Calidad de vida y adherencia al tratamiento en pacientes sometidos a Bypass coronario

Background: The bypass coronary surgery allows to place a blood vessel graft as a bridge to replace the occluded artery, with this the blood flow distribution will be restored to the cardiac muscle. In Ecuador, cardiovascular diseases are the leading cause of death. Therefore, understanding the quality of life and treatment adherence of these patients is essential for accurate assessment. The Coronary Revascularisation Outcome Questionnaire (CROQ) is a tool created to evaluate the quality of life in these patients. Objective: To evaluate and analyze the quality of life and adherence to treatment in patients undergoing bypass surgery. Methods: In this descriptive, observational, and cross-sectional study, the CROQ was translated into Spanish and used alongside the Simplified Medication Adherence Questionnaire (SMAQ) to assess both quality of life and treatment adherence. A total of 83 patients who underwent coronary bypass surgery were evaluated at hospitals in Guayaquil, Ecuador. In terms of statistical analyses, internal consistency, acceptability, reliability, correlations and descriptive statistics were made. Results: Reliability coefficients greater than 0.70 were obtained, indicating a favorable outcome. Acceptability levels were also satisfactory, being greater than 0.20. Furthermore, with a p-value of <0.05, the results were deemed statistically significant. Conclusions: The Spanish version developed in this study is valid and can be used to assess the quality of life of these patients.
