目的探讨分析急性心肌梗死和急性心力衰竭血气指标的差异性,为治疗急性心肌梗死与急性心力衰竭提供理论依据。方法 50例急性心肌梗死患者为急性心肌梗死组,50例急性心力衰竭患者为急性心力衰竭组,比较两组血气指标的差异。结果两组二氧化碳分压(PCO_2)、呼吸指数(RI)、阴离子间隙水平(AG)、氧分压(PO_2)、pH、碱剩余(BE)、动脉血氧饱和度(SatO_2)、血乳酸(Lac)水平比较差异均有统计学意义(P<0.05)。结论急性心力衰竭组在PCO_2、RI、pH水平上高于急性心力梗死组;急性心力衰竭组在BE、Lac、PO_2、SatO_2、AG的水平上低于急性心肌梗死组。
Objective To investigate the differences of blood gas indexes between acute myocardial infarction (AMI) and acute heart failure and to provide a theoretical basis for the treatment of acute myocardial infarction and acute heart failure. Methods 50 patients with acute myocardial infarction were acute myocardial infarction group and 50 patients with acute heart failure were acute heart failure group. The differences of blood gas indexes between the two groups were compared. Results The changes of PCO2, RI, AG, PO_2, pH, BE, SatO2, Lac) levels were significantly different (P <0.05). Conclusions The levels of PCO2, RI and pH in acute heart failure group are higher than those in acute myocardial infarction group. The levels of BE, Lac, PO_2, SatO_2 and AG in patients with acute heart failure are lower than those in acute myocardial infarction group.
