Acute myocardial infarction in young adults. Analysis of risk factors and coronary angiography

Eighty patients aged under forty, survivors of an episode of acute myocardial infarction (AMI), were studied by means of angiography. Thirty five had anterior wall infarction, 26 diaphragmatic wall, 9 lateral side and 10 non Q AMI. Tobacco addiction (92% vs 71.9%) and hyperlipemia (34% vs 18.8% were higher (p less than 0.01) that in the total AMI population. They presented an average ejection fraction of 0.56 +/- 0.15 and only in three patients was under 0.30. One, 2 and 3 vessels disease respectively of 43%, 22% and 16%, similar to another series published. A 19% of patients with normal angiography coronaries was seen significantly higher (p less than 0.01) than the observed in AMI in older patients. In conclusion in spite of the good prognosis of this group of patients, is necessary to insist in primary preventive campaigns, mainly against tobacco addiction and hyperlipemia, in order to reduce the frequency of AMI in young people.
