Hypertrophic Cardiomyopathy - Exams and Tests
The results of an
exercise test may show that you have a higher risk for serious health problems
because of hypertrophic cardiomyopathy. Some doctors recommend an exercise test
before beginning any treatment for hypertrophic cardiomyopathy.
chest X-ray produces a photographic image of the heart
using rays of intense light energy that pass through the body and project an
image on a film. An X-ray can show information about the heart's size and
shape. In later stages of hypertrophic cardiomyopathy, an X-ray may reveal
pulmonary edema, which is fluid buildup in the
cardiac catheterization or coronary angiogram, a long,
thin tube (catheter) is threaded through an artery or vein in the arm or groin
and into the heart to measure pressure in the heart chambers. Dye can be
injected through the catheter to see whether the coronary arteries are blocked,
how well the heart chambers are pumping, and whether heart valves are leaking.
Angiography may be done if the results of the echocardiogram are
inadequate. Angiography may also be used to check if surgery would be an option
for treatment of hypertrophic cardiomyopathy.
Genetic testing can identify some
genes that are related to this condition. Many people who have relatives with
hypertrophic cardiomyopathy wonder if they or their children should have
genetic testing. So far, routine genetic testing is not yet practical because
there are so many possible abnormal genes that cause the disease. Genetic
testing is presently used in a small number of cases when the specific genetic
mutation in the affected relative has been identified. For close relatives of people who have hypertrophic cardiomyopathy, an echocardiogram is the typical test to check their heart.
