Heart Failure at High Altitudes

I am travelling this week in Mexico City, Mexico and the altitude of the city is 2240 meters (7,349 feet) above sea level.

I have not had too many problems dealing with this while sitting in meetings, but walking and climbing stairs cause the feeling that all heart failure patients know, the one where you feel a little tight in the chest because you are not getting enough oxygen.

Last night in bed, I experienced some breathlessness that I have not had for a good while and that was disturbing, of course.

All in all, it has not been too bad but I will be glad when I get home Friday night.
