Background and aim: Individuals with heart disease have been found to have more negative psychological and physical effects that impact their quality of life (QoL) than the general population. Spiritual well-being is considered a protective factor associated with QoL in people with heart disease. Therefore, the current research seeks to evaluate whether socio-demographic factors and spiritual well-being predict QoL among patients with heart disease.Materials and method: A total of ۵۰۰ patients who were selected through a convenient sampling method from an Iranian hospital participated in this Cross Sectional study. Data was collected using the McGill quality of life (MQOL) Questionnaire, the Spiritual Well-being Scale (SWBS), and demographic variables. The data analysis included descriptive and analytical statistics used with SPSS (v. ۲۳).Results: Following multivariate analyses, findings revealed that those participants with their main source of income derived from family or a government pension and with College or intermediate educational levels were more likely to have higher QoL. Those participants with average or poor socioeconomic status reported higher QoL than those who were more affluent. Furthermore, younger patients (-۰.۲, ۹۵% CI -۰.۳ to -۰.۰۰۳, p = ۰.۰۱۶) and those with higher social support (۰.۷, ۹۵% CI ۰.۲ to ۱.۳, p = ۰.۰۰۶) and spiritual well-being (۰.۲, ۹۵% CI ۰.۱ to ۰.۳, p < ۰.۰۰۱) had significantly better QoL.Conclusion: In the current study, spiritual well-being and social support led to reduced negative psychological sequel and improved QoL in cardiac patients.
