I think there was a compliment in there somewhere!
In a nutshell - CT angiogram to try and see what was what before getting into statins for 6.4 total cholesterol (4.0 LDL)
CT showed Coronary Calcium Score almost off the clock - 1453 which put me in 99th percentile
Next step Nuclear Stress Test. 14.4 mins on treadmill reaching workload of 17.2 METS. Pulse from 68bpm at rest to 181 bpm at peak exercise. That was 106% of maximum for age etc. Blood from 124/78mmHg to 226/98mmHg
Outcome was LVEF at rest of 61% but only 38% post-stress.
No shortage of breath, chest pain, tingling or other symptoms. Was running half marathons until CT angiogram resul a few weeks ago.
Seeing cardiologist next for expected formal angiogram.
What the f*** is going on here. Heeeeeelp!

Systole volume prior to contractions at rest would have the highest numeric value (peak), and diastole prior to filling and after systole would be the lowest value. Subtract diastole from peak systole and devide by peak systole would provide the fraction of volume pumped with each heart beat.
A faster heartbeat does not provide enough time to fill as at rest, and the timing of contractions are less. The percent of blood pumped with each heartbeat is less reducing stroke volume (lower EF). The heart rate has increased to provide the necessary blood/oxygen to meet the system's demand for the diminished stroke volume.
The CT scan indicates there is substanital soft plaque buildup within the linings of the vessels. A couple of years ago, my total CT score was/is over 1000 and that is supposed to indicate a high probability for a heart event within a year....waiting for the other shoe to drop!...no problems, feel fine.
