Evaluation of hyperlipidemia in patients candidates for coronary artery bypass graft surgery

The aim of this study was to evaluate the relationship between hyperlipidemia and serum levels of blood lipids and the number of coronary arteries involved in patients undergoing coronary artery bypass grafting. Study design: This is a cross-sectional descriptive study that was performed in 30 years in 2018-2020 in Shahid Madani Hospital (Tabriz University of Medical Sciences) with the participation of patients candidates for coronary artery bypass graft surgery and their fat profile was examined by the number of involved vessels. In the study of 150 patients with coronary artery disease, candidates for CABG surgery, patients were divided into three groups based on the number of vessels involved in angiography, and it was observed that 4 patients (2.7%) had single involvement. Vascular, 39 patients (26%) have 32 vascular involvement and 107 patients (71.3%) have vascular involvement. A total of 64 patients (42.7%) were female and 86 patients (57.3%) were male and the mean age was 58.2 ±10.86 years. Serum fat levels were assessed by the number of coronary arteries involved. Total cholesterol and LDL are important indicators for predicting the extent of coronary artery involvement. While the prevalence of elevated total cholesterol and elevated LDL are associated with multivascular involvement, the role of elevated LDL in multivessel coronary artery involvement is more effective than increased total cholesterol. Total cholesterol and LDL are among the predictors of the potential need for surgical intervention.
