Changes in diastolic blood pressure at T1-T3 in the three groups of patients, there was no statistically significant difference in diastolic blood pressure in the three groups (P>0.050). During the period of T2 and T3, the diastolic blood pressure in the rehabilitation training group and the nursing intervention group were lower than the control group, and the difference was statistically significant (P<0.050). There was no significant difference in diastolic blood pressure between the rehabilitation training group and the nursing intervention group (P>0.050). The diastolic blood pressure at T3 among the three groups was significantly lower than both T2 and T1. The diastolic blood pressure at T2 was lower than T1, and the difference was statistically significant (P<0.050). ^P<0.050, the difference is statistically significant compared with the control group; *P<0.050, the difference is statistically significant compared to T1; #P<0.050, the difference is statistically significant compared to T2.
