[Aorto-coronary bypass grafting in patients with pronounced left ventricular dysfunction: long-term results and value of detection of viable myocardium].
Aim of the study was to investigate effect of volume of viable myocardium as detected by stress-echocardiography on functional class and survival of patients with pronounced left ventricular dysfunction after aorto-coronary bypass grafting (ACBG). We made retrospective analysis of clinical and echocardiographic data from 216 patients with pronounced coronary pathology and left ventricular ejection fraction 35%. Stress echocardiography was carried out according to standard method in 70 patients. Mean duration of follow-up after ACBG was 2.5+/-2.3 years (from 0.4 to 9 years). Complete revascularization eliminated symptoms of angina, improved functional class of patients and was associated with high survival (5-year - 85%, 7-year - 78%). No significant effect of volume of viable myocardium on functional class and survival of patients after ACBG was revealed.
