There already have had some researchers found the phenomenon of lowing blood pressure among heart failure patients and pre-hypertensive individuals after a long-term of ischemic conditioning therapy. However, there's still lack of specific clinical trials carried out to confirm itspotential treatment effect of lowing blood pressure.
The investigators designed this randomized, doubleblind, controlled clinical trial to examine (1) whether RIC has a beneficial effect on blood pressure; (2) whether RIC exert its protection effect through immunological regulation. There are 2 arms in this trial: One arm is RIC treatment, the other one is sham RIC treatment. Blood pressure will be measured by ambulatory blood pressure monitoring before and after the treatment to evaluate its exact effect on BP. Also, circulatory immunological factors will be tested before and after the treatment to illustate whether immunological regulation involved in the process.
