Background: Narrower retinal arterioles and wider retinal venules have been associated
with negative cardiovascular outcomes. We investigated whether retinal vessel calibers are …

Leptin, a peptide discovered more than 10 years ago, decreases food intake and increases
sympathetic nerve activity to both thermogenic and nonthermogenic tissue. Leptin was …

Background: It is suggested that the integration of maximal myocardial blood flow (MBF)
and coronary flow reserve (CFR), termed coronary flow capacity, allows for comprehensive …

Background— Although cardiac magnetic resonance (CMR) and positron emission
tomography (PET) detect different pathological attributes of cardiac sarcoidosis (CS), the …

There is accumulating evidence for the existence of a phenotype of isolated cardiac
sarcoidosis (ICS), or sarcoidosis that only involves the heart. In the absence of biopsy-confirmed …

Background : Besides body mass index (BMI), other discriminators of cardiovascular risk are
needed in obese patients, who may or may not undergo consideration for bariatric surgery. …

Prior estimates of radiation-absorbed doses from 82 Rb, a frequently used PET perfusion
tracer, yielded discrepant results. We reevaluated 82 Rb dosimetry using human in vivo …

Aims Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart
transplant (OHT) survivors. Effective non-invasive screening methods are needed. Our aim …

Background: Cardiac dysfunction and cardiovascular events are prevalent among patients
with chronic kidney disease without overt obstructive coronary artery disease, but the …

Purpose In clinical cardiac 82 Rb PET, globally impaired coronary flow reserve (CFR) is a
relevant marker for predicting short-term cardiovascular events. However, there are limited …
