The risk of deep vein thrombosis (DVT) remains the same when people travel via air or take a train, experts have revealed.

"For those with cardiovascular disease who are not critically ill, but who wish to fly on commercial aircraft, the aircraft environment does not pose a significant risk to their health," The Scotsman quoted Dr David Smith, a cardiologist from the Royal Devon and Exeter NHS Foundation Trust, as saying. "It is only when their under-lying condition is associated with a significant risk of acute deterioration that reasonable restrictions should apply."
The guidance from the BCS follows a directive from the House of Lords calling for comprehensive information for passengers, doctors and airline carriers on the risk of heart issues caused by flying.
