Introduction. Heart failure is one of the main causes of cardiovascular morbidity and mortality. Research stated that heart failure patients who have undergone 3 rehospitalizations have a survival rate of <50% within 1 year. Therefore, the purpose of this study is to characterize the risk factors that contribute to the occurrence of heart failure rehospitalization.
Method. This is a retrospective analysis of 113 patients with a first hospitalization for heart failure at Prof. I.G.N.G. Ngoerah Hospital between July 2018–February 2020. We collected and compared demographic data, clinical findings, electrocardiogram, laboratory, and echocardiography parameters during the first hospitalization between rehospitalized and non-rehospitalized patients. Rehospitalization was defined as recurrent hospital admission due to worsening heart failure symptoms. Patients were followed for rehospitalization events until death or November 2021.
Results. The rehospitalization rate in this study was 62.8% during a median follow-up of 234 days (12–1098 days). The average of heart failure rehospitalizations during follow-up was 1.73 times (±1.97), with an average length of stay of 6.40 days (±3.27 days). We discovered that the presence of mid/apical rales at admission (odds ratio [OR] 3.509; p=0.027), hyponatremia (<135 mmol/L) at pre-discharge (odds ratio [OR] 3.840; p=0.015), and tricuspid annular plane systolic excursion (TAPSE) values <1.80 cm (odds ratio [OR] 2.905; p=0.020) were independent risk factors for rehospitalization due to worsening heart failure symptoms. Patients with these three independent risk factors have a probability of 96.24% being readmitted.
Conclusion. Mid/apical rales at admission, hyponatremia at pre-discharge, and TAPSE values <1.80 cm in patients admitted for heart failure are associated with further rehospitalization.
