ESC reaffirms advice on cardiovascular risks associated with long-haul flights

Following a review by The Lancet of the medical issues associated with commercial air travel, the European Society of Cardiology has reaffirmed its advice about the risks of venous thromboembolism (VTE), whose risk, according to The Lancet, is increased "up to four-fold" by long-haul flight. Dr Steen Kristensen, Vice-president of the ESC, says: "Long distance flying is associated with an increase in deep venous thrombosis, which in some cases may lead to clotting of the lungs. People who are immobile, pregnant, taking contraceptive pills or have had venous thrombosis in the past are particularly at risk. To minimise the risk it is important to drink plenty of non-alcoholic fluid and to walk (exercise) before and during the flight. The use of compression stockings is for some travelers an important way of preventing deep venous thrombosis." Studies cited by The Lancet suggest that the risk of VTE increases when flight duration exceeds four hours. This raised risk is related to immobility, dehydration, and reduced oxygen in the cabin, as well as to individual risk factors such as obesity, recent surgery and predispositions to thrombosis (thrombophilias). - EurekAlert

In-flight health issues 'on rise'

"Growing numbers of older passengers and ever longer flights mean the likelihood of health problems in the skies is increasing, US researchers suggest. From blood clots to flu pandemics, both travellers and authorities should be aware of the risks - and seek to minimise them - a Lancet review urges. An ageing population means passengers are boarding planes with existing health problems, researchers warn. Extended flight times could also increase the risk to health, they say. The review of the many studies into the health risks of flying found an overall association between air travel and venous thromboembolism (VTE), which occurs when a blood clot in a leg vein travels through the body to the lung" - BBC
