What is considered a normal/healthy fluctuation in blood pressure? just diag.w/CAD-coronary atherosclerosis?

i am in my late 20's, diagnosed with mitral valve regurg at age 12 and last week was diagnosed with chronic ischemic heart disease-coronary atherosclerosis ( CAD) and also unspecified essential hypertension...my blood pressure has been perfect my entire life until very recently and i've just in the past 6 months had the symptoms that made me go to my cardiologist last week that led to my CAD diagnosis.
my resting heart rate now is averaging about 115 and i could only last 5 minutes on the exercise nuclear stress test before i reached my max. heart rate...my bp today has gone from its lowest of 114/80 pulse 116 to the highest of 149/101 pulse 84...why would my pulse go down so much when my bp increased and vice versa? at one point today i was having intense chest pains and shortness of breath and my bp was 149/97 pulse 105...any knowledge on this would be appreciated! i go to my cardiodoc tuesday to discuss angiocardiography so if anyone knows about those, please share too! thanks!

Its a negative feedback loop. As pulse decreases, then the body will react by increasing blood pressure through contraction of blood vessels, and vica versa. If pulse increases, then the body can reduce peripheral resistance to lower blood pressure. It sounds like your body is over compensating on each of these methods. Angiocardiography is a gold standard test for looking at heart vessels. Whilst lying down under a special x-ray machine, a tube is fed all the way to your hearts arteries from an artery in your leg. Once there, a special dye is injected (which you may feel as your face flushing). Then a picture is taken of the heart and where the dye has gone. This allows the Dr to see where there may be any obstructions in the artery.
