Muscle Growth You Don’t Want

Posted on Fri 09 December 2016 in misc

Cardiomyopathy (defined as disease of muscle tissue) is one type of muscle growth you don’t want. Here’s why.

This is a serious heart condition in which the muscle becomes inflamed, possibly from an infection, and does not function optimally. Take a look at NHS Heroes online pharmacy There can actually be several causes for cardiomyopathy, one of which is viral infections.

Individuals are usually diagnosed with one of the following two types:

  • “Primary” myopathy, which is attributed to a specific cause in the body, such as heart valve disease or a hereditary heart defect.
  • Secondary myopathy is related to diseases which involve other organs. The heart muscle becomes enlarged, thick or rigid and in more rare cases, muscles gets replaced with scar tissue.
As cardiomyopathy becomes worse the heart becomes weaker.It is not able to pump enough blood throughout the body to support a normal electrical rhythm. This leads to congestive heart failure, and arrhythmias (irregular heart rhythms).

As the muscle becomes weaker other severe complications can arise, such as heart valve problems.

At this time physicians believe that the majority of people who suffer from cardiomyopathy do so as a result of a complication of coronary artery disease (CAD). As you may know, CAD happens when the arteries that delivers blood to the heart muscle itself becomes blocked. The blockages cause a decrease in oxygenated blood that is delivered to the heart muscle which then leads to damage to the muscle and some scarring.

The majority of people who suffer from cardiomyopathy as the result of coronary artery disease are over the age of 65. However, about 50,000 people in the United States suffer from cardiomyopathy as a result of other conditions, and most of these people are younger.

There are four general types of cardiomyopathy.

  • The first is dilated cardiomyopathy and is the most common form. This happens when the heart muscle weakens, and as the muscle relaxes, the chambers expand. Approximately 30% of these cases are genetic (inherited) and the rest are a result of coronary artery disease.
  • The second type of cardiomyopathy is hypertrophic. This condition happens when the wall of the heart becomes thicker and it prevents blood from flowing through the heart. This condition is fairly rare and physicians and researchers are still not sure why it happens.
  • The third type of cardiomyopathy is restrictive cardiomyopathy. This happens when the walls of the heart becomes stiffer and do not relax enough to allow the heart to fill with blood. This reduces the efficiency of the pump.
Researchers have found that the most common cause of restrictive cardiomyopathy occurs when starch-like proteins (called “amyloid proteins”) build up in the heart muscle or as a result of  a hereditarydisorder in which iron salts are deposited in the tissues (called “haemochromatosis”).
  •  The fourth class of cardiomyopathy is arrhythmogenic right ventricular dysplasia(ARVD). This is a very rare form of cardiomyopathy, and is an inherited disease.
In this type, a person’s right ventricle is gradually replaced by a layer of fatty tissue. The most common result is cardiac “sudden death” in which the heart stops beating.  ARVD accounts for 1/5 of all cases of cardiac sudden death in people younger than 35.In fact, it is the leading cause of sudden death in young athletes.Unfortunately, not a lot is known about the disease and physicians estimate that somewhere between 30 and 90% of all cases are inherited. Some people who have cardiomyopathy show no signs or symptoms, and do not need treatment.  Others experience a very fast development of the disease, and the symptoms are severe.
  • Treatments for cardiomyopathy will include lifestyle changes, medications, implanted devices to correct the arrhythmias and nonsurgical procedures.
  • The goal of  treatment is to control symptoms, reduce complications and halt the progression of the disease.
Major risk factors include:
  • A family history of cardiomyopathy or heart failure
  • A disease or condition that can lead tocardiomyopathy, such as diabetes or obesity.
  • Diseases such as sarcoidosis (enlargement of lymph nodes) or amyloidosis (a build up of the starch-like protein mentioned above), long-term alcoholism or long-term high blood pressure.
The signs and symptoms of cardiomyopathy are often the same as heart failure. They include:
  • Shortness of breath or trouble breathing
  • Fatigue
  • Swelling in the ankles, feet or abdomen.
Other signs can include those which are related to a lack of oxygen delivery to the brain or muscles, such as:
  • light-headedness
  • dizziness
  • arrhythmias (abnormal heart rhythms)
  • heart murmurs
  • chest pain.
If you believe that you or anyone you know or love has these symptoms it is important to see your primary care physician or cardiologists as soon as possible.By addressing the underlying cause of the cardiomyopathy and resulting heart failure, as well as starting early treatment and medications, many people are able to lead a productive lifespan.
