| Outline of Final Research Achievements |
We performed the histological analysis and the study using biomarkers such as B-type natriuretic peptide (BNP) for patients with heart failure with preserved ejection fraction (EF)(HFpEF). Immuno-histological staining for microvascular endothelium was successful. We are now performing statistical analysis for the microvascular density. Additionally, we found that bioactive BNP ratio differ between patients with HFpEF and heart failure with reduced EF, and reported it.
Then, we tested the hypothesis that microvascular embolization into coronary artery was associated with diastolic function, and found some relationships. But since only microvascular embolization is insufficient for elevation in diastolic stiffness, and will continue to develop this finding to experimental HFpEF model in canine.
