Cardiomyopathies Flashcards

1
Q

On a routine echo, you notice that your patient has a dilated LV, rounded heart, decreased endocardial systolic motion, a large LA, and RV dysfunction. What is your diagnosis? What is the underlying etiology?

A 
Dilated Cardiomyopathy
Idiopathic (50%)
Myocarditis
Ischemia 
Chemo agents

Q

A pt presents with a mid-systolic harsh murmur that worsens with valsalva. An echo shows RVH and LVH. What diagnosis do you suspect? What treatment should you recommend?

A

Hypertrophic Cardiomyopathy
B-blockers (1st line)

Q

A pt present with a mid-systolic murmur that worsens with valsalva. He has arrhythmias and diastolic dysfunction. You suspect hypertrophic Cardiomyopathy which is confirmed with an Echo. What risk are you most worried about?

Q

A pt presents with arrhythmias and diastolic dysfunction. Echo shows signs of hypertrophic Cardiomyopathy. What is the most likely etiology of this disease?

A

Genetic (60-70%) - sarcomere protein mutation
Acquired - HTN, aortic stenosis
LVH, concentric/Apical hypertrophy, normal/reduced LV volume

A

Takotsubo (Stress-Induced) Cardiomyopathy

17
Q

A 35 yo African American woman presents with her 6 mo old son to the ER. Last month she was treated for heart failure and today her BP is 160/95 despite being on lisinopril and esmolol. What cardiomyopathy could this be? What is her prognosis?
