Abstract:
Objective To investigate the relationship between QRS wave terminal distortion with coronary arterial lesion and serum high-sensitivity cardiac troponin I (hs-cTnI) in early stage of acute ST-segment elevation myocardial infarction (STEMI).Methods One hundred and twenty patients with STEMI were classified into the QRS wave distortion positive group(QRS+,n=81) and non-QRS wave distortion group(QRS-group,n=39) according to EKG on admission.The two groups all conducted the coronary angiography and hs-cTnI detection.The coronary arterial lesion occurrence situation and hs-cTnI level were compared between the two groups.Results (1) In the QRS+ group:68 cases (83.59％) were male and 13 cases (16.05％) were females;in the QRS-group:27 cases(69.23％) were male and 12 cases (30.77％) were female.The sex difference had statistical significance (P＜0.05).(2) The occurrence rate of left anterior descending artery (LAD) lesion in the QRS+ group was higher than that in the QRS-group,the difference was statistically significant (P＜0.05).But the occurrence rate of left circumflex coronary artery (LCX) lesion in the QRS-group was higher than that in the QRS+ group,the difference was statistically significant (P＜0.01).(3) The hs-cTnI level in the QRS+ group was higher than that in the QRS-group,the difference was statistically significant (P ＜0.01).Conclusion The patients with QRS wave distortion positive have a higher occurrence rate of LAD lesion,while the patients with out QRS wave distortion negative have higher occurrence rate of LCX lesion;the QRS wave terminal distortion has relationship with serum hs-cTnI level.
