23
Q

Endocarditis - what?

A

infection of endocardium

The infection often colonizes the valve – referred to as vegetation

24
Q

Who is at risk for developing endocarditis?

A
People who have had or have...
Prosthetic heart valve
Structural defect
Implantable device
Previous episode of endocarditis
Immunosuppression
Neutropenia
Malignancy
Intravenous drug use
Nosocomial hospital exposures
Central venous catheter
25
Q

What is infective endocarditis?

A

Pathogens can enter endocardium through dental or surgical procedures

26
Q

s/s infective endocarditis?

A

Fever & heart murmur will dev. W night sweats
Osler nodes
Janeway lesions
Roth spots
Splinter hemorrhage under nails
Petechiae on chest, abdomen conjunctiva and mucous membranes

27
Q

infective endocarditis treatment

A

Eliminate infection - culture needed

a. long term abx therapy (6m+)
- blood cultures needed to monitor fx of therapy
- serum blood levels of selected abx

b. long term IV access

28
Q

What is pericarditis

A

inflammation of pericardium

29
Q
