Official title
A Three-Arm, Observational, Pilot Study of 68Ga-Fibroblast Activation Protein Inhibitor (FAPI) Positron Emission Tomography in Heart Failure
Overview
The purpose of this study is to assess the performance of 68Ga- FAPI PET in heart failure with preserved ejection fraction (HFpEF)
Interventions
- Drug 68Ga-FAPI (gallium-68-labeled fibroblast activation protein inhibitor)
68Ga-FAPI is a gallium-68 fibroblast activation protein inhibitor that will be injected into subjects during a PET (positron emission tomography) scan
Primary outcome measures
- Myocardial 68Ga-FAPI (68Ga-Fibroblast Activation Protein Inhibitor) volume [Time frame: Baseline and 6 Months]
- Mean Standardized Uptake Value (SUVmean) and Max Standardized Uptake Value (SUVmax) [Time frame: Baseline and 6 Months]
- Area of 68Ga-FAPI (68Ga-Fibroblast Activation Protein Inhibitor) uptake [Time frame: Baseline and 6 Months]
- 68Ga-FAPI target-to-background ratio [Time frame: Baseline and 6 Months]
Eligibility criteria
HFpEF Group Inclusion:
- Patients aged ≥ 30 years old with exertional dyspnea (NYHA II and III) and LVEF ≥50%
- BMI ≥ 30
- New diagnosis of HFpEF based on RHC at baseline (elevated PCWP at rest and/or during exercise)
HFpEF Group Exclusion:
- Primary cardiomyopathy or pericardial disease or ≥ moderate valvular disease
- Dyspnea due to lung disease or CAD
- Severe anemia, liver, or renal disease
- Active cancer
- Systemic active inflammatory or autoimmune disease (e.g. rheumatoid arthritis, SLE, etc.)
- Recent hospitalization (< 30 days) or coronary revascularization (< 90 days)
- Patients already taking SGLT2i and/or GLP-1A
- Pregnant or breastfeeding
- Inability to tolerate supine position for the PET/CT or CMR scans.
- Contraindications for safe CMR scanning (e.g., uncontrolled claustrophobia, cochlear implant, implanted neural stimulator)
- Known gadolinium allergy
- Presence of implantable cardiac pacemaker or defibrillator or mechanical valve.
Cardiac Sarcoid Group Inclusion:
- Ambulatory patients aged ≥ 18 years old
- New referrals to the Sarcoid Clinic with a confirmed but untreated diagnosis of definite or probable CS based on 2014 HRS consensus (see Table 2)
- With a positive cardiac 18F-FDG PET scan within 30 days.
Cardiac Sarcoid Group Exclusion:
- Already on immunosuppressive therapy
- Pregnant or breastfeeding
- Severe liver or renal disease (estimated GFR < 30 or dialysis-dependent)
- Recent coronary revascularization (< 90 days)
- Active cancer
- Known gadolinium allergy
- Inability to tolerate supine position for the PET/CT or CMR scans.
- Contraindications for safe CMR scanning (e.g., uncontrolled claustrophobia, cochlear implant, implanted neural stimulator)
- Presence of implantable cardiac pacemaker or defibrillator or mechanical valve.
Healthy Controls Group Inclusion:
- Adults ≥ 30 years old
- No major chronic disease (cardiopulmonary, inflammatory, autoimmune, cancer, renal or liver impairment, etc.)
- No intake of relevant medication, defined as regular intake of at least one of the following: anticoagulants, antiplatelets, antihypertensive / diuretics, antidiabetics, antiarrhythmic, immunosuppressants, chemotherapy, antibiotics/antivirals/antifungals
Healthy Controls Group Exclusion:
