973-108 Unstable Angina Patients Fare No Worse than Stable Patients Ten Years After Balloon Angioplasty

Aim This study was designed to assess the 10 year clinical status of all 856 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) in the first 5 years of our experience (1980-1985) and compare those with stable (SAP) and unstable angina (UAP). Methods All patients were contacted via letter, telephone or family doctor and details of cardiac events (death, infarction, rePTCA, coronary artery surgery) checked against hospital records. Actuarial survival and event-free survival curves were constructed and SAP and UAP patients compared. Results The overall 5 and 10 year actuarial survival was 91% and 79% respectively. The 10 year event-free survival for all patients was 35%. The outcome of SAP and UAP patients are compared and displayed in the table. There is no significant difference in survival or clinical events. Conclusions Ten year survival after PTCA is good although the majority of patients suffer a further cardiac event. There is no significant long-term difference in cardiac events between SAP and UAP patients.
