- 摘要:
- 目的 通过心电图早期识别下壁心肌梗死的病变血管是右冠状动脉(RCA)还是左回旋支(LCCA),为临床处理和预防并发症提供帮助。方法 对273例下壁心肌梗死患者的心电图Ⅱ,Ⅲ导联ST段比值(STⅡ/Ⅲ)和冠脉造影结果进行分析。结果 STⅡ/Ⅲ=1检测LCCA的特异度、敏感度、阳性预测值和阴性预测值分别为81%,97%,86%和96%;STⅡ/Ⅲ<1对检测RCA的敏感度、特异度、阳性预测值和阴性预测值分别为97%,91%,98%和89%;而STⅠ→检测LCCA的敏感度、特异度、阳性预测值和阴性预测值分别为75%,96%,82%和94%;STⅠ↓检测RCA的敏 感度、特异度、阳性预测值和阴性预测值分别为96%,81%,96%和84%。结论 这4种新方法对判断下壁心肌梗死相关血管的敏感度和特异度均较高,且简便实用。
- Abstract:
- AIM To recognize early whether the culprit artery is the right coronary artery (RCA) or left circumflex coronary artery(LCCA), so as to facilitate the management and, in some instances,the prevention of complications.METHODS We studied 273 consecutive patients with acute inferior wall myocardial infarctions who subsequently underwent coronary angiography. The principal investigator analyzed all the admission 12-lead electrocardiograms.RESULTS We found that STⅡ/Ⅲ=1 had a specificity of 81%,sensitivity of 97%,positive predictive value of 86%,negative predictive value of 96% for LCCA,whereas an isoelectric ST(STⅠ→) in leadⅠ had a specificity of 75%,sensitivity of 96%,positive predictive value of 82%,negative predictive value of 94% for LCCA. The criterion STⅡ/Ⅲ<1 had a sensitivity of 97%,specificity of 91%, positive predictive value of 98%,and negative predictive value of 89% for RCA,whereas ST depression (STⅠ↓) in leadⅠhad a sensitivity of 96%,specificity of 81%,positive predictive value of 96%,and negative predictive value of 84% for RCA.CONCLUSION These 4 criteria are useful in the recognition of infarction-related artery in inferior wall acute myocardial infarction, and more sensitive and specific than previously reported methods.
