Influence of intravenous injection combined with oral of metoprolol tartrate on left ventricular function and adverse cardiovascular events of patients with acute anterior myocardial infarction
Objective To explore the influence of intravenous injection combined with oral of metoprolol tartrate on left ventricular function and adverse cardiovascular events of patients with acute anterior myocardial infarction.Methods84 cases of Patients with acute anterior myocardial infarction treated in the First Hospital of Hebei Medical University were selected as the study objects, and were divided into vein group and combination group according to drugs-taking modes, 42 cases in each groups.The vein group were treated with intravenous injection of metoprolol tartrate, and the combination group were treated with intravenous injection combined with oral of metoprolol tartrate.Clinical effect, left ventricular function, BP and HR levels, and incidence of adverse cardiovascular events were observed in the two groups.ResultsThe total effective rate of the combination group was 95.24% significantly higher than that of 80.95% in the vein group(P<0.05).After treatment, LVEF was significantly higher than that before treatment in the two groups (P<0.05), which of the combination group was significantly higher than that of the vein group (P<0.05).The levels of LVESD and LVEDD were significantly lower than those before treatment in the two groups (P<0.05), which of the combination group were significantly lower than those in the vein group(P<0.05).After treatment, DBP, SBP and HR were significantly lower than those before treatment in the two groups (P<0.05), which of the combination group were significantly lower than those in the vein group(P<0.05).The incidence of adverse cardiovascular disease was 11.90% in the combination group, and it was no significantly different from that of 16.67% in the vein group (P>0.05).ConclusionIntravenous injection combined with oral of metoprolol tartrate can effectively improve left ventricular function of patients with acute anterior myocardial infarction, and reduce incidence of adverse cardiovascular events.
