Cardiovascular Function and Risk Factors

Describe the clinical characteristics and identify potential risk factors for in-hospital lethality in patients with decompensated heart failure admitted to an intensive care unit.Decompensated heart failure patients consecutively admitted to an intensive care unit between June 2001 and December 2003 were selected and followed during hospitalization until discharge or death. Clinical characteristics at admission were recorded and evaluated as independent risk predictors for in-hospital mortality by multiple logistic regression analysis.A total of 299 patients (69+/-13 years of age and 54% men) were enrolled. Coronary artery disease was the main cause of heart failure in 49% of the cases. Diabetes mellitus and systemic arterial hypertension occurred in 37.5% and 78% of the patients, respectively. At admission, 22% of them had atrial fibrillation, 21.5% had renal dysfunction, and 48% anemia (16.5% with severe anemia). Severe systolic dysfunction (left ventricular ejection fraction 70 years, and hyponatremia were independently associated with in-hospital mortality.Patients admitted to an intensive care unit due to decompensated heart failure have high in-hospital lethality. In this study, variables recorded at admission, such as previous stroke, atrial fibrillation, hyponatremia, renal failure, and age > 70 years were predictors of in-hospital lethality.
