Background: This post hoc analysis of the HF-ACTION cohort explores the primary and secondary results of the HF-ACTION study by etiology and severity of illness.
Methods: HF-ACTION randomized stable outpatients with reduced left ventricular (LV) function and heart failure (HF) symptoms to either supervised exercise training plus usual care or to usual care alone. The primary outcome was all-cause mortality or all-cause hospitalization; secondary outcomes included all-cause mortality, cardiovascular mortality or cardiovascular hospitalization, and cardiovascular mortality or HF hospitalization.
Background: The New York Heart Association (NYHA) functional class is a subjective estimate of a patient's functional ability based on symptoms that do not always correlate with the objective estimate of functional capacity, peak oxygen consumption (peak V(O2)). In addition, relationships between these 2 measurements have not been examined in the current medical era when patients are using beta-blockers, aldosterone antagonists, and cardiac resynchronization therapy (CRT). Using baseline data from the HF-ACTION (Heart Failure and A Controlled Trial Investigating Outcomes of Exercise TraiNing) study, we examined this relationship.

Materials And Methods: Platelet function was evaluated using standard light transmission aggregometry. Measurements of CD62P and CD40L were carried out by flow cytometry and ELISA assays.
Objectives: We sought to determine the effect of tezosentan in patients with acute decompensated heart failure (HF) associated with acute coronary syndrome (ACS).
Background: Tezosentan is a dual endothelin receptor antagonist that has been shown to improve cardiac output, decrease pulmonary capillary wedge pressure, and reduce pulmonary and systemic vascular resistance in initial clinical studies in acute decompensated HF.
Methods: The Randomized Intravenous TeZosentan (RITZ)-4 study was a multicenter, randomized, double-blinded, placebo-controlled study of tezosentan in patients with acute decompensated HF associated with ACS.
Objectives: The goal of this study was to assess the interaction between heart failure (HF) etiology and response to milrinone in decompensated HF.
Background: Etiology has prognostic and therapeutic implications in HF, but its relationship to response to inotropic therapy is unknown.
Methods: The Outcomes of a Prospective Trial of Intravenous Milrinone for Exacerbations of Chronic Heart Failure (OPTIME-CHF) study randomized 949 patients with systolic dysfunction and decompensated HF to receive 48 to 72 h of intravenous milrinone or placebo.
Context: In the Enhanced Suppression of the Platelet IIb/IIIa Receptor with Integrilin Therapy (ESPRIT) trial, treatment with eptifibatide, a platelet glycoprotein IIb/IIIa integrin blocker, was found to reduce the ischemic complications of nonurgent coronary stent implantation at 48 hours and 30 days.
Objective: To determine whether eptifibatide treatment continues to provide durable, long-term benefit after coronary stent intervention.
Design And Setting: The ESPRIT trial was a randomized, double-blind, placebo-controlled, parallel-group, crossover-permitted trial conducted from June 1999 through February 2000 at 92 tertiary care centers in the United States and Canada.
