RESUMO
Objective To observe the clinical efficacy of diltiazem in patients with coronary disease following percutaneous coronary intervention(PCI).Methods From Jan 2014 to Jan 2016,116 cases of coronary disease were selected as the research subjects,they were randomly divided into the observation group(62cases)and the control group(54 cases).The control group was given conventional therapy,while the observation group was given diltiazem therapy on the basis of control group.The levels of BP,HR,NT -proBNP,CRP and angina frequency in the two groups were compared before and 24h,48h after PCI.The incidence of major adverse cardiovascular events(MACEs) was assessed at the sixth month after PCI.Results After surgery,the CRP levels of the observation group and control group were (40.1 ±7.4)mg/L and (41.7 ±8.8)mg/L,the NT -proBNP levels of the two groups were (501.8 ± 56.5)ng/L and (445.7 ±50.6)ng/L,which were significantly higher than preoperation(t =5.684,P <0.05).The blood pressure,heart rate,CRP,NT -proBNP of the observation group since 24 hours after PCI were (73.1 ± 6.2)mmHg,(121.7 ±15.8)mmHg,(68.1 ±7.9)times/min,(24.8 ±3.7)mg/L,(201.7 ±20.6)ng/L,which were significantly lower than those of control group [(85.6 ±9.3 )mmHg,(134.3 ±17.4)mmHg,(77.5 ± 9.2)times/min,(36.5 ±7.9)mg/L,(481.5 ±48.2)ng/L].The effect was kept over 48 hours(F =7.281,8.097, 6.945,7.682,6.517,all P <0.05).Angina pectoris after treatment in the observation group and control group were (1.5 ±0.9)times/month,(2.9 ±0.7)times/month,which were significantly lower than before treatment(t =7.584,P <0.05).The incidence rate of total MACE in the observation group was 4.84%,which was significantly lower than that in the control group(χ2 =6.942,P <0.05).Conclusion Diltiazem after PCI can decrease the adverse reaction, and help to improve the prognosis of patients.
