Cvs Flashcards
Infective endocarditis caused by micro-organisms affecting ……
Chambers, valves(native/prosthetic), blood vessels, congenital anomaly
Types of infective endocarditis
Acute
Subacute
Subacute infective endocarditis caused by ……………… when there is ………………… heart
Streptococcal
Diseased(valvular heart disease:rheumatic heart disease, mitral prolapse, aortic calcification, mitral regurgitation, prosthetic valve
Congenital heart disease; VSD
Idiopathic
The fatality of infective endocarditis increase when…………
1.there is prosthetic valve endocarditis
2. Infection with antibiotics resistence organism
Does IE (infective endocarditis) increase with age?
Yes, more than 50% of pts are over 60yrs
Infection with highly virulence organism such as ……………… can induce endocarditis in a previously normal heart which cause ………….. endocarditis.
Staphylococcus aureus, Acute
IE typically occur at sites of pre-existing ……………
Endocardial damage
Areas of endocardial damage caused by high pressure jet such as
VSD, mitral regurgitation, aortic regurgitation
Vegetation of IE made of
Platelete, fibrin, micro-organism
Vegetation of IE can cause
- Obstruction
- Abcess
3.emboli
4.valve regurgitation - Cusp perforation and chordae disruption
Extra cardiac features of IE
Vasculitis and skin lesion, emboli (lung, spleen,kidney) or immune complex deposition( glomerulonephritis, skin)
Mycotic aneurysm
Clinical features of subacute infective endocarditis
Fever, wt loss, night sweat, unusual tiredness, new sign of valvular dysfunction or heart failure, embolic stoke and peripheral arterial embolism, purpura petechia , splinter hemorrhage, osler nodes, CLUBBING, spleen and liver enlarged, microscopic HEMATURIA
Clinical features of acute infective endocarditis
CHANGING MURMURS and petechiae , embolic event, cardiac and renal failure, abscess, no sign of chronic endocarditis
Clinical dx of IE
2major
1 major+ 3 minor
5 minor criteria
Investigation of IE
Culture
Echo
Cbc (anemia, thrombocytopenia, leukocytosis)
Esr elevated but CRP more accurate fpr prognosis
Hematuria and proteinuria
ECG AV block assessment
CXR
Management of acute IE
Amoxicillin + vancomycin/ gentamycin
In prosthetic valve add rifampcin
Management of subacute endocarditis
Antibiotics should be witheld till results of culture came back
Acute pericarditis definition
Acute inflammation of pericardium -/+ pericardial effusion can occur as an isolated clinical problem or systemic manifestation
Dx of pericarditis( presence of 2 out of 4)
1.chest pain
2. Pericardial friction rub
3.ECG( PR depression, diffuse concave ST segment elevation without reciprocal changes, electrical alternans)
4.pericardial effusion
Arrhythmia occur in pericarditis
True but rare
Lab results of pericarditis
Elevated CRP
Leukocytosis
Elevated CK, CK-MB and troponin
Complication of pericarditis
Pericardial effusion
Cardiac tamponade
Recurrence
Constrictive pericarditis
CT findings of pericarditis
Pleural thickening
Calcified percardium
Ddx of ST elevation
Pericarditis
STEMI
Early repolarization
Myocarditis
Aneurysm
Burgarda
