Question

describe the different between dilated, hypertrophic, and restrictive cardiomyopathy and what type of patient it might affect.

What are the differences and how would you as a nurse change your plan of treatment, tests, lab, medication, etc.?

What changes might you see in their EKG tracing, for these patient.

What is EF or ejection fraction? , How is this affected with their disease process?

What is BNP (B-type natriuretic peptide) what is the significance and the level.

Answer 1

#. Dilated hypertrophic cardiomyopathy :-

significant dilation of the ventricles without simultaneous hypertrophy- resulting in increased atrial and ventricular chamber size and decreased muscle size.

The condition affects people of all ages, including infants and children, but is most common in men ages 20 to 50.

Restricted cardiomyopathy :-

diastloic dysfunction caused by rigid ventricular walls that impair diastolic filling and ventricular stretch- leads to left ventricular hypertrophy.

It affects equally in males and females, average age of onset is 50

Hypertrophic cardiomyopathy :-

heart muscle assymetricly increases in size and mass, especially along the septum- results in thickened intervertricular septum, decreased ventricular chamber size, and left ventricular hypertrophy.

It is common in men under age 30.

#. EKG: nonspecific ST and T wave changes, LBBB.

#. Ejection fraction - percentage of the blood volume ejected out of the ventricles relative to the volume of blood recieved by the ventricles before contraction . EF is reduced( <40%) in cardiomyopathy because the heart can't pump blood effectively .

#. Brain Natriuertic peptide :-

Released by the ventricles of the heart in response to stretching of the heart muscle cells. Healthy range is less than 100 picograms of BNP per milliliter (pg/ml) of blood.
