cardiomyopathy in acromegaly ???

[pre med 2014]

UW says you get concentric cardiomyopathy (so sarcomeres in parallel make the LV wall thick and volume capacity low) but then it says it also causes LV dilation and hypokinesia (which is the opposite of concentric, eccentric would be sarcomeres in series)

A hypertrophic heart would have increased contractility and decreased compliance (diastolic dysfunction) all of this I understand but the part about LV hypokinesia is driving me crazy someone please explain

Both hypertrophic and dilated cardiomyopathies can happen,GH
have a trophic and positive inotropic effect on the myocardium but also causes secondary HTN, DM and CAD which all can induce significant impairment of the Contractility of the heart and eventual dilatation.
