Therapeutic control and quality of life in coronary artery bypass surgery patients

BACKGROUND: Description of measures of secondary prevention and of health related quality of life one year after the intervention in patients undergoing coronary artery bypass surgery. PATIENTS AND METHOD: One year follow up prospective study in patients undergoing first coronay bypass surgery without associated procedures and aged less than 80 in public and private hospitals in Cataluna, Spain. RESULTS: 710 patients were included, 85.4% were men, and mean age was of 63 years. When compared women and men, 74.8 vs 48.7% patients were diagnosed of hypertension, 70.2 vs 55% of hypercholesterolemia, and 42.3 vs 28.7% of diabetes (p < 0.01); on the other hand, 31.2% of men and 2.9% of women were active smokers (p < 0.01). After a year of follow-up, 7% of the total population remained smokers; a significant reduction of anti-anginal treatments and a significant improvement in health related quality of life were observed. Cholesterol lowering treatment in patients previously diagnosed of hypercholesterolemia increased significantly between hospital admission and one year after hospital discharged (from 44% at the beginning to a 58% at the year of follow up; p < 0.01). CONCLUSIONS: Patients undergoing coronary artery bypass surgery clinically improved one year after the intervention, improving also their health related quality of life. However, the percentage of smokers and the level of antihipertensive and lowering cholesterol treatment at the end of follow up suggest a suboptimal control of risk factors in high risk patients.
