[Characteristics and the prognosis of patients with acute heart failure in current clinical practice].
OBJECTIVE
Analysis of predefined characteristics and outcomes in a non-selected population of patients hospitalized for acute heart failure (AHF) in Slovakia.


METHODS
We conducted a nationwide prospective multicenter survey with 860 consecutive patients enrolled in 11 hospitals throughout Slovakia--two centres with a non-stop catheterization service, two central and 7 regional hospitals. Relevant data of 78 characteristics in 9 categories were collected during 3 months (between 1 May 2009 and 31 July 2009). There was a specific form designed for this survey. Collected data were then transferred into the electronic database and statistically analysed.


RESULTS
Mean age was 72 years, 81% of patients were in NYHA class III/IV (52% male). The majority of patients were admitted with decompensated heart failure (68.4%), frequency of cardiogenic shock was 0.3%. New-onset AHF (AHF de novo) was diagnosed in 31.1%, of which 20.8% was due to acute coronary syndromes. Coronary heart disease was the predominant primary aetiology of AHF (67%), followed by almost equally represented hypertension (10.5%), valvular disease (10%) and dilated cardiomyopathy (9%). Hypertension was referred as the most frequent comorbidity (82%), followed by atrial fibrillation (48%), diabetes mellitus (42%), history of renal failure (31%) and with anaemia at admission (38%). Rales were the dominant physical sign (69.9%). Systolic blood pressure greater than 140 mm Hg was present in 37.8% and QRS length > 120 ms in 21.4% of patients. Preserved left ventricular ejection fraction (> or = 40%) was observed in 57% out of 70% documented cases in the whole survey. 23.3% of patients had a history of coronary angiography. 84.3% of patients received intravenous treatment, diuretics, nitrates and inotropes were given to 82.2%, 18% and 6%, respectively. The number of patients with cardiac resynchronization therapy (CRT), with or without defibrillator function, was 0.9%. Mean length of stay was 9.2 days and in-hospital mortality was 9.1%. At discharge, 76% of patients were on angiotensin-converting enzyme inhibitors (ACE-I) or angiotensin receptor blockers (ARB), 62% were using beta-blockers (BB), however the doses of drugs were lower then recommended values.


CONCLUSIONS
Results of the survey are comparable with other observational studies, surveys and large registries. Although the percentage of patients with ACE-I/ARB and BB at discharge seems promising, there is still area for improvement in AHF patients health care.
