COULD THESE SYMPTOMS ACTUALLY BE ATTR-CM?
IN LOWER BACK
If you’re over 60 years old with heart failure symptoms, carpal tunnel syndrome and/or lumbar spinal stenosis, and your heart and blood pressure medicines only make you feel worse, you could have a life-threatening disease. Scroll down for more about transthyretin-mediated amyloidosis, or ATTR-CM.
Amyloidosis is a group of diseases in whichcertain proteins change shape, or “misfold,” and can then build up in different parts of the body.
HOW DOES ATTR-CMAFFECT THE HEART?
ATTR-CMAFFECTS MORE THAN THE HEART
ATTR-CM AFFECTS MORETHAN THE HEART
Because the many different symptoms ofATTR-CM can look similar to those of other diseases, it's important to know what information could be helpful to your doctor in considering a diagnosis.

IF YOU HAVE HEART FAILURE, TELL YOUR DOCTOR
IF YOU HAVE HAD ANY OR ALL OF THESE SYMPTOMS.
IT COULD BE ATTR-CM.
- Heart failure
- Feeling worse when taking heart medications such as beta blockers, ACE inhibitors, or ARBs
- Echocardiography showing increased left ventricle wall thickness
- An electrocardiogram reading of low electrical activity relative to left ventricle thickness
- Arrhythmia, also known as an irregular heartbeat
- Narrowing of the aortic valve ("aortic stenosis")
- Nerve damage that can affect the heart, blood vessels, bladder, intestines, sweat glands, and pupils (“autonomic neuropathy”)
- Stomach or digestive problems like diarrhea, constipation, and nausea
- Unexplained weight loss
- Dizziness or lightheadedness when standing up
- Sexual impotence
- Nerve damage that can affect muscle movement and sensation, and/or cause tingling, numbness, and pain in the arms and legs
- The appearance of tiny threads or “floaters” in one’s field of vision (“vitreous opacity”)
- Glaucoma, a buildup of fluid in the eye that can lead to blindness
- Biceps tendon rupture
- Pain and numbness in the lower back and legs due to a narrowing of the lower spinal canal (“lumbar stenosis”)
- A history of carpal tunnel syndrome
- Surgery to resurface or replace parts of the hip or knee joint (“arthroplasty”)
WHAT DOES MY DOCTOR DO NEXT?
Your doctor may perform some tests to get more detailed information about your heart, including an electrocardiogram, an echocardiogram, or a cardiac MRI.
If those tests suggest that ATTR-CM might be causing your symptoms, your doctor may order blood and urine tests to rule out other diseases.
Next steps can include procedures that might definitively diagnose ATTR-CM, like a cardiac imaging scan.
This noninvasive procedure can help show if transthyretin deposits are forming in your heart, an indication that you have ATTR-CM. In some cases, your doctor will order a heart biopsy to look for transthyretin deposits.
If you are diagnosed with ATTR-CM,
there's a treatment that can help.
