Study Notes
Rheumatic Heart Disease
- Rheumatic heart disease (RHD) is a condition that affects the heart valves due to an untreated strep throat infection.
- RHD typically affects children between the ages of 5 and 15.
- It is more common in crowded living conditions and lower socioeconomic groups.
- Factors contributing to RHD include poor oral hygiene and untreated throat infections.
- RHD is diagnosed based on the Jones criteria, which includes major and minor criteria.
RHD Major Criteria:
- Carditis (inflammation of the heart)
- Arthritis (inflammation of the joints)
- Chorea (jerky, involuntary movements)
- Erythema marginatum (a rash)
- Subcutaneous nodules
RHD Minor Criteria:
- Fever (over 38.5°C)
- Elevated ESR (erythrocyte sedimentation rate)
- Elevated CRP (C-reactive protein)
- Prolonged PR interval on ECG (electrocardiogram)
RHD Treatment:
- Antibiotics such as penicillin are used to treat the underlying infection.
- Anti-inflammatory drugs like aspirin may be prescribed.
Bacterial Endocarditis
- Bacterial endocarditis (BE) is an infection of the inner lining of the heart, typically affecting the heart valves.
- BE is primarily caused by bacteria, commonly streptococci.
- BE can occur after valve replacement, known as prosthetic valvular endocarditis.
- BE can also occur as a result of other infections, such as those of the mouth or skin.
BE Symptoms:
- Fever (often mild)
- Night sweats
- Fatigue
- Weight loss
- Chills
- Joint pain
BE Diagnosis:
- Blood cultures are used to identify the bacteria causing the infection.
- Echocardiogram is used to assess the damage to the heart valves.
BE Management:
- Antibiotics are used to treat the infection.
- Other treatments may include:
- Cardiac stabilization
- Oxygenation
- Hemodialysis (for renal failure)
- Salt restriction (for congestive heart failure)
- Activity limitation (for heart failure)
Myocarditis
- Myocarditis is inflammation of the heart muscle caused by various factors, including infections and drugs.
Myocarditis Types:
- Infectious myocarditis is caused by viruses (HIV, Coxsackie), bacteria (streptococci, staphylococci), fungi, and parasites.
-
Non-infectious myocarditis is caused by:
- Cardiotoxins (ethanol, heavy metals, radiation therapy)
- Inflammatory diseases (Kawasaki disease, Takayasu’s disease, sarcoidosis)
- Certain drugs (doxorubicin, daunorubicin, cyclophosphamide)
- Giant cell myocarditis is a rare form of myocarditis with an unclear etiology but possibly linked to an autoimmune mechanism.
Myocarditis Symptoms:
- Fatigue
- Dyspnea (shortness of breath)
- Edema (swelling)
- Fever
- Muscle aches (myalgias)
- Crackles in lungs
- Third (S3) or fourth (S4) heart sound
Cardiac Tamponade
- Cardiac tamponade occurs when fluid builds up in the space between the heart and the sac surrounding it (pericardium).
- The fluid buildup compresses the heart, making it difficult to pump blood.
Cardiac Tamponade Symptoms:
- Chest pain
- Shortness of breath
- Dizziness
- Fainting
- Neck vein distention
Cardiac Tamponade Diagnosis:
- Echocardiogram
- Chest X-ray
- Electrocardiogram
- Computerized tomography (CT) scan
- Cardiac enzymes
Cardiac Tamponade Management:
- Oxygen
- IV fluids
- Medications (inotropics)
- Pericardiocentesis (removal of fluid from the pericardium)
- Pericardiectomy (removal of part of the pericardium)
- Thoracotomy (opening of the chest for drainage)
Valvular Disorders
- Valvular disorders involve damage or defects in the heart valves (mitral, aortic, tricuspid, or pulmonary valves).
- Valvular disorders can cause narrowing (stenosis) or leaking (regurgitation) of the valve.
Valvular Disorders Diagnosis:
- Echocardiogram
- Exercise testing
- Cardiac magnetic resonance imaging
- Cardiac catheterization
Valvular Disorders Management:
- Medication (vasodilators, diuretics, nitrates, digoxin, calcium blockers)
- Low sodium diet
- Avoiding strenuous activity
- Surgery (including percutaneous balloon valvuloplasty, valve replacement, or repair)
Nursing Care for Cardiac Conditions:
- Monitor vital signs (heart rate, blood pressure, respiratory rate, oxygen saturation)
- Auscultate heart sounds for murmurs
- Monitor for signs of pulmonary congestion (shortness of breath, crackles, pink frothy sputum)
- Monitor intake and output
- Administer prescribed medications
- Prepare patients for surgery
- Teach patients about their condition and treatment
- Provide emotional support
- Encourage healthy lifestyle changes (smoking cessation, diet modification, exercise)
