AIMS: To assess the relationship between depression and clinical outcomes among elderly patients with heart failure (HF) in a community setting. METHODS AND RESULTS: To identify patients with HF and depression we used record linkage analysis of hospital discharge records, prescription databases and vital statistics. All consecutive patients aged>or=60 years in 6 Local Health Authorities in Italy were included. HF was defined as either: 1) hospital discharge with HF diagnosis (ICD-9: 428) and/or 2) chronic treatment for HF identified as concomitant (within 45 days) prescription of any combination of ACE inhibitors, digoxin, furosemide, bisoprolol, carvedilol, spironolactone, ARB-blockers. Depression was identified from exposure to psychotropic drugs before HF diagnosis. Cox proportional hazards models adjusted for major confounders were used. To adjust for potential residual known confounders, a propensity score analysis was performed. Sensitivity and subgroup analysis were used to demonstrate the consistency or robustness of the results. 48,117 patients with HF were identified. Of these, 3328 (6.9%) were treated for depression. Among patients with HF, those with depression were significantly older, and more likely to be women with a previous stroke. Depression significantly worsened major outcomes including all cause mortality [HR (95%CI); 1.20 (1.08-1.33)] and the composite of stroke/TIA/AMI [1.23 (1.13-1.34)]. Patients with depression had no increased risk of rehospitalisation for HF. Propensity scores and subgroup analysis confirmed these findings. CONCLUSION: Among elderly patients with HF, depression was independently associated with poor clinical outcomes mostly due to an increase in vascular events.
