Abstract

Objectives: To investigate the prevalence of heart failure with preserved ejection fraction (HFpEF) and associated factors in patients with acute myocardial infarction (AMI). Materials and methods: a cross-sectional descriptive study was conducted on patients diagnosed with myocardial infarction who were admitted and treated at Can Tho City General Hospital from March 2025 to August 2025. Results: Among a total of 65 patients, 76.9% were male. There were 25 patients with HFpEF, accounting for 38.5%. The proportion of HFpEF was higher in patients with STEMI (70.0%) compared with those with NSTEMI (24.4%). Similarly, patients with Killip class ≥ II had a higher HFpEF rate (87.5%) compared with those with Killip < II (31.6%). Patients with diabetes mellitus had a significantly higher prevalence of HFpEF compared to non-diabetic patients (63.2% vs 28.3%). Conclusion: HFpEF occurs at a relatively high rate among patients with acute myocardial infarction. Factors such as ST-segment elevation myocardial infarction, higher Killip class (≥ II), and a history of diabetes mellitus were found to be associated with the occurrence of HFpEF.
