Abstract:
Objective To investigate the clinical outcomes of an invasive strategy for elderly (aged≥75 years) patients with acute ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). Methods Data on 366 of 409 elderly CS patients from a total of 6,132 acute STEMI cases enrolled in the Korea Acute Myocardial Infarction Registry between January 2008 and June 2011, were collected and analyzed. In-hospital deaths and the 1-month and 1-year survival rates free from major adverse cardiac events (MACE;defined as all cause death, myocardial infarction, and target vessel revascularization) were reported for the patients who had undergone invasive (n=310) and conservative (n=56) treatment strategies. Results The baseline clinical characteristics were not significantly different between the two groups. There were fewer in-hospital deaths in the invasive treatment strategy group (23.5%vs. 46.4%, P＜0.001). In addition, the 1-year MACE-free survival rate after invasive treatment was significantly lower compared with the conservative treatment (51%vs. 66%, P=0.001). Conclusions In elderly patients with acute STEMI complicated by CS, the outcomes of invasive strategy are similar to those in younger patients at the 1-year follow-up.
