Susie,
Yes, that's a number my doctor watches. I've gotten copies of all my echoes, one of which is from a different facility. Even trying to compare the results between them is confusing because they all use different abbreviations or don't always show all the same measurements.
My cardiologist told me recently my "heart size" was 5.7. When I got the echo and read the results it showed LVIDd as 6.3. When I brought up concerns about a brother's recent surgery and sister's impending surgery he told me I'm "no where near surgery".
You mention "Left Ventricle Systolic Dimension". I don't find that on my reports, but have LVIDs and mine shows 3.9.
