What is Idiopathic Hypertrophic Subaortic Stenosis?
Lying at the center of your cardiovascular system is your heart. Your heart is the organ that pumps blood to every cell in your body by means of your body’s blood vessels. Your blood contains oxygen that your cells must have in order to live and function.
The literal meaning of cardiomyopathy is "heart muscle disease" It is used to refer to the deterioration of the functioning of your myocardium (heart muscle). Cardiomyopathy is a disease that hinders your heart’s ability to pump blood.
Idiopathic hypertrophic subaortic stenosis is a form of cardiomyopathy that is evidenced by your heart muscle (myocardium) becoming abnormally hypertrophied or thickened. This thickening makes it harder for blood to exit your heart. This, in turn, makes your heart have to work harder in order to pump blood. Idiopathic hypertrophic subaortic stenosis may also affect the electrical system of your heart.
Other names Idiopathic Hypertrophic Subaortic Stenosis might go by:
Idiopathic hypertrophic subaortic stenosis is referred to by other names. It is also known as hypertrophic cardiomyopathy, asymmetric septal hypertrophy, familial hypertrophic cardiomyopathy, hypertrophic obstructive cardiomyopathy and hypertrophic nonobstructive cardiomyopathy.
Fortunately, idiopathic hypertrophic subaortic stenosis is a rare disease. It is a disease that affects somewhere around 1 in 500 people in the United States.
People of all ages may get idiopathic hypertrophic subaortic stenosis. However, when younger people are afflicted with this disease, it is more apt to be a serious kind of idiopathic hypertrophic subaortic stenosis. Men and women are affected equally by this disease.
One of the main things that leads to idiopathic hypertrophic subaortic stenosis is genetic mutations. These are defects that occur in your genes. Doctors think that these genetic mutations may result in your heart muscle becoming abnormally thickened.
Another factor that may have a role in bringing about idiopathic hypertrophic subaortic stenosis is an abnormal arrangement of the muscle fibers of your heart. This is something that may have a part in causing your heart to beat in an irregular rhythm.
Genetics is #1 Risk Factor for Idiopathic Hypertrophic Subaortic Stenosis
There is one primary risk factor for the development of idiopathic hypertrophic subaortic stenosis. It is heredity. It has been determined that the children of people who are afflicted with this disease have a 50% chance of inheriting the genetic mutation that may result in idiopathic hypertrophic subaortic stenosis.
Some people have no signs or symptoms at all with idiopathic hypertrophic subaortic stenosis. These people are not even aware that they have this disease until it is revealed while undergoing a routine medical exam.
Signs and Symptoms of Idiopathic Hypertrophic Subaortic Stenosis
However, there are several signs and symptoms that you may have, which may be an indication of idiopathic hypertrophic subaortic stenosis. Some of these are:
- Fainting that takes place especially during the time that you are exercising or doing some other activity
- Shortness of breath
- Shortness of breath that occurs while you are lying down
- A reduced tolerance for activity
- Chest pain
- Heart failure
- Palpitations (heartbeat sensations that feel like your heart is racing or pounding)
- Lightheadedness that takes place especially after you have exercised or done some other activity
- Hypertension (high blood pressure)
- Irregular heartbeat (heart arrhythmia).
