What is left ventricular hypokenisis?

[Grammycher]

My son, age 30, just had a stress test and the results showed that he has left ventricular hypokenisis - 44% blood flow?  He is going to have another echocardiogram and be referred to a cardiologist.  The family history is that his paternal grandparents, along with his paternal uncles, all died of some sort of heart disease before the age of 65. My son is otherwise healthy, doesn't smoke, is physically fit, not overweight.
I'm concerned about what this diagnosis means for him.

It appears your son may have some heart wall movement disorder (hypokinesis).  The impairment will/can cause the ability of the heart to be pumping with normal contractility.  The 44% appears to be the amount of blood pumped with each heartbeat. The ejection fraction (EF) is normally 50 to 70%.  

Your should be in consultation with the doctor to determine the underlying cause for the hypokinesis.  Usually, it is due to insufficient blood flow to the area of the imparment.

Thanks for sharing, and if you have any further questions or comments you are welcome to respond.
