- Health-related quality of life has been shown to impact prognosis in chronic heart failure, however with limited long-term follow-up. We analysed data spanning 8–12 years to assess the impact of health-related quality of life using the Nottingham Health Profile on first hospitalisation and mortality, for cardiovascular and all causes. Methods We included 208 patients aged ≥60 years with New York Heart Association class II–IV and left ventricular systolic dysfunction hospitalised in Stockholm during 1996–99. Data on hospital admissions, discharge diagnoses and date and cause of death were collected from administrative databases and medical records until 2007. Cox proportional hazard models were employed to analyse the time to event for mortality and hospitalisations. Results Mean age was 76 years, 58% were male and mean ejection fraction was 34%. Median survival was 4.6 years (range 6 days–11.9 years); 148 patients died. All-cause and cardiovascular mortality were determined by physical mobility (by Nottingham Health Profile), age, gender, diuretic dose and haemoglobin level. Glomerular filtration rate was significant for all-cause mortality, while atrioventricular plane displacement was predictive of cardiovascular mortality. Median time to first all-cause and cardiovascular hospitalisation was 5.7 and 11.2 months, respectively. Time to first all-cause hospitalisation was determined by physical mobility, emotional reactions, age, gender and haemoglobin level, while only physical mobility and diuretic dose predicted time to first cardiovascular hospitalisation. Conclusions In conclusion, in patients with systolic chronic heart failure, physical mobility as part of health-related quality of life is an independent prognostic marker for cardiovascular and all-cause readmissions and mortality over 12 years.

- AIM: The purpose of this study was to investigate the effects of carvedilol on diastolic function (DF) in heart failure patients with preserved left ventricular (LV) systolic function and abnormal DF. PATIENTS AND METHODS: We randomised 113 patients with diastolic heart failure (DHF) (symptomatic, with normal systolic LV function and abnormal DF) into a double blind multi-centre study. The patients received either carvedilol or matching placebo in addition to conventional treatment. After uptitration, treatment was continued for 6 months. Two-dimensional and Doppler echocardiography were used for quantification of LV function at baseline and at follow-up. Four different DF variables were evaluated by Doppler echocardiography: mitral flow E:A ratio, deceleration time (DT), isovolumic relaxation time (IVRT) and the ratio of systolic/diastolic pulmonary venous flow velocity (pv-S/D). Primary endpoint was change in the integrated quantitative assessment of all four variables during the study. RESULTS: Ninety-seven patients completed the study. A mitral flow pattern reflecting a relaxation abnormality was recorded in 95 patients. There was no effect on the primary endpoint, although a trend towards a better effect in carvedilol treated patients was noticed in patients with heart rates above 71 beats per minute. At the end of the study, there was a statistically significant improvement in E:A ratio in patients treated with carvedilol (0.72 to 0.83) vs. placebo (0.71 to 0.76), P<0.05. CONCLUSIONS: Treatment with carvedilol resulted in a significant improvement in E:A ratio in patients with heart failure due to a LV relaxation abnormality. E:A ratio was found to be the most useful variable to identify diastolic dysfunction in this patient population. This effect was observed particularly in patients with higher heart rates at baseline.
