摘要

目的:本研究的目的是评估急性入院的不稳定型心绞痛或非ST段抬高型心肌梗死(NSTEMI)患者PR间期延长与严重冠状动脉疾病(CAD)之间的关系。背景:心电图PR间期延长在临床实践中经常发生。迄今为止,很少有研究评估NSTEMI和不稳定型心绞痛住院患者PR间期延长与显著CAD之间的关系。方法:对205例NSTEMI或不稳定型心绞痛患者的PR间期进行测量,将患者分为PR间期正常(<200ms)和延长(≥200ms)。我们在所有患者住院后48-72小时内进行了超声心动图和冠状动脉造影。结果:96例(46.8%)患者PR间期延长(%(>([0-9]+)200ms)。这一发现与显著的CAD有统计学意义(P=0.024)。此外,这些患者有更高的Gensini评分(P=0.093)和更高的左主冠状动脉或三血管CAD频率(P=0.069)的趋势。结论:我们的研究表明,与早期的信念相比,延长PR间期与急性冠状动脉综合征患者的显著CAD独立相关。

Association between prolonged PR intervals and significant coronary artery disease in patients with non-ST elevation myocardial infarction and unstable angina
Objectives: The purpose of this study was to assess the association between a prolonged PR interval and significant coronary artery disease (CAD) in patients who were acutely admitted with unstable angina or non-ST-segment elevation myocardial infarction (NSTEMI). Background: Prolongation of the electrocardiographic PR interval occurs frequently in clinical practice. Few studies to date have evaluated the association between prolonged PR intervals and significant CAD in hospitalized patients with NSTEMI and unstable angina. Methodology: PR interval was measured in 205 patients with NSTEMI or unstable angina, and the patients were divided into those with normal (< 200 ms) and prolonged PR interval (≥200 ms). We performed echocardiography and coronary angiography within 48–72 h after hospitalization in all patients. Results: A prolonged PR interval (%(>([0-9]+)200 ms) was present in 96 patients (46.8%). This finding was statistically significantly associated with significant CAD (P = 0.024). In addition, these patients had a trend toward higher Gensini scores (P = 0.093) and a higher frequency of left main coronary artery or three-vessel CAD (P = 0.069). Conclusion: Our study showed that a prolonged PR interval is independently associated with significant CAD in patients with acute coronary syndrome, in contrast with earlier beliefs.
