title: [Cross-sectional study of heart failure of patients intaked in an Internal Medicine Service in the third level hospital in mixed area. Part III: mortality analysis].
abstract: OBJECTIVE
  To establish the characteristics of the deceased in intaked patients by heart failure.
  
  
  METHODS
  A cross-sectional study of the intaked patients in the Internal Medicine Service in the Hospital Clínico Universitario de Santiago de Compostela between 1999 to 2003. The variables analized were: sex, age, days of hospital stay, number of intaked by failure cardiac, reason for admission (guide symptom), hypertension, diabetes mellitus, cardiac disease, fibrillation atrium, previous treatment with beta-blockers, blood pressure in the admission moment, to make echocardiography, disfunction systolic, etiology, deceased, treatment at the end. The statistical analysis was performed with cualitative and cuantitative measures, chi-cuadrado and t-student.
  
  
  RESULTS
  248 patients were accepted for the study, with the mortality rate rising 8.6% (21 patients). We did not observed differences between sexes, but the median age in death patients was greater than other patients. The median income was 5 days, letter than study population. The hypertension prevalence (30 vs. 42.6%, p = 0.27) and ischemic cardiopathy (30 vs. 27.7%, p = 0.82) did not showed differences with the population. The hypertension prevalence in women (16.7 vs. 35.7%, p = 0.21) and the ischemic cardiopathy prevalence in men (50 vs. 21.4%, p = 0.20) did not showed differences. It made echocardiography in 21.0% of death patients, p = 0.76. The systolic disfunction prevalence was bigger in death patients (80 vs. 41.3%), this difference was not significant statistically.
  
  
  CONCLUSIONS
  The older patients showed letter survival. We did not observe any influence of sex or left ventricular systolic function on mortality in patients with heart failure.
