I also have a high score. I'm an active 79 yr old male with a calcium score of over 6000. I feel an unusual shortness of breath (according to me) during exertion so I had the CAT scan done. Dr. also preformed a catherization which showed a 60% stenosis in the distal third portion of LAD. He did not put a stent in as he felt I would not feel any better plus stent size would have been 2mm which tend to collapse. He now has me trying ranolizine to see if it alleviates my sob. Also said that there is nothing that can be done to lower the calcium.
