| Objects To compare and study the characteristics of 12-lead ecg in stress cardiomyopathy and acute anterior wall myocardial infarction,to provide clinical value for further improving the accuracy of early diagnosis of two diseases.Methods The 100 patients with acute chest pain were divided into two groups,including 50 patients with irritable cardiomyopathy and 50 patients with acute anterior wall myocardial infarction.An electrocardiogram(ecg)was performed on 100 selected patients by a skilled medical staff with a 12-lead synchronous ecg machine.The subjects were recorded in the body table of the 12 leading ecg,and the pathological Q wave and T wave were compared and studied according to the various leading ST segments recorded in the electrocardiogram.The general conditions,stress factors,clinical manifestations and prognosis of the two diseases were compared,and the combined classification and statistical analysis were conducted according to statistical methods.Both patients underwent cardiac ultrasound,coronary angiography,and myocardial enzyme examination during admission.Compare the differences in the results of auxiliary examinations except ecg.Result1.Baseline comparison:Stress cardiomyopathy with acute anterior wall myocardial infarction in gender and stress induced factors are significantly different(P < 0.01),while there was no significant difference between the average onset age of the two kinds of disease,no statistical significance.2.Auxiliary inspection:Stress cardiomyopathy in 85% of patients in cardiac echocardiography and left ventricular angiography of apex of spherical expansion,the left ventricle is a typical "octopus basket" appearance change,after a period of time(a few days or weeks)can be returned to normal;There was no obvious abnormality in coronary angiography.In patients with acute anterior wall myocardial infarction,cardiac ultrasonography can be seen to be abnormal in segmental activity,and coronary angiography showed severe stenosis or occlusion.3.Comparison of ecg.(1)on the distribution of ST segment elevation lead,lead wall under stress cardiomyopathy distribution ratio is significantly higher than acute anterior wall myocardial infarction(mi),and significantly lower than in V1 lead acute anterior wall myocardial infarction(ami)and two diseases comparative difference was statistically significant(P <0.01).Acute anterior wall myocardial infarction was significantly less than that of stress cardiomyopathy(P<0.01).(2)the incidence of pathological Q wave in acute anterior wall myocardial infarction was significantly higher than that of stress cardiomyopathy,and the difference was statistically significant(P<0.01).(3)most of the acute anterior wall myocardial infarction had a mirror change,and there was almost no presence in the stress cardiomyopathy,and the difference was statistically significant(P<0.01).Conclusion Stress cardiomyopathy patients often causes diseases due to mental or physical stimulation,attack symptoms similar to acute coronary syndrome,with sudden,transient,reversibility and other characteristics,easily misdiagnosed as acute myocardial infarction.As the most convenient,simple and extensive 12-guide synchronous ecg,it can be applied at the bedside of the patient as soon as possible.And stress cardiomyopathy characteristics of electrocardiogram(ecg)and acute anterior wall myocardial infarction obvious difference,if we can master the different ecg findings,early differential diagnosis of two kinds of disease have a certain value,especially in acute stage,is very important to choose whether to use reperfusion therapy.In addition,it is of great significance to provide correct diagnosis and treatment,shorten the course of disease,improve the survival rate and long-term prognosis,combined with clinical manifestations and imaging features. |
