Recorded at the 2014 British Cardiovascular Society meeting in Manchester, Heart associate editor Dr James Rudd talks to Dr Rob Casserley, summiteer of Everest, and his wife and cardiologist Marie-Kristelle Ross.

Rob initially worked as surgeon and is now a GP with a specialist interest in altitude and expedition medicine. He has climbed Everest eight times, including double summits in spring 2007 and spring 2010, and is the first-ever Western climber to have achieved this feat. He was been featured in "Everest ER", a BBC1 documentary series about medicine and climbing on Everest. He assisted Sir Ranulph Fiennes as doctor, guide and cameraman in a 2008 climb of Everest.

In this episode of the Heart podcast, they discuss high altitude, endurance sports and their effects on the heart and lungs in both health and disease.
