Segmented LV wall motion abnormalities (hypokinesis) are characteristics of myocardial infarction. The damaged myocyte heart cells inhibit the contractilty of the heart chamber thereby reducing EF (ejection fraction...amount of blood pumped into circulation with each heartbeat...normal is 55 to 75%).
FS is "fractional shortening": It differs from EF (calculations are associated with chamber volume/capacity before and after contractility) in that an enlarged LV functioning is associated with the calculation of the dimensions (before and after contractility) of heart chambers. Normal range: above 30% is considered normal, 26 to 30% represents a mild decrease in ejection fraction.
An angiogram is to determine if the underlying cause for less than normal EF and FS is associated with ischemia (blocked coronary vessels). It appears the valves can be ruled out as the underlying cause (an echo is the best test for valve integrity and functionality) as trivial and mild are considered insiginificant..
An angiogram is a test that injects a contrast dye into the blood stream and takes images of heart vessel blood flow. An interventional angiogram is with a cath, a CT scan 64 slice angiogram is almost as good as a cath and can be a test of choice.
There should be some concern as the condition if not treated can develop into heart failure, arrhythmia, etc.
