BACKGROUND: Heart rate (HR) at admission in patients with acute heart failure (AHF) has been shown to be an important risk marker of in-hospital mortality. However, its relation with mid and long-term prognosis as well as the impact of Ejection Fraction (EF) is unknown. Our objective was to study the relationship between long-term survival and HR at admission depending on EF in a cohort of patients hospitalized for AHF. METHODS: We analyzed the data of 2335 patients in sinus rhythm hospitalized for AHF from AHEAD registry. Patients with cardiogenic shock and AHF from surgical or non-cardiac etiology were excluded. RESULTS: Survival rates at 6 and 12 months were 84.8% and 78% respectively. Increased age, decreased diastolic BP, lack of PCI during hospitalization, increased creatinine level and increased HR (with different cut-offs according to EF categories) were found as predictors whatever the EF at 6 and 12 months. Optimal prognostic cut-offs of heart rate were identified for Heart Failure with reduced EF at 100 bpm, for Heart Failure with mid-range EF at 90 bpm and for Heart Failure with preserved EF at 80 bpm for both 6 and 12 months. CONCLUSION: Our study suggests that HR at admission appears to be an independent prognostic parameter in AHF patients in sinus rhythm irrespective of EF and can be used to classify patients according to the severity of the disease.

BACKGROUND: The role of co-morbidities in the prognosis of patients hospitalized for AHF was examined using the AHEAD (A--atrial fibrillation, H--haemoglobin<130 g/l for men and 120 g/l for women (anaemia), E--elderly (age>70years), A--abnormal renal parameters (creatinine>130 μmol/l), D--diabetes mellitus) scoring system. METHODS: AHEAD--multicentre prospective Czech registry of AHF patients; GREAT registry--international cohort of AHF patients. Data from 5846 consecutive patients hospitalized for AHF (AHEAD registry; derivation cohort) were analysed to build the AHEAD score. Each risk factor of the AHEAD score was counted as 1 point. The model was validated externally using an international cohort of similar patients in the GREAT registry (6315). RESULTS: Main outcome was one year all-cause mortality. The mean age of patients was 72±12 years, with 61.6% of patients aged >70 years; 43.4% were women. Atrial fibrillation was present in 30.7%, anaemia in 38.2%, creatinine>130 mmol/l (abnormal renal parameters) in 30.1%, and diabetes mellitus in 44.0%. The mean AHEAD score was 2.1. In patients with AHEAD scores of 0-5, the one-year mortality rates were 13.6%, 23.4%, 32.0%, 41.1%, 47.7%, and 58.2%, respectively (p<0.001), and the 90 month mortality rates were 35.1%, 57.3%, 73.5%, 84.8%, 88.0%, and 91.7%, respectively (p<0.001). CONCLUSION: The AHEAD is a simple scoring system based on the analysis of co-morbidities for the estimation of the short and long term prognosis of patients hospitalized for AHF.

BACKGROUND: Obesity is clearly associated with increased morbidity and mortality rates. However, in patients with acute heart failure (AHF), an increased BMI could represent a protective marker. Studies evaluating the "obesity paradox" on a large cohort with long-term follow-up are lacking. METHODS: Using the AHEAD database (a Czech multi-centre database of patients hospitalised due to AHF), 5057 patients were evaluated; patients with a BMI <18.5 kg/m2 were excluded. All-cause mortality was compared between groups with a BMI of 18.5-25 kg/m2 and with BMI >25 kg/m2. Data were adjusted by a propensity score for 11 parameters. RESULTS: In the balanced groups, the difference in 30-day mortality was not significant. The long-term mortality of patients with normal weight was higher than for those who were overweight/obese (HR, 1.36; 95% CI, 1.26-1.48; p<0.001)). In the balanced dataset, the pattern was similar (1.22; 1.09-1.39; p<0.001). A similar result was found in the balanced dataset of a subgroup of patients with de novo AHF (1.30; 1.11-1.52; p = 0.001), but only a trend in a balanced dataset of patients with acute decompensated heart failure. CONCLUSION: These data suggest significantly lower long-term mortality in overweight/obese patients with AHF. The results suggest that at present there is no evidence for weight reduction in overweight/obese patients with heart failure, and emphasize the importance of prevention of cardiac cachexia.
