after a heavy session aerobics and gym my blood pressure was 183/99 pulse 92. Can this damage my heart? I'm 85, one stent 2010, I can do 5kms bike and gym and be sick - nausea, anxiety belly ache, body malaise, pre syncope, drop- down fatigue in the same day and cannot identify the cause. (these events can be in reverse order). Medicines: Rhythmol 150, Coreg 6.5, aspirin, levothyroxine .75, Crestor 10 alternate days. But how about that 183/99? (in 15 mins it was down to 122/71 p77.
