Why does infective endocarditis cause anemia and how clubbing of finger nail associated near that?

The anaemia that occurs next to infective endocarditis is not haemolytic. Instead, it is the normocytic (normal sized) normochromic (normal coloured) anaemia associated with chronic disease. In this overnight case, it occurs because near is an established infection.
Like the anaemia, clubbing of the fingernails is associated with prolonged infective endocarditis. We aren't entirely sure almost the mechanism bringing up the rear it. What we do know is that it relates to increasing blood flow in the clubbed nouns, and that is credible due to dilation of the blood vessels here. No one can really agree as to why this happens.
anemia is cause by hemolysis of red blood cells(haemolytic type of anemia) the clubbing is a late sign contained by the sub acute presentation but i don't know why it happen
