Background:Because ST-elevation myocardial infarction (STEMI) extensively damages the heart, regenerative therapy with pluripotent stem cells such as multilineage-differentiating stress enduring (Muse) cells is required.Methods and Results:In a first-in-human study, 3 STEMI patients with a left ventricular ejection fraction (LVEF) ≤45% after successful percutaneous coronary intervention received intravenously 1.5×107cells of a human Muse cell-based product, CL2020. The safety and efficacy on LVEF and wall motion score index (WMSI) were evaluated for 12 weeks. No adverse drug reaction was noted. LVEF and WMSI were markedly improved.Conclusions:The first-in-human intravenous administration of CL2020 was safe and markedly improved LV function in STEMI patients.

Background:Data regarding the clinical features, outcomes and prognostic factors in patients presenting with acute total/subtotal occlusion of the unprotected left main coronary artery (LMCA) remain limited.Methods and Results:From a multi-center registry, 134 patients due to acute total/subtotal occlusion of the unprotected LMCA were reviewed. Emergency room (ER) status classification was defined according to the presence of cardiogenic shock and cardiopulmonary arrest (CPA) in the ER (class 1=no cardiogenic shock; class 2= cardiogenic shock but not CPA; and class 3=CPA). In-hospital mortality and cerebral performance category (CPC) as the endpoints were evaluated. One-half (67/134) of the enrolled patients presented with total occlusion of the unprotected LMCA. Regarding ER status classification, class 1, 2, and 3 were observed in 30.6%, 45.5%, and 23.9% of the patients, respectively. In-hospital mortality occurred in 73 (54.5%) patients; of the remaining patients, 52 (85.3%) could be discharged with a CPC 1 or 2. ER status classification (odds ratio 4.4 [95% confidence interval: 2.33–10.67]; P<0.001) and total occlusion of the unprotected LMCA (odds ratio 8.29 [95% confidence interval 2.93–23.46]; P<0.001) were strong predictors of in-hospital mortality.Conclusions:Acute total/subtotal occlusion involving the unprotected LMCA appeared to be associated with high in-hospital mortality. ER status classification and initial flow in the unprotected LMCA were significant predictive factors of in-hospital mortality.
