Hi I am 63 tall and maybe 4 kg overweight I have run all my life 20 -40 km a week HR is around 58 have slightly high bp was 145/130 but controlled now and is normal. My CPK is a bit high around 340 i excercise in the gym at quite intensity at times hard to get my pulse rate over 38 on the bike. Is the high CPK a big area of concern my physician is following it up. Great service thanks very much
Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would like to explain that your increased CPK level seems to be related to excessive muscles strain, which causes muscle CPK isoform (MM) to be highly increased in blood circulation. Other alternatives may be possible, like inflammatory or autoimmune disease, some Chat Doctor. It is important to frequently check CPK level trends by repeated lab tests, to better differentiate between possible alternatives. So your attending doctors decision, seems to be rationale in the diagnostic work up process. Hope to have been helpful! Greetings!
