0286 : Predictive factors of cardiogenic shock in acute phase of acute coronary syndrome: prospective study

Abstract

Cardiogenic shock is usually considered a sequel of ST-segment elevation myocardial infarction. This study assessed the incidence and Predictive factors of cardiogenic shock developing after enrollment among patients with and without ST-segment elevation. Among 198 patients who did not present with cardiogenic shock, 80 (40%) had and 100 (50%) did not have ST-segment elevation on the enrollment ECG. Cardiogenic shock developed in 7.2% Of ST-segment elevation patients compared with 5.5% of patients without ST-segment. Shock developed significantly later among patients without ST-segment elevation. The main cause of cardiogenic shock was primitive in connection with impaired LV systolic function, followed by a severe ventricular arrhythmia. Vasopressor therapy was prescribed in 85.7% of patients. A systolic electro drive probe was placed in 28%. An external shock was performed in 28%. The hospital mortality was 40%. Independent predictors of cardiogenic shock occurred are the extended territory VD (p < 0.004) ; the biventricular dysfunction (p < 0.002), severe ischemic mitral regurgitation (p < 0.003), high blood glucose (p <0.005), elevated troponins (p < 0.004), and TIMI flow < 2 (p < 0, 0001). Cardiogenic shock occurs in the setting of acute ischemic syndromes remains a therapeutic challenge. Patient characteristics, timing, clinical course, echocardiographic and angiographic findings differ between the 2 groups. The author hereby declares no conflict of interest
