ABSTRACT
Introduction and Objectives: Heart failure is a major cause of admission to intensive care units. The objective of this research was to describe the behavior of acute heart failure in the Intensive Care Unit of Riberalta, Bolivia.
Method: A cross sectional study was conducted with 141 patients who were admitted with this diagnosis in the period June 2006-August 2008.
Results: The most represented age group was 60 years and over (37.6%), while acute coronary syndrome was the main precipitating factor (29.8%) and cardiomyopathy the fundamental causal factor (36.2%). The most common clinical presentation was acute decompensation (39.7%) and the highest percentage of patients had a hospital stay of 7 or more days (64.5%), in which heart failure was more representative (66%) and living discharged patients were more prevalent (80.9%). The largest proportion of patients received potassium-sparing diuretics (90.5%), beta blockers (96.9%) or the association of inhibitors of angiotensin converting enzyme and antagonists of angiotensin II receptors with one of them (95.2 and 94.1% respectively) . The risk of dying was 54 times higher in patients requiring vasoactive drugs, and 9 times in those using digitalis.
Conclusions: Female sex predominated with 60 and more years. Cardiogenic shock, acute pulmonary edema and the number of admissions were the main determinants of mortality. The use of hormone-blocking drugs was favorably associated with survival; the opposite happened with the inotropes.
