function
structure

Question 3

Functional classification:

3 types

Answer 3

1. dilated
2. hypertrophic
3. restrictive

impaired contractility and systolic function

Question 5

Functional classification:

sarcoid
hypothyroid
muscular dystrophy
hemochromatosis
hypertrophic
amyloid
idiopathic

Question 8

(Structural) types of cardiomyopathy that can present as either:

1. dilated cardiomyopathy w/ impaired systolic function OR
2. restrictive cardiomyopathy with impaired diastolic function

Answer 8

HTN
sarcoid
hemochromatosis
amyloid

Question 9

With decompensation,
cardiomyopathy that had features of:
1. functionally hypertrophic OR
2. restrictive

Answer 9

can begin to have features of dilated

(For instance, a patient whose problem was syncope due to arrhythmias may come to have dyspnea and other symptoms of heart failure)

Genetic differences can..

Answer 10

cause some family members to have hypertrophy,

while other members have dilatation

idiopathic dilated

[amyloidosis]
[hypertrophic]

Question 13

Answer 13

sarcoidosis

[amyloidosis]
[hypertrophic]
