About this study

According to the latest survey data of China hypertension annual meeting, there are about 300 million patients with hypertension in China, with 10 million new cases of hypertension each year, and there is an obvious trend of younger people. In particular, young and middle-aged people are in a state of mild hypertension for a long time, which causes great pressure on health and medical treatment. At present, the main clinical measures for mild hypertension are to change their eating habits, quit smoking and alcohol, exercise and other lifestyle changes, as well as drug control. For most patients with mild hypertension, drug control is not the best choice. It has been reported that remote ischemic preconditioning (RIPC) may play an effective role in reducing blood pressure .The purpose of this study was to investigate the extent of long-term application of RIPC to reduce blood pressure in patients with mild hypertension.

Read the detailed description

A total of 200 patients with mild hypertension were enrolled in this study, using the method of open label and parallel grouping; 100 cases in the experimental group and 100 cases in the control group, The experimental group was divided into life intervention + drug group and life intervention + ripc group, with 50 patients in each group. The results of 24-hour ambulatory blood pressure monitoring (ABPM) of the three groups were observed before and 3 months after use, including HR, pulse pressure, 24-hour systolic blood pressure, 24-hour diastolic blood pressure, daytime systolic blood pressure, daytime diastolic blood pressure, nighttime systolic blood pressure and nighttime diastolic blood pressure. The changes of renalase, catecholamine, renin, angiotensin - Ⅱ, aldosterone, RhoA kinase, no, adenosine and bradykinin were observed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CRICDevice

    Remote Ischemic Conditioning (CRIC): Twice daily for 12 weeks using an automated cuff device. Each 30-minute session consisted of 3 cycles of 6 min inflation (pressure individualized: resting SBP-based increments of +40/+30/+20 mmHg depending on baseline SBP level) followed by 4 min deflation (0 mmHg).

  • MFTBehavioural

    Sham CRIC: Identical schedule and device; each cycle used fixed 5 min inflation at 60 mmHg (non-ischemic) followed by 5 min deflation.

  • sham CRICOther

    Sham CRIC: Identical schedule and device; each cycle used fixed 5 min inflation at 60 mmHg (non-ischemic) followed by 5 min deflation.

  • sham MFTOther

    Sham MFT: Twice daily equivalent-duration audio of looped neutral nature sounds (ocean waves, flowing water, birdsong) without mindfulness instructions.
