0.86; P = 0.02). Use of renin–angiotensin inhibitors was associated with lower CVD (HR, 0.51; 95% CI, 0.27–0.95; P = 0.03), and both renin–angiotensin inhibitors (HR, 0.52; 95% CI, 0.32–0.86; P = 0.01) and beta blockers (HR, 0.48; 95% CI, 0.29–0.79; P = 0.01) were associated with lower all-cause death. Conclusions In a real-word STEMI population with multivessel disease, staged non-culprit revascularization was associated with lower cardiovascular mortality compared with a culprit-only PCI strategy. However, both revascularization and medical therapy played a role in the improvement of mortality outcomes. Medical therapy amplified the benefit of myocardial revascularization.
