Flashcards in Cardiomyopathy Deck (10):
1

What types of cardiomyopathy are there?

Hypertrophic
Dilated/congestive
Restrictive

2

What occurs in hypertrophic cardiomyopathy?

Excessive hypertrophy of ventricle wall & thick IV septum
Increase in wall size and dec in chamber size leads to decrease blood volume

3

What is the etiology of hypertrophic cardiomyopathy?

50% genetic (autosomal dominant)
50% idiopathic

4

What are the manifestations of hypertrophic cardiomyopathy?

Dyspnea
Angina
Syncope
Palpitations
Sudden cardiac death (overwork)

5

What is the treatment for hypertrophic cardiomyopathy?

Negative inotrope to decrease force of contraction and workload on heart
Alcohol septal ablation

6

What occurs in dilated/congestive cardiomyopathy?

Enlargement of atrium and ventricles, but especially V
The decreased elasticity in the heart results in weak contractions and a decreased ejection fraction

7

What is implicated as a cause for dilated/congestive cardiomyopathy?

Alcohol abuse

8

What occurs in restrictive cardiomyopathy?

The V walls are rigid leading to incomplete filling and a dec CO

9

What does restrictive cardiomyopathy lead to usually ?

CHF

10

What is cardiomyopathy?

Heart muscle disorder
