Sleep Apnea and Sudden Cardiac Death: Mayo Clinic Finds Strong Link

This is a pretty shocking piece of research

scientists at the Mayo Clinic have concluded that obstructive sleep apnea is one of two highest risk factors for sudden cardiac death (SCD) – the other risk factor being age (being 60 years of age or older).

According to the researchers, OSA is implicated in sudden cardiac death because “low oxygen alters the blood vessels in a way that promotes heart disease”.

The study was carried out on nearly 11,000 people over a period of 15 years.

I’ve been trying to find a link to the complete study, but haven’t managed to find anything. You can take a look at the press release for the study here:

And here’s a quick YouTube video where Dr. Virend Somers discusses the link between OSA and heart attacks:
