Default Q.why EF can be noramal or inc in RCM?

Q. In restrictive cardiomyopathy (RCM), heart neither contracts nor relaxes normally.So, I was thinking ejection fraction should obviously decrease. But, when I was reading MTB , itís mentioned that EF may be normal or elevated in RCM.How is this possible, can anyone explain this. Thanks.

Because it mainly affects diastole. Contraction is minimally affected.
