Ischemic heart disease is the most common cause of morbidity and mortality in elderly population. Although early mortality, morbidity and increase hospital costs are high risks for elderly patients undergoing cardiac surgery, every year proportion of elderly patients undergoing cardiac surgery has been increasing. The aim of our study was to explore the outcome including the all cause mortality after MICS CABG and sternotomy CABG in elderly patient with coronary artery disease.
This observational study includes 1126 patients, underwent coronary bypass in Staten Island University Hospital between 2005 and 2008. Patients were divided into two arms according to their ages < 75 year–old or ≥ 75 year–old. Each arm was further divided according to type of procedure into MICS CABG group or sternotomy CABG group. All patients were followed for 4 years.
Among patients ≥ 75 year–old, MICS–CABG had a significant lower 4–year all–cause mortality than sternotomy CABG (12/66=18% vs. 52/157=33%, p=0.0244), according to the two–tailed Fisher's exact test. However, the 4–year all–cause mortality rates were similar in MICS–CABG and sternotomy CABG in patients < 75 year–old, 58/572=10% vs. 32/331=10%, p=0.9, according to the two–tailed Fisher's exact test. (Figure 1) illustrates the above results.
MICS CABG has significant less long–term mortalities in elderly patients (≥ 75 year–old) than sternotomy CABG.
