inflammatory and valvular disease Flashcards
what is infective endocarditis
infection of the inner layer of the heart involving the cardiac valves or cardiac prosthesis. The pathogens get into the trabeculae of the muscles
who is at risk for developing infective endocarditis
rheumatic heart disease
congenital heat disease
mitral valve prolapse
cardiac surgery
invasive monitor or test such as angiograph
skin, bones or pulmonary infections
poor oral hygiene
IV drug abusers
immunosuppressive` state
What causes the infective endocarditis
staphylococcus aurea
viridians streptococci
enterococci
coagulase/negative staphyoccus
what are the types of endocarditis
Acute infective endocarditis
Subacute endocarditis
what is acute endocarditis
normal valves
rapid progressive
leads o systematic infection
causes sever valvular destruction
what is subacute endocarditis
damaged valves can cause regurgitation
insidious onset over period
outcome usually good with antibiotics
it can be life threating
longer clinical course
what is vegetations
its the growth or clumping on the valves filled with fibrin pathogens
what can happen with vegetation
the piece can break of and travel embolism
what happens if the vegetations embolism on the left side
it is located on the mitral valve and it would go systematically as blood flows
what is vegetation made of
fibrin
leukocytes
microbes
what causes the right vegetation growth
iv drug user
what are the causes of the left vegetation
usually bacterial infection
underlying heart disease
what happens when vegetations is on the right side
as blood flows it would go into the lungs respiratory failure
how can you suspect that somebody is drug abuser
by checking the forearms for scratches and bruising called tracks
