Restrictive Cardiomyopathy
Prognosis for Restrictive Cardiomyopathy
Prognosis is poor (see table) because the diagnosis is often made at a late stage. No treatment is available for most patients; symptomatic, supportive care can be provided. Standard therapies that are used in dilated cardiomyopathy (eg, angiotensin-converting enzyme [ACE] inhibitors,digoxin, beta-blockers) are poorly tolerated in restrictive cardiomyopathy. Patients with restrictive cardiomyopathy may also have autonomic dysfunction (especially in amyloid heart disease) or low systemic blood pressure. There is a high rate of conduction system disease, heart block, and sudden death.
