Common readers of my column know I’ve been very bullish in regards to the Coronary Calcium Scan, also called a calcium rating take a look at or coronary calcium rating, as a take a look at for coronary heart illness threat. I take my lead from a heart specialist, Dr. Henry Sadlo, who has been championing this trigger for a number of years.
CCS has been instrumental in saving many lives and one more reader wrote in lately to inform me about their expertise with the take a look at.
“I used to be sitting at residence watching TV with my spouse once I felt a pointy ache in my chest. A short while later the ache additionally ran down my left arm at which level my spouse advised me I wanted to get to the hospital,” this reader wrote. “I did they usually ran checks on me a number of occasions by means of the night time, however couldn’t discover something flawed. Their conclusion was it should have been heartburn or gasoline.”
“The knowledge was plugged into my chart on-line and my private [doctor] of a few years noticed it and referred to as me, insisting that he see me instantly. After we met the subsequent day, he advised me he wasn’t satisfied there was nothing occurring and that he had already organized for me to take a CCS take a look at,” the reader continues. “I shrugged and agreed to maintain the appointment, and fortunately I did. My CCS rating was over 800, alarmingly excessive, and worse, there was a problem with the so-called ‘widow-maker‘ artery. An appointment was made for the subsequent day with a heart specialist. Two days later I had coronary heart surgical procedure with two stents.”

The reader continued: “Had I not had a private [doctor] who cared a lot about my wellbeing and who knew the advantages of the CCS, there’s a good probability I quickly would have had an enormous coronary heart assault and never be scripting this. I’m deeply indebted to my physician, and I thanks and Dr. Sadlo for beating the drum on this non-invasive process that saved my life.”
How a lot does a Coronary Calcium Scan value and is it lined by insurance coverage?
Let me clear up some confusion, and considerations, about why the CCS just isn’t lined by most medical health insurance.
It is typical for brand new checks to take fairly some time earlier than they’re adopted for insurance coverage cost. There are many causes for this, together with that new checks usually imply further expense, and it is a pure enterprise determination to withstand new bills so long as attainable till the proof is overwhelming that sure checks ought to be lined as a part of “primary” healthcare.
Out-of-pocket value for the CCS varies however is roughly $100. The letter above, plus many testimonies from Sadlo’s sufferers, make it fairly clear, for my part, that it is cash properly spent.
One other impediment is that the CCS measures calcified plaque within the coronary heart arteries. Plaque is first deposited within the arteries as a “mushy mass” of ldl cholesterol and different particles. Over time, calcium invades these mushy plaques, cementing them in place, thus the time period “hardening of the arteries.” The issue when contemplating outcomes from a CCS is you might have substantial clogging in your arteries that’s nonetheless within the mushy stage and wouldn’t be detected with a CCS.
In flip, this might present a false sense of coronary heart well being with a CCS rating of zero.

However even with this limitation, the CCS take a look at remains to be a particularly helpful device. What’s extra, nearly all checks have some limitations. For instance, the blood stress in my arm could also be far totally different from the blood stress in my ankle. In that case, it might point out extreme vascular issues. So, does this imply it is not worthwhile to measure the blood stress in my arm because it tells nothing about what’s going on in my ankle? Or, does it imply this limitation is famous and extra steps ought to be taken? The reply is apparent.
