Abstract

Aims: To characterize the clinical features in patients hospitalized for heart failure in Taiwan and to identify predictors for one-year mortality. Methods and Results: We enrolled 3084 heart failure patients who were admitted to one medical center in Taiwan from 1986 to 2007. Individuals in the current study were divided into two groups according to age greater than 65 years or not. Elevated blood urea nitrogen and ventricular tachycardia episode were predictors for 1-year mortality in both groups. Besides these predictors, symptoms of orthopnea, weakness, decrease urine output and lower blood pressure also predicted 1-year mortality in the younger group but had no significant influence in the older group. Different from the younger group, prolong QRS duration and potassium increased 1-year mortality in elderly patients. After multivariate analysis, low diastole blood pressure were predictors for 1-year mortality in both group. Besides blood pressure, ventricular tachycardia episode were also a predictor for mortality in younger group. In the elderly group, poor appetite, elevated C- reactive protein and prolong QTc interval were predictors for 1-year mortality. Conclusion: Lower diastole blood pressure are predictors of higher mortality in Taiwan population. Ventricular tachycardia episode is also a poor sign. Electrolyte and nutrition status have less effect in1-year mortality of Taiwan heart failure population.
