Abstract :Objectives: The aim of the present study was to compare preoperative / postoperative ventricular functions of patients with ventricular dysfunction who were planned for coronary artery bypass grafting insert ignore into journalissuearticles values(CABG); using echocardiography and angiography, and to evaluate whether there was a significant improvement in ventricular function. Methods: This prospective study included 30 patients with poor ventricular function who had undergone CABG at the Cardiovascular Surgery Clinics of Bursa Yüksek Ihtisas Hospital. The patients` ventricular functions were compared preoperatively and postoperatively at the 2 nd , 6 th and 12 th months. Results: Of the patients, 28 were males, and the mean age was 60.1 ± 8 years insert ignore into journalissuearticles values(range 39-71);. In these cases, functional capacity improved within the early postoperative period, and global ventricular functions improved within the postoperative first year. The improvement in ejection fraction results was statistically significant at 6 months and 12 months insert ignore into journalissuearticles values( p < 0.05);. A significant decrease was observed in left ventricular enddiastolic pressures within one year insert ignore into journalissuearticles values( p < 0.001);. For the performance score, improvement was significant from the 2 nd month insert ignore into journalissuearticles values( p < 0.05);. Conclusions: Our findings show that CABG improves ventricular function in terms of EF, PS, LVEDP and NYHA classification. In conclusion, we consider that CABG is a significantly effective option in patients with poor ventricular function.
