Abstract:
BACKGROUND: Coronary artery bypass grafting (CABG) is the standard surgical treatment for coronary artery disease. Although there are many clinical reviews of the long term results after CABG in the Western countries, not many such studies have been done for Korea. Therefore, we reviewed the long term clinical results for the patients who underwent CABG at our hospital. MATERIAL AND METHOD: We retrospectively reviewed the medical records of 342 patients who underwent CABG at our hospital from February 1984 to December 2006, which is when CABG was first performed in our institution. A total of 286 patients (83.6%) were able to be followed-up, and the mean follow-up period was 75.7+/-46.1 months. RESULT: The early mortality rate was 5.6%, and late mortality rate was 23.1%. The one-year survival rate, the five-year survival rate, the ten-year survival rate and the fifteen-year survival rate were 91.5%, 82.1%, 60.7% and 50.0%, respectively. The survival rate was significantly lower for the patients over the age of 60 (p=0.002) and for those with diabetes mellitus (p=0.000), hypertension (p=0.002), multivessel disease (p=0.006) and left ventricular dysfunction (p=0.015). No significant difference was observed between the genders. Multivariate analysis showed that the statistically significant risk factors were diabetes mellitus (p=0.001), age (p=0.005) and those cases for which the left internal thoracic artery was not used (p=0.037). CONCLUSION: CABG is the effective method of treatment for coronary artery disease. Therefore, active usage of the internal thoracic artery and appropriate medical treatment after surgery, and especially for diabetes mellitus patients, are mandatory for achieving good long-term survival.
