The core group of Mayo Clinic researchers that moved their lab to the base camp at Mount Everest to study heart disease and aging are at it again, this time in Africa. Along with a party of nearly 35, they will be climbing Mt. Kilimanjaro, obtaining scientific data from the climbers along the way.
Led by Mayo physiologist Bruce Johnson, Ph.D. and joined by Amine Issa, Ph.D., Courtney Wheatley, Ph.D., and Jan Stepanek, M.D., among others, the group will monitor climbers’ heart rates, oxygen saturation, movement, energy expenditure, skin temperature and the quality of their sleep. They’ll also conduct ultrasound scanning to determine differences in younger and older climbers as they react to the altitude.
“It’s about comparing heart and lung function in this natural laboratory,” says Dr. Issa, who was part of the group on Everest. “We want to check on limitations to their functioning and whether or not a vitamin B3 supplement can help them.” Read: "Mayo Clinic Takes Medical Research to Kilimanjaro" on Advancing the Science blog.
