Abstract:Objective To investigate the influence of modified PCI interventional therapy on relative index and perioperative complications in patients with acute ST segment elevation myocardial infarction (STEMI). Methods Totally 110 patients with acute STEMI admitted to our hospital from October 2013 to October 2015 were involved in this study. Patients were randomly divided into control group which received standard treatment of PCI (n = 55) and observation group which received modified PCI treatment (n = 55). Operation time, time of D2B, time of C2B, time of X-ray, incidence of radial artery spasm, amount of contrast agent, intraoperative complication rate, incidence of MACE postoperatively were recorded. Results Time of D2B, C2B, C2B operation, and X-ray in the observation group were decreased significantly compared with control group (P < 0.05). Incidence of radial artery spasm and amount of contrast agent used during surgery in the observation group were lower dramatically than those in the control group (P < 0.05). No significant difference in incidence of intraoperative complication and follow-up MACE in the two groups was identified (P > 0.05). Conclusion Modified PCI interventional therapy significantly shortens time of duration of surgery, and reduces the incidence of radial artery spasm and usage of contrast agents.
