Went to see the documentary, “The Widowmaker” a couple of weeks ago. The screening was sponsored by the doc who has done my CIMT’s and has treated LC/HF for 15 years. It was also sponsored by a primary care doc who does EBT coronary calcium scans. I ordered his CD’s and on them he says to distribute them widely.
Here is a Google Drive link as the files are too big to upload to this site. In the root directory is a PDF of the doc’s brochure. There are two CD’s and I’ve put the mp3 tracks from each in their respective folders. https://drive.google.com/folderview?id=0B-8LUT_rIblDam5Fc09EWi1iaFU&usp=sharing
I think this paper is where he gets a lot of the ideas on progression less than 15%/year means stable plaque and low heart disease risk. http://atvb.ahajournals.org/content/24/7/1272.long
He references the MESA study. Here is a search on it:https://www.google.com/search?q=mesa+study+calcium+score&ie=utf-8&oe=utf-8
I've learned that the general scanners at the hospitals generate 3-12 mSv. His EBT scanner (which is not general purpose) generates 0.7 mSv with high accuracy (same range as mammogram exposure). Other exposures for comparison: http://www.radiologyinfo.org/en/safety/?pg=sfty_xray
- get baseline scan @ 40 if male, 50 if female, earlier if family history or other indications
- if zero, retest in 5 years unless family history or other indications
- if >0 when you retest depends upon score
- if >0 institute lifestyle & other treatment (possibly including low dose statins), depending upon level
- goal is <15% year increase as his interpretation is plaque is stabilized and unlikely to rupture.
I plan to do this. His cost is $195. For me, it looks like a way out of the LDL-P correlation loop - some people eating LCHF have high LDL-P no progression. The doc who does my CIMT's is in this category. His LDL-P is 1700 and his calcium score is 0. He has lots of patients likewise. However, it is hard to know whether one is in this category or not. Serial calcium scans looks like a hot option for me. Especially with an EBT scanner, since the radiation level is acceptable (0.7mSv).
