    Abstract:
    In order to evaluate the efficacy and safety of coronary stenting, we reviewed the first 32 consecutive patients (34 vessels) who underwent elective coronary stenting during the period August 1999 to August 2000 inclusive at the Digital Lab installed at the Eric Williams Medical Sciences Complex, Trinidad and Tobago. Aspirin, heparin and ticlopidine were used routinely. Abciximab was used in selected cases (38%). The mean age of patients was 55 +/- 10 years. Eighty-one per cent were male, 52% were hypertensive and 21% were diabetic. Sixty-five per cent had severe angina. Prior Coronary Artery Bypass Grafting (CABG) was performed in 3% and previous Percutaneous Transluminal Coronary Angioplasty (PTCA) in 3%. Multivessel disease was present in 43%. The mean left ventricular ejection fraction was 53 +/- 12%. The culprit lesion was located in either the native left anterior descending (LAD) coronary artery (53%), right coronary artery (RCA) (31%), circumflex artery 13% and saphenous vein graft (3%). The mean baseline diameter stenosis was 91 +/- 9% and this was reduced to 13 +/- 33% after stenting. Procedural success was 100% for 26 partially occluded vs 50% for 8 totally occluded vessels. For the total occlusions, procedural success was inversely related to the duration of the occlusion. There were no cases of death, acute vessel closure, Q-wave myocardial infarction, repeat PTCA or emergent Coronary Artery Bypass Graft (CABG) during and following the procedure. Distal embolization occurred in one patient. The mean duration of hospital stay was one day (for 30 outpatient cases). One patient had recurrence of symptoms with a negative stress test. No patient underwent repeat angiography during the first year of follow-up. Coronary stents were successfully implanted at a tertiary care facility in the Caribbean with low in-hospital morbidity and mortality. Stents markedly reduced the diameter stenosis of the coronary lesion during PTCA. The incidence of clinical restenosis was low. Coronary revascularisation can be successfully achieved by coronary stenting in the Caribbean.
