PTCA was introduced into Queen Alia Heart Institute (QAHI), Jordan, in April 1985. The objective of the study is to report the Jordanian experience with the procedure as regards success rates, clinical outcomes, and factors associated with survival following the procedure. All Jordanian patients who underwent PTCA at QAHI during the period April 1985 through December 1993, a total of 752 subjects, were followed-up to November 1st, 1998. Baseline demographic, angiographic, and clinical data were obtained from the medical records. Follow-up data were obtained from medical records as well as by telephone interviews. The Statistical Package for Social Sciences (SPSS) was used for data analysis. The Cox proportional hazard model was used to identify factors independently related to survival. Angiographic and clinical success rates were 91.5 % and 86.5 % respectively. Procedural complications occurred in 18.5 % of the subjects. There were 7 in-hospital deaths, emergency coronary artery bypass grafting (CABG) was performed for 23 patients and non-fatal myocardial infarction (MI) occurred in 53 patients before discharge from the hospital. Overall, cardiac, and event-free survival probabilities 13.5 years after PTCA were 73.6 %, 77.0 % and zero respectively. Age < 45 years and left ventricular ejection fraction (LEVF) 40 % or more were predictive of a better overall and cardiac survival. Female gender was associated with a better cardiac but not overall survival. About three fourths of PTCA-treated patients survived 13.5 years after the procedure. However, none survived event-free beyond 13.5 years.
