Abstract
The essence of the phenomenon of ischemic preconditioning is increasing myocardium resistance to long periods of ischemia that occurs after several short ischemia-reperfusion periods. The aim of this pilot study was to determine the temperature and vascular response in double brachial occlusions and to assess the prospects of using this maneuver for remote ischemic preconditioning. Infrared thermography-based measurements were used to assess hemodynamics both left and right hands during the baseline, ischemia and hyperemia periods. Double ischemia with a period of 2 min was implemented by a cuff compression of the brachial artery of the right hand. A study group was constituted of eight men and six women without cardiovascular abnormalities at the age of 22 to 35 years. As a result, we have determined that a temperature and vascular response to ischemia of right hand is accompanied by the vascular reaction of the contralateral left hand, especially after the inflation and deflation of the cuff. These vascular reactions are reproducible, systemic and appear to be at least neurological in nature. An experimental confirmation of the systemic vascular «training effect» after multiple brachial ischemia-reperfusion periods is a subject of further investigations.
