My name is Ron and I had three stents fitted a few days ago after a "cardiac episode" completely out of the blue so this is my first post. I have a long holiday booked to the States this summer which involves one location that has temperatures around 38C (the rest are around 28-30) and several locations in the 2000-2400 metre elevation range. I note the BHF advice to avoid extremes of temperature (what does that actually mean?) and elevations over 2000m which my consultant repeated. But how absolute is that advice (I didnt have the chance to question the consultant further)? Is it OK to be at a higher elevation (with lower temperatures) for a few days provided you return lower down (and the same with temperature? Before my "episode" I regarded myself as pretty fit and enjoyed high level hiking, often in desert areas.
