Hypokinesis is a medical term to indicate there is a heart wall movement impairment and that will have an impact on the heart's ability to forcefully contract as heart cells are damaged.
Ischemia indicates there is some blockage of the blood flow to the subject location and that can be the underlying cause for the hypokinesis. The treatment would be to increase the blood flow to the location by dilating vessel....therapy can be medications, stent implant or bypass.
Generally if medication dilates vessel sufficiently that could be the option, if medciation doesn't relieve symtoms such as chest pain, then a stent implant would be appropriate, and if the stent implant is not appropriate due to location, size, etcl. then a bypass.
Hope this provides an insight and a perspective that can help you discuss the options with your doctor. Thanks for the quesiton, and if you have any further questions you are invited to respond. Take care,
