title: Serum levels of lipoprotein (a) and other lipids in angiographically defined coronary artery disease patients and healthy blood bank donors.
abstract: Lipoprotein (a) (Lp(a)) and other lipid values have been correlated with angiographically defined [table: see text] coronary artery disease. To study this relationship in Indian patients, plasma levels of Lipoprotein (a) and other lipids were assessed in 74 patients undergoing Coronary arteriography and also in 53 age and sex matched healthy male blood bank donors who served as controls. Total cholesterol (mg/dl) (211 +/- 56 vs 186 +/- 43; p < 0.001), low density lipoprotein Cholesterol (mg/dl) (117 +/- 40 vs 88 +/- 29; p > 0.001) and low density lipoprotein/high density lipoprotein cholesterol ratio (2.6 +/- 0.8 vs 2.2 +/- 0.9; p < .001) were significantly higher in patients than controls. High density lipoprotein-cholesterol (mg/dl) (43.5 +/- 6 vs 42.1 +/- 7; p-ns) very low density lipoprotein-cholesterol (mg/dl) (49.7 +/- 17 vs 56.1 +/- 25; p-ns) and triglycerides (mg/dl) (155 +/- 101 vs 167 +/- 88; p-ns) were not statistically different in two groups. Lipoprotein (a) levels showed highly skewed distribution. Patients (n = 74) showed almost five fold higher lipoprotein (a) levels (mg/dl) as compared to controls (n = 53) [105 +/- 565 vs 23 +/- 76]. Patients with very high lipoprotein (a) levels [values of more than 40 mg/dl] (n = 18) had high density lipoprotein cholesterol and total cholesterol significantly lower than rest of the patient group. [high density lipoprotein cholesterol (mg/dl) 41.00 +/- 3.7 vs 44 +/- 6.4; p < 0.01 and total cholesterol (mg/dl) 192 +/- 34 vs 217 +/- 53; p < 0.05].
