| Objective: To investigate the myocardial protective effect of remote ischemic preconditioning(RIPC)on patients undergoing selective coronary intervention(PCI).Method: Eighty-three patients who underwent coronary intervention in the Hospital from July 2019 to June 2020 were selected.Fifty-two patients were randomly selected as the experimental group and underwent remote ischemic preconditioning,i.e.,24 hours before PCI,unilateral upper limbs were bound with a sphygmomanometer cuff and pressurized to 200 mm Hg or 50 mm Hg higher than the systolic pressure.The remaining 31 patients were the control group,and the cuff of the sphygmomanometer was pressurized to 20 mm Hg.Both groups were inflated for 5 minutes and deflated for5 minutes,with 3 consecutive cycles.The levels of troponin I(c Tn I),creatinine(Scr)and cystatin C(Cys C)before and after operation and the incidence of adverse cardiovascular events(MACE)within 3 months were compared between the two groups.Result: PCI postoperative rise trend of troponin I in the experimental group is lower than the control group(0.51VS0.325),differences matter(p =0.042),the experimental group after creatinine level is lower than the control group(71vs76),differences matter(p = 0.031),the experimental group of postoperative bladder inhibition C level is lower than the control group(0.98VS1.07),difference matter(p = 0.029).Kaplan-Meier survival curves showed a statistically significant reduction in the incidence of adverse cardiovascular events in the experimental group compared with the control group at 3months of follow-up(p=0.026).Conclusion: Remote ischemic preconditioning has a protective effect on the heart and kidneys of patients undergoing elective PCI,and can reduce the incidence of adverse events within 3 months after surgery. |
