Heart failure (HF) is an increasingly prevalent condition contributing to significant morbidity and mortality among African-Americans. The Heart Failure Adherence and Retention Trial (HART) is the largest NHLBI funded behavioral clinical trial of patients with HF (R01 HL65547). The HART trial has recruited approximately 40% minority participants, with 33% being African-American. The purpose of this qualitative study is to conduct an in-depth examination of the subjective experience of African-American participants in the intervention arm of the HART. Five focus groups were conducted with a total of 25 participants. The mean age of those attending was 55 years, with a range between 39 and 82 years, 52% of the participants were female, and 92% were African-American. Participants gained overall general medical knowledge about HF and how HF influenced their own lives. Participants appeared not only to understand the self-management skills that were taught; but also how to apply them. They also demonstrated understanding of the connection between lifestyle and HF. Factors that may promote retention include mutual support, the opportunity to engage in meaningful social activity, and feeling cared for. Factors that may limit retention include anxiety and denial about HF and logistical and emotional barriers to attending groups. Factors with unclear effects on retention include remuneration, ethnicity of the group leader, and the role of religious or spiritual content in meetings. While a number of perceived benefits exist to group participation, there are significant and logistical barriers to retention. Ongoing attention to cultural sensitivity is a likely factor in successful retention of study participants.
