The heart is the internal organ that is most affected by MRSA.
If MRSA is left untreated the MRSA infection can get into your bloodstream and when the MRSA gets into your bloodstream it can affect your heart.
If you do leave MRSA untreated and do not get medical treatment soon enough then you could have a heart attack, stroke and even death can occur.
MRSA is a serious condition that needs prompt medical treatment to prevent death.
Most commonly though if you get treated for MRSA a skin infection is all that usually happens.
But the longer you wait to get treated for MRSA the less chance you have at survival of the MRSA.
MRSA that is left untreated can lead to Sepsis and also endocarditis.
