Randomized Controlled TrialAdaptive servo-ventilation in cardiac function and neurohormonal status in patients with heart failure and central sleep apnea nonresponsive to continuous positive airway pressure.
The aim of this study was to investigate whether effective suppression of central sleep apnea (CSA) by adaptive servo-ventilation (ASV) improves underlying cardiac dysfunction among patients with heart failure (HF) in whom CSA was not effectively suppressed by continuous positive airway pressure (CPAP). ⋯ Patients with HF and unsuppressed CSA despite receiving CPAP may receive additional benefit by having CPAP replaced with ASV. Additionally, effective suppression of CSA may improve cardiac function in HF patients.

Randomized Controlled Trial Multicenter Study Comparative StudyCost-effectiveness of N-terminal pro-B-type natriuretic-guided therapy in elderly heart failure patients: results from TIME-CHF (Trial of Intensified versus Standard Medical Therapy in Elderly Patients with Congestive Heart Failure).
This study aimed to assess cost-effectiveness of N-terminal pro-B-type natriuretic peptide (NT-proBNP)-guided versus symptom-guided therapy in heart failure (HF) patients ≥60 years old. ⋯ NT-proBNP-guided therapy has a high probability of being cost effective in HF patients with reduced LVEF, particularly in patients age 60 to 75 years or with less than 2 comorbidities. (Trial of Intensified versus standard Medical therapy in Elderly patients with Congestive Heart Failure [TIME-CHF]; ISRCTN43596477).
