<ul><li>With dilated cardiomyopathy, the muscle in the heart stretches and increases the size of the ventricular chamber, making it difficult for the heart to pump blood to the body.</li>
<li>Familial dilated cardiomyopathy occurs through many generations and accounts for up to 40% of peoplw with this condition.
</li><li> Symptoms for this condition are similar to congestive heart failure and may be difficult to treat.</li></ul>||<h2>What is dilated cardiomyopathy?<br></h2><p>Dilated cardiomyopathy is the most common kind of cardiomyopathy in both children and adults. It may be underreported because it is often not detected. </p><p>In dilated cardiomyopathy, the muscle in the heart becomes stretched, increasing the size of the ventricular chamber. This reduces the ability of the heart to contract, which in severe cases, results in not enough blood circulating to the body. When the ventricles do not squeeze the blood out of the heart, some blood can back up into the lungs. </p>

<p>Sometimes cardiomyopathy causes abnormal heart rhythms (arrhythmias) because the heart’s electrical impulse is not conducted properly through the stretched muscle. </p><h2>Causes of dilated cardiomyopathy</h2><p>When dilated cardiomyopathy occurs through many generations in a family, it is called familial dilated cardiomyopathy. About 30% to 40% of cases are traced to genes. The condition occurs more often in females than males, and in blacks more often than whites. </p><h2>Symptoms of dilated cardiomyopathy</h2><p>Symptoms are those typical of congestive heart failure: shortness of breath, tiring easily, difficulty tolerating physical exertion, fainting, sweating at rest, and sudden death. The heart will increase in size and the liver can enlarge. </p><h2>Treatment of dilated cardiomyopathy</h2><p>Children with dilated cardiomyopathy need intensive therapy. Symptoms can be challenging to treat. Children will usually need diuretics and angiotensin-converting enzyme (ACE) inhibitors, and some will be given beta blockers. In some cases, other procedures like implantable cardiac defibrillators (ICD) and ventricular assist devices, which help support cardiac output, may be used. This condition may require a heart transplant.</p>||Dilated cardiomyopathy|
