cardio 5 Flashcards
(22 cards)
who gets dilated cardiomyopathy
middle age (black, men, obesity, sleep apnea)
time of dilated cardiomyopathy
symptoms show up gradually; have be going on for years
prognosis of dilated cardiomyopathy
treatable but non reversible
top causes of dilated cardiomyopathy
viral, ischemic heart disease, alcoholism
what type of dilated cardiomyopathy is takotsubo syndrome
non-ischemic dilated cardiomyopathy
features of takotsubo syndrome
- acute systolic dysfunction of LV mimicking MI but in the absece of obstructive coranary artery disease or plaque rupture
- territory perfused by single caronary artery
cause of takotsubo syndrome
severe emotional or physical stress
management of dilated cardiomyopathy
ace/arb, bb carefully, spironolactone
when is an AICD indicated
when EF less than 75%
what effects do ANP and BNP posess
decrease HTN, increase water and sodium excretion
bnp- protects against fibrosis of the heart
features of hypertensive cardiomyopathy
appropriate symmetrical hypertrophy
is hypertensive cardiomyopathy systolic or diastolic dysfunction
primarily diastolic but later systolic
prognosis of hypertensive cardiomyopathy
treatable and reversible
cause of hypertensive cardiomyopathy
AS or HTN
triad of aortic stenosi
chest pain, heart failure, syncope
features of hypertrophic cardiomyopathy
innaproparite hypertrophy of LV; asymmetric involving septum
is hypertrophic cardiomyopathy systolic or diastolic dysfunction
BOTH which can occur at rest or not
prognosis of hypertrophic cardiomyopathy
treatable but nonreversible; genetic condition (autosomal dominant) resulting in mutated protein at the sarcomere
what should be recommended if you find hypertrophic cardiomyopathy
echo for first degree relatives
microscopic features of hypertrophic cardiomyopathy
disarray of myocytes, extreme hypertrophy of myocytes, interstitial fibrosis
what is hypertrophic cardiomyopathy often associated with
abnormal mitral valves that has messed up leaflets, anterior sticks during systole, or abnormal connections to papillary muscles
features seen in obstructive hypertrophic cardiomyopathy
obstruction of outflow of blood at rest due to septal hypertrophy and hyper-contractility
