OME/Cardio/Cardiomyopathy Flashcards
What physiologically happens in a dilated cardiomyopathy
The heart chamber(s) of the heart get stretch to the point were the actin/mysoin overlap is small
What type conditions can lead to a dilated cardiomyopathy?
Any condition that leads to an increase of blood with chamber ischemia, valve, dz, infection, metabolic or idiopathic
What can a Cardiomyopathy lead to?
Heart failure (similar signs/symptoms)
What is the Tx for dilated cardiomyopathy
Same as heart failure due to (NYHA criteria)
Dilated cardiomyopathy can be diagnosed using?
X-ray (shows enlarged heart)
Hypertrophic cardiomyopathy is most commonly due to?
An autosomal dominant condition where the heart muscles become enlarged (hypertrophy)
hypertrophy vs hyperplasia
increase in size vs increase in numbers
What is the main concern with hypertrophic cardiomyopathy?
An enlargement of the septum that blocks aortic
output->sudden death
Hypertrophic cardiomyopathy is common in?
Kids
What else should be check with an automomal dominant dz?
first degree relatives of pts with automomal dominant dz
Tx for hypertrophic cardiomyopathy
Tx like heart failure:
1-Beta blockers ( allows for ventricle to fill more and free aortic opening)
2-No exercise to avoid dehydration
Ablation (tissue removal)
What is a happens restrictive cardiomyopathy?
A condition where the heart muscles can not relax to let ventricle fill
Common causes of restrictive cardiomyopathy
1-Deposits from:Amyloid/sacroidosis/hemochromotosis
2-cancer/fibrosis (MI)
What is a cardiomyopathy?
Abnormality of the heart muscles
What types of cardiomyopathy exist?
Dilated (muscle has poor contraction)
Hypertrophic (muscle to big)
Restrictive (muscle can relax)
