I just got my results back from a echocardiogram. Can anyone explain what they mean?

There is Grade I left ventricular diastolic dysfunction.

I suffer from, dizziness/lightheaded, migraines, chest pains off and on, fast heart rate, I'm tired all the time, coughing, head rushes when I stand, anxiety, shortness of breath. This has been going on a little over a year and a half.
