Serum lipids and lipoproteins were estimated in 29 patients with acute myocardial infarction during acute phase (day 1,2,3), predischarge and after three months. Serum total lipids, total cholesterol (TC) and LDL-cholesterol (LDLc) showed no significant change during the hospital stay and three months followup. HDL-cholesterol (HDLc), however, started falling from day 2 onwards with statistically significant reduction at pre-discharge and remained so at 3 months. The ratios of TC/HDLc and LDLc/HDLc showed significant increase on predischarge day as compared to day 1. Serum triglycerides also showed an increasing trend after myocardial infarction with a significant increase on day 3 and predischarge as compared to day 1. it is concluded that the optimum time for assessment of serum lipid profile in patients with myocardial infarction seems to be within 24 hours of the acute episode.
