Quality of life in adults living in the community with previous self-reported myocardial infarction

Abstract

Aim: Quality of life (QoL) is one of the most important patient-reported outcomes in chronic diseases. Using a population-based cohort, our objective was to assess health-related QoL in individuals with a previous myocardial infarction (MI). Methods: This study was conducted on a large database representative of the adult Portuguese population aged 18 years or over, living in the community. Participants were assessed through telephone interview. A standardized questionnaire was applied to every individual about self reported chronic diseases, including previous MI. QoL was assessed with the EQ-5D-3L version of EuroQol. The prevalence of previous MI was calculated and linear regression analysis was performed. Results: The estimated prevalence of previous MI in the adult Portuguese population was 1.1%. These patients were older and more often male, had lower income and lower education levels, and were more often from urban areas. Respondents with self-reported MI assigned a lower self perception to their health status in all domains, particularly in mobility and anxiety/depression. The mean EQ-5D-3L score in patients with MI was 0.73 +/- 0.34, significantly lower than in patients without MI (0.78+0.29). Also, the number of chronic diseases was significantly higher in patients with MI (5.0 +/- 2.2 vs. 1.7 +/- 1.8). Previous MI was not independently associated with QoL, which was related to age, gender and number of comorbidities. Conclusions: Adults with previous MI have a worse self-perceived health status and QoL. Previous MI was not an independent predictor of health-related QoL after controlling for age, gender and associated chronic diseases. (C) 2020 Sociedade Portuguesa de Cardiologia.
