Study Notes
- Cardiomyopathies are classified based on structural abnormalities and genotype
- Intrinsic cardiomyopathies involve disorders of the muscle itself
- Extrinsic cardiomyopathies are due to specific disorders such as CAD, hypertension, ischemia, or valvular dysfunctions
Hypertrophic Cardiomyopathy
- This cardiomyopathy involves a stiff, noncompliant muscle
- There is left ventricular(LV) hypertrophy, causing obstruciton to the aortic outflow tract
- Secondary mitral regurgitation(MR) occurs because of the "tug" on the papillary muscle
- Signs and symptoms include exertional dyspnea, ischemia, supraventricular tachycardia/ ventricular tachycardia (SVT/VT), syncope, and failure
- Treatments include limiting physical activity, beta blockers, antiarrhythmics, and anticoagulation
- For heart failure, diuretics, vasodilators, or ACE inhibitors may be needed
- Surgical treatments are available
Dilated Cardiomyopathy
- This cardiomyopathy is characterized by dilated ventricles without hypertrophic muscles
- The muscle fibers contract poorly
- This leads to low cardiac output, arrhythmias, and blood pooling
- Goals of treatment include improving pump function, controlling failure, and preventing death
- Treatments target symptom management to prevent symptoms of systolic heat failure(SHF)
- Other treatments include anticoagulants, beta blockers, diuretics, pacemakers, and surgery
Restrictive Cardiomyopathy
- This cardiomyopathy leads to abnormal diastolic function
- The ventricles become rigid and cannot fill
- This will lead to backward heart failure, liver engorgement, orthopnea, and dyspnea
- Symptomatic treatment involves hypertension control, diuretics, ACEs or ARBs, and exercise restrictions.
Nursing Considerations
- The bottom line of all cardiomyopathies is decreased cardiac output
- Nursing considerations include managing fluid balance and the many medications, as well as patients activities and ADLs(activities of daily living)
- Family involvement and education are important
