False regarding restrictive cardiomyopathy is-
Ref: Harrison's 19th E pg: 1566 Both atria are enlarged, sometimes massively. Modest left ventricular dilation can be present, usually with an enddiastolic dimension <6 cm. End-diastolic pressures are elevated in both ventricles, with preservation of cardiac output until late in the disease. Subtle exercise intolerance is usually the first symptom but is often not recognized until after clinical presentation with congestive symptoms. The restrictive diseases often present with relatively more rightsided symptoms, such as edema, abdominal discomfo, and ascites, although filling pressures are elevated in both ventricles.
Filling pressure is increased
Left ventricular hyperophy
Hea failure is not predominantly right sided
In early phase, systolic function is not impaired
