OBJECTIVE: To assess health related quality of life of patients with congestive heart failure (CHF), to correlate quality of life with other functional parameters; maximal oxygen uptake (peak VO2) with submaximal tests (two minute walking test and shuttle walk test) and New York Heart Association (NYHA) with other clinical variables. METHODS: We evaluated 35 stable congestive heart failure patients (NYHA II-III). Functional status was assessed by NYHA classification, maximal oxygen uptake (peak VO2) and submaximal tests (two minute walk test and shuttle walk test). Health related quality of life was measured with short form 36 health survey (SF 36). RESULTS: NYHA functional class was correlated with social functioning of SF 36, peak VO2 and shuttle walk test. Peak VO2 was correlated with most of the parameters of SF 36. On the other hand 2 minute walk test and shuttle walk test were correlated with social functioning of SF 36. There was a correlation between peak VO2 and submaximal test, but there was no correlation between left ventricular ejection fraction, peak VO2 and NYHA class. CONCLUSION: Social functioning is impaired in patients with congestive heart failure. There is a correlation between maximal and submaximal tests. The maximal and submaximal tests can explain some degree of quality of life. Functional status can be explained with peak VO2 and shuttle walk test apart from NYHA class.
