Background: The aim of this study was to assess in-hospital mortality and major adverse cardiac events (MACE) during long-term clinical follow-up of patients who developed cardiogenic shock (CS) after acute myocardial infarction (AMI) and who underwent primary percutaneous coronary intervention (PCI). Methods and Results: The data from 147 patients with CS after AMI (61.7±10.4 years, M:F=156:99) who underwent primary PCI at Chonnam National University Hospital between January 1999 and December 2002 were analyzed: clinical characteristics, coronary angiographic findings and mortality during admission, and MACE during a 1-year clinical follow-up. Of the enrolled patients, 121 patients survived (group I, M:F=94:27) and 26 died (group II, M:F=14:12) during admission. By binary logistic regression analysis, in-hospital death was associated with low Thrombolysis In Myocardial Infarction (TIMI) flow after coronary revascularization (p=0.02, odds ratio (OR)=1.3). Eighty-nine patients (60.5%) survived without MACE during the 1-year clinical follow-up and MACE was associated with a C-reactive protein (CRP) of more than 1 mg/dl (p=0.002, OR =6.3) and low TIMI flow after coronary revascularization (p<0.001, OR =7.8). Conclusions: Primary PCI achieving TIMI 3 flow reduces in-hospital death in AMI with CS. High concentration of CRP and low TIMI flow are associated with MACE during long-term clinical follow-up.
