[Risk factors and clinical aspects of myocardial infarction in patients younger than 40 years in the Point G Teaching Hospital].

A retrospective and analytical study was conducted, over 9 years, from January 2004 to December 2012. It included 10 inpatients and took place at the cardiology service of the Point G teaching hospital. Its goals were to assess cardiovascular risk factors, the delay between the clinical onset and admission and to describe ECG changes and echocardiographic changes of myocardial infarction in patients under 40 year-old. Young patients accounted for 6.8% of MI admissions with a male predominance of 90%. The disease frequency has increased with age, 40% were within 38-40 year-old range, the risk factors were predominantly smoking 80%, Stress 50%, High Blood Pressure 40% and dyslipidemia 20%. Typical chest pain was the most common recorded symptom. Anterior necrosis was the most common of electrical pattern, 8 out 10 times the ejection fraction was down and segmental kinetic was impaired in 60% of patients on echocardiography. Over 3 quarters of patients were admitted 12 hours after the onset of symptoms and the evolution during hospitalization was good with no fatality.
