One of the biggest risks for people with heart disease who are flying is developing venous thrombosis. These risks are higher if you have CAD or an implanted heart device, such as an artificial heart valve or a coronary stent. 3 And if you have an arrhythmia, a blood clot in your heart can lead to a stroke.

Being less active can lead to slow blood flow in your veins which increases your risk of developing a blood clot, known as deep vein thrombosis (DVT). DVTs most commonly form in the legs.

Airplane Travel and Blood Oxygen Saturation Local hypoxia causes vasodilation (decrease in blood pressure) and increased capillary permeability, as well as increased ventilatory effort and heart rate. One study found a passenger had a blood oxygen saturation of 94% at ground level and 85% at altitude.
