Given my recent discussions with sports cardiologists and research, if it were me, I wouldn't worry about it. Angiogram revealed nothing actionable. I assume you will continue to be monitored.
My CAC was 1600+ last November. Angiogram revealed moderate blockage in the right coronary artery. Got a stent. I am cycling 40+ miles a week at 17+ mph on terrain with some hills. I try not to attack the hills the way I want to, but I basically do anyway. Oh well.
