Hypertrophic Heart muscle enlarge without any cause; ventricle to become thick. Thickening may block blood flow out of the ventricle (workload) Restrictive (rare) Deposition of substance, cause ventricle become stiff/rigid Cant relax normally and fill with blood Later ventricle do not pump as well and heart muscle weakens.
