Restictive pattern of LV Diastolic Filling

I am 23. no real big symptoms other than the occasional shortness of breath and a typical chest pain. I have never had a heart problem other than a murmur when I was a kid, but the cardio wanted me to have some tests done. he said he didnt suspect any significant heart disease so i had a echo and a stress test. I did the stress test he said that my resting BP was OK 120/62. but when i excercised it went up maybe an indicator I will have high BP in the future. now the results of my echo is what is really scary because I am reading online about it. the summary is as follows:
Left ventricular ejection fraction is 50%
Left ventricular cavity is mildly increased
Mild concentric left ventricular hypertrophy
RESTRICTIVE PATTERN OF LV DIASTOLIC FILLING
that is the one that is really scaring me! everything I read is that is in advanced severe cases. why would I have this and not have any symptoms? is it reversable and what is the prognosis? I will also include the parameters
MV Peak E- 1.09 m/s Lat e', MV ann- .19 m/s
MV Peak A- 0.35 m/s Lat E/e' Ratio- 6
E/A Ratio 3.11 Sep e' MV ann-0.14 m/s
Sep E/e' ratio 8
Avg e' 0.17 m/s
Avg E/e' Ratio 7
Te'-TE 14.50
IVRT/TE 3.72
LV IVRT 54 msec
MV DT- 363 msec
Sorry so long but any information would be greatly appreciate. What heart diseases do you see these in? what heart disease would I be suspected of having and the prognosis. thank you

Q: Left ventricular ejection fraction is 50%

>>Ejection fraction is the percent of blood pumped out of the left ventricle cavity with each heartbeat...normal is 50 to 70%.

Q: Mild concentric left ventricular hypertrophy

>>Concentric LVH is an increase in LV wall thickness.

Q: RESTRICTIVE PATTERN OF LV DIASTOLIC FILLING

>>Diastolic filling of the left ventricle is normally in 2 phases and referred to as the E/A ratio.  The E is the early filling phase and the A is the following phase with the upper chamber contraction and pump blood into the left ventricle.  When the heart wall is thickened the left ventricle does not fill very well due to the rigidity of the heart wall so the "A" phase may be compromised (restricted pattern of filling).  Of additional medical significance is the atrium (upper chamber) pumps against a higher resistence and may enlarge.

Hope this provides a perspective, and if you have any further questions or comments you are welcome to respond.  Take care,
