Your best option would be to measure your blood pressure when on cycle.
If it is high, stay away from eca, or if you are persistent, start with a very low dose of eca, measure bp again, and work from there.
If your bp is whithin normal ranges, eca won't kill you, if you are healthy.
My blood pressure is never high for more than a week on eca, after a week it is normal again, but I am still getting stimulated.
P.S. usually I have low-ish blood pressure and heart rate, thus stimulants push it up closer to normal ranges, keep this in mind.
