I came across an article in our local paper yesterday.
(I'll paraphrase because there is no online link)
****************************************************
Melbourne researchers at the Alfred Hospital have found that most heart attacks are suffered in the 6.00 am - 9.00 am hours. The cause has been postulated as low levels of oxygen (hypoxia) cause by sleep apnea/snoring. The hypoxia leads to a pressure drop in the chest cavity causing the heart to 'twist' or distort straining the coronary arteries that connect to the heart. The twisting dislodges collected plaque from the inside walls of the
arteries. The process was likened to twisting an ice cube tray to pop out the cubes.
Further, the stress of the condition triggers an increase in adrenaline, which combined with the hypoxia causes the blood platelets to become more 'sticky'. This can cause serious complications as sticky platelets are magnets for ruptured plaque which over a short time can lead to clotting and thence to a stroke or MI. More than 90% of heart attacks were due to plaque
ruptures and clots said Prof Matthew Naughton (any relative Simon ? ;-)

If guys are going hypxic on these things for whatever reason, this may be an explanation for why the coroners don't look any further if they find 'evidence' of MI.
