Not in detail familiar with his medical history, except for the pacemaker, here it is: (from BBC link)
DICK CHENEY'S HEALTH
Four heart attacks between 1978 and 2000
Quadruple bypass surgery in 1988
Fitted for pacemaker to regulate heartbeat in 2001
Operation to remove blood clots in 2005
He had FOUR clots in the heart in TWELVE years...!!!
His doctor does a good job keeping dead from knockin' his door.
Sure, this guy is at risk, but not anymore than should be suspected from air-travel.
Blood clots - or deep vein thrombosis (DVT) - can be associated with long-distance flying because it leads to inactivity and dehydration.
Clots themselves are not life-threatening but can be dangerous if they become wedged in the lungs or other organs, which can in severe cases be
fatal.
A survey done a few years back, showed even young people in their twenties would suffer minor clots in limps following air-travels, without necessary
feeling any discomfort they would notice.
So this is nothing... .. He didn't suffer a massive clot causing stroke of the leg.
Like I did ... could have screamed.
I ponder, why this news? ..they want us to worry ..about Cheney...??
