Study Notes
Cardiomyopathy
- Disease of the heart muscle (myocardium) that inhibits effective pumping
- Can lead to heart failure
Causes of Cardiomyopathy
-
Primary cardiomyopathies
- Start or develop on their own
- Often genetic
-
Secondary cardiomyopathies
- Caused by other conditions, such as high blood pressure or valve disease
- Any disease that leads to myocardial damage
Specific Causes of Cardiomyopathy
- Coronary artery disease
- Genetic mutations
- Autoimmune diseases, including connective tissue diseases
- Infections that affect the heart muscle
- Heart inflammation
- Diabetes
- Thyroid disease
- Muscular dystrophy
- High cholesterol
- Sarcoidosis
- Amyloidosis
- Hemochromatosis
Types of Cardiomyopathy
-
Dilated Cardiomyopathy
- Chambers of the heart dilate to compensate
- Leads to decreased ejection fraction and pumping ability
-
Restrictive Cardiomyopathy
- Heart becomes stiff and less able to stretch
- Decreases filling ability of the heart and ability of the heart to contract
-
Hypertrophic Cardiomyopathy
- Chambers of the heart hypertrophy to compensate
- Leads to decreased filling ability of the heart
Pathophysiology of Cardiomyopathy
- Thickening and disarray of the left ventricular myocardium
- Leads to decreased pumping ability
- Dilated chambers compensate by dilating
- Restrictive chambers compensate by becoming stiffer
- Hypertrophic chambers compensate by thickening
Complications of Cardiomyopathy
- Chronic heart failure
- Blood clots
- Chest pain
- Heart murmurs
Cardiomyopathy Definition
- Cardiomyopathy is a disease of the heart muscle (myocardium) that inhibits effective pumping, potentially leading to heart failure.
Causes of Cardiomyopathy
- Primary cardiomyopathies: Develop independently, often due to genetic factors.
- Secondary cardiomyopathies: Caused by other conditions like hypertension or valve disease, resulting in myocardial damage.
Specific Causes of Cardiomyopathy
- Coronary artery disease
- Genetic mutations
- Autoimmune diseases, including connective tissue diseases
- Infections affecting the heart muscle
- Heart inflammation
- Diabetes
- Thyroid disease
- Muscular dystrophy
- High cholesterol diseases
- Sarcoidosis
- Amyloidosis
- Hemochromatosis
Pathophysiology of Cardiomyopathy
- Dilated cardiomyopathy: Chambers of the heart dilate to compensate for decreased pumping ability, leading to lower ejection fraction and increased risk of blood clots.
- Hypertrophic cardiomyopathy: Heart muscle thickens, making it harder for the heart to fill with blood, resulting in decreased filling ability and heart murmurs.
- Restrictive cardiomyopathy: The heart becomes stiff, limiting its ability to stretch and fill with blood, reducing contractility.
Complications of Cardiomyopathy
- Chronic heart failure
- Blood clots
- Chest pain
