Clinical Analysis to the Early Results of the CABG / 대한흉부외과학회지

ABSTRACT

BACKGROUND: As coronary arterial disease is increasing, we evaluated the patients who underwent CABG (Coronary Artery Bypass Grafting) and thus report the early results and risk factors related to mortality and morbidity. MATERIALS AND METHODS: Between July 1996 and February 1998, 42 patients underwent CABG. We analyzed age, sex, preoperative ejection fraction, Canadian heart classification, prevalence factors of CAD (Coronary Artery Disease), angiographic findings, graft vessel numbers, IMA (Internal Mallary Artery) use, ECC* (extracorporeal circulation) time and morbidity. We also evaluated the mortality rate and the causes of death. RESULTS: Complication was developed at 17cases. The average age of the complication group was 61+/-11.9 years and that of the noncomplication group was 51+/-10.5 years (p=0.004). ECC time was 198+/-42.5 (min) in the complication group and 158+/-47.4 (min) in the noncomplication group (p=0.008). The other factors had no correlation to the morbidity, statistically. The average follow up duration was 12.5 months and all the patients were alive except for the 2 expired cases. The mortality rate was 4.7%, among which one patient who underwent CABG with aortic valve replacement died due to multiorgan failure and the other died due to sepsis with pneumonia and wound infection. CONCLUSIONS: We conclude that the risk factors related to morbidity were age and ECC time, and that there were no correlations between other factors and morbidity.
