| ObjectiveTo investigate the effects of the enhanced preoperative intervention for patients with coronary heart disease on PCI retated MI by(3-receptor blockers.Methods324 stable coronary heart disease patients who use Betaloc ZOK 23.75mg qd in long term and with heart rate above 70 beats per minute were randomly divided into 3 groups, depending on whether added β- blockers intensive treatment and intensive treatment dosage before PCI implementation:108 cases of the control group were not taking regular dose of β-blockers,108 cases of the intensive treatment group A were taking double dose preoperative,and another 108 cases of the intensive treatment group B taking triple dose preoperative. Respectively, before and six hours after the PCI all of cases were detected cTnI levels, observing incidence of PCI-related myocardial infarction.ResultsThe PCI-related myocardial infarction rate of both intensive treatment group A and B was statistically significant (P<0.05) than the control group. The PCI-related myocardial infarction rate of the intensive treatment group A and B showed no significant difference (P> 0.05).ConclusionsPreoperative enhanced β- blockers can significantly reduce the incidence of PCI-related myocardial infarction. |
