Long-term clinical outcomes among patients with cardiogenic shock (CS) and heart failure (HF) who sur-vive the early phase of acute myocardial infarction (AMI) remain uncertain. We investigated 3283 consecutive patients with AMI, selected from a prospective, nation-wide multicenter registry (J-MINUET) database compris-ing 28 institutions in Japan between July 2012 and March 2014. The 3263 eligible patients were divided into the following three groups: CS-/HF-group (n = 2467, 75.6%); CS-/HF+ group (n = 479, 14.7%); and CS+ group (n = 317, 9.7%). The thirty-day mortality rate in CS+ patients was 32.8%, significantly higher than in CS-patients. Among CS+ patients, multivariate logistic regression analysis identified statin use before admission (Odds ratio (OR) 0.32, 95% confidence interval (CI) 0.14-0.66, P = 0.002), renal deficiency (OR 8.72, 95%CI 2.81-38.67, P < 0.0001) and final thrombolysis in myocardial infarction flow grade (OR 0.42, 95%CI 0.18-0.99, P = 0.046) were associated with 30-day mortality. Landmark Kaplan-Meier analysis showed that mortality rates after 30 days were comparable between CS+ and CS-/HF+ groups but were lower in the CS-/ HF-group. Multivariate Cox hazard analysis also showed that hazard risk of mortality after 30 days was comparable between the CS+ and CS-/HF+ groups (Hazard ratio (HR) 1.03, 95%CI 0.63-1.68, P = 0.90), and significantly lower in the CS-/HF-group (HR 0.44, 95%CI 0.32-059, P < 0.0001). In conclusion, AMI patients with CS who survived 30 days experienced worse long-term outcomes compared with those without CS up to 3 years. Attention is required for patients who show HF on admission without CS to improve long-term AMI out-comes.
