Impact of depression and/or anxiety on the presentation of cardiovascular events in a cohort with metabolic syndrome. StreX project: Five years of follow-up.

Abstract

To determine the role of anxiety and depression on the incidence of cardiovascular events (CVE) in a Catalonian population with metabolic syndrome (MetS) over a five-year follow-up according to the number/type of MetS criteria. Prospective study to determine the incidence of CVE according to the presence of anxiety and depression disorders among individuals with different combinations of clinical traits of the MetS. Primary Care, Catalonia (Spain). 35-75 years old fulfilling MetS criteria without CVE at the initiation of follow-up (2009). We studied 16 MetS phenotypes [NCEP-ATPIII criteria] based on the presence of depression/anxiety. The primary endpoint was the incidence of CVE at five years. We analyzed 401,743 people with MetS (17.2% of the population); 8.7% had depression, 16.0% anxiety and 3.8% both. 14.5% consumed antidepressants and 20.8% tranquilizers. At the 5-year follow-up, the incidence of CVE was 5.5%, being 6.4% in men and 4.4% in women. On comparing individuals with and without depression the incidence of CVE was 6.7% vs. 5.3%, respectively (p<0.01), being 5.5% in both groups in relation to anxiety. Depression and anxiety play a role in the poor prognosis of patients with MetS. In Catalonia, the two predominant MetS phenotypes do not include obesity as a criterion.
