A Randomised Trial of a Positive Intervention to Promote Well-Being in Cardiac Patients.

Background: Negative emotions are linked to the onset and development of coronary heart diseases (CHD), whereas positive emotions are associated with better health and lower mortality rates among patients with these diseases. The objective of this randomised trial was to improve cardiac patients' emotional states using a Programme to Improve Well-being (PIW) based exclusively on positive interventions (those that promote intentional behaviours and thoughts to improve well-being).

Methods: Cardiac patients (n = 108) were randomly assigned to two parallel groups.
