Stress echo could unmask hidden heart valve disease in amyloidosis patients

This study looked at 15 patients with a rare heart condition called wild-type transthyretin amyloid cardiomyopathy (ATTRwt) who also had signs of aortic stenosis. Researchers used dobutamine stress echocardiography—a test that uses a drug to make the heart pump harder while imaging it—to see if it could accurately measure the severity of the valve narrowing. The goal was to compare this non-invasive method with the standard invasive measurement to improve diagnosis and avoid unnecessary procedures.
