Several smaller studies have examined compliance in HF, but all were limited as they only studied either the individual components of compliance and its related factors or several aspects of compliance without studying the related factors. The aims of this study were to examine all dimensions of compliance and its related factors in one HF population. Methods and results: Data were collected in a cohort of 501 HF patients. Clinical and demographic data were assessed and patients completed questionnaires on compliance, beliefs, knowledge, and self- care behaviour. Overall compliance was 72% in this older HF population. Compliance with medication and appointment keeping was high(>90% ). In contrast, compliance with diet(83% ), fluid restriction(73% ), exercise(39% ), and weighing(35% ) was markedly lower. Compliance was related to knowledge(OR=5.67; CI 2.87- 11.19), beliefs(OR=1.78; CI 1.18- 2.69), and depressive symptoms(OR=0.53; CI 0.35- 0.78). Conclusion: Although some aspects of compliance had an acceptable level, compliance with weighing and exercise were low. In order to improve compliance, an increase of knowledge and a change of patient’ s beliefs by education and counselling are recommended. Extra attention should be paid to patients with depressive symptoms.展开更多

We related BNP and 6MWT to left ventricular ejection fraction(LVEF), New York Heart Association functional class(NYHA), and two indices of quality of life(physical subscales): the Minnesota Living with Heart Failure Questionnaire(MLwHFQph) and the RAND-36ph. Methods: Plasma BNP and 6MWT were measured at discharge in 229 patients who had been admitted for CHF. LVEF and NYHA were determined, and patients completed the MLwHFQ and RAND-36 questionnaires. Results: BNP was weakly correlated to LVEF(r=-0.29, P< 0.01) and NYHA(r=0.20, P< 0.01), but not to MLwHFQph and RAND-36ph. On the other hand, 6MWT is related to MLwHFQph(r=-0.23, P< 0.01), RAND-36ph(r=0.52, P< 0.01), and NYHA(r=-0.46, P< 0.01), but not to LVEF(r=-0.15, P=0.05). There is also no correlation between BNP and 6MWT(r=-0.01, P=0.87). Conclusions: The present data show that BNP and 6MWT represent different aspects of the clinical syndrome of CHF. The outcomes of this study suggest that BNP plasma levels are more related to cardiac function, while 6MWT reflects functional capacity and quality of life.展开更多
