Left ventricular dysfunction (LV dysfunction) complicating myocardial infarction is common. Among patients with acute myocardial infarction (AMI), a strong relationship between the degree of LV dysfunction and mortality has been demonstrated. LV dysfunction is known to be a strong predictor of death in AMI with important implications for prognosis and treatment. The identification of patients at risk of developing LV dysfunction after AMI is relevant in the sense that it allows early and optimal management of heart failure for better quality of life. This prospective study of 75 cases of AMI complicated or not with LV dysfunction, hospitalized in the intensive care unit of the Mohammed V military training hospital in Rabat, covering a period of 6 months, aims to determine the predictive factors of LV dysfunction after an AMI in a Moroccan population group. It was found that male gender, delay in management, heart rate on admission, electrical territory, and the existence of crackling sounds on lungs at admission are predisposing factors for left ventricular systolic dysfunction. However, dyslipidemia is a protective factor. Early management of these patients would reduce the risk of reinfarction and death.
