Clinical and Laboratory Predictors of Mortality in Patients with Advanced Heart Failure (Stage D), Data Derived from Rajaie Acute Systolic Heart Failure (RASHF) Data Registry

Abstract

Background: Mortality, morbidity and the burden of the advanced heart failure and also the cost of frequent admissions is high. Several registries were done all over the world to manage the patients with heart failure; however studies about the advanced stage are limited. Objectives: The present study aimed to determine the prognostic predictors of patients with advanced heart failure. Methods: In this study 178 (74.2% male) patients with advanced heart failure (stage D) from 2011 to 2016 were selected according to the following inclusion criteria; highly symptomatic heart failure patients with severe left ventricular (LV) systolic dysfunction (LV ejection fraction less than 30%) who have been admitted for at least two times in the recent year because of decompensation. The data regarding the clinical findings, readmissions, mortality, laboratory tests, electrocardiography, echocardiography, etc. of patients were all derived from Rajaie Acute Systolic Heart Failure (RASHF) data registry. Results: In a 5-year follow-up, we realized that more than 70% of the patients died. The rate of mortality were significantly higher in females (P value = 0.006) and there was a significant correlation between anemia and the mortality (P value = 0.002). There was no remarkable association between the serum creatinine, sodium and uric acid levels with the mortality of the patients. Conclusions: Data about stage D of heart failure are limited. The mortality rate for such patients is relatively high and there's no clear best treatment approach. Large registries and data acquisition of these patients could be helpful for better management approaches.
