Flashcards in Cardiomyopathy Deck (10):
What types of cardiomyopathy are there?
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
What is the etiology of hypertrophic cardiomyopathy?
50% genetic (autosomal dominant)
What are the manifestations of hypertrophic cardiomyopathy?
Sudden cardiac death (overwork)
What is the treatment for hypertrophic cardiomyopathy?
Negative inotrope to decrease force of contraction and workload on heart
Alcohol septal ablation
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
What is implicated as a cause for dilated/congestive cardiomyopathy?
What occurs in restrictive cardiomyopathy?
The V walls are rigid leading to incomplete filling and a dec CO
What does restrictive cardiomyopathy lead to usually ?
