Essential Hypertension
Conditions
Brief summary
The purpose of this study is to learn about effects of remote ischemic conditioning on blood pressure in older patients with essential hypertension.
Detailed description
Current studies have shown that remote ischemic conditioning can improve vascular endothelial function and inhibit sympathetic nervous system activity. Thus it may provide some organ protection as well as anti-hypertensive effects. The purpose of this study is to learn about effects of remote ischemic conditioning on blood pressure in older patients with essential hypertension.
Interventions
PROCEDURERemote ischemic conditioning
Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by the inflation of an automated cuff to the pressure rising by 20 mmHg from baseline systolic pressure. RIC will be conducted twice daily for 7 days.
PROCEDURESham remote ischemic conditioning
Sham-RIC is performed in the same way as the treatment group except that the blood pressure cuff is inflated to 60 mmHg, which produces mild pressure sensations but has no blocking impact on blood flow.
