Influence of depression trajectories in heart failure patients with preserved ejection fractions: a secondary analysis of adverse outcomes in the TOPCAT trial
Abstract
Background Long-term patterns of depressive symptoms among patients with heart failure, specifically those with a preserved ejection fraction (HFpEF), and their relationship with prognoses are not well studied. Methods This analysis included 609 participants from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) trial. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) at baseline and at 1-year, 2-year and 3-year intervals. Individual trajectory patterns based on PHQ-9 scores during the first 3 years were identified using latent class trajectory models, and their associations with clinical outcomes were evaluated using Cox regression models. Results Among the 609 participants, 316 (51.9%) were female, with a median age of 74 years (IQR: 66, 80). Four distinct depression trajectory patterns were identified: low (consistently low scores; 349, 57.3%), mild (sustained mild elevation; 110, 18.1%), high (sustained moderate–severe elevation; 52, 8.5%) and recurrent deterioration (high baseline scores, remission, then escalation; 98, 16.1%). According to the multivariate Cox model, recurrent deterioration was associated with a significantly greater risk of all-cause mortality (HR: 2.05; 95% CI 1.16, 3.64) than the low trajectory pattern. No significant differences were found among the low, mild and high trajectory groups. Conclusions Four distinct depression trajectory patterns were identified among…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 609 participants or records.
