Effects of Loading Dose Simvastatin on Related Indicators in PCI Perioperative Period of Patients with Acute Myocardial Infarction / 中国药房

ABSTRACT

OBJECTIVE:To explore loading dose simvastatin on related indicators in PCI perioperative period of patients with acute myocardial infarction. METHODS:Data of 203 acute myocardial infarction patients undergoing emergency PCI were retro-spectively collected and divided into observation group (102 cases) and control group (101 cases) by different regimens. Control group received conventional treatment for 3 d before PCI,including orally taking Aspirin enteric-coated tablet 300 mg/d,qd + Sim-vastatin tablet 40 mg/d,qd,simvastatin 40 mg/d after surgery,qd,for 4 weeks. Observation group received Simvastatin tablet 80mg 2 h before PCI,the other treatment was the same with control group. Total cholesterol(TC),triglyceride(TG),low-density li-poprotein cholesterol (LDL-C),high-density lipoprotein cholesterol(HDL-C),IL-6,IL-10,TFN-α,plasma super-sensitive tropo-nin(TNT-HSST)level,creatine kinase isoenzyme(CKMB)level,high sensitive C-reactive protein(hs-CRP)level and transami-nase level before and 24 h after treatment were observed and the incidence of adverse reactions was recorded. Meanwhile,the inci-dence of postoperative 30 d of MACE and CIN was followed-up. RESULTS:There was no significant difference in TG,TC, LDL-C,HDL-C before and after treatment(P>0.05). Before treatment,there was no significant difference in TNF-α,IL-6,IL-10, hs-CRP,CKMB,TNT-HSST levels in 2 groups (P>0.05);after treatment,TNF-α,IL-6,hs-CRP,CKMB,TNT-HSST levels were significantly higher than before(P<0.05),and TNF-α,IL-6,hs-CRP levels in observation group was significantly lower than control group,CKMB,TNT-HSST levels were significantly higher than control group;IL-10 was significantly lower than before in 2 groups,and observation group was higher than control group,with statistical significance (P<0.05). The MACE rate and CIN rate in observation were lower than control group with statistical significance(P<0.05). And no obvious adverse reaction was found in 2 groups. CONCLUSIONS:Loading dose simvastatin in PCI perioperative period can significantly reduce patients' PCI, TNF-α,hs-CRP,CKMB,TNT-HSST levels and the incidence of cardiovascular and renal adverse reactions.
