What causes of heart murmur?

Innocent heart murmurs
- Physical activity or exercise
- Pregnancy
- Fever
- Not enough red blood cells to carry oxygen (anemia)
- An increase in the amount of thyroid hormone (hyperthyroidism)
Abnormal heart murmurs
- In children the cause mostly due to structural problems of the heart (congenital heart defects). examples:
- Holes in the heart.
- Abnormal blood flow between the heart chambers or blood vessels(shunt)
- Heart valve abnormalities. Congenital heart valve abnormalities are present at birth, but sometimes aren't discovered until much later in life.
- In older children or adults causes of abnormal heart murmurs include infections or conditions that damage the structures of the heart for example:
- Hardening or thickening of valves, as in mitral stenosis or aortic valve stenosis, can occur as you age.
- Endocarditis. This infection of the inner lining of your heart and valves when bacteria or other germs lodge in your heart. endocarditis if left untreated can destroy your heart valves in people who already have heart valve abnormalities.
- Rheumatic fever. rare in the United States.
