Evaluation Of Cardiac Function Before And After Percutaneous Cardiac Intervention For Patients With Non-ST Segment Elevation Cardiac Infarction By Tei Index In Combination With E/EM×Sm

Objectives: To measure Tei index,E/EM×Sm and relative indices of patients with non-ST segment elevation cardiac infarction(NSTEMI)by ultrasonic cardiogram,observe the evaluation of Tei index,E/EM×Sm and relative indices in cardiac function before and after percutaneous cardiac intervention,analyze the advantages of Tei index,E/EM×Sm and relative indices over traditional indices,so as to provide more reliable technical indices for clinical prognosis.Methods: We selected 62 patients for non-ST segment elevation cardiac infarction(NSTEMI)and received percutaneous cardiac intervention(PCI)in Department of Cardiology.We separately performed ultrasonic cardiogram 3 days before PCI,the day after PCI,and 1month after PCI.28 other patients who were in hospital,received coronary angiogram and exclude coronary heart disease in the same period were selected as the control group.Measure Tei index,E/EM×Sm and relative indices of ultrasonic cardiogram.Results: 1.Patients with NSTEMI had obviously abnormal Ventricular contractile and dilastolic function,compared to healthy people.2.Patients` cardiac function with NSTEMI were significantly improved after PCI,and the improvement in dilation function was earlier presented than that in systolic function.3.LVEF and E/A could not exactly evaluate the dilation function of patients with NSTEMI in short period after PCI.4.There was a strong correlation among Tei index,ICT and E/Em×Sm.Conclusions: There was a strong correlation among Tei index and E/Em×Sm.Compared with other traditional indices,Tei index and E/Em×Sm could be more reasonable,accurate and sensitive indicators to valuate the changes in cardiac function of patients with NSTEMI before and after PCI.
