NCT07577466
Screening, Characterization, and Longitudinal Follow-up of Patients With Cardiac Amyloidosis
Cardiac amyloidosis is a progressive disorder caused by extracellular deposition of amyloid fibrils in the heart, leading to heart failure and impaired cardiac function. Early diagnosis and targeted therapies are essential to improve patient outcomes. This prospective, single-center study aims to longitudinally follow patients with suspected cardiac amyloidosis to characterize disease progression and assess treatment effects. Participants will undergo cardiac magnetic resonance imaging (resting and exercise stress MRI), magnetic resonance spectroscopy, cardiopulmonary exercise testing (spiroergometry) and blood testing at baseline and at 6, 12, and 24 months

Near-Infrared Spectroscopy Measurements in Chronic Obstructive Pulmonary Disease
Participants were selected based on three groups: healthy, chronic obstructive pulmonary disease, and chronic renal disease. NIRS was used to measure tissue oxygenation on the thenar region of the right hand. A pressure cuff was used to temporarily occlude arterial inflow, thus allowing the response to this to be assessed. The StO2 was plotted against time, and the following variables were calculated, the downslope, upslope, area under curve.
