Calidad de vida 2 años después de la revascularización coronaria

Abstract

Objective. To determine the impact of coronary revascularization surgery on patients’ quality of life and to identify the presence of lifestyles representing a risk for coronary heart disease. Method. We performed a longitudinal prospective study of 150 consecutive patients who underwent coronary surgery over a 6-month period. Perceived quality of life was evaluated before the intervention, at 6 months (n = 132) and 2 years later (n = 119). As measurement instruments, the MOS Health Survey (SF-36), the Nottingham Health Profile (NHP) and a questionnaire to identify lifestyles were used. Results. Most of the patients (95.8%) were men and were aged more than 50 years old (80.7%). Before surgery, significant physical limitations were present in 39.5%, comorbidity in 79%, prior infarction in 8.7% and three-vessel disease in 68%. The mean length of hospital stay was _ days in 88.2% of the patients. The health benefits were greater at 6 months after the intervention than at 2 years, with better perceived quality of life in all dimensions of the instruments used to assess quality of life (p< 0.001). Comorbidity, the number of risk factors and postoperative complications showed no influence on quality of life 6 months after surgery. Two years after the intervention, 33.6% of the patients resumed their professional activity and most adopted healthier lifestyles. Conclusions. Coronary revascularization substantially improves patients’ quality of life, providing health benefits 2 years after the intervention.
