Which liver condition can cause restrictive cardiomyopathy and is treated with phlebotomy?

Hemochromatosis is a genetic disorder that leads to excessive absorption of iron from the diet, resulting in iron overload in various organs, including the liver. This increased iron can deposit in heart tissue, causing restrictive cardiomyopathy, which is a condition where the heart muscle becomes stiff and cannot properly fill with blood.

Phlebotomy, or the therapeutic removal of blood, is the primary treatment for hemochromatosis. By regularly removing blood, the body utilizes stored iron to replenish the lost blood cells, thereby reducing overall iron levels in the body and minimizing the risk of organ damage, including damage to the heart and liver.

Other conditions listed, such as hepatitis B, cirrhosis, and liver cancer, do not typically lead to restrictive cardiomyopathy caused by iron overload or are treated through phlebotomy. Hepatitis B is a viral infection that primarily affects the liver, cirrhosis is the result of chronic liver damage that leads to scarring, and liver cancer presents with different treatment modalities that do not involve phlebotomy.
