Introduction Heart failure is a significant syndrome that has a high burden. To date 3 subgroups have been divided by left ventricular ejection fraction according to 2016 The European Society of Cardiology (ESC) heart failure guideline (Heart failure with reduced, mid-range and preserved ejection fraction). These subgroups might have different outcomes. The aim of this study to define the mortality and heart failure rehospitalization rate of all heart failure patients and compare data of 3 heart failure subgroups at Phang Nga hospital.
Method This is a cross-sectional descriptive study. The Phang Nga hospital inpatient charts were review from October 2015 to September 2017 with principal diagnosis codes I11.0 and I50.* of International Classification of Disease (ICD-10). The primary outcomes are in-hospital mortality, 1-year mortality and 1-year heart failure rehospitalization rate. The secondary outcomes are the comparison of outcomes between 3 subgroups.
Results 289 patients were enrolled. Most of the patients were elderly with mean age 71.6 years and slightly more female (53.3%) with have the underlying disease of hypertension (80.3%) and dyslipidemia (67.1%). About 51.8% of the patients are in Heart failure with preserved ejection fraction subgroup. The in-hospital mortality, 1-year mortality, and rehospitalization rate due to heart failure were 4.2% 18.0% and 34.6 %, respectively. There is no significant difference between 3 subgroups.
Conclusion The outcomes show 18.0 % of one-year mortality rate and 34.6 % of one-year heart failure rehospitalization rate. Among three subgroups, There was no significant difference in mortality and rehospitalization rate.
