Well, now I worry about my heart. I had a high calcium score, about 350, back in '17. Since October '22 I've had 2 syncopes at about 120 HR in spite of 2 cardiologists telling my there was nothing wrong with me that they could see from their tests. 2 stents later, no better, then a long-lasting nitrate med, no better, need a third opinion, this time from a sports cardiologist. Terrified my wife when I passed out on the rollers. No outside riding for me for a while.
