Randomized Controlled Trial Comparative Study
Low-sodium DASH diet improves diastolic function and ventricular-arterial coupling in hypertensive heart failure with preserved ejection fraction.
Heart failure with preserved ejection fraction (HFPEF) involves failure of cardiovascular reserve in multiple domains. In HFPEF animal models, dietary sodium restriction improves ventricular and vascular stiffness and function. We hypothesized that the sodium-restricted dietary approaches to stop hypertension diet (DASH/SRD) would improve left ventricular diastolic function, arterial elastance, and ventricular-arterial coupling in hypertensive HFPEF. ⋯ URL: http://www.clinicaltrials.gov.

Randomized Controlled Trial Comparative Study
Soluble concentrations of the interleukin receptor family member ST2 and β-blocker therapy in chronic heart failure.
Concentrations of soluble (s)ST2 predict prognosis in heart failure. We recently found changing doses of β-blocker (BB) may affect sST2 concentrations. It remains unclear whether sST2 concentrations identify benefit of BB therapy, however. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00351390.

Heart failure is a common Emergency Department (ED) presentation but whether ED volume influences patient outcomes is unknown. ⋯ Low-volume EDs were more likely to discharge patients with heart failure home, but low-volume ED cases exhibited worse outcomes (driven largely by readmissions or repeat ED visits). Interventions to improve management of acute heart failure are required at low-volume sites.
