CARDIAC-ANKLE VESSEL INDEX AND SHORT TERM RESULTS OF CORONARY BYPASS GRAFTING IN CORONARY HEART DISEASE

Abstract

Aim. To study the relationship of cardiac-ankle vessel index (CAVI) and the results of coronary bypass grafting in CHD. Material and methods. 356 patients after CABG were selected into two groups according to CAVI: 1st group — CAVI≥9,0 (n=231), 2nd group — CAVI<9,0 (n=125). As end points after CABG in 1 year we used death, myocardial infarction (MI), acute cerebrovascular accident (CVA), transitory ischemic attack (TIA), rhythm disorders, polyorganic dysfunction syndrome development (PDS) and combination of these. Additionally the analysis performed to analyse the influence of various pre- and perioperational factors on the development of the endpoints. Results. In patients with normal CAVI there was more prevalent one-vessel diseases and bypass to one artery, compared to those with pathological CAVI. Groups did not show a significant difference in the quantity of shunts, duration of artificial circulation, and quantity of operations. It was revealed that the presence of pathological CAVI in CHD patients does negatively influence the short-term results of the operation. In these patients there were more perioperational complications of bypass grafting including strokes and deaths (p=0,05 and 0,02, resp.) Conclusion. In CHD patients pathological CAVI was found in 35% cases of coronary bypass grafting. CHD patients with higher CAVI were older, more often they had arterial hypertension, diabetes mellitus and lesions of no coronary arterial pools. Presence of pathological CAVI was associated with higher prevalence of perioperational complications of CABG, especially deaths and strokes perioperational complications of bypass grafting including strokes and deaths (p=0,05 and 0,02, resp.)
