Revascularization improves mortality in elderly patients with acute myocardial infarction complicated by cardiogenic shock

摘要

Cardiogenic shock (AMI-CS) occurs in 2.5-6% of hospitalized patients with acute myocardial infarction (AMI), and is associated with high morbidity and mortality [1-4]. In the aftermath of the SHOCK trial [5], small observational studies reported on outcomes of elderly (> 75-year old) patients with AMI-CS (Supplement). Uncertainty however still exists regarding the benefits of early revascularization (ER) in elderly patients with AMI-CS. In the current report, we undertook aggregate data meta-analyses of short- and intermediate-term mortality outcomes to examine the impact of an ER strategy versus an initial medical stabilization (IMS) strategy in elderly patients with AMI-CS.
