Health related quality of life of patients undergoing oral anticoagulation therapy.

This is a descriptive cross-sectional study, which aimed to analyze the health related quality of life (HRQoL) and its relationship with gender, age, duration and indication for the use of oral anticoagulants. A total of 178 patients were interviewed and the HRQoL was assessed through eight domains of the SF-36. The descriptive statistics used were, the Student's t, ANOVA and Tukey's tests for the comparison of the means between the groups. The indication for use was predominantly the metallic prosthetic heart valve (50%) with warfarin the most widely prescribed anticoagulant (83.3%). The means of the domains of the SF-36 ranged from 82 (Social aspects) to 54.8 (Physical aspects). Women, elderly, patients diagnosed with atrial fibrillation and with less than one year of medication use, presented a worse HRQoL evaluation. The results obtained can guide nursing actions, in that they indicate possible associations between the HRQoL and the sociodemographic and clinical variables of the patients.
