Great question! Figuring out which type of ATTR-CM you have is an important step in getting the right treatment. The key test is a genetic test that looks at your TTR gene.
Here's how the process generally works:
- Genetic testing is done using a simple blood sample, saliva, or a cheek swab
- If a TTR gene mutation is found, the diagnosis is hereditary ATTR-CM (hATTR-CM)
- If no mutation is found, the diagnosis is likely wild-type ATTR-CM
Wild-type ATTR-CM cannot be confirmed through genetic testing alone — your doctor will use their clinical judgment based on your overall test results and risk factors. Your doctor may also use imaging tests like an echocardiogram, cardiac MRI, or a nuclear imaging scan to assess amyloid deposits in the heart alongside genetic testing.
It's worth knowing that genetic testing is often straightforward and sometimes even sponsored, meaning there may be no cost to you. Ask your cardiologist or a genetic counselor about getting tested — early answers can make a real difference in your care plan.
