Abstract
Two hundred and thirty consecutive adult patients underwent open heart surgery at
Ramathibodi Hospital from January 1, 1994 to December 31, 1995. The patients were cate-
gorised into 4 groups, A, B, C and D; consisting of 52 (22.4%) with adult congenital heart
disease, 121 (52.2%) with acquired valvular heart disease 52 (22.4%) with coronary heart disease
and 7 (3%) with diseases of the aorta(2).
The mortality in various groups were analyzed separately each year, in 1994 and 1995.
The overall mortality, in adult congenital heart disease, was 5.7 per cent consisting of acquired
valvular heart disease (6.6% ), coronary artery disease (CAD) (3.8%) and diseases of the aorta
(14.2% ). We found that the incidence of CAD and the patients underwent CABG were in-
creasing. The overall mortality for open heart surgery in adults was 6 per cent.
Though the number of patients who underwent open heart surgery did not truly repre-
sent all heart diseases, trends of coronary artery disease seem to be increasing. Risk factors of
coronary artery disease and low mortality from CABG might be the main reasons that CABG
has increased obviously.
