Your end-diastolic volume (EDV, heart filled with blood) is quite high, but the end-systolic volume (ESV, heart emptied) too.
So with every stroke, your heart pumps out 68ml of the 163ml it contains, which is 42%. This is below normal (normal range is 55-70%).
This lower than normal ejection fraction (EF) of 42% is caused by the less tan normal action of parts of your heart muscle (hypokinetic .....).
There is moderate regurgitation (leakage) of the two valves (mitral valve and tricuspid valve) that separate the atria from the ventricles.
This needs not be a big problem, but requires monitoring (1x or 2x/yr).
What kind of treatment have you got for your chest discomfort?
