Clinical and angiographic profile of patients presenting with first acute myocardial infarction in a tertiary care center in northern India.

OBJECTIVE: Acute myocardial infarction (AMI) is one of the presentation of coronary artery disease (CAD) and is thought to occur in younger age group in this region. The objective of this study was to evaluate clinical, biochemical and angiographic profile of patients with first acute myocardial infarction. METHODS: Eight hundred and forty-six consecutive patients who underwent coronary angiography within 4 weeks of MI were included. RESULTS: Males (n = 705, 83.3%) outnumbered females (n = 141, 16.7%) in each age group. Mean age of presentation was lower in females (58.25 +/- 9.69: 55.74 +/- 10.63). Three hundred and forty-two (40.8%) patients were thrombolyzed. Most common type of MI was anterior wall MI (n = 485, 57.32%). Three hundred and forty (40.4%) were diabetic with females outnumbering males proportionately (females = 63, 44.68%: males = 277, 39.29%). More females were hypertensive (females = 81, 57.45%: males = 306, 43.40%). Prevalence of smoking was quite low (n = 140, 16.50%) and mean age of smokers was less by 7 years than non-smokers. One hundred and forty-two (16.7%) were obese with mean age of presentation less by 7 years than non-obese. Single vessel disease (SVD) was more prevalent (361/846; 42.67%) and was more common in younger, non-diabetics and smokers. Diabetics were more likely to have triple vessel disease (TVD) (n = 112, 32.95%). CONCLUSIONS: The study reveals that age of first AMI was comparable to that in western world. Females tend to be more hypertensive and diabetics. Younger, non-diabetics and smokers tend to have single-vessel disease. Diabetics and older population were more likely to have diffuse disease (TVD).
