Introduction Heart failure represents one of the main causes of hospital admissions, with a high rate of complications; however, its approach does not seem to have improved during recent years. Objectives To become acquainted with the epidemiologycal and clincial profile; to analize the therapeutic measures and the evolution of patients who were admitted due to descompensated heart failure, during the period of hospitalization, and three months later. Material and Methods Prospective multicenter register of hospitalized patients due to descompensed heart failure in 31 facilities throughout the country that accepted the invitation to participate in the register. Variables related to the presentation and the hospital evolution were analized, as well as the variables 90 days after hospitalization. Results A total of 736 patients were included, with an average of 74 years of age (64-82), 41% women, 75% hypertensive, 27% diabetics, 20% previous infarction, 30% chronic atrial fibrillation, 17% chronic kidney failure, 18% COPD. Only 29% was of ischemic-necrosis etiology. 47% had been admitted over the last year due to heart failure. The most frequent causes of descompensation were infections, stopping treatment, and dietary indiscretion. The severe presentations (cardiogenic shock, acute pulmonary edema, anasarca) occurred in 30% of the individuals. 60% patients were admitted in the critical unit. The median stay in hospital was of 7 (5-11) days. In-hospital mortality was of 8%. After 90 days, readmittance was of 24.5%, and post discharge mortality was of 12.8%. Conclusions The present register confirms that this is a population made up of older adults with a high incidence of cormobilities. Many descompensations occur due to factors that may be prevented. The rate of complications is high and did not reduce over the last decade.
