Brief Summary
This study's main specific aims are;
- 1.To develop robust acquisition and reconstruction methods specifically for the study of microvascular cardiac remodeling with MRI which will include very innovative quantitative perfusion methods, as well as fibrosis quantification, longitudinal strain, and phase contrast imaging for flow.
- 2.Test the new methods for identifying the clinical task of characterizing HFpEF.

Outcome Measures
Primary Outcomes (1)
Image quality improvement
comparison of perfusion, myocardial perfusion reserve (MPR), function possibly including strain, and extracellular volume (ECV, from T1 mapping).
Time in the scanner to be 60-90 minutes.
Study Arms (1)
MRI vs.PET with/without Cardiac disease
EXPERIMENTALAdenosine Regadenoson O-15 Labeled radioactive water MRI PET Imaging
Interventions
Adenosine: 0.14mg/kg/min for 6 min. IV injection for MRI perfusion
0.4mg in 5ml, given as a rapid (10 seconds) IV injection for MRI perfusion.
O-15 labeled radioactive water: Up to 50mCi IV injection at rest and again at hyperemia for PET Imaging
Pass dynamic contrast enhanced MRI scans will be performed at rest and during hyperemia caused by either adenosine infusion or regadenoson
Quantitative PET imaging with O-15 labeled radioactive water will be given at a different day
Eligibility Criteria
You may qualify if:
- All participants will be over the age of 18 and able to provide consent
- Group A (volunteers, with or without cardiac disease): Volunteers will be available for at least one study visit
- Group B (HFpEF patient volunteers): Volunteers will have a diagnosis of HFpEF and be safe to be imaged with MRI
You may not qualify if:
- minors
- Critically ill patients, patients on ventilators, patients with unstable angina or with hypotension, asthmatics, and other patients whose medical care or safety may be at risk from undergoing an MRI examination will be excluded.
- Patients with claustrophobia will also be excluded from the study if this cannot be controlled with standard methods (valium or benadryl).
- Patients with contraindication to MRI (metal implants, or certain types of heart valves),
- pregnant patients, , mentally disabled patients and prisoners will be excluded from this study. (All criteria apply to patients and normal volunteers).
- Gadolinium nephrotoxicity will be addressed by having patients with abnormal kidney function (GFR\<30) excluded from the study due to the (very small) risk associated with gadolinium contrast agents.
- This threshold may be modified, depending on practices determined by the Radiology Department and the IRB.
- Patients with a known allergy or contraindication to Adenosine and/or Regadenoson will be excluded from stress MRI cohorts.
- All participants that will receive a stress agent will refrain from consuming caffeine for at least 12 hours prior to each MRI
- Subjects with a known contraindication to Adenosine and/or Regadenoson will only be enrolled in scans where no stress agent will be administered
