When there is hypokenisis it usally indicates there has been a myocardial infarction (heart attack) and some heart cells are dead (necrotic). The condition can be mild to severe.
Ot there can be a condition resulting from ischemia (lack of blood supply) and the deficit of blood to heart cells can put the cells into hybernation or stunned. Restoration of blood supply caused by occlusion, etc. can revitalize the cells and pumping fuctionality can return to normal.
Treatment would be to reduce the heart's workload with medication to relieve a weak heart from the stress and prevent or slow any progression if the underlying cause is partially due to high blood pressure. Also, there is medication to increase the heart's contractions and medication to reduce cholesterol.
To answer your question more directly, one would need to know the underlying cause. An EF of 41% is not dangerously low, and no perfusion abnornality (no occlusions of vessels noted). This seems to indicate you had an ischemic heart attack, and vessel (s) were stented or bypassed and no evidence of any lesions at the time of your test.
What do they do to treat this?
I had this test done in January and only found out about the results because I got a copy of my records yesterday. I am worried that it has gotten worse because they have not treated it.
Is there anything I can start doing myself until I can see the cardiologist.
Mild global hypokinesis is slight heart wall movement impairment globally rather than to a specific area of the heart. This condition would be the source of the less than normal ejection fraction (normal is 55-75%) and is an indication of the percent of blood pumped into circulation with each heartbeat.
