Introduction. Evidence suggests that social support and stress may play important roles in the development and progression of heart failure, an end stage of cardiovascular disease Mookadam and Arthur, 2004 Murberg and Bru, 2001. Cohen and Wills 1985 posit that social support may influence disease through direct effects and by buffering the impact of stress on health. The present study examined 1 the main effect of functional and structural social support, independently, on markers of heart failure severity and 2 tested the stress-buffering effects of social support in persons with heart failure. Methods. One hundred forty-seven heart failure patients completed health-related questionnaires Kansas City Cardiomyopathy Questionnaire, KCCQ, performed functional assessments Six Minute Walk Test, 6MWT, and supplied a blood sample to assess a physiological biomarker -natriuretic peptide, BNP. Functional and structural social support were assessed with the Interpersonal Support Evaluation List ISEL-12 and Social Network Index SNI, respectively perceived stress was measured using the Perceived Stress Scale PSS.
