Why does hemochromatosis cause cardiomyopathy?
Iron overload cardiomyopathy is defined as systolic or diastolic cardiac dysfunction caused by increased deposition of iron and emerging as an important cause of congestive heart failure because of the increased incidence of this disorder seen in thalassemic patients and in patients with hereditary hemochromatosis [1].
Is hemochromatosis an infiltrative disease?
The most common hepatic storage diseases are fatty infiltration, hemochromatosis, Wilson disease, and glycogen storage diseases. Rare hepatic storage diseases are Gaucher’s disease and amyloidosis.
Does hemochromatosis cause cardiomyopathy?
Cardiac hemochromatosis or primary iron-overload cardiomyopathy is an important and potentially preventable cause of heart failure. This is initially characterized by diastolic dysfunction and arrhythmias and in later stages by dilated cardiomyopathy.
Is infiltrative cardiomyopathy hereditary?
Infiltrative cardiomyopathies are characterized by abnormal accumulation or deposition of substances in cardiac tissue leading to cardiac dysfunction. These can be inherited, resulting from mutations in specific genes, which engender a diverse array of extracardiac features but overlapping cardiac phenotypes.
Can hemochromatosis cause tachycardia?
Cardiac hemochromatosis can cause heart failure and cardiac arrhythmias. Among these arrhythmias, ventricular tachycardia may be resistant to treatment.
What is infiltrative process?
Infiltrative is a word pathologists use to describe the movement of cancer cells from their normal location into the surrounding non-cancerous tissue. Another word for infiltrative is invasion.
What is an infiltrative liver disease?
It is customary and useful to categorize liver diseases into three broad categories: Hepatocellular, in which primary injury is to the hepatocytes; cholestatic, in which primary injury is to the bile ducts; and infiltrative, in which the liver is invaded or replaced by non-hepatic substances, such as neoplasm or …
What are the 5 main types of cardiomyopathy?
Types of cardiomyopathy include:
- Dilated cardiomyopathy.
- Hypertrophic cardiomyopathy.
- Restrictive cardiomyopathy.
- Arrhythmogenic right ventricular dysplasia.
- Unclassified cardiomyopathy.
