CR - Cardiomyopathy
Dilated
progressive, gradual, often idiopathic

-
-
-
-
Hypertrophic
obstructed dias filling (reduced end diastolic vol, hence reduced CO)
powerful hyperkinetic contractions, but ventricle walls stiff
-
myocardial ischaemia common (not due to CAD, hypertrophied muscle requires more O2)
-
-
-
Restrictive
-
-
decreased ventricular compliance (distensibility, i.e. relaxation during dias)
-
-
aetiology
non-infiltrative (idiopathic or familial, but genetic factors less well -defined)
-
storage - haemochromatosis (Fe overload, deposited in heart, blue on Perl's Prussian stain)
