Sleep Apnea and Cardiac Risk

Here is an interesting article published in MedPageToday on the connection between OSA and cardiac injury markers in the blood.

The article links to the original study for those who have access to it. I don't as yet.

I can confirm this article by saying that I had OSA with AHI = 41 and had a heart attack with a troponin of 70. Pretty easy myocardial infarction. Also got a Tularemia infection in the body the same time.

The question for me was whether the levels of the marker dropped if the subject used CPAP?

I do not know, but I'll try to get a test. I suspect that my son who is 28 has sleep apnea. I'll ask him to have a blood test for Troponin. Then you can compare it later when he has been using cpap for a while.

That's an excellent article for sure!

Thanks for posting that.

I found another study done in Germany in 2011 that seems to compliment. It supports that it is never too late to begin xPAP treatment.

My problem with a lot of these studies from a purely scientific viewpoint is that obesity is associated with apnea and with metabolic sysndrome. It seems clear that the metabolic syndrome contributes to coronary artery disease.
It is not as clear what role apnea has.

can anyone point to a study that compares two groups with similar BMI's, one with apnea and one without?
