PREVENTIVE MYOCARDIAL REVASCULARISATION BEFORE ABDOMINAL AORTIC INTERVENTIONS: LONG-TERM RESULTS

Abstract

Aim. To assess the effects of preventive myocardial revascularisation on the longterm results of abdominal aortic interventions. Material and methods. The retrospective analysis of the data from patients examined before planned abdominal aortic interventions was performed. Group I included 86 patients (mean age 59,4±7,7 years) who were operated at the Kemerovo Cardiology Centre clinic. Group II included 32 patients (mean age 53,5±6,2 years) who were operated at the NovokuznetskCityClinical Hospital No. 29. Before abdominal aortic interventions, the majority of Group I patients underwent coronary angiography (CAG) and, if indicated, preventive myocardial revascularisation. The long-term results were assessed 4–6 years later. Results. In Group I, CAG was performed in 77 (89%) patients, and preventive myocardial revascularisation was performed in 23 (27%) patients. Among Group I patients, fatality was 1,2% (n=1) in the long-term post-intervention period, with the level of total mortality of 3,5%. In Group II patients, the respective figures were 31,2% (n=10) and 34,4% (p<0,001). In univariate analyses, the main predictor of total morality was the absence of preventive myocardial revascularisation (odds ratio, OR, 14,49; 95% confidence interval (CI) 3,65–57,49; p<0,001). Clinical manifestations of angina (p=0,063) and myocardial infarction in medical history (p=0,105) failed to demonstrate statistical significance as mortality predictors. The factors associated with a reduction in the risk of fatal outcomes were
