Dilated Cardiomyopathy-Cardiac Magnetic Resonance (DCM-CMR) Ancillary Study
The Dilated Cardiomyopathy-Cardiac Magnetic Resonance (DCM-CMR) Study is an ancillary study from the parent study, DCM Precision Medicine Study. The rationale for the DCM-CMR study is to leverage cardiac magnetic resonance (CMR) imaging to detect earliest findings of DCM in the at-risk family members enrolled into the parent study.
A Registry Study on Biomarkers of Takayasu's Arteritis (ARSBTA)
Takayasu arteritis is a chronic vasculitis mainly involving the aorta and its main branches such as the brachiocephalic, carotid, subclavian, vertebral, and renal arteries, as well as the coronary and pulmonary arteries. Inflammation causes segments of the vessels to become narrowed, blocked, or even stretched, possibly resulting in aneurysms. The …
