BACKGROUND: 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.

TRIAL DESIGN: 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.

CONCLUSIONS: 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.
