Abstract
Objective To investigate the relationship between myocardial repolarization electrocardiogram and the prognosis of coronary heart disease. Methods 98 Patients with coronary heart disease were selected from October in 2014 to October in 2016 in our hospital. They were divided into good prognosis group, poor prognosis group and the death group. Abnormal index of myocardial repolarization including number of ST segment of low lead, morphological variation of T wave ( TMD), QT interval ( QTc) and QT dispersion (QTd) were recorded. Nt-Pro BNP levels were detected and the prognosis was observed. Cox regression analysis was done. Results In poor prognosis group and death group number of ST segment of low lead, TMD, QTc and QTd were significantly higher than those in good prognosis group. Number of ST segment of low lead, TMD, QTc and QTd in the death group were signifi-cantly higher than those in poor prognosis group. Number of ST segment of low lead, TMD, QTc, QTd of all patients were positively correlated with NT-pro BNP levels (P<0.05). Age, BNP levels, number of ST segment of low lead, TMD, QTc and QTd were the risk factors of poor prognosis of coronary heart disease (CHD) with heart failure. Conclusion The assessment of abnormal myo-cardial repolarization parameters were useful in predicting prognosis for patients with CHD with heart failure.关键词
