Effects of liraglutide intervention combined with PCI therapy on ventricular remodeling and cardiac function in patients with acute myocardial infarction and type 2 diabetes mellitus

Abstract

Objective To analyze the influence of liraglutide intervention combined percutanous coronary intervention(PCI) therapy on acute myocardial infarction(AMI) with type 2 diabetes(T2DM) patients′ myocardial injury, ventricular remodeling(VR), and cardiac function. Methods Eighty patients with AMI and T2DM were included in the study, and they were randomly divided into observation group and control group according to the random number table, each with 40 patients. The patients in the control group received metformin and conventional insulin combined PCI treatment, and the patients in the observation group received metformin and liraglutide combined PCI treatment. The changes in the values of ventricular remodeling indexes, cardiac function and serum related indexes were compared after 3 months treatment between the two groups. Results (1)The body weight and fasting blood glucose levels of the observation group were significantly lower than those of the control group(P<0.05), and fasting insulin levels were significantly higher than those of the control group(P<0.01). (2)The levels of N-terminal-pro-B-type natriuretic peptide(NT-proBNP), creatine kinase isoenzymes-MB(CK-MB), and troponin I(TnI) in the observation group 3 months after treatment were significantly lower than those in the control group(P<0.05). (3)The levels of serum hypersensitive C-reactive protein(hs-CRP), tumor necrosis factor-α(TNF-α), and interleukin-6(IL-6) in the observation group were significantly lower than those in the control group 3 months after treatment(P<0.05). (4)The values of left ventricular end systolic diameter(LVESD), left ventricular end diastolic diameter(LVEDD), interventricular septum thickness(IVST), left ventricular posterior wall thickness(LVPWT), left ventricular mass index(LVMI), left ventricular end systolic volume(LVESV), and left ventricular end diastolic volume(LVEDV) in the observation group were lower than those in the control group; the values of left ventricular fraction shortening(LVFS), left ventricular ejection fraction(LVEF), and mitral valve early diastolic blood flow rate(VE)/atrial systolic flow velocity(VA), all were higher than those of the control group(P<0.05). Conclusion Lraglutide intervention combined with PCI therapy on AMI with T2DM patients may reduce myocardial injury, induce ventricular remodeling, enhance cardiac function, and improve prognosis.
