简要总结
Background:
Heart failure (HF) is a public health burden. Studies have shown a link between inflammation, myocardial dysfunction, and HF. Researchers want to use psoriasis as a disease model of chronic inflammation to further study the link between inflammation and myocardial dysfunction.
Objective:
To learn if chronic inflammation affects the heart and if taking a biological medicine for chronic inflammation helps improve how the heart works.
Eligibility:
Adults ages 18 and older who have moderate to severe psoriasis, and healthy adult volunteers.
Design:
Participants will be screened with a medical history. They may take a pregnancy test.
Healthy volunteers will have 1 visit. Those with psoriasis will have a second visit 1 year later.
Participants may give blood samples. They may have a heart function test. They may have a heart imaging test, and may get a contrast agent. If so, it will be injected into a vein.
Participants may have positron emission tomography/computed tomography tests. They will lie on their back on a padded table with their arms straight overhead. They may get radioactive drugs through an intravenous (IV) catheter. They will get stress medicines through the IV. These drugs mimic exercise and increase blood flow through the heart.
Participants may have cardiac magnetic resonance imaging. The scanner is a large tube. Participants will lie on a table that slides in and out of the tube. They will get gadolinium contrast in a vein to improve the pictures. They may get stress medicines. Coils will be used to help make the pictures.
Participation for healthy volunteers will last 1-2 days. Participation for those with psoriasis will last 14 months.

详细描述
Study Description:
Heart failure (HF) remains a significant public health burden despite expanding and improving treatment options. Clinical and pre-clinical studies have demonstrated compelling relationships between inflammation, myocardial dysfunction, HF and adverse clinical outcomes. In this study to be conducted at the NIH Clinical Center, we propose to utilize psoriasis as a disease model to study how chronic inflammation effects myocardial perfusion, measured by myocardial flow reserve (MFR) on positron emission tomography (PET) and cardiac MRI (CMR), and myocardial function and tissue composition measured by multi-modality cardiovascular imaging.
Objectives:
- To test the hypothesis that chronic inflammation is a driver of perturbances in myocardial perfusion, function, and tissue composition
- To test the hypothesis that biologic treatment for psoriasis will be associated with longitudinal improvement in myocardial perfusion, function, and tissue composition
- To characterize immune cell subsets and their association with myocardial perfusion, function, and tissue composition in chronic inflammation
- To explore how chronic inflammation may alter myocardial energetics and metabolism
