Familial Dilated Cardiomyopathy
Terms in this set (14)
Familial Dilated Cardiomyopathy
A genetic heart disease in which the heart is enlarged with a larger pumping chamber and thin walls. This causes the heart to be unable to pump blood efficiently
What can happen if you have dilated cardiomyopathy?
1. The heart is unable to supply the body with enough blood
2. Blood clots can form
4. Might obtain arrhythmias
6. Swelling of the legs
7. Shortness of breath
Irregular heart beats and rhythms
What is the life expectancy of someone with dilated cardiomyopathy?
The life expectancy is limited, the approximate survival time is about 5 years after one is diagnosed. This disease has a survival rate of less than 50% in ten years.
How does the heart deal with dilated cardiomyopathy?
The heart attempts to increase the blood thats being pumped which cause the walls to become even thinner and weaker. This may result in heart failure.
When does this condition start affecting the person?
It takes years for symptoms to cause health problems. It presents itself during mid-adulthood, rarely childhood. Its good if the condition is caught early.
How many people in the US have dilated cardiomyopathy?
How many are familial?
Approximately 750,000 people in the United States have dilated cardiomyopathy.
Almost half of these cases are familial.
What causes dilated cardiomyopathy?
Mutated genes are shown to be a cause of this disease. They give instructions for making proteins which are found in cardiac muscle cells, cardiomyocytes. Mutations in TTN account for a percentage for the causes of familial dilated cardiomyopathy. However, scientists/doctors have not found a direct cause to how this disease occurs, it is unclear how mutations affecting other genes and protein cause this.
Other causes for dilated cardiomyopathy
Dilated cardiomyopathy may occur in only one family member and then spread. For a family member to acquire this disease it may be because of the following reasons:
Diseases that affect the arteries of the heart (due to smoking, high cholesterol, genetics and other factors)
Hypertension (high blood pressure)
Infected heart muscles
Medicine toxic to the heart
Heart Valves that are infected (their diseases) which may be present during birth or due to age, infection and more
Are there genetic reasons as to why dilated cardiomyopathy was caused?
Yes there are, this can include chronic alcohol abuse, poorly controlled high blood pressure and viral infections.
What are the symptoms of dilated cardiomyopathy?
In some cases patients may not be symptomatic.
In other cases the first symptom may be death.
With most cases, symptoms may include fatigue, shortness of breath, nausea, problems with their chest (chest pressure, chest pain), dizziness and more.
Is there a treatment?
Treatment of patients with dilated cardiomyopathy is personalized to fit their needs depending on their symptoms
People who are symptomatic are given combinations of medications
Patients who are asymptomatic may take beta blockers or ACE inhibitors to prevent the progression of the disease.
Enlarged left ventricle due to dilated cardiomyopathy
Walls have become thinner
