COMPARISON OF SERUM LIPIDS, LIPOPROTEINS AND APOLIPOPROTEINS IN PATIENTS UNDERGOING CABG WITH HEALTHY ADULTS

Abstract

OBJECTIVE:
To assess the pattern of plasma lipoproteins in CAD patients including comparison between diabetic and
non-diabetic subgroups.
METHODS:
This case control study was conducted at National Institute of Cardiovascular Diseases (NICVD) Karachi on
patients admitted for CABG from June, 2000 to June, 2001. A total of 100 patients and 100 healthy subjects
were enrolled during the study. 38 patients (38%) were diabetic with mean age of 46.16 years and 62 patients
(62%) were non-diabetic with mean age of 45.26 years. Serum lipids, apolipoproteins A, apolipoproteins B
and Lp(a) of each subject were analysed. One way ANOVA and 95% confidence interval for mean were
applied to find the association of CAD with age, BMI, glucose, cholesterol, triacylglycerols, HDL-c, LDL-c,
and Lp(a).
RESULT:
CABG patients had significantly higher blood TAG levels than controls. Similar results were observed for
HDL-c, which was significantly lower when compared with control subjects. Apo-B and Lp(a) in controls
were significantly lower than both diabetic and non-diabetic CAD patients. The level of Apo-B in diabetic
CAD was significantly higher when compared with control subjects.
