Randomized Controlled TrialEffect of admission oral diuretic dose on response to continuous versus bolus intravenous diuretics in acute heart failure: an analysis from diuretic optimization strategies in acute heart failure.
Results from the DOSE-AHF study suggest that an initial continuous infusion of loop diuretics is not superior to bolus dosing with regard to clinical endpoints in acute heart failure. We hypothesized that outpatient furosemide dose was associated with congestion and poorer renal function and explored the hypothesis that a continuous infusion may be more effective in patients on higher outpatient diuretic doses. ⋯ In acute heart failure, patients on higher diuretic doses have greater disease severity and may benefit from an initial bolus strategy.

Randomized Controlled Trial Multicenter StudyThe study of LoSmapimod treatment on inflammation and InfarCtSizE (SOLSTICE): design and rationale.
The p38 mitogen-activated protein kinase (MAPK) is a nexus point in inflammation, sensing, and stimulating cytokine production and driving cell migration and death. In acute coronary syndromes, p38MAPK inhibition could stabilize ruptured atherosclerotic plaques, pacify active plaques, and improve microvascular function, thereby reducing infarct size and risk of subsequent cardiac events. The SOLSTICE trial is randomized, double-blind, placebo-controlled, parallel group, multicenter phase 2a study of 535 patients that evaluates the safety and efficacy of losmapimod (GW856553), a potent oral p38MAPK inhibitor, vs placebo in patients with non-ST-segment elevation myocardial infarction expected to undergo an invasive strategy. ⋯ The primary safety assessments are serious and nonserious adverse events, results of liver function testing, and major adverse cardiac events. Cardiac magnetic resonance imaging (N = 117) and coronary flow reserve (N = 13) substudies will assess the effects of losmapimod on infarct size, myocardial function, and coronary vasoregulation. Information gained from the SOLSTICE trial will inform further testing of this agent in larger clinical trials.

Randomized Controlled Trial Multicenter Study Comparative StudyABSORB II randomized controlled trial: a clinical evaluation to compare the safety, efficacy, and performance of the Absorb everolimus-eluting bioresorbable vascular scaffold system against the XIENCE everolimus-eluting coronary stent system in the treatment of subjects with ischemic heart disease caused by de novo native coronary artery lesions: rationale and study design.
Currently, no data are available on the direct comparison between the Absorb everolimus-eluting bioresorbable vascular scaffold (Absorb BVS) and conventional metallic drug-eluting stents. ⋯ The ABSORB II randomized controlled trial (ClinicalTrials.gov NCT01425281) is designed to compare the safety, efficacy, and performance of Absorb BVS against the XIENCE everolimus-eluting stent in the treatment of de novo native coronary artery lesions.
