Treadmill Exercise Test And ASMPI For Diagnosis And The Lesion Location Of Stable Angina Pectoris

Objective: For stable angina examination (stable angaina pectoris SAP) patients,grouping flat test line movement (treadmill exercise test TET) and adenosine adenosine(ADE) load nuclide perfusion myocardial imaging (myocardial perfusion imagimg MPI),two groups of patients during the same period (two weeks) line of coronary angiography(coronary angiography the CAG), to the CAG as the gold standard, analysis of two kindsof inspection method for the qualitative diagnosis value of SAP, TET ecg ST segmentchanges and adenosine stress MPI positioning value for SAP.Methods: All the selected patients were suspected in patients with SAP, symptomsin2006the European society of cardiology (ESC) guidelines of diagnosis and treatmentof SAP, and according to the inclusion criteria and exclusion criteria to choose betweenJanuary2013and February2013in yenan university hospital heart SAP examination ofpatients with a total of80cases, were randomly divided into motion tablet and nuclidegroup,40cases in each group of patients. Line of TET and adenosine stress MPIrespectively. Two groups of patients were in the same period the CAG examination (twoweeks). Record motion tablet experiments lead electrocardiogram (ecg) in patients withST segment changes and the result of adenosine stress myocardial imaging nuclideperfusion, and crown made the results compared with the same period. This study datausing SPSS statistical software package processing (17.0), expressed as a percentagecounting data, mean±standard deviation (x__±s) measurement data. Count data bychi-square test, measurement data using two independent sample t test, when P acuitieswere o.05think the difference was statistically significant.Results：1.TET ECG ST segment changes in the diagnosis of SAP, the positive predictivevalue was84%, the negative predictive value was25%, the sensitivity was82%,specificity of29%, accuracy of73%, TET ECG ST segment changes for the diagnosis of SAP and the gold standard CAG, with no statistical difference.2.TET ECG ST segment changes affected by the degree of coronary stenosis in thediagnosis of SAP, mild and severe lesions of TET ST segment of ECGdiagnosis of SAPhad significant difference (P≤0.05).3gender differences in the TET of ST segment of ECG in the diagnosis of positivefor SAP (P≤0.05), TET were higher than that of female patients in male patients, thesensitivity and accuracy.4LAD lesions TET ECG ST segment changes in lead V1-V6frequency wassignificantly higher than the other lead (P≤0.05). In lead V1-V6, V4-V6frequency ishigher than V1-V3(P≤0.05). TET ST segment of ECG.5.LCX changes occurred in Ⅰ, Ⅱ, down III, avF, avL, V1-V3, compared with otherleads the difference was significant (P=0.05).6. II III avF lead change prediction of lesions in the RCA.7.LAD+LCX treadmill exercise test ECG ST segment changes occurred in the avL Ⅰ,Ⅱ, Ⅲ,, avF, V4-V6were higher than those of other lead (P≤0.05). The lesions werelocated in the LAD+RCA ST segment of ECG changes occurred in the lead of thefrequency had no significant difference (P≥0.05). The lesions were located in theLCX+RCA ST segment of ECG changes occurred in the lead of the frequency had nosignificant difference (P≥0.05). LAD+LCX+RCA, which leads to change in thefrequency of V3-V6was100%.8.LM lesions of the treadmill exercise test ECG ST changes were found in V1-V6.The positive predictive.9adenosine MPI qualitative diagnosis of SAP value was92%, the sensitivity was88%,the negative predictive value was80%, the specificity was85%, the accuracy was86%.10.adenosine MPI on SAP in mild and severe stenosis had a significant difference (P≤0.05).11adenosine MPI on SAP positioning diagnosis ofstenosis, location consistent withthe rate of88%.Conclusions：1. TET to SAP is simple, high security and high accuracy of noninvasive examination method, but its diagnosis of SAP is in patients with coronary artery stenosisdegree, parts and gender.2. TET ecg ST segment changes and the SAP patients associated blood vessels"criminals" to a certain extent, can provide the basis for SAP lesion location.3. The nuclide perfusion of adenosine stress myocardial imaging lesion location andthe CAG results degree is high, can determine the blood vessels "criminals". The MPI inthe diagnosis of SAP also affected by the degree of coronary artery lesions.4. TET electrocardiogram (ecg) if you can combine the MPI can be used as diagnosisand judgment of SAP for reascularization, and provides the basis for looking for"criminals" vessels and prognosis.
