non ischemic cardiomyopathy Flashcards
3 types of amyloid
Light chain - plasma cell dyscrasia
TTR - mutant protein transthyretin, AD transmission
Senile - elderly
increased LV size
decreasded LV ejection fraction
dilated cardiomypathy
in cardiomyopathy, sympathetic activation leads to > (4)
Increased HR
RASS Activation
Increased aldosterone
increased ADH
asymetric LV hypertrophy
typically in septum
possible LV outflow obstruction
hypertrophic cardiomyopathy
key exam finding of hypertrophic CM
harsh systolic murmur at left sternal border
indcreases in intensity with valsalva or when getting up
key physical exam findings dilated cardiomyopathy
S3 gallop
soft s1 (mitral closing)
key diagnostic clue for amyloid
low voltage ECG
right sided heart failure signs
depedent (pitting) edema
jugular venous distention
hepatomegaly
splenomegaly
ascites
anorexia
left sided signs of heart failrue
pulmonary congesstion
(rales, decreased breath soudns from pleural effusion)
small LV thick walls
filling problem
possible via infiltrative process
restrictive cardiomyopahty
cardiomyopathy vs heart failure
CM = abnormal myocardial tissues leading to structural heart disease
HF - signs and symptoms related to strutural heart disease, from inability to contract or fill
sx of heart failure
dyspnea on exertion
orthopnea (breathing while flat)
paroxysmal nocturia dysnea (waking)
lower extremity edema
ascites decreased apetite, nausea
weakness, fatigue
