That score may be high for a 37 year old,but understand that not all is known about calcium scores. I am 75 and my score is 2500 and I have no symptoms. Had nuclear stress test and had Mets score of 13 which is equivalent performance of a 24 year old. Further test showed my three arteries to the heart were 90%,88% cand 88% open with good blood flow. Talk to your Dr. I would try to eat a dash diet,and if he says ok,hit the gym and exercise using aerobics and weights. I go 7 days a week for 80 minutes/ visit. Try not to worry and good luck.
