Hello im a 23 year old male in reasonably good shape, physically im 6ft4 and about 195lbs, I have a hard physical job and i also cycle about 3 times a week. Anyway i recently purchased a home blood pressure monitor and my blood pressure seems to average about 110/60 at rest which is considered normal. My concern is my blood pressure readings after jogging for about 5 minutes, when i measure it immediately after exercise it can go up to 160/85 (this is taken when standing with arm hanging down). When i take it right after exercise sitting down resting my arm on the table bent at about a 90 degree angle it consistently averages about 160/60. From what i have read the systolic response is perfectly normal but the diastolic reading should stay about the same but mine increases significantly after exercise. On many websites it states that a significant exercise induced diastolic increase is indicative of coronary artery disease, i know im really young but i have a shocking family history of early heart attacks and heart disease on my fathers side. my grandfather died in his early 30s and two uncles died around 40, all had extensive arterial blockages. This has me real worried that i may have clogged arteries. When i visited my doctor recently i had an ecg which was normal and also many blood tests. My total cholesterol was about 150 (the test didnt provide a breakdown of LDL/HDL though) my triglycerides were low, my fasting blood sugar was 77mg/dl, CRP and ESR were both in the normal range, full blood count was normal so were serum chemistry tests. Prior to my blood tests he said he would book me in for a stress test but after all the blood tests he said further testing would be a waste of time. I explained my concern about the post exercise rise in diastolic blood pressure but he shrugged it off. This has me worried sick that im a heart attack waiting to happen despite my apparently good health. Anyway im wondering what the correct technique for measuring blood pressure right after exercise is, should the diastolic change that much based on body and arm position. To be sure the measurements were right i repeated the process multiple times and when measuring standing up with arm hanging down it was consistently around 160/85, and measuring seated it averaged about 160/60. an answer to this would be much appreciated as it has me real stressed out.
