Improving insights into the heterogeneous HFpEF syndrome through microvascular research
English summary
Background
Heart failure with preserved ejection fraction (HFpEF) is a condition affecting how the heart fills with blood. It is linked to microvascular dysfunction (MVD), which involves problems in small blood vessels throughout the body. This dysfunction may play a key role in HFpEF, but its specific mechanisms and contributions to the condition are unclear.
What We Discussed
- HFpEF is a complex condition with many causes, such as diabetes, high blood pressure, and obesity. However, it is not fully understood which factors directly cause HFpEF.
- MVD could be central to HFpEF as it affects blood flow and oxygen delivery to tissues.
- MVD is not unique to HFpEF and occurs in other conditions, making it difficult to determine its exact role in HFpEF development.
What We Propose
- Translational research combining patient data and animal studies could help identify specific microvascular changes driving HFpEF.
- Identifying patient subgroups with different types of MVD could guide personalized treatments. For example:
- Patients with endothelial dysfunction (poor blood vessel relaxation) might benefit from treatments targeting nitric oxide pathways.
- Patients with other types of MVD might need different therapies.
Conclusion
A better understanding of microvascular problems could improve HFpEF diagnosis, treatment, and monitoring. Future studies should match animal models and patient subgroups for more accurate findings and focus on functional microvascular tests to design effective therapies.
