Q

What is Cardiomyopathy?

A

heterogeneous group of diseases

mechanical and/or electrical dysfunction of the heart

2
Q

2 ways of classifying cardiomyopathy

A
function
structure
3
Q

Functional classification:

3 types

A
  1. dilated
  2. hypertrophic
  3. restrictive
4
Q

Functional classification:

dilated cardiomyopathy

A

impaired contractility and systolic function

5
Q

Functional classification:

hypertropic cardiomyopathy

A

impaired compliance and diastolic function

6
Q

Functional classification:

restrictive cardiomyopathy

A

impaired compliance and diastolic function

7
Q

Structural classification:

12 types

A
ischemic
hypertensive
alcoholic
Adriamycin
peripartum
sarcoid
hypothyroid
muscular dystrophy
hemochromatosis
hypertrophic
amyloid
idiopathic
8
Q

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

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

HTN
sarcoid
hemochromatosis
amyloid

9
Q

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

A

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)

10
Q

Genetic differences can..

A

cause some family members to have hypertrophy,

while other members have dilatation

11
Q

Presentation of cardiomyopathies usually either…

A
  1. HF

OR

  1. arrhythmias
12
Q

Cardiomyopathies w/ HF presentation

A

idiopathic dilated

[amyloidosis]
[hypertrophic]

13
Q

Cardiomyopathies w/ arrhythmia presentation

A

sarcoidosis

[amyloidosis]
[hypertrophic]
