Hello and thank you for using HCM.I carefully read your question and I understand your concern.You shoud not worry about this . I will try to explain you something.
When you do the
angiography a substance called contrast is injected into you blood, into your coronary
artery to make them visible and look for stenosis.
This contrast is than eliminated through the
kidney and goes outside the organisms whith urinary output.
During the first 48 hours after the angiography, as the contrast in still in our body it might couse
hypotension,
nausea,
vomiting.This is quite normal after the procedure.
But usauly after 48 h it is eliminated from the organism.
So, if the angiography was normal, if the renal function after was normal and if 48 h has passed every think should come back to normal.
The blood pressure values of 115/75 are quite normal, you should not worry about this.This values are our goal.
So in my opinion your symtoms are not related whith angiography, it might be just a
flu that soon will pass.Or it might just be a little streess as you experience even fast heart beats.
If the symptoms persist if I was your treating doctor I will recommend a full blood analyze to find a reason why you feel tired or this nousea.
Hope I was helpfull.
Best regards.
