Abstract

Background: Heart failure with preserved ejection fraction (HFpEF), especially in elderly patients, poses significant challenges in diagnosis and treatment due to non-specific symptoms that can be easily confused with other conditions. Globally, numerous studies have emphasized the importance of early detection of HFpEF to improve prognosis and reduce hospitalization rates. However, in Vietnam, data on the diagnostic rate of HFpEF and related clinical characteristics in elderly patients remain limited. Objective: To determine the prevalence of HFpEF diagnosed using the H2FPEF score and to describe the epidemiological, anthropometric, comorbidities, geriatric, clinical, and paraclinical characteristics of elderly patients hospitalized for unexplained dyspnea. Methods: A descriptive cross-sectional study was conducted from September 2024 to December 2024 at Thong Nhat Hospital. Elderly patients admitted for unexplained dyspnea were evaluated for HFpEF diagnosis using the H2FPEF score. Results: Among 130 elderly patients hospitalized for unexplained dyspnea, 84 patients (64.62%) were diagnosed with HFpEF using the H2FPEF score. The study identified significant associations between HFpEF and factors such as advanced age, female gender, hypertension, atrial fibrillation, chronic kidney disease, and chronic coronary syndrome. Conclusion: The study revealed that 64.62% of elderly patients hospitalized for unexplained dyspnea were diagnosed with HFpEF using the H2FPEF score. Key factors associated with HFpEF include advanced age, female gender, hypertension, atrial fibrillation, chronic kidney disease, and chronic coronary syndrome, highlighting the importance of early screening and management of HFpEF in this patient group.
