Early Screening for Cardiac Amyloid Using a History of Bilateral Carpal Tunnel Syndrome
Investigations in Early Screening for Cardiac Amyloid Through History of Bilateral Carpal Tunnel Syndrome
Cardiac amyloidosis is a condition where abnormal protein deposits build up in the heart, making it stiff and causing it to work less effectively. One common type is caused by a normal blood protein called transthyretin (TTR), which can become unstable and form these deposits. When this happens, it is called ATTR-CM, a form of heart disease caused by TTR protein buildup. This can lead to symptoms like tiredness, shortness of breath, or swelling.
Bilateral carpal tunnel syndrome (CTS) is recognized as an early clinical sign of systemic amyloidosis, especially in the context of TTR amyloidosis, where amyloid deposits accumulate in the median nerve. Early identification of cardiac amyloidosis, particularly in patients with bilateral CTS, may allow for earlier intervention with disease-modifying therapies, such as tafamidis, which has been shown to improve survival and reduce hospitalizations in patients with cardiac amyloidosis.
The purpose of this study is to identify patients to evaluate them for previously undiagnosed cardiac amyloidosis. The collected information will help estimate the prevalence of cardiac amyloidosis among participants with prior bilateral CTS using a PYP nuclear scan (technetium-99m pyrophosphate scan). A PYP scan is a special heart imaging test that helps doctors see if certain abnormal proteins are building up in the heart. It's mainly used to help diagnose cardiac amyloidosis.

실험적: History of Bilateral Carpal Tunnel syndrome
|
In this study, Technetium-99m pyrophosphate (Tc-99m PYP) cardiac scintigraphy will be performed in participants with a documented history of bilateral carpal tunnel syndrome, a recognized extracardiac manifestation associated with transthyretin (ATTR) amyloidosis.
The purpose of this imaging intervention is to evaluate for the presence of cardiac transthyretin amyloid deposition in an at-risk population.
