Greater Pain Severity Is Associated with Worse Outcomes in Patients with Heart Failure.

We examined the relationship between pain severity and outcomes in patients with heart failure with reduced ejection fraction (HFrEF) in the HF-ACTION randomized controlled trial. Trends of health-related quality of life (HRQoL) measures grouped by patients' self-reported baseline bodily pain severity were compared using correlation tests, and the association between pain severity and clinical outcomes (including a primary composite endpoint of all-cause mortality and all-cause hospitalization) was assessed using multivariable adjusted analyses. Of the 2310 patients, 22.9% reported no pain, 45.8% very mild/mild, 24.9% moderate, and 6.4% severe/very severe. Greater pain severity was associated with worse HRQoL measures (EuroQoL-5D-3L and Kansas City Cardiomyopathy Questionnaire; both p < 0.0001). Compared to those reporting no pain, patients reporting severe/very severe pain had greater risk for the primary endpoint (adjusted hazard ratio 1.42, 95% confidence interval 1.11-1.83, p = 0.01). In patients with HFrEF, greater pain severity was associated with worse HRQoL and clinical outcomes. Trial Registration: NCT00047437.
