Abstract

Purposes: To investigate the H2FPEF score in heart failure patients with preserved ejection fraction. Subjects and Methods: A cross-sectional study with follow-up was conducted on 171 patients diagnosed with heart failure with preserved left ventricular ejection fraction at the Cardiology Department – Cardiology Center,Hue Central Hospital from May 1st, 2023 to April 30th, 2024. Results: The majority of patients in the study sample were taking two or more antihypertensive medications, 5 patients were not using any antihypertensive medication, and 16 patients were using only one antihypertensive medication. The proportion of patients using two or more antihypertensive medications was 87.1%. Old age (>60 years) was the most frequent risk factor, while BMI > 30 kg/m² was the least frequent risk factor. The group with an H2FPEF score of 3-5 constituted the largest proportion of the study sample (56.7%). There was a difference in the average systolic and diastolic blood pressures between the groups (p<0.05). The left atrial diameter on echocardiography differed among the H2FPEF groups, with higher H2FPEF scores associated with larger left atrial diameter. Similarly, the E/e’ ratio and pulmonary artery systolic pressure (PASP) gradually increased, showing statistically significant differences between the H2FPEF groups (p<0.05). The parameters of left ventricular diastolic diameter, left ventricular systolic diameter, and ejection fraction (EF) did not differ between the groups (p>0.05). Conclusion: There are statistically significant differences in the characteristics of heart failure patients with preserved ejection fraction and the H2FPEF score among the study groups.
