Randomized Controlled Trial
A dosing algorithm for erythropoietin alpha in older adults with heart failure and a preserved ejection fraction.
Erythropoietin stimulating agents (ESAs) is an active area of clinical investigation in heart failure (HF) but can cause hypertension and higher hemoglobin concentrations (Hb) that have been associated with adverse outcomes. We evaluated a dosing algorithm and potential confounders' effect on Hb and blood pressure (BP) in a clinical trial. ⋯ The currently employed dosing algorithm, which adjusts the administration of ESA based on the absolute hemoglobin and weekly change in hemoglobin increases Hb with relatively a low weekly dose of ESA without significant effects on BP.

Randomized Controlled Trial
Effect of levosimendan on estimated glomerular filtration rate in hospitalized patients with decompensated heart failure and renal dysfunction.
Only limited data of the long-term effect of levosimendan on renal dysfunction in patients with decompensated heart failure (DHF) have been published previously. To date, there has been no similar study carried out in a Chinese population. ⋯ A 24-h infusion with levosimendan transiently improved the renal dysfunction compared with placebo in patients with DHF, and its beneficial effects persisted for at least 14 days after the initiation of treatment.
