[Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol in coronary artery disease].

The retrospective study included 250 patients, treated at Clinic for cardiovascular diseases of Tuzla Clinical center, between 30.08.2003. and 15.11.2004. In the coronary disease group there were 145 men, 55 women, with diagnosed coronary artery stenosis of 50% or more. The control group had 150 patients, 35 men and 15 women, medium age of 58.2. The control group had coronary artery stenosis of 50% or less. Coronarography was done using AXIOM ARTIS DFC (SIEMENS). Lipoproteins were determined on the Clinic for biochemistry of Tuzla Clinical Center using automatic analyser DIMENSION LxR (DADE BOEHRING). In the coronary artery disease (CAD) group elevated triglycerides were found in 38.5%, total cholesterol in 88% and LDL 55.5% of patients. The concentration of HDL cholesterol was elevated in 52.5% of patients. In the control group elevated values of triglycerides were found in 28%, total cholesterol 46%, LDL cholesterol 16%, and lower values of HDL in 10% of patients. Statistically significant differences of lipide profile of CAD patients in relation to the control group was defined. Using regresional analysis it was established that decide elevated values of total and LDL cholesterol, low values of HDL were also significant.
