Wondering about Heart Rate and Cardiac PET Stress Test results

I am a 64 year old, white, female, not really active, but don't just sit all day.  Have been feeling fatigued and short of breath for quite a while.  Pulmonary dr. did Pulmonary Function Test and Chest CT Scan, all good there.  I saw my cardiologist and he ordered a nuclear PET stress test. Results follow.  I have noticed on my PCP records that over the past 3 years or so my resting HR is in the 70's or 80's at their office.  Bad cardiac family history.  I also have mitral valve insufficiency; scheduled for echocardiogram on 02/26/2020.  Any reason to be concerned?    
Reason for Appointment
1. PET - SP
Vital Signs
Wt 150 lbs, Ht 61 in, BMI 28.34 Index, BP 106/66 mm Hg, HR 70 /min, Oxygen sat % 99 %.
Stress Test:
       Nurse: Bill Farmer, RN.
       Technologist: Robin Jones, CNMT.
       Ordering Physician:  Dr. Pasupuleti.
       Interpreting Physician: Dr. Pasupuleti.
       Study Quaility: Good .
       Procedure: Cardiac Positron Emission Tomography: The patient underwent a stress test utilizing 0.4mg of IV Lexiscan infusion over 10-15 seconds. The patient experienced stomach pressure during the procedure and received no medications. The patient had a myocardial perfusion imaging performed using same day imaging protocol, with the injection of 30.0 mCi of Rubidium-82 at 30 seconds into Lexiscan infusion, and the injection of 30.0 mCi of Rubidium-82 at rest. Imaging was performed by gated resting and gated stress technique ,.

Just if my heart is pumping OK.  I have tried reading about the EF and it sounds like numbers over 70 are concerning.  Not sure, just looking for some idea of what is considered bad as far as high EF.  I read 50 and lower is very concerning.  Thanks for any insight.
At first glance... you do have very mild ishemia but its reversable so my gut is that its arterial spasms.

The ef is too high imo... i would think hypertrophy of the ventricles but for some reason they said it looked fine?  So, its something id inquire about ... diastolic dysfunction.

The othet thing thats slightly odd is that your heart rate really did not elevate much.

Those are just my thoughts... I would talk to your provider and seek another opinion to feel more confident.
