CHF/Cardiomyopathy (19%) Flashcards
ABIM-CD Cardiology Recert.
What is the first line medical treatment for lupus myocardiits?
Systemic glucocorticoids
many would also add cyclophosphamide to steroid therapy
What medication to add to HFfEF patient with EF<35% on maximally tolerated b-blocker and other GDMT and has resting HR >70bpm?
Ivabradine
funny current in SA note inhibitor
Which medical condition from physical finding?
prominent v wave with a sharp y descent.
Tricuspid regurgitation.
The pressure is transmitted back to the atrium, causing a giant c-V wave (called the Lancisi sign)
HFrEF, class II or III, tolerating ACE or ARB, what medication is recommended( (Class I)?
valsartan/sacubitril
Reduces morbidity and mortality.
PARADIGM-HF trial.
Stop ACEi 36hrs prior to starting valsartan/sacubitril
ARNI=angiotensin receptor-neprilysin inhibitor)
What medical condition from physical finding?
elevated systemic venous pressure with sharp y descent Kusmaul sign and pericardial knock?
Constrictive pericarditis
the rapid y suggests rapid ventricular filling (so, constrictive pericarditis or restrictive cardiomyopathy), but 50% of patients with constrictive pericarditis have a pericardial knock (not seen in rcm).
Which trial?
ICD use for primary prevention is more effective in NYHA Class II than in patients with NYHA Class III.
SCD-HeFT
S/P orthotopic heart transplant distantly (over 1 year), presenting with CHF symptoms, LBBB, and low EF with regional wall motion abnormality. What is most likely diagnosis?
allograft vasculopathy.
rejection is generally earlier ~6-12 months
CHF, darker complexion despite not going outside much, DCM, normal coronaries, hepatosplenomegaly, diabetes diagnosed within past several months.
What unifying diagnosis?
Hemachromatosis
Hemachromatosis is Autosomal Recessive
Which trial?
Either continuous or bolus furosemide can be used to good effect in acute decompensated CHF.
DOSE study.
What is the drug of choice for beta-blocker toxicity?
Glucagon
stimulates cAMP through nonadrenergic pathways
What is the genetic characterization for HCM?
Autosomal Dominant (AD) Leads to altered or reduced amount of sarcomere protein.
What is the gene associated with autosomal dominant ARVC?
plakophilin-2
plakophilin-2, desmoglein-2, desmocolin-2, TMEM43
What is the gene associated with autosomal recessive ARVC?
Plakoglobulin and Desmoplakin
name for AR ARVC is Naxos Disease
What is the receptor associated with Catecholaminergic VT (CPVT)?
Ryanodine Receptor
Causes Calcium Overload, thus polymorphic VT
What is the most common genetic mutation for HCM?
MYBPC3 gene.
Mutation in the cardiac myosin binding protein C gene.
MY Binding Protein C
