There are two causes for diastolic blood pressure and that is mainly determined mainly by cardiac output (amount of blood pumped into circulation at 1 minute intervals and peripheral vascular resistance.
For some insight, with exercise the heart pumps faster increasing cardiac output (CO), and there is a dilation of peripheral vascular vessels with the exercise as the vessels present less resistance the diastolic blood pressure should be reduced. Is your diastolic BP of 97 at rest?
Has there been a test to determine tha amount of oxygen in your blood? Has there been pulmonary function tests? Blood tests—to check for anemia or low blood count. Thyroid gland production normal?
Thanks for your questions, and if you have any followup questions or comments you are welcome to respond. Take care. Ken
Thanks. My diastolic was 97 at rest. Prior to this new medication, it only was high with exercise. I seem to be having a backwards response to this medication. I am actually waiting for PFT results right now. Oxygen saturations are normal, bloodwork is normal other than I had liver enzymes(ggt, ast, alt, alkphos) done last week and they were mildly elevated which is new for me. I wondered if it might be from the medication.
