IMMEDIATE AND ONE-YEAR RESULTS OF CORONAR Y-BYPASS SURGERY - RELATIONTO HYPERLIPIDEMIA

Relationship between disorders of lipid metabolism and clinical state, exercise tolerance, and frequency of graft occlusions was assessed in 178 patients In 3 months and 1 year after coronary bypass surgery. Th ere was no relation between plasma levels of lipids and lipoproteins a nd recurrences of clinical symptoms of ischemic heart disease, positiv e exercise tests and graft occlusions in immediate postoperative perio d. In 1 year after surgery occlusion rate of venous grafts increased w ith increase in total cholesterol and lipoprotein (a) levels (p<0,05). The risk of arterial graft occlusion did not depend on the presence a nd severity of dyslipidemia. These data evidenced of the necessity of correction of hypercholesterolemia and elevated lipoprotein (a) level in postoperative period for long-term maintenance of effect of coronar y artery bypass surgery.
