CABG IN CHRONIC STABLE ANGINA-PECTORIS PATIENTS - INDICATIONS AND OUTCOMES (SECOR SBU)/

Objective: In order to ascertain the reasons why coronary revascularis ation is performed, the appropriateness of these procedures and their outcomes, a national collaborative study encompassing 7 of 8 hospitals performing CABG in Sweden was undertaken. This article presents the i ndications and outcomes in the largest intervention group, chronic sta ble angina pectoris treated by first time CABG. Methods: A prospective multi-centre study was carried out during a 3.5 month period in each centre. Patients (1039) with chronic stable angina pectoris undergoing first time CABG were enrolled. Patients' quality of life was recorded al the time they underwent angiography and again 6 months post-operat ively. Mortality and serious peri-and post-operative complications wer e recorded. ?he study was designed and carried out by an independent g overnment agency, the Swedish Council for Technology Assessment in Hea lth Care (SBU) with a project group of representatives for the Swedish Societies for Cardiology: Thoracic Radiology and Thoracic Surgery. Re sults: Median age was 66 years. A total of 80% were males. The mortali ty rates at 30 days and 6 months were 1.0 and 1.9%, respectively. A ba lloon pump was used for 0.9% of patients and 1.4% of them were on a re spirator for more than 24 h. At recruitment, 43.9% of the patients rep orted having severe angina (CCS III/IV), 70.1% had angina greater than or equal to 3 times per week, and 53.1% used sublingual nitrates grea ter than or equal to 3 times per week. The corresponding results at 6 months were 6.7, 10.5 and 3.3%. respectively. Patient satisfaction wit h operative treatment was high. In comparison with the pre-operative s tatus, quality of life was markedly improved after surgery. Conclusion : This study shows that CABG in chronic stable angina pectoris yields good outcomes with a low mortality and morbidity and a high degree of patient satisfaction and quality of life.
