英文摘要
Heart failure with preserved ejection fraction (HFpEF) is currently being studied intensely as several
large trials of drug therapies have failed to benefit patients. Better characterization of these patients is
important, and there are open questions regarding microvascular disease and remodeling in the
HFpEF population. New MRI methods could be ideal to better characterize and understand HFpEF
and its response to treatments. This project seeks to develop, evaluate and apply new MRI methods
for high-end perfusion imaging. These methods will estimate endo/epi ratios across the cardiac cycle
in free-breathing studies, which will be used along with other new MRI measurements and blood
biomarkers to provide new information about microvascular disease. This is of particular value for
assessing HFpEF.
The aims and methods of this project are to (1) develop and compare new 2D radial simultaneous
multi-slice (SMS) and 3D stack-of-stars (SoS) acquisitions and reconstruction methods for
quantitative perfusion measurements. (2) To validate the new 2D radial SMS and 3D SoS free-
breathing methods in an animal model of HFpEF, and in humans to further characterize the new
methods by comparison to a more standard MRI method and to dynamic PET. (3) To use the
methods along with fibrosis quantitation and other MRI measures to characterize perfusion and
fibrosis changes over time in patients with HFpEF. This will give more insight into non-invasive MRI-
based perfusion and fibrosis biomarkers and how they complement other biomarkers and give insight
into different subtypes of HFpEF.
The relevance to public health is that HFpEF is a leading cause of disability and death and no
effective treatment is known. The development and use of accurate and repeatable measurements of
perfusion and their combination with fibrosis quantitation will lead to accelerated evaluation of clinical
therapies. The project will also provide new tools and knowledge for better management of patients
with HFpEF. The proposed approach will be extended to better understand a range of cardiac
diseases.
