-itis: - Answer✔inflammatory
Endocardium - Answer✔Inner layer of the heart
Myocardium - Answer✔muscular, middle layer of the heart
Visceral pericardium - Answer✔layer closest to the heart
parietal pericardium - Answer✔outer layer of the pericardium
Endocarditis - Answer✔inflammation of the endocardium (inner lining of the heart)
Endocarditis often starts with ________. - Answer✔pathogens on the valves
- because blood can slow down at these areas and become stagnant causing potential for clots
and infection
Acute endocarditis - Answer✔Sudden, rapidly progressing marked onset—spiking fever, chills,
drowsiness
Subacute endocarditis - Answer✔Insidious onset, lasting several months —increasing fatigue,
anorexia, cough, and dyspnea
Rheumatic endocarditis - Answer✔-caused by acute rheumatic fever
-usually school aged children
-following group A beta hemolytic strep pharyngitis

2. streptococcus aureus
Risk factors of endocarditis: - Answer✔- IV drug use
- valve replacements
- systemic alterations in immunity
- structural cardiac defects
- during bacteremia (bacteria circulating throughout the systemic system, bacteria become
trapped in the low pressure "sinkhole" and are deposited on the vegetation)
How do you diagnose endocarditis? - Answer✔- echocardiograms: transesophageal echo (TEE)
for visualization og the posterior aspect of heart structures
- aerobic and anaerobic blood cultures
- 2 from2 dif sites
- peripheral stick not central lines
- may have low hematocrit and hemoglobin
S/S of endocarditis: - Answer✔- HF
- fever (99-103) with chills, night sweats, malaise
- weight loss
- **murmur
- petechiae (small flat lesions)
- **splinter hemorrhages on nail beds
- osler's nodes on palms and soles
- Janeway's lesions (hands and feet)
- systemic embolization-fragments of vegetation (clots)
Right-sided vegetation results in fragments carried to: - Answer✔- pulmonary circulation:
pleuritic chest pain, dyspnea, cough
Left-sided vegetation results in fragments carried to: - Answer✔- spleen: rebound tenderness on
palpation
- kidney: flank pain radiating to goin, hematuria, pyuria
- GI tract: mesenteric emboli (pain after eating), abdominal distention
Brain: neurologic changes (TIA or stroke), confusion, reduced concentration, aphasia, dysphagia
Complications of endocarditis - Answer✔- HF
