title: [Prevalence and influence of risk factors on coronary shunting operations in patients with aterosclerosis of abdominal aorta and peripheral vessels].
abstract: Retrospective study analysis concerning the prevalence of risk factors for unfavorable outcomes after coronary operations in patients with peripheral arterial atherosclerosis is presented. Meta-analysis of individual risk factors was carried out. Frequency of complications after coronary shunting in patients with various concomitant diseases is evaluated. The multifactorial relative risk affecting hospital lethality is defined. The study includes 131 patients with generalized atherosclerosis, which have underwent myocardial revascularization at the first stage (the main group) and at the second stage have been operated on abdominal aorta and peripheral arteries. 1128 patients without peripheral arterial atherosclerosis have made the control group. They underwent only coronary shunting. All patients were treated from December of 1994 till June of 2006. Relying on the results of the study cumulative relative risk for unfavorable outcomes after revascularization is 1.8 times higher in patients from the main group than in patients from the control group, and the risk for primary complications is 2.03 times higher. Concomitant atherosclerotic arterial involvement among cardiosurgical patients is associated with high risk for stroke in postoperative period. In case of chronic renal failure risk factors are cumulated. In the main group lethality made 5% , which was higher as compared with the control group. Correlation of such risk factors as heart failure and renal failure (creatinine level more than 1.8 mg/dl) with lethality has been revealed among patients from the main group. Lethality risk raises in 5.30 times in the presence of heart failure in medical history, and raises in 13.15 times in case of initially elevated creatinine level. Age of patient didn't have any influence on lethality in early postoperative period.
