So calcified plaque while not great will almost never cause a heart attack or stroke. It's the soft plaque that will. Detecting soft plaque is not easy. Except in cartoid artery. Then a CIMT test can pick it up.
New scientific research is saying you cannot go by LDL number. The numbers that are more important are VLDL or small LDL or triglycerides/HDL.
Large LDL cannot pass through the inner artery wall. Only small LDL.
And I keep on reading on the topic.
And watch out of a hospital or imaging center that offers a CAC for $50. It's a loss leader. They hope you will have a high score so they can sell you more tests or procedures.
Not sure if you are following my posts. The gold standard for finding both hard and soft plaque is a Cardiac Angiogram. I was lucky and thankful to have a cardiologist be able to get it approved for me. I know all about this from the people on the male side of the family. I am the ONLY one so far who has not needed a quad heart bypass. I know all the procedures and why when I was having issues. mostly PVC related they managed because of my family history to get it done for me. I made it well known I wanted one.
SO they performed an invasive coronary angiography (ICA), It involves snaking a slender tube (catheter) through a leg or arm artery up to the heart and injecting a special dye visible on an x-ray. It shows both hard and soft. Actually it's the method used when a blockage is found during the procedure to place a stent and open the vein or artery.
I never had a CAC.
AS far as LDL ... getting it as low as possible (mine was always low) to help as much as possible for the uncontrollable Hi Lipo A (the other bad Cholestrol. All my lipids are stellar, always have been. Results Posted in here many times, however I have plaque "all over the place" according to the cardiologist who did my invasive angiogram. With that said, nothing to be done because the levels are at 20%. As an example, a stress test because of chest pain results will only show that if you have blockages of roughly 70% or more.
SO by keeping my lipids textbook perfect my whole life kept me out of the diabetes and heart by passes of family members. One of them used to make fun of the way I eat. However I have that "plaque all over the place" (exact words he told my wife)
I can only assume because of the bad Lipo A numbers I have. Soon there will be a drug for it, right now, nothing can be done except keep the numbers low.
I enjoy our conversations I can see you are informed on a lot of this stuff too.
I was going to look for my "films" but found this YouTube much easier. I'll never forget it, it was so cool, I was semi awake, they actually talk to you while they do it. I remember seeing large panel of displays in the room and I remember this image exactly when they were injecting the dye. It was creepy in the sense I was "not all there"
AN 8 second video of what happens once they thread the catheter up to your heart and inject the die. They did mine starting my groin area.
This is fascinating video of the above and during that procedure they find a blockage and open it up. I didnt need one but I encourage anyone if your doctor feels you should, do it. It's actually amazing, you wont feel a thing but you will sort of know what is going on.
If there is an issue, dont ignore it, the sooner they open up any blockages you will stop killing heart muscle.
