Echocardiographic Characteristics of Cardiogenic Shock in the Cardiology Department of the Yalgado OUEDRAOGO University Hospital of Ouagadougou - Abstract
Echocardiographic data allow better management of cardiogenic shock and improved prognosis. The objectives of this study were to describe the etiologies of cardiogenic shock and their echocardiographic characteristics in the cardiac intensive care unit of the Yalgado Ouédraogo University Hospital. Methods: This was a descriptive cross-sectional study over a 6-month period from April 1, 2019, to September 30, 2019, conducted at the cardiac intensive care unit of CHU Yalgado Ouédraogo. Patients admitted for shock were systematically performed a cardiac Doppler echo using a portable vivid Q ultrasound machine, equipped with a 2-4 Mhz probe. Results: We collected 30 cases of shock, the most frequent being acute cardiac decompensation (63.33%), severe pulmonary embolism (20%) and acute coronary syndrome ST+ (10%). Cardiac echocardiography found valvular heart disease with cavitary dilatation and probably ischemic heart disease in five cases, respectively, and dilated cardiomyopathy and acute cor pulmonale in two cases, respectively. The mean LVEF was 38.56 ± 19.37% (extremes 5 and 72%). Mortality was 56.66%. In multivariate analysis, the independent predictor of death was LVEF less than 22% (OR = 37.13; CI95 [29.9-946.26], p=0.002). Conclusion: The etiologies of cardiogenic shock states are dominated by acute decompensation of pre-existing heart disease, pulmonary embolism and ST+ acute coronary syndrome. Independent predictors of mortality were LVEF <18% ((OR =4.7; CI95 [1.25-9.23], p=0.0001)), dobutamine use ((OR =2.8; CI95 [1.05-6.93], p=0.001)), and mitral stenosis ((OR =10.5; CI95 [1.65-15.20], p=0.0001)).
