The Heart Failure Adherence and Retention Trial (HART): design and rationale.

ABSTRACT: Heart failure (HF) is increasing in prevalence and is associated with prolonged morbidity, repeat hospitalizations, and high costs. Drug therapies and lifestyle changes can reduce hospitalizations, but nonadherence is high, ranging from 30% to 80%. There is an urgent need to identify cost-effective ways to improve adherence and reduce hospitalizations.The Heart Failure Adherence and Retention Trial (HART) evaluated the benefit of patient self-management (SM) skills training in combination with HF education, over HF education alone, on the composite end points of death/HF hospitalizations and death/all-cause hospitalizations in patients with mild to moderate systolic or diastolic dysfunction. Secondary end points included progression of HF, quality of life, adherence to drug and lifestyle regimens, and psychosocial function. The HART cohort was composed of 902 patients including 47% women, 40% minorities, and 23% with diastolic dysfunction. After a baseline examination, patients were randomized to SM or education control, received 18 treatment contacts over 1 year, annual follow-ups, and 3-month phone calls to assess primary end points. Self-management treatment was conducted in small groups and aimed to activate the patient to implement HF education through training in problem-solving and 5 SM skills. The education control received HF education in the mail followed by a phone call to check comprehension.The significance of HART lies in its ability to determine the clinical value of activating the patient to collaborate in his or her care. Support for the trial hypotheses would encourage interdisciplinary HF treatment, drawing on an evidence base not only from medicine but also from behavioral medicine.

Project description:The rationale and design of the Surgical Treatment for Ischemic Heart Failure trial is described. Before the Surgical Treatment for Ischemic Heart Failure trial, less than 1000 patients with ischemic cardiomyopathy had been studied in randomized comparisons of medical therapy versus coronary artery bypass grafting. Trial data reflect how these therapies were delivered more than 20 years ago and do not indicate the relative benefits of medical therapy versus coronary artery bypass grafting in contemporary practice.Randomization of consenting patients with heart failure, left ventricular ejection fraction of 0.35 or less, and coronary artery disease is based on whether patients are judged by attending physicians to be candidates only for coronary artery bypass grafting or can be treated with medical therapy without coronary artery bypass grafting. Patients eligible for surgical ventricular reconstruction because of significant anterior wall akinesis or dyskinesis but ineligible for medical therapy are randomly assigned to coronary artery bypass grafting with or without surgical ventricular reconstruction. Patients eligible for medical therapy are randomly assigned between medical therapy only and medical therapy with coronary artery bypass grafting. Patients eligible for all 3 are randomly assigned evenly to medical therapy only, medical therapy and coronary artery bypass grafting, or medical therapy and coronary artery bypass grafting and surgical ventricular reconstruction. Major substudies will examine quality of life, cost-effectiveness, changes in left ventricular volumes, effect of myocardial viability, selected biomarkers, and selected polymorphisms on treatment differences.Enrollment is now complete in both STICH hypotheses. Follow-up will continue until sufficient end points are available to address both hypotheses with at least 90% power. The primary outcome of hypothesis 2 is expected to be reported in 2009. The primary outcome of hypothesis 1 is expected to be reported in 2011.The Surgical Treatment for Ischemic Heart Failure trial is a National Heart, Lung, and Blood Institute-funded multicenter international randomized trial addressing 2 specific primary hypotheses: (1) coronary artery bypass grafting with intensive medical therapy improves long-term survival compared with survival with medical therapy alone, and (2) in patients with anterior left ventricular dysfunction, surgical ventricular reconstruction to a more normal left ventricular size plus coronary artery bypass grafting improves survival free of subsequent hospitalization for cardiac cause when compared with that with coronary artery bypass grafting alone.
