Heart failure may bring about positive outcomes, which have not been adequately addressed in the literature. Therefore, this qualitative study sought to scrutinize the experiences of patients and the perceived positive effects of heart failure. The opinions of 19 patients with heart failure in Mashhad city (Iran) were collected via semistructured interviews from December 2017 to November 2018. After analyzing the data, six themes were identified by framework analysis: healthy lifestyle, effective interactions, appreciation of life, spirituality, reappraisal of life and priorities, and endurance. Such positive effects may lead to empowerment and better coping of patients with the disease. Therefore, nurses should consider the patients' perception of illness in addition to the disease manifestations and offer training focusing on the possibilities instead of limitations.
