Researchers say one of the biggest risks facing people with heart disease when flying is venous thrombosis, or the formation of a blood clot in the veins of the leg, pelvis, or arms. Sitting long hours, dehydration, and the lower oxygen levels in a plane cabin can all predispose a person to blood clots.

Can flying cause a stroke?

Air travel increases the risk of developing blood clots in the veins of the legs, which can then enter the bloodstream and block an artery in the lungs, a condition called pulmonary embolism. In some cases, the opening can allow the blood clot to enter the arteries of the brain, causing a stroke.
