Circulating RNAs in Acute Congestive Heart Failure (CRUCiAL) 200 Tradução disponível
The investigators are testing the hypothesis that ex-RNA levels change significantly during decongestion therapy and can be used as a marker of those individuals who respond to CHF therapy (in terms of c...

Patients with HF-rEF These patients have Heart Failure with Reduced Ejection Fraction (EF \< 55% per the protocol). | Ressonância magnética cardíaca Cardiac MRI is a test that allows us to look at how the heart muscle works and the amount of scar tissue in your heart. Screening questions will be asked to make sure that patients are not pregnant, and that they have kidney function tests to confirm that IV contrast used (gadolinium) during the MRI is safe for them. |
