Abstract:Objective To investigate the influence of dual antiplatelet therapy on prognosis of patients with recurrent myocardial infarction after coronary stent impantation. Methods Fifty-two cases of patients with recurrent myocardial infarction after coronary stent implantation admitted to Department of Cardiology, the First Affiliated Hospital of China Medical University from January 2014 to June 2015 were selected and randomly divided into control group and study group, with 26 cases in each group. The control group was treated with Aspirin 100 mg, and the study group was treated with Aspirin 100 mg and Clopidogrel 75 mg, total treatment for 12 months. Through blood collection, the indexes of hemorheology, cardiac troponin I (cTnI) and brain natriuretic peptide (BNP), inflammatory mediators and matrix metalloproteinases were detected before and after treatment for 12 months. Results Compared with those before treatment, the contents of blood viscosity, plasma viscosity and plasma fibrinogen were decreased significantly (P < 0.05), the contents of cTnI and BNP were decreased significantly (P < 0.05), the contents of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were decreased significantly (P < 0.05), and the contents of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) were decreased significantly (P < 0.05). Compared with those of control group, the contents of blood viscosity, plasma viscosity and plasma fibrinogen in the study group were significantly lower (P < 0.05), the contents of cTnI and BNP were significantly lower (P < 0.05), the contents of CRP, TNF-α and IL-1 were significantly lower (P < 0.05), and the contents of MMP-2 and MMP-9 were significantly lower (P < 0.05). Conclusion For patients with recurrent myocardial infarction after coronary stent implantation, intensive dual antiplatelet therapy can decrease the contents of serum cTnI and BNP, improve hemorheology and inflammatory state, and promote the prognosis.
