Cardiac-Endocarditis Flashcards
what bacteria is the over all most common cause of endocarditis?
strep viridans
what is the significance of strep viridans being a “low virulence” organism
it only infects previously damaged valves and will not destroy the valve
what is the most common cause of endocarditis in IV drug users
staph aureus
can staph aureus destroy the valves?
yes because it is high virculence
what valve is staph most likely to infect?
tricuspid
staph epidermidis is the most common cause of endocarditis in..?
prosthetic valves
if you have a patient that has endocarditis due to strep bovis, what are you worried about
underlying colorectal cancer
what are the HACEK organisms?
- haemophilus
- actinobacillus
- cardiobacterium
- eikenella
- kingella
what are the HACEK organisms associated with?
endocarditis with negative blood cultures
what is the following describing:
“erythematous nontender lesions on palms and soles seen in peeps with endocarditis”
janeway lesions
what is the following describing:
“TENDER lesions on fingers and toes seen in peeps with endocarditis”
osler nodes (olser=OUCH..these are the painful lesions)
what are the anemic lab findings in a person with endocarditis: Hb MCV ferritin TIBC serum iron % sat
Hb- low MCV-low ferritin-high TIBC-low serum iron-low % sat-low
when do nonbacterial thrombotic endocarditis due to sterile vegetations arise? (2). where do these vegetations arise
hypercoaguable state or underlying adenocarcinoma
vegetations arise along lines of closure and result in mitral regurg
if you see vegetations on BOTH sides of mitral valve causing mitral regurg, what type of endocarditis are you thinkin
libman sacks endocarditis due to SLE
