8 The role of heart rate measurement in heart failure patient with preserved ejection (HFpEF) presenting as acute condition: a single centre registry

<h3>Background</h3> Heart failure (HF) has become a major global burden on society, with a 40%–50% prevalence of acute heart failure among patients with Heart Failure with Preserved Ejection Fraction (HFpEF). Due to readmission, heart failure patients in Asia, particularly in Indonesia, have a high rate of mortality and morbidity, which is predicted to double by 2025 and quadruple globally by 2050. <h3>Aim</h3> The aim of this study were to examine associations of heart rate measurements with outcomes in hospitalized patients with HFpEF. <h3>Methods</h3> Using clinical registry data, we performed a retrospective cohort analysis involving 552 patients who were admitted to the intensive care unit with acute heart failure for inclusion criteria. After being discharged, the patients underwent at least 30 days of follow-up. Multivariate logistic regression analysis was used to examine the gathered information. <h3>Results</h3> Of the 552 patients hospitalised for acute heart failure, 82 patients met inclusion criteria. We examined the relationship between readmission rates one year following discharge and HR. The primary outcome of the HR pre-discharge itself was not significantly correlated with the readmission rate with p=0.16 . The HR had set a goal of staying below 80 bpm. Additionally, we discovered a strong association between the potential HR pre-discharge and the earlier we reduced HR during the first 24-hour hospitalization with p=0.02 <h3>Conclusion</h3> Reducing HR as soon in 24 hours can influence HR pre-discharge near the target below 80 bpm. The lower discharge HR presents <i>the better all cause and cardiovascular mortality</i>.
