How can we cure the patient suffering from global hypokinesis, severe lv dysfuntion?

Severe heart failure: There is no cure for severe heart failure except a transplant. There are temporizing medications that can alleviate the some of the work the heart has to do, but it is not going to make the heart regain function.

No cure: Treatment will depend on cause. A search for reversible causes should be undertaken. The pt should be assessed for hibernating myocardium, hemochromatosis, severe hypertension, and toxins. A betablocker like carvedilol and an ACE-inhibitor should be administered. Digoxin may also be beneficial. If LBBB is present, resynchronization should be done. Advanced directives should be considered.
