ABSTRACT
The study is a retrospective review of the demographic, clinical, angiographic, and operative data of the first 205 consecutive CABG operations performed by Caribbean Heart Care at the Eric Williams Medical Sciences Complex (EWMSC), Trinidad and Tobago, between November 1993 and December 1997. The aim of the study was to determine the in hospital and intermediate term follow up results. The mean age of patients was 59 ñ 10 years and 78 percent male. Sixty-four percent were of East Indian descent, whereas, 16 percnt were of Africian descent. Forty-eight percent of the patients were hypertensive, 46 percent were diabetic, 33 percent had hyperlipidaemia, 20 percent had a recent history of cigarette smoking and 16 percent were obese. Sixty-five percent had a positive family history of ischaemic heart disease. The average time interval between angiography and surgery was 2.3 months. At the time of angiography, 63.5 percent of patients had Canadian Cardiac Society (CCS) class 3 or 4 angina. The mean ejection fraction was 61 ñ 15 percent. Wall motion abnormalities were seen in 67 pecent of patients. Significant stenoses of the left anterior descending artery, right circumflex artery, circumflex and ramus coronary arteries were present in 91 percent, 78 percent, 54 percent and 5 percent, respectively. Many patients (67 percent) had severe diffuse disease on angiography. The mean intensive care stay was 2.2 ñ 0.8 days. In hospital mortality was 3.9 percent (8/205). THe most frequent post operative complicaton was haemorrhage (2.6 percent). Acute renal failure occurred in 2.1 percent; pulmonary collapse, 1.6 percent; 1 percent and cardiac arrest , 1 percent. Both sternal wound infections and systemic sepsis occurred in 0.5 percent. Intermediate term follow-up data were obtained for 92 percent (189/205). The duration of follow-up ranged from 1 to 5 years (mean 3.7 years). During the follow up period, 7 patients (3.4 percent) died. Angina severity was reduced from a mean CCS score of 2.61 ñ 0.95 before CABG ot 1.22 ñ 0.55 at the time of follow up (p<0.0001). Overall 4-year mortality compared favourably with data from international studies. Among survivors, quality of life improved as evidenced by the reduction in the mean angina score.(Au)
