Background:Although there is an increase in the use of mechanical circulatory support devices to rescue patients with acute myocardial infarction (AMI) complicated by refractory cardiogenic shock (CS), the optimal timing of the application remains controversial. Therefore, this study aimed to compare the clinical outcomes between venoarterial-extracorporeal membrane oxygenation (VA-ECMO) insertion before and after coronary revascularization in AMI patients with refractory CS.Methods and Results:A total of 253 patients with AMI who underwent revascularization therapy with VA-ECMO were included. The study population was stratified into extracorporeal cardiopulmonary resuscitation (E-CPR) before revascularization (N=106, reference cohort) and refractory CS without E-CPR before revascularization (n=147, comparison cohort). Patients with refractory CS but without E-CPR before revascularization were further divided into VA-ECMO before revascularization (N=50) and VA-ECMO after revascularization (n=97). The primary endpoint was a composite of in-hospital mortality, left ventricular assist device implantation, and heart transplantation. The primary endpoint occurred in 60 patients (40.8%) of the comparison cohort and 51 patients (48.1%) of the reference cohort. Among the comparison cohort, the primary endpoint was significantly lower in VA-ECMO before revascularization than in VA-ECMO after revascularization (32.0% vs. 49.5%, OR 0.480, 95% CI 0.235–0.982, P=0.045). A similar trend was observed after a 1-year follow up.Conclusions:Early initiation of VA-ECMO before revascularization therapy might improve clinical outcomes in patients with AMI complicated by refractory CS.

Background:Limited data are available on the clinical outcomes of medical therapy (MT) compared with revascularization in elderly patients with coronary chronic total occlusion (CTO).Methods and Results:Between March 2003 and February 2012, we retrospectively analyzed 311 patients aged ≥75 years in the Samsung Medical Center CTO registry. Among these, 153 patients were treated with MT and 158 patients with revascularization by intervention or surgery. Inverse probability of treatment weighting (IPTW) and propensity score-matching were performed. The primary outcome was cardiac death during follow-up. Median follow-up duration was 34 (interquartile range: 15–58) months. Overall, patients in the MT group were high-risk subjects. Cardiac death of 30 patients (19.6%) occurred in the MT group vs. 17 patients (10.8%) in revascularization group (P=0.027). In the multivariate analysis, there was no significant difference between groups in the rate of cardiac death (hazard ratio [HR], 1.67; 95% confidence interval [CI], 0.86–3.24, P=0.13). After adjustment with IPTW, MT showed comparable risk of cardiac death with revascularization therapy (HR, 1.26; 95% CI, 0.71–2.21, P=0.43). In the propensity score-matched population, there was no significant difference in the rate of cardiac death between the MT and revascularization groups (HR, 1.52; 95% CI, 0.76–3.07, P=0.24).Conclusions:In the treatment of CTO in elderly patients, MT alone did not increase the risk of long-term cardiac death when compared with aggressive revascularization treatment.
