How do you test for HCM?

Echocardiogram. An echocardiogram is commonly used to diagnose hypertrophic cardiomyopathy. This test uses sound waves (ultrasound) to see if your heart’s muscle is abnormally thick. It also shows how well your heart’s chambers and valves are pumping blood.

Is HCM genetic?

HCM is the most common genetic heart abnormality. One in 500 Americans is diagnosed with HCM, however, this condition often goes undiagnosed. HCM is autosomal dominant condition, meaning that individuals have a 50% chance of inheriting, or passing on, the predisposition to this disorder to their children.

How do they test for PKD in cats?

Can stress cause a heart murmur in cats?

This can be scary to hear, but the majority of these cats with murmurs never develop heart disease. In fact, sometimes stress alone can cause a murmur.

People with HCM are at higher risk for developing atrial fibrillation, which can lead to blood clots, stroke and other heart-related complications. HCM may also lead to heart failure. It can also lead to sudden cardiac arrest, but this is rare.

What gene causes HCM?

Mutations in one of several genes can cause familial hypertrophic cardiomyopathy, the most commonly involved genes are MYH7, MYBPC3, TNNT2, and TNNI3. Other genes, including some that have not been identified, may also be involved in this condition.

Does HCM skip generations?

Most people with HCM inherited the genetic mutations from their parents, but the mutations can also occur spontaneously. These mutations can pass directly from parent to child, they do not skip a generation. The likelihood of a parent passing the mutation on to a child is about 50 percent.
