Clinical InvestigationThe Effects of Depression on the Course of Functional Limitations in Patients With Chronic Heart Failure
Section snippets
Design
Data were obtained from the Preventive Effect of Exercise for Management of Daily Functioning in Patients with CHF (PTMaTCH) study, a rehabilitation cohort study of CHF patients. The study protocol was registered and officially entered in the University Hospitals Medical Information Network Clinical Trials Registry system (www.umin.ac.jp, no. UMIN000000885) before the start of the study. CHF patients who underwent an inpatient rehabilitation program were recruited for the PTMaTCH study from May
Results
At the 5-month postdischarge follow-up, 254 subjects participated in the PTMaTCH study, 3 had died, 33 were rehospitalized with acute exacerbation, 1 was hospitalized for reasons other than heart failure, 3 were excluded owing to COPD, 2 were excluded owing to severe mental illness, 48 missed the PMADL-8 items at any of the 3 time points, and 16 were lost to follow-up for other reasons. Of the 254 participants, 148 successfully responded at all 3 time points (1, 3, and 5 months), and these data
Discussion
The present results indicate that depressive symptoms affect severe functional limitations in CHF patients during the recovery phase after hospital discharge. In this prospective study, the presence of depressive symptoms was an independent predictor of persistent functional limitations over a 5-month period after discharge. In contrast to most existing cross-sectional studies,31, 37, 38 our prospective study examined the recovery phase after hospital discharge. Cluster analysis revealed a
Conclusions
This study indicates that depressive symptoms are prospectively associated with severe functional limitations in CHF patients after discharge after controlling for relevant demographic and physiologic factors and physical function. Identifying clusters confirms that depressive symptoms predict the persistence of severe functional limitations and highlights their importance in the management of these patients, particularly regarding poor physical function in older patients.
