Depression is common in patients with acute cardiovascular conditions and it is associated with adverse clinical events. Using the data from a nationwide, prospective registry on patients with chronic coronary syndromes (CCS), we assessed the impact of depression on major adverse cardiovascular events (MACE), a composite of all-cause death and hospitalization for myocardial infarction, revascularization, heart failure or stroke, and quality of life (QoL) at 1-year follow-up. From the 5070 consecutive CCS patients enrolled in the registry, 531 (10.5%) presented a history of depression and the remaining 4539 (89.5%) did not. At 1year (median 369; IQR 362-378days) from enrolment, the incidence of the primary composite outcome was 9.8% for patients with a history of depression and 7.2% for non-depressed patients (p=0.03). Patients with history of depression had a significantly higher rate of all-cause mortality (3.0% vs 1.4%; p=0.004) and hospital admission for heart failure (3.4% vs 1.3%; p=0.0002) compared to the group without depression. However, history of depression did not result as an independent predictor of MACE at multivariable analysis [hazard ratio 1.17, 95% confidence interval (0.87-1.58), p=0.31]. Depressed patients had worse QoL according to all domains of the EQ. 5D-5L questionnaire as compared to non-depressed patients (all p<0.001), at both enrolment and follow-up. In this contemporary, large cohort of consecutive patients with CCS, patients with a history of depression experienced a two-fold rate of mortality, a higher incidence of MACE and a worse QoL at 1-year follow-up, compared to non-depressed patients.
