Does limb girdle muscular dystrophy affect the heart?

The heart can be affected in LGMD, but this does not occur as often as it does in some other forms of muscular dystrophy. Heart problems can take two forms — weakness of the heart muscle (cardiomyopathy) and abnormal transmission of signals that regulate the heartbeat (conduction abnormalities or arrhythmias).

Can muscular dystrophy affect the heart?

Both the Duchenne and Becker forms of muscular dystrophy are associated with a heart condition called cardiomyopathy. This form of heart disease weakens the cardiac muscle, preventing the heart from pumping blood efficiently.

Why would muscular dystrophy affect cardiac function?

The heart muscles become progressively fibrotic, leading to heart arrhythmias and eventually cardiomyopathy. In Becker muscular dystrophy (BMD), nearly 40 percent of patients may be diagnosed with dilated cardiomyopathy where the left ventricle becomes enlarged and thin, and cannot pump blood properly, by age 30.

Can CHF cause muscular dystrophy?

Core tip: Duchenne and Becker muscular dystrophy are the commonest X-linked muscular diseases. Death is usually due to cardiac disease including ventricular dysfunction, heart block or malignant arrhythmias. Female carriers may also present cardiac involvement. Overt heart failure may be delayed or absent.

Is limb-girdle muscular dystrophy fatal?

Limb-girdle muscular dystrophy For others, disease progression is slow and may not affect life expectancy. Current research indicates that the age of onset of the disease may be predictive of how rapidly the disease will progress, with patients showing symptoms in childhood being the most severely affected.

How long can you live with limb-girdle muscular dystrophy?

The person may be dependent on a wheelchair within 20 to 30 years. Heart muscle weakness and abnormal electrical activity of the heart can increase the risk for palpitations, fainting, and sudden death. Most people with this group of diseases live into adulthood, but do not reach their full life expectancy.

What is the life expectancy for someone with muscular dystrophy?

People with Duchenne muscular dystrophy typically require a wheelchair before their teenage years. The life expectancy for those with this disease is late teens or 20s.

Does muscular dystrophy qualify for disability?

People who suffer from muscular dystrophy may qualify for SSDI benefits under the SSA’s listing for the diseases. However, these individuals must prove that the symptoms and complications outlined in the SSA’s disability listing exist. Disorganization in muscle function is one of these requirements.

Does muscular dystrophy affect the brain?

The molecular missteps that disrupt brain function in the most common form of adult-onset muscular dystrophy have been revealed in a new study. Myotonic dystrophy is marked by progressive muscle wasting and weakness, as well as sleepiness, memory problems, and mental retardation.

How long can you live with muscular dystrophy?

In its most common form, Limb-girdle muscular dystrophy causes progressive weakness that begins in the hips and moves to the shoulders, arms, and legs. Within 20 years, walking becomes difficult or impossible. Sufferers typically live to middle age to late adulthood.

Who carries the gene for muscular dystrophy?

Inheriting muscular dystrophy. You have two copies of every gene (with the exception of the sex chromosomes). You inherit a copy from one parent, and the other copy from the other parent. If one or both of your parents has a mutated gene that causes MD, it can be passed on to you.

What is the life expectancy of someone with limb-girdle muscular dystrophy?

How are limb girdles related to muscular dystrophy?

Collectively, these are called the limb girdles, and it is the observed weakness and atrophy (wasting) of the muscles connected to the limb girdles that has given this group of disorders its name.

Which is more common LGMD or cardiomyopathy?

Patients with the autosomal dominant form of limb-girdle muscular dystrophy (LGMD) are more prone to arrhythmias and conduction issues rather than cardiomyopathies. While types 2A and 2B LGMD are not associated with significant heart complications, cardiomyopathy is common in type 2C LGMD patients with low incidence rates of arrhythmias.

How does LGMD affect a person’s heart?

People whose LGMD has reached this stage often find that a great deal of their independence returns, and they are much less fatigued, when they begin using this type of vehicle. The heart can be affected in LGMD, but this does not occur as often as it does in some other forms of muscular dystrophy.

How is LGMD Like other muscular dystrophies?

There are devices that can help sustain respiratory function. LGMD, like other muscular dystrophies, is primarily a disorder of voluntary muscles. These are the muscles you use to move the limbs, neck, trunk and other parts of the body that are under voluntary control.
