RESUMO

PURPOSE: To verify the prognostic value of health-related quality of life (HRQoL) and the differences in HRQoL and clinical variables between groups of Chagas heart disease (CHD) patients with and without cardiovascular adverse events. METHODS: Seventy-five CHD patients were evaluated by echocardiography, maximal exercise testing, and Short-form of Health Survey (SF-36) Questionnaire. Patients were followed during 6 years. In the statistical analysis, uni- and multivariate Cox regression were performed to verify the accuracy of the HRQoL in predicting cardiovascular events. RESULTS: After the follow-up period (41 ± 12 months), 20 patients (27%) had adverse events. Those with poor outcome had lower left ventricular ejection fraction (LVEF) (p = 0.002), higher left ventricular end-diastolic diameter (LVDd) (p = 0.019), and worse scores in general health perceptions (p = 0.047), social role functioning (p = 0.026), and mental component summary (p = 0.043) of SF-36. Patients with lower LVEF (p = 0.003), higher LVDd (p = 0.022), worse HRQoL in the general heath perceptions domain (p = 0.022), and mental component summary (p = 0.031) were associated with worse prognosis. In the multivariate Cox regression, LVEF (HR 0.94, 95% CI from 0.90 to 0.98, p = 0.007) and mental component summary (HR 0.98, 95% CI from 0.94 to 1.00, p = 0.047) remained as independent predictors of adverse events in CHD patients. CONCLUSION: The assessment of HRQoL, especially the mental component, should be taken into account to provide an accurate prognosis in addition to other well-established predictors of poor outcomes in CHD patients.
