title: Prognostic significance of risk factors in acute myocardial infarction in young.
abstract: The study included 45 consecutive patients in the age group of 27 to 39 years presenting with AMI diagnosed by typical history, ECG changes and enzyme response. Prognostic significance of various risk factors in AMI in young was evaluated. There were 41 M (91.1%) and 4 F (8.9%) with mean age of 34.6 years. ECG showed anterior myocardial infarction (MI) in 18 (40%), inferior MI in 15(33.3%), Subendocardial inf in 10(22.5%) and combined anterior and inferior MI in 2 (4.5%) cases. Various risk factors were: Smoking (60%), hyperlipidemia (44.4%), stress (40%), hypertension (28.9%), family history (28.9%), diabetes mellitus (15.7%) and obesity (8.8%). Attention was given on atherogenic index (AI) (22.2%). Coronary angiogram was done in 20, which revealed significant coronary arterial obstruction in 15 cases; 3-vessel disease (n = 7), 2 vessel disease (n = 4) and single vessel disease (n = 4). Both 3 VD and 2 VD were associated with high AI. Risk factors (RF) were grouped as RFGI when combination of 3 or more RF were present, and RFG II when 2 or less RF were present. RFGI and RFGII were present in 40% and 60% cases respectively. Prognostically, patients were divided in two groups of MI-fatal (6) and nonfatal (39), the latter were subdivided into complicated (14) and uncomplicated (25). It was observed that more fatal cases were found in RFGI, whereas nonfatal uncomplicated MI was more in RFG II (P less than .001).
