How is Attr-CM diagnosed?

ATTR-CM is diagnosed by a series of tests, which may include an EKG, an echocardiogram, a cardiac MRI and nuclear imagery. This is a difficult condition to diagnose due to its waves symptoms, which can imitate many other conditions.

Jump at the main dishes to remember.

Medical history and physical examination

When a health care provider suspects that someone has atr-cm, he will obtain the person’s medical history and carry out a physical examination. The supplier may request whether there are family history of heart disease, heart failure or cardiomyopathy. If there are enough red flags for ATR-CM, the supplier will likely order additional tests.

Genetic tests

Genetic tests are a useful tool for distinguishing between the wild type and the hereditary anti-CM. If the hereditary attachment is diagnosed, parents in the first degree must be offered genetic tests.

Echocardiogram

An echocardiogram (Echo) cannot diagnose ATR-CM, but it can give clues that suggest that the ATR-CM can be a possibility. You will find below some information on what an echo may and cannot provide:

• Identify changes to heart structure
• Determine to what extent the pump heart (ejection fraction)
• Cannot distinguish between hereditary and wild Attr-CM

Ekg

An electrocardiogram (EKG) is a non -invasive test which examines the electrical activity of the heart. An EKG will present low-voltage models in around 40% of people with ATR-CM. Although it is not a diagnostic tool for ARTR-CM, it can help detect the condition and provide more information to the supplier.

Cardiac MRI

Cardiac magnetic resonance imaging (MRI), also known as CMR, is a scan that provides a detailed look on the heart. It can exclude other causes of cardiac changes, but cardiac MRI alone cannot diagnose ATR-CM. There may be results that suggest amyloidosis.

Nuclear imaging

Nuclear scintigraphy is a type of nuclear imaging which is the pillar diagnostic tool for ATR-CM. It uses a very small amount of radioactive tracker injected into the blood, which binds to amyloid deposits. When the person is scanned, suppliers can view the amount of deposits in the heart.

Blood tests

Bloody tests play a key role in the diagnosis of the AMYLOIDHYPAATHY AMYLOIVE CARDIOMYOPATHY). They help to exclude other forms of amyloidosis, in particular the amylosis of the light chain (AL), which requires different treatment.

This is generally done by serum and urinary tests to detect abnormal free light chains and monoclonal proteins. In ATTR-CM, these markers are generally absent.

Although blood tests cannot confirm ATR-CM, they are essential to shrink the diagnosis and guide the need for an additional genetic imaging.

Biopsy of fatty pads

Biopsy on fatty material pads is a mini-invasive procedure used to detect amyloid deposits and can help diagnose ATR-CM (amyloid cardiomyopathy of transthyretin).

It is a question of taking a small sample of abdominal fat, generally with a needle, and examining it under a microscope using special spots to identify the amyloid. Although a positive result confirms the presence of amyloid in the body, it does not determine the type, so additional tests are necessary to differentiate between ATR and other forms such as AL.

Biopsy on fatty materials is a useful first step, especially when heart biopsy is not immediately necessary or feasible.

Who gets ATR-CM?

There are two types of ATR-CM, hereditary and wild type. Hereditary ATT-CM is a hereditary genetic mutation which means that transthyretin protein becomes distorted. The Wild TYCT ATT-CM occurs as an age-related change in the protein of transthyretin.

People who have a hereditary ATR-CM inherited him from their family. It is more common in the people of:

• Portugal
• Brazil
• Japan
• Suede

The Hereditary ATR-CM variant found in the United States affects 3% to 4% of all African-Americans.

The wild TAP-CM is not a genetic mutation, but a change linked to age in the protein of transthyretin. It tends to occur in men over 60 years of age.

ATR-CM signs and symptoms

ATR-CM symptoms can be subtle or overlap other diseases, which lends to the under-diagnosed condition. You will find below a list of ATRAT-CM symptoms which can be felt:

• Shortness of breath
• Swelling of the lower limbs
• Chest congestion
• Cough
• Whistling breathing
• Increase in heart rate
• Confusion
• Palpations

ATR-CM wild-type people can also suffer from carpal tunnel syndrome and vertebral stenosis.

Treatments for ATR-CM

Astr-CM treatments have undergone significant development in recent years. It was once a condition where symptoms were only managed; Now, some drugs can stop progress, but drugs cannot reverse heart damage. The drugs used to treat ATR-CM are:

• Amvuttra (Vutrisiran) works by slowing down the production of protein from transthyretin.
• Attrup (Acoramidis) and Vyndamax / Vyndaqel (Tafamidis) work by stabilizing the protein of transthyretine made in the liver.

Main to remember

• ATTR-CM is a rare condition that makes the heart stiffens and pumps blood less effectively, which leads to heart failure.
• The diagnosis requires several tools, such as an EKG, an echocardiogram and nuclear imaging.
• If you have family history of ATR-CM or suspect symptoms, contact your health care provider.
