Does anyone know what's considered exercise-induced hypertension? My systolic meassure during a maximal bicycle stress peaked at 220. The doctor didn't seemed concerned, however, I do have a slightly dilated left atrium and paroxysmal atrial fibrillation. I've been exercising quite a lot during my life time, and was wondering if this could have caused the left atrial dilation and AF?
Normal resting systolic BP, and everything else okay. Only 24 years old male.
Lots of peoples BP goes as high as 220 during a stress test. The Hypertension Specialist told me they done a survey on weightlifters, and their BP while they were lifting extremely heavy weights jumped as high as 240/130, all had normal BP when they were not lifting weights.
13 years ago, when I was 41 I had a stress test. I found the paper work and looked at the numbers. I was not taking any medication at that time. After 9 minutes at 3.5 mph, and when my heart rate was highest, @181 bpm, my BP was 168/80.
My resting BP was 140/90 and resting heart rate was 100 bpm. We are all very unique as you know. You could google if you need more info. If you do not have the time, I can help.
I would take the diagnosis of exercise induced hypertension seriously. I have been a heavy exerciser for 35 years and 5 years ago at age 54 found that I had a blockage in my LAD and first diagonal. Bypass surgery was the therapy. I have never smoked, had normal cholesterol, normal resting bp, and negative family history. A treadmill test a year before surgery revealed bp at max stress of 230/110. An echo also showed left ventricular hypertrophy, another symptom of high bp that I didn't have,except during exercise.
I found a case study in one of the medical journals of an 50 year old marathoner much like myself who was a physician himself. 64 slice CT scan reveal extensive atherschlerosis, although he was not symtomatic. His risk factors were similar to my own and also had exercise induced hypertension. The journal authors opined that the amount of time he spent above 200 mm systolic was in excess of 30 minutes per day and probably the cause of his CAD. They also found that vitamin E and C given before exercise reduced the inflamation due to the high bp rather quickly.
