Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The experimental group measured upright blood pressure 90 days after startup and evaluated the changes in upright blood pressure compared to baseline;Differences in changes in upright blood pressure compared to baseline between the experimental group and the control group at 90 days after startup; | — |
Secondary
| Measure | Time frame |
|---|---|
| The difference between the upright position blood pressure measured at 90 days after startup in the experimental group and 90 days after enrollment in the control group and the baseline walking distance measured at 90 days after startup in the experimental group and 90 days after enrollment in the control group;Differences in the number of syncope episodes per week between the experimental group and the control group at 90 days after startup compared to baseline;The difference in the number of weekly changes in pre syncope status between the experimental group and the control group at 90 days after startup compared to baseline;Differences in blood pressure variability of blood pressure between the experimental group and the control group at 90 days after startup compared to baseline;Differences in heart rate changes compared to baseline between the experimental group and the control group at 90 days after startup;Differences in changes in the daily living ability assessment scale (ADL) between the experimental group and the control group at 90 days after startup compared to baseline; | — |
