Congestive Heart Failure Flashcards
Peripartum Cardiomyopathy risks:
age > 30
multiparity
African descent
hx of eclampsia, preeclampsia, post partum htn
maternal cocaine use, > 4 wks tocolytic rx with b agonists
Peripartum Cardiomyopathy treatment:
optimize hemo
avoid ace
hydralazine drug of choice
anticoagulate
HIV cardiomyopathy:
not receiving HAART, 17% incidence in Rowanda
cmv in late stages- also direct hiv, coxsackie and ebv
30% reduction in hiv cm with HAART rx
etoh cardiomyopathy
80-90 gm etoh/d
1 liter wine, 8 beers/d 1/2 pt liquor
less fibrosis, better prognosis
Hemochromotosis
MRI T2
dm, arthritis, hyperpigmented
thalassemia transfusion
treat phlebotomy, chelation
Antracycline induced CM:
dose > 550 mg/m2 higher incidence than < 1 yr after exposure, but up to 10 yrs
associated with radiation, dm, htn, poor nutrition
attenuate/ prevent with ace, carvedilol, dexrazoxane
MM dystrophies, cardiomyopathies
types
Duchenne’s (dystrophin absent) myopathy more severe
beckers - abnormal dystrophin so myopathy less, but cardiomyopathy worse
dystrophin- in sarcolemmal membrane
Stress Cardiomyopathy
chf incidence
rx
recurrence
Takotsubo
post menopausal women
16% chf, pul edema- card shock 10%, trigger emotional stress
rx supportive- anticoag, ace, b blocker
recurrence <4% mortality 1.7% in hospital
Hypertrophic CM rx
avoid vol depletion
activity limit
avoid ionotropes, sauna, etoh
rx b blocker, or verap/dilt/ disopyramide, myectomy
ICD: arrest, sustained vt/vf (consider if fhx, >30mm, nsvt, syncope hx, bp fall with exercise
giant cell myocarditis
T cell mediated
rapid progressive, often fatal
rx thymoglobulin, corticosteroids, calcineurin inhib.
may be associated with other autoimmune dx
chagas dx
typannosoma cruzi portal of entry - chagoma fevers, hepatosplenomegaly, myocarditis worse with worse heart function rx nitrofurtimox in acute phase, chronic may benefit antiparasitic rx
Lyme disease cardiac disease hallmark card effects vector: cause, dx, rx
erythema migrans, joint involvement, meningoencephaltis
carditis: palpitations, conduction abnl, myocarditis, lv failure
vector: black legged tick
bacterium Borrelia burgdorferi
serologies: IgM positivity rx iv ceftriax if card involvment
Lupus card effects
systolic or diastolic dysfunction
conduction delays
bx shows mononuclear cell
Hypersensitivity myocarditis
clinical
causes
fevers, rash, peripheral eosinophilia- rx remove agent, corticosteroid
med induced: hctz, furosemide, amp, tetracycline, methyldopa, azithromycine, aminophylline, phenytoin, benzo, tca
Myocardial and celiac disease/ rx
5% of celiac pts have myocarditis
improves with gluten free diet
