I am a very active ( 60 yrs) , run and play hockey. NO cardiac symptoms but High cholesterol and calcium score motivated me to get an CT angiography. I was wise to push for this test as it showed a 75% LAD blockage which required statins and a stent. That was six months ago in which time my cholesterol has dropped from to 240 to 150, and the LDL from 147 to 55, HDL steady at 65. Hope this helps.
