Study Notes
Cardiomyopathy Overview
- Cardiomyopathy is a disease of the heart muscle, leading to impaired heart function
Cardiomyopathy Types
-
Dilated Cardiomyopathy (DCM)
- Increased chamber size and reduced pumping ability
- Common causes include idiopathic, toxins, and hypertension (HTN)
- Symptoms include shortness of breath (SOB), edema, heart rhythm abnormalities, and valve problems
- Treatment focuses on managing heart failure (HF) with medications, implantable cardioverter-defibrillator (ICD), or heart transplant
-
Hypertrophic Cardiomyopathy (HCM)
- Thickened heart muscle, reduced chamber size, and restricted filling
- Often genetic in origin, also associated with HTN
- Symptoms involve heart rhythm issues, chest pain, and sudden death risk
- Management includes HF medications, surgical removal of excess muscle, and ICD
-
Restrictive Cardiomyopathy (RCM)
- Stiffened heart muscle with normal contractility
- Causes includes amyloidosis and fibrosis
- Symptoms include fatigue and right-sided HF signs
- Treatment centers on symptom management and addressing any heart failure
-
Arrhythmogenic Right Ventricular Dysplasia (ARVD)
- Fatty or fibrous right ventricle increasing arrhythmia risk
- Genetic predisposition with desmosomal mutations
- Symptoms include ventricular tachyarrhythmias and sudden cardiac death risk
- Management involves screening, medication, and surgical intervention
-
Transthyretin Amyloid Cardiomyopathy (ATTR-CM)
- Amyloid protein deposits within the heart leading to stiffness
- Can be inherited or occur spontaneously
- Symptoms can include HF-like signs and nerve damage
- Treatment uses tafamidis to stabilize the amyloid protein, and HF symptom management
-
Unclassified Cardiomyopathies
- Includes variations like left ventricular noncompaction and Takotsubo cardiomyopathy
- Causes can be stress-induced or structural anomalies
- Symptoms mimic heart failure or stress-related dysfunction, diagnosis depends on underlying condition
Cardiomyopathy Clinical Manifestations & Therapies
-
Heart Failure (HF)
- Symptoms include SOB, fatigue, edema, and abdominal fluid buildup
- Treatment involves medications like diuretics, vasodilators, beta-blockers, and calcium channel blockers, as well as monitoring and supportive interventions like fluid restriction and position changes
-
Dysrhythmias
- Irregular heart rhythms including supraventricular tachycardia, atrial fibrillation, and ventricular tachycardia
- Treatment through medications, ICD, and patient education about recognizing symptoms
-
Angina
- Chest pain radiating to jaw, arm, or back, often triggered by exertion
- Management with medications, coronary artery repair if needed, and patient education on symptom management and emergency response
-
Syncope
- Fainting, dizziness, lightheadedness
- Treatment involves beta-blockers and patient education on safety measures to prevent falls
Cardiomyopathy Diagnostic Tests
- Initial evaluation includes history and physical
- Key tests include echocardiography, electrocardiogram (ECG), chest x-ray, hemodynamic studies, stress tests, and radionuclear scans
- Advanced testing may include myocardial biopsy, cardiac catheterization, and genetic testing
Cardiomyopathy Pharmacologic Therapy
- Drug therapies include ACE inhibitors, ARBs, beta-blockers, diuretics, anticoagulants, digoxin, and aldosterone antagonists
- Tafamidis is a specific treatment for ATTR-CM
- Digoxin should be used with caution in HCM
- Electrolyte monitoring is important for all treatments
Cardiomyopathy Surgical Interventions
- Heart transplant is definitive for DCM, but not viable for RCM due to fibrosis
- Left ventricular assist device (LVAD) is used for circulatory support while awaiting transplant
- Surgical remodeling reduces left ventricular size for improved function
- ICD and pacemakers are used to manage life-threatening heart rhythm problems
Cardiomyopathy Lifespan Considerations
- Cardiomyopathy is a significant cause of cardiac death in children and infants
- DCM symptoms in children can range from asymptomatic to congestive heart failure, rapid progression is possible with viral myocarditis
- HCM diagnosis in infancy or adolescence, symptoms may emerge with growth spurts or physical activity
- RCM is rare in children and often caused by genetic factors, initial symptoms may be misdiagnosed as lung problems
Nursing Process for Cardiomyopathy Patients
-
Assessment and Education
- Primary goal is to ensure accurate symptom recognition and management
- Patient and family education should focus on understanding the condition, managing symptoms, and appropriate lifestyle changes
-
Nursing Assessment
- Thorough medical history including cardiovascular problems and familial history
- Assess symptoms, medications, diet, and activity level
- Physical examination including vital signs, general appearance, skin color, neck/extremities for signs of heart failure, and auscultation for heart sounds
-
Nursing Diagnoses
- Key nursing diagnoses include decreased cardiac output, fatigue, fluid volume excess, activity intolerance, lack of knowledge about the disease, and grieving
Cardiomyopathy Nursing Planning and Implementation
-
Planning
- Goals include maintaining blood pressure within target limits, adjusting lifestyle to reduce activity demands, and modifying diet to manage the condition
-
Implementation
- Prioritize monitoring of cardiac output and fluid volume
- Interventions include rest periods, elevation of head of bed, avoiding Valsalva maneuver, administering medications, oxygen therapy if needed, frequent vital signs monitoring, and monitoring laboratory values
-
Hypertrophic Cardiomyopathy (HCM) Care
- Management similar to myocardial ischemia, but avoid nitrates and vasodilators
- Post-surgery management requires adherence to open-heart surgery protocols
- Genetic counseling is recommended to assess familial risk
