This study investigated the frequency of depression in individuals with cardiovascular disease, with or without an acute myocardial infarction (AMI) diagnosis, and individuals with no cardiovascular disease. It is a prospective study with 168 patients of both genders, from 35 to 65 years old, divided into three groups: 60 inpatients (diagnosed with AMI), 49 outpatients (diagnosed with cardiovascular disease without infarction), and 59 of the general population (without diagnosis of cardiovascular disease). The groups were investigated by applying questionnaires, which included the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI) and the Quality of Life Test (WHOQOL). The prevalence of depression in the AMI group was 48.3%. The variables that remained significantly associated to depression were: family history (OR=2.82 - 95%CI=1.12;7.08 - p=0.028), WHOQOL psychological domain (OR=0.93 - 95%CI=0.89;0.98 - p=0.006), and anxiety score (OR=1.08 - 95%CI=1.02;1.14 - p=0.012). These results suggest that depression disorders are not triggered post-AMI but can be present before admission to the hospital, which shows the need to investigate people with chronic coronary disease.
