Epicardial Adipose Tissue and Heterogeneity Parameters Combined with Inflammatory Cells to Predict the Value of Heart Failure with Preserved Ejection Fraction Patients Post Myocardial Infarction
Authors' conclusion
In patients with chronic MI, normal LVEF, and no prior PCI, the occurrence of HFpEF is not correlated with infarct volume; however, BMI, diabetes, monocyte, LV EAT, and EAT entropy are independent risk factors for HFpEF with significant predictive value, with the highest predictive efficacy observed monocyte and when combining EAT entropy and LV EAT. Additionally, both overall and local EAT volumes exhibit a moderate positive correlation with leukocytes,monocytes and inflammatory markers, and were also positively correlated with diastolic dysfunction. This suggests that, in clinical practice, beyond traditional indicators, there should be an increased focus on EAT heterogeneity and perivascular EAT in MI patients with normal LVEF who have not undergone PCI to to reduce the incidence of HFpEF.
Study context

Further findings
| Outcome | P value |
|---|---|
| Baseline differences HFpEF vs non-HFpEF | P < 0.05 |
- Baseline differences HFpEF vs non-HFpEF: BMI, diabetes, renal failure, leukocytes, neutrophils, monocytes, total EAT, EAT entropy, LV EAT, left atrial end-systolic volume (LAESV), TG, NHR, MHR, LACI differed
Baseline differences HFpEF vs non-HFpEF
- No significant differences in age, sex and infarct volume
Correlations of EAT volume
- Overall and local EAT volumes positively correlated with leukocytes, monocytes, MHR and SIRI
- EAT volume positively correlated with LACI (diastolic dysfunction marker)
