Randomized Controlled Trial Multicenter Study
Cardiac structure and function in heart failure with preserved ejection fraction: baseline findings from the echocardiographic study of the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist trial.
Heart failure with preserved ejection fraction (HFpEF) is associated with substantial morbidity and mortality. Existing data on cardiac structure and function in HFpEF suggest significant heterogeneity in this population. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00094302.

Randomized Controlled Trial Multicenter Study
Long-term results of intensified, N-terminal-pro-B-type natriuretic peptide-guided versus symptom-guided treatment in elderly patients with heart failure: five-year follow-up from TIME-CHF.
Therapy guided by N-terminal-pro-B-type natriuretic peptide (NT-proBNP) levels may improve outcomes in patients with chronic heart failure (HF), especially in younger patients with reduced left ventricular ejection fraction. It remains unclear whether treatment effects persist after discontinuation of the NT-proBNP-guided treatment strategy. ⋯ URL: http://www.isrctn.org. Unique identifier: ISRCTN43596477.

Randomized Controlled Trial Multicenter Study
Prognostic effect of high-sensitive troponin T assessment in elderly patients with chronic heart failure: results from the CORONA trial.
The incremental prognostic value of high-sensitive troponin T (hs-cTnT) in heart failure (HF) beyond that of high-sensitivity C-reactive protein and amino-terminal probrain natriuretic peptide is debated. We examined the prognostic value of hs-cTnT in a subgroup of patients from the Controlled Rosuvastatin Multinational Trial in HF (CORONA) study. ⋯ URL: http://www.clinicaltrials.gov.

Randomized Controlled Trial Multicenter Study
Impact of atrial fibrillation on exercise capacity in heart failure with preserved ejection fraction: a RELAX trial ancillary study.
Atrial fibrillation (AF) is common among patients with heart failure and preserved ejection fraction (HFpEF), but its clinical profile and impact on exercise capacity remain unclear. RELAX (Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in HFpEF) was a multicenter randomized trial testing the impact of sildenafil on peak VO2 in stable outpatients with chronic HFpEF. We sought to compare clinical features and exercise capacity among patients with HFpEF who were in sinus rhythm (SR) or AF. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00763867.

Mineralocorticoid receptor antagonists improve outcomes in patients with systolic heart failure but may induce worsening of renal function (WRF) and hyperkalemia (HK). We assessed the risk factors for mineralocorticoid receptor antagonist-related WRF and for HK, as well as the association between HK and WRF with clinical outcomes in the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF). ⋯ URL: http://www.clinicaltrials.gov.
