Role of high temperature magnetocardiography in diagnosis of unstable angina pectoris
Abstract：Objective To study the efficiency and possibility of high-temperature magnetocardio-graphy (HT-MCG) in diagnosis of unstable angina pectoris (UAP) .Methods Sixty coronary an-giohraphy (CAG)-diagnosed UAP patients served as an UAP group and 58 patients with no sig-nificant coronary stenosis served as a control group in this study .The patients underwent HT-MCG .A map of current density distribution was plotted during the ST-T stage at an interval of 12 ms .The average classification of total map (ACTM)and the ratio of abnormal map (RAM) were used as the observation indications .Results The ACTM and RAM were significantly higher in UAP group than in control group (3 .12 ± 0 .84 vs 1 .56 ± 0 .92 ,69 .43 ± 25 .58 vs 37 .14 ± 20 .75 , P<0 .05) .The sensitivity of HT-MCG was significantly higher than that of electrocardiography and echocardiography in diagnosis of UAP (81 .7% vs 66 .7% and 45 .0% ) .Conclusion The value and sensivity of HT-MCG are higher than those of electrocardiography and echocardiography in diagnosis of UAP .
