Abstract
Objective. To quantify the adverse influence of depression and anxiety assessed at the time of myocardial infarction, on the quality of life 5 years after the infarction. Methods. The Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI) were completed in a group of 196 patients admitted in the hospital following non-fatal myocardial infarction, and the SF-12 quality of life questionnaire was administered during the 5- year follow-up. Results. Regression analysis showed a strong association between baseline depression and QoL in both the physical and mental domains; the higher the depression scores, the poorer the QoL. However, anxiety present at the time of myocardial infarction did not predict later QoL. Conclusions. Depression but not anxiety following MI predicts longer-term quality of life in myocardial infarction survivors.
