Some people living with transthyretin amyloid cardiomyopathy (ATTR-CM) experience musculoskeletal issues that may point to the condition years before diagnosis.
In fact, your doctor may learn about tendon ruptures or other musculoskeletal problems, such as a biceps tendon rupture, rotator cuff injury, or lumbar spinal stenosis (narrowing around the nerves in the lower back), before you’ve had any heart symptoms at all.
