Myocarditis Flashcards
what heart disease is charaterized by abnormal heart muscle not from CAD, HTN, Valve disease, or CHD?
cardiomyopathies
what is the most common cardiomyopathy, and its cause
dilated, idiopathic
inability to contract and expel blood is a ____ side heart problem, while cor pulmonale is a ____ side heart problem
Left, Right
heart disease associated with enlarged atria
Cardiomyopathy
what disease has LV cavity increases with not HTN or Hypertrophy and has endocardial fibrosis
Cardiomyopathy
what are the ABCDPIG causes of Dilated CM
Alcohol, beri beri, Cox, Drugs, Pregs, Idiopathic, genetic
Most common cause of dilated cardiomyopathy, and thus most common cause of HF due to systolic dysfunction. LVEF<35% from CAD
Ischemic CM
Treat this disease with ASA, statins, beta blockers, ACE, Loops, and K-sparring diuretics
Ischemic CM
associated with Acetaldehyde damage, leads to prolonged QT.
alcoholic CM, abstain
what disease has HF late in pregnancy (within 1 month of birth)
Peripartum Cardiomyopathy
when can you wean a patient with perpartum CM off therapy
LVEF>50%
Broken heart syndrome with systolic apical ballooning
Takotsubo
what CM leads to a troponin level 7x elevated, ST elevation, and with apical ballooning pattern
Takotsubo
Which CM has SXS of both LHF and RHF, with heaves and a shifted PMI
Dilated cardiomyopathy
What can you see in a CBC & CMP in Dilated CM?
CBC = anemia (high output state) CMP = hyponatriemia, LFTs, electrolyte inbalance
What can you see in a CXR, EKG, Cardiac Cath in DCM?
CXR = cardiomegaly, pulm congestion, Kerley B lines,
EKG = LVH, conduction delay, arrythmias.
Cardiac Cath = exclude ischemia
What disease do you treat like HF (Ace/Arbs, Beta blockers, aldostrone ant, Diuretics, Nitro, Sacubitril-valsartan)?
Dilated Cardiomyopathy.
If your patients has ischemic dilated CM what do you do?
Revascularization
How do ACE-I help DCM
reduce preload, afterload by vasodilation. Prevent cardiac remodeling.
What are the side effects of an ACE?
CHAA, Cough, hyperK, angio edema, acute nephritis
How do Beta blockers help DCM
In EF<40%, can reduce catecholamine effects and slow HR = increased filling time, while decreasing afterload. This allows better coronary perfussion.
When should you not give beta blockers to a patient with DCM
HR< 50, 2/3 degree heart block, asthma, COPD
What are surgical options for DCM
LVAD, cardiac resynchronization therapy if EF<35% or Bundle branch block on EKG.
most common cause of DCM
idiopathic
