Cardiomyopathies and Myocarditis Flashcards
What is a group of a diseases that primarily affect the heart muscle and are not the result of congenital, acquired valvular, hypertensive, coronary arterial, or pericardial abnormalities?
Cardiomyopathies
What different morphological types of Cardiomyopathies are there?
Dilated
Restrictive
Hypertrophic
How many cases of heart failure are due to Dilated Cardiomyopathy?
40%
What is impaired and leads to remodeling with progressive dilation in Dilated Cardiomyopathy?
One or both of the ventricles’ systolic function
When do symptoms of Heart failure typically appear?
After remodeling
How many people inherit dilated cardiomyopathy from their parents?
1/3
T/F: Findings of narrow pulse pressure and elevated jugular venous pressure, S3 and S4 may be present due to reduced ventricular compliance
True
What age group is most commonly effected with Dilated Cardiomyopathy?
3rd-4th decade
What condition is caused by a mutation in some of the genes in heart muscle proteins, can develop over time due to high blood pressure/aging, and is usually inherited?
Hypertrophic Cardiomyopathy
What are the 3 key clinical features of Hypertrophic Cardiomyopathy?
Asymmetrical LV hypertrophy
Thickened septum
Hypertrophy of the apex
What is the first manifestation of Hypertrophic Cardiomyopathy?
Sudden Cardiac Death
What is the key symptom of Hypertrophic Cardiomyopathy and is due to impaired ventricular filling that occurs from diastolic ventricular failure?
Dyspnea
What condition results in the ventricle fails to relax fully, is excessively rigid which impedes filling (decreased compliance) eventually leading to diminished systolic capacity?
Restrictive Cardiomyopathy
What disease can cause Restrictive Cardiomyopathy in which too much iron builds up in the body?
Hemochromatosis
What disease can cause Restrictive Cardiomyopathy and causes inflammation and can affect various organs in the body and may have tiny lumps of cells to form in the body’s organs?
Sarcoidosis
