Cardiomyopathy/pericardial disease Flashcards
physical exam findings of tamponade?
pulsus paradoxus, x descent on JVW, distant heart sounds, bottle shaped heart
complication of stress induced CM?
LVOT obstruction
management for stress induced CM?
BB, volume, and if pressors needed use pure alpha
treatment for resistant pericarditis?
immunosuppressants like azatioprine, anakinra
things that can cause restrictive CM?
sarcoid and carcinoid
constrictive pericardtisi JVW findings?
elevated JVP with prominent y descent
what happens to JVP during diastole in constrictive pericarditis?
collapse, this is not seen in tamponade
Kussmaul sign?
inc JVP with inspiration rather than expiration
thickness of pericardium in constrictive pericarditis?
5mm
diagnosis of cardiac amyloidosis?
serum light chains with monoclonal spike, biopsy, or bone scintography
ejection systolic crescendo decrescndo murmur at left sternal border?
HOCM
murmur of HOCM with squatting, handgrip?
squatting- inc, handgrip lessens
what is the cause of risk of death with HOCM?
long QT- debrillator
medications to treat HOCM?
BB or non dihydropyridine CCM like verapamil
if patient is not a surgical candidate in HOCM then what intervention should they have?
dual chamber pacing
what is the indication for surgery with HOCM?
outflow gradient of > 50 mmhg
HOCM surgery for the young? old?
myomectomy, alcohol ablation
pulsus paradoxus- what is it? what do you see it in?
decrease in systolic BP by 10 mmhg on inspiration/ tamponade
becks triad of tamponade?
muffled or absent heart sounds, hypotension, inc JVP
CVP waveform findings of tamponade?
prominent x descent and blunted y descent
pathologic findings of viral myocarditis?
lymphocyte infiltration and myocyte necrosis
management for pericarditis?
NSAID plus colchicine
possible cause and tx for acute eosinophilic myocarditis?
phenytoin, immunlogics
presentation of acute hypersensitivity eosinophilic myocarditis?
pink colored rash, eosinophilia, CHF,
