Acquired Cardiac Disease Rheumatic Fever Arterial Ischemic Stroke Arrhythmia
Pathophysiology of Rheumatic Fever • Also known as Kawasaki disease (KD) • Leading cause of acquired heart disease in children • An acute, febrile, multisystem disease is usually manifested by a self-limited generalized vasculitis of unknown etiology. (Ferri: Ferri's Clinical Advisor 2011)
Risk Factors for Cardiac Disease • Tobacco use • High blood cholesterol • Obesity • Poor physical activity • Diabetes
Demographics of Patient with Rheumatic Fever • Children <5 years old; peak age 18-24 months • Asian descent have highest incidence, followed by African Americans, Puerto Ricans, Mexican Americans and American Indians • Evidence of coronary artery disease
Signs and Symptoms of Rheumatic Fever • Fever (greater than 102.2 F) for more than 5 days and 4 out of the 5 below features: • bilateral, painless bulbar conjuctival injection without exudate • oral mucosal changes: erythema and fissured lips, strawberry tongue • polymorphous exanthema (in truncal region) • extremity changes: acute erythema and edema of hands and feet; membranous desquamation of fingertips • cervical lymphadenopathy <1.5 cm in diameter; unilaterally and anterior
Additional S&S of Rheumatic Fever • Cervical lymphadenopathy • Exanthema and extremity changes • Aneurysms of peripheral arteries (axilla) • Beaus’s lines (transverse grooves of the nails) • Diarrhea • Dyspnea • Arthralgia • Myalgia
Treatment for Rheumatic Fever • Reduce inflammation in systemic and coronary arteries to prevent arterial thrombosis (aspirin) • Prevent myocardial ischemia or infarction • Oxygen therapy • Salt restriction in pts with congestive heart failure • Emollient creams for peeling skin • Angioplasty and coronary bypass graft surgery for chronic conditions
Arterial Ischemic Stroke (AIS)Risk factors • Antiphospholipid antibodies • Increased Lipoprotein • DNA factor V Leiden mutation • Factor II genotype • congenital heart malformation • sickle cell disease and hypoxemia • meningitis • Cardiac procedures such as surgery, biopsy, interventions • Immobilization • Anemia • lipid metabolism disorders • Prothrombotic abnormalities such as anticardiolipin antibody, lupus anticoagulant, deficiencies in protein C and S and antithrombin
Signs and Symptoms of AIS • Fever • Seizures/symptomatic epilepsy • Cognitive impairments • Hemiparesis • Large middle cerebral or cerebellar infarcts
Treatment for AIS • Anti-thromotic therapies • Low molecular weight heparins (first choice) indications include arterial dissectino, coagulation disorders, embolisms from heart, progressive neurologic deficits • Heparin therapy • Aspirin- to reduce reoccurrence • Warfarin- for congenital or acquired heart disease, sever hypercoagulable states, arterial dissection, recurrent AIS while on aspirin • Thrombolytic agents • Neuroprotective agents • Immunosuppressive therapy • Stabilizing systemic factors and managing the causes
Arrhythmia Pathophysiology • IVNC- Isolated Ventricular Non-Compaction • Tachycardia • Abnormal heart rhythms • Can quickly progress to cardiac arrest and brain death
Demographics of Patient with Arrhythmia • Children or adults • Appear healthy • 44.8% are men with an average age of 66.8 years
Signs and symptoms of Arrhythmia • Symptoms are not obvious until disease is advanced • Heart palpitations • Dysarthria • Hemiparesis • Recent onset of nausea, vomiting and malaise • Tachycardia • Reduced systolic function • Anger and hostility common in men
Treatment for Arrhythmias • Anticoagulants decreases risk for a recurrent stroke by 50%
