My blood pressure never increases with exercise and remains same to resting i.e, 125/80 level although heart rate increases to 166 bpm.I have questions below 1- is it true that sbp should increase with exercise to atleast 140 mmhg? 2- no change in bp signifies coronary artery disease or heart failure? I had positive tmt test but ct angiography came normal later.Had echo too, it was normal other than diastolic relaxation abnormality.
