Abstract
ObjectiveTo investigate the recent influence of intensity-modulated radiotherapy (IMRT) in middle or lower esophageal carcinoma on heart. Methods20 patients confirmed esophageal carcinoma under paragraph radical conformal IMRT were selected, respectively, received electrocardiogram, myocardial enzymes, troponin, echocardiography in the week before radiotherapy and radiotherapy week. Results The serum lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotransferase (AST), kinase (CK), kinase isoenzyme (CK-MB), high-sensitivity troponin (cTnI) before and after radiotherapy was not changed significantly (P>0.05); the former was greater than the rate of ECG abnormalities after radiotherapy radiotherapy, the difference was statistically significant (P<0.05); before and after radiotherapy LA, LVD, LVEF did not change significantly (P>0.05). ConclusionLower esophageal radiotherapy-induced or induced myocardial injury early is not obvious, mainly in the ECG changes, and myocardial enzymes, troponin, echocardiography and other related indicators change is not obvious.关键词
