BackgroundCardiogenic shock complicating ST elevation myocardial infarction is burdened by a high mortality. There is only limited evidence for the management except for early revascularization and the relative ineffectiveness of intra-aortic balloon pump.AimOur objectives were to evaluate outcome and predictors of early all-cause 30-day mortality in the setting of cardiogenic shock complicating ST elevation myocardial infarction.MethodsFrom January 2009 to August 2018, all patients who presented within the first 48 hours of ST elevation myocardial infarction complicated by cardiogenic shock and receiving invasive management were prospectively included.ResultsThe study cohort comprised 122 consecutive patients. The mean age was 65±12 years and 74.5% of patients were males. Left ventricular failure was the most common etiology of cardiogenic shock (72.1%) and mechanical complications occurred in 8.2% of cases. Percutaneous coronary interventions were proposed for all patients and performed in a primary setting in 72.1%. A high prevalence of no reflow was noted (15.6%). Multivessel coronary artery disease was noted in 64.8% and multivessel percutaneous coronary interventions at the index procedure were performed in 22.1% of cases. Intra-aortic balloon pump was used in 17.2% of patients. The 30-day mortality was 58.2%. The only predictor of early mortality was the immediate multivessel percutaneous coronary intervention (OR=4.1, 95%CI 1.1-14.5; p=0.031).ConclusionDespite invasive management strategies, 30-day mortality of cardiogenic shock complicating ST elevation myocardial infarction remained as high as 58.2%. Immediate multivessel percutaneous coronary intervention was the only predictor of early mortality.
