Numerous studies have shown that social support improves health behaviors in patients with coronary artery disease (CAD). The purpose of this study was to examine the relationship between adherence to a healthy lifestyle, and social support and selected sociodemographics among patients with CAD. Cross-sectional descriptive design was used. A convenient sample of 153 patients with CAD was recruited from the cardiac clinic in an educational hospital in the north of Jordan. One hundred and thirty-three patients completed the interview. Social support was the most significant predictor—t(124) = 9.51, p < .001—which explained 60% of variance in adherence to a healthy lifestyle. Providing patients with adequate social support improves adherence to a healthy lifestyle. More attention should be given to the elderly and patients with low income to enhance adherence to a healthy lifestyle. The applications of this study in practice provide a guide for nursing clinical assessment of social support for patients facing CAD.
