The Relationship Between Electocardiographic Changes With Different Types Of Acute Coronary Syndrome And Clinical Risk Factors

Objective: To study the ST-T changes in different types of ACS patientsand the relationship with Coronary angiography；To study the different types ofacute coronary syndrome (ACS) patients age,sex,hypertension,diabetes，dyslipidemia and Smoking histories between its relationship and clinicalsignificance.Methods: To select two hundred and seventy-four patients with acutecoronary syndrome, which were hospitalized in department of Cardiology,Affiliated Hospital of Guilin Medical University between October2011and june2012. They were somatotyped according to standard for ACC/AHA2005, whichwere measured age and sex,hypertension,diabetes,dyslipidemia,smokinghistory,ST-segment elevation,ST-segment depressed of guide groupnumber,amplitude and coronary angiography with involving the lesionscount,coronary artery stenosis of correlation. According to the ACS somatotypewhich are divided into three groups for unstable angina pectoris (UAP),nonST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardialinfarction (STEMI)；Compare with the relationships during three groups inage,sex,hypertension,diabetes,dyslipidemia,smoking history. According to the ST-segment elevation of guide group number and amplitude, Compared withSTEMI ST-segment elevation of guide group number and amplitude between theCoronary angiography lesions count and Coronary angiography stenosis degree.Compared with NSTEMI ST-segment depressed of guide group number andamplitude between the Coronary angiography lesions count and Coronaryangiography stenosis degree according to the ST-segment depressed of guidegroup number and amplitude.Results:①NSTEMI group multivessel disease is obviously higher than theSTEMI group and UAP group with a significant difference(P<0.01); UAP groupof coronary artery stenosis is less than the NSTEMI group and STEMI groupwith a significant difference(P<0.01); There was no significant difference withthe coronary artery stenosis between the STEMI group and NSTEMIgroup(P>0.05); But STEMI group100%-block rate is obviously higher than thatof the NSTEMI group with a significant difference(P<0.01).②ST-segmentdepression of degree,ST segment depressed of guide group numberwere positively related with Coronary lesions count(r=0.393,0.368) andCoronary stenosis degree(r=0.306,0.313)(P<0.01).③ST-segment elevation ofdegree were positively related with Coronary lesions count(r=0.287)andCoronary stenosis degree(r=0.360)(P>0.05); ST-segment elevation of guidegroup number were not positively related with Coronary lesions count(r=-0.004)and Coronary stenosis degree(r=0.145)(P>0.05).④There were no significantdifferences with in age, hypertension， high cholesterol and smokinghistory(P>0.05)；Yet there is a significant difference with NSTEMI group ofdiabetes than STEMI group and UAP group(P<0.05); And STEMI group isobviously higher than male NSTEMI group and UAP group with a significantdifference(P<0.01). Conclusions: NSTEMI ST segment depressed guide group, the more thegreater the amplitude, the occurrence probability of coronary multivessel disease,also the greater the degree of stenosis is more serious; STEMI ST-segmentelevation the amplitude of the coronary artery multivessel disease the occurrenceprobability, also the greater the degree of stenosis is more serious;NSTEMIpatients with multivessel coronary artery disease and diabetes are more thanSTEMI patients and UAP patients.
