E. all of the above
Idiopathic cardiomyopathy is diagnosed when no identifiable cause for the heart failure is found. Therefore, it excludes patients with:
- A: A history of valve disease
- B: A shunt inside or outside the heart
- C: Significant coronary atherosclerosis at autopsy
- D: Systemic hypertension, past or present
These conditions are considered potential underlying causes of cardiomyopathy, and their presence would lead to a diagnosis of secondary cardiomyopathy rather than idiopathic.
