Background
- Idiopathic form accounts for 25% of CHF
- Viral/chronic myocarditis is most common identifiable causes
- Other causes
- Ischemic
- Familial dilated cardiomyopathy
- Other infectious - HIV, Lyme, Chagas
- Toxic (EtOH/beriberi, cocaine, meth, chemo, heavy metals)
- Hyperthyroidism
- Autoimmune, SLE
- Connective tissue disease
- Hypertensive dilated cardiomyopathy (as opposed to hypertensive hypertrophic cardiomyopathy)
- Infiltrative disease
- Sarcoidosis
- Peripartum cardiomyopathy
- Mitochondrial disease
- Tachycardia-mediated
- ESRD
Diagnosis
- CHF symptoms
- CXR
- Cardiomegaly, pulm venous htn
- ECG
- LV hypertrophy, poor R wave progression
- Ultrasound
- Bedside (for gross function)
- TTE/TEE for EF
Differential Diagnosis
Cardiomyopathy
- Dilated cardiomyopathy
- Hypertrophic cardiomyopathy
- Restrictive cardiomyopathy
- Peripartum cardiomyopathy
- Takotsubo cardiomyopathy
- Arrhythmogenic right ventricular dysplasia
Treatment
- Similar to CHF exacerbation
- Ensure exacerbation not due to ischemia
