Left ventricular hypertrophy as a risk factor plays a major role on the results of coronary artery bypass grafting (CABG). Between February 1995 and May 1997 at Bursa Yüksek İhtisas Hospital we performed CABG at a hypertrophic ggroup of 20 patients who had left ventricular hypertrophy and a control group of 20 patients who had no left ventricular hypertrophy in order to see the effect of left ventricular hypertrophy on early results of CABG. We compared preoperative, operative, and postoperative variables of the patients.

The hypertrophic group which was calssified for the left ventricular mass index as regarded hypertrophy and control group which had no hypertrophy had the same characteristics for the preoperative variables and operative techniques.

Left ventricular hypertrophy had the important effects from different directions on the early period of the operative results. Because of the limited number of the patients and only one mortality in the hypertrophic group we did not observe significantly difference between the results (p=0.5) but, on postoperative period, there are higher incidence of arrhythmia (p=0.028) and more inotropic support need (p=0.021) in the hypertrophic group.

The hypertrophic group had significantly longer intensive care unit stay (p=0.001). When we looked at the other morbid events, especially low cardiac output syndrome (p=0.17), perioperative MI (p=0.5), infection (p=0.5), and IABP insertion (p=0.5) in the hypertrophic group were higher proportion than the control group but no statistically significant.

We conclude that left ventricular hypertrophy as a risk factor had negative effects on the early results of CABG.
