[Prognostication of results of coronary artery bypass surgery in men living in the North].
We analyzed immediate and remote results of coronary artery bypass surgery and prognostication of outcome of the intervention in dependence on various risk factors in 576 men aged 29 - 71 years living in the North. We formed a model with strong prognostic effect on lethal outcome during in-hospital postoperative period which included the following parameters: perioperative myocardial infarction, complex character of surgery, left ventricular ejection fraction less than 40%, number of distal anastomoses 5 and more, functional class III chronic heart failure. Method of regression analysis revealed factors also related to lethal outcome in period of hospitalization: functional class IV of angina, duration of operation more than 5 hours, mitral insufficiency of 2nd degree and above, myocardial infarction of left ventricular anterior wall, history of 2 or more infarctions. Model with strong prognostic effect on mortality in remote period (3 years after surgery) included the following parameters: left ventricular ejection fraction less than 40%, functional class III chronic heart failure, repeat character of operation, left ventricular aneurysm, lack of use of internal mammary artery. Most significant factors additionally affecting long term mortality were the following: involvement of left coronary artery trunk, duration of surgery more than 5 hours, atherosclerosis of magistral arteries, mitral insufficiency of 2nd degree and above, cardiac rhythm disturbances.
