NCT05554484

Brief Summary

The purpose of this trial is to assess the safety of AMI-DC treatment. The participants who voluntarily sign the consent form will be screened according to the inclusion/exclusion criteria then allocated either to the experimental group (drug therapy and AMI-DC therapy) or to the control group (drug therapy only). Both the experimental group and the control group are treated with standard medical therapy after PCI. The experimental group will be hospitalized for 4-5 days after 1st injection, and 1 day after 2nd injection. Vital signs are collected after 30 minutes, 1 hour, 2 hours and 4 hours after the 1st and 2nd injections and the subjects will be monitored 24 hours for safety assessment. The identical examination will also be performed in the control group and the results will be collected.
