During a routing physical, I had an abnormal EKG & was referred to a cardiologist. Cardiologist repeated EKG, which again was abnormal. He did an ultrasound (with contrast), then stress test, then another ultrasound. Went back yesterday to cardiologist, who at first, didn't seem overly concerned about the ultrasound & stress test. Said heart wasn't 'relaxing' properly after each beat and MAY be a little hardening of arteries (which he did say was a bit abnormal for a 55 y/o, but again, he didn't seem too concerned about either issue). BUT.... when he again looked at the EKG's, whatever he saw didn't jive with the stress test & ultrasound. He now wants to do an angiogram and says he really has no idea of what's causing the EKG abnormalities. I'm 55 y/o, only slightly overweight, not a smoker or drinker, have VERY good blood pressure, pulse, oxygen saturation and cholesterol numbers. I did just recently have a nodule found on my thyroid (which had grown in size over the last couple of years, but is still considered small), which my regular doctor wants me to have checked out. Also, recently I learned that I was extremely low on vitamin D, for which I'm taking supplements. I had another EKG done about 3 years ago when I applied for life insurance and as far as I know, it was normal. Any thoughts on what this might be? Do you think the doctor is being prudent in wanting the angiogram (I have very good private isurance coverage). Thank you for any input, Gail
