CMO Cardiomyopathy Flashcards
what is the most common CMO
dilated CMO
causes of dilated CMO
idiopathic
family history
valve heart disease
IHD
hypertension
infection
drugs and alcohol
signs and symptoms of Dilated CMO
decreased cardiac output
palpitations, syncope, dyspnea
chest pain
thrombus
effusion
dilated CMO on echo
thin walls
gross dilatation on the heart
smoke appearance of blood
possible thrombus in apex
dilated CMO on m mode
increased MV e to septal seperation
decreased MV excursion
MV double diable
B notch due to increased pressures
hypertrophic CMO etiology
idipathic
genetics
microscopic disorganized fibers of the myocardial
type of hypertrophic CMO
- asymmetric septal hypertrophy
- concentric hypertrophy
- mid ventricular hypertrophy
- provocable
- non obstructive (apical hypertrophy)
hypertrophic CMO symptoms
DYSPNEA ON EXERTION!
nocturnal dyspnea
CHEST PAIN ESPECIALLY WITH EXERCISE
PALPITATIONS
WHICH TESTING IS THE GOLD STANDARD TO ASSESS AND DIAGNOSE HCMO
