Abstract

Background: It is still very controversial whether the characteristics of pain in the acute myocardial infarction could be related to the culprit coronary artery. There are no data about associations of pain with the ST-segment elevation myocardial infarction (STEMI) and left ventricular (LV) fibrotic segments.

Methods: Data from 328 participants who had STEMI and were included in the B and T Types of Lymphocytes Evaluation in Acute Myocardial Infarction (BATTLE-AMI) study were analyzed. The culprit artery was identified by coronary angiography and the injured myocardial segments by cardiac magnetic resonance. The statistical significance was established by P value < 0.05.

Results: A total of 223 patients (68%) were selected. Association was not observed between chest pain and the culprit artery (P = 0.237), as well as between pain irradiation and the culprit artery (P = 0.473). No significant difference was observed in the pain localization in relation to the segments in the short axis basal, mid, apical, and long axis, except for the mid inferior segment. The data were not considered clinically relevant because this association was observed in only one of 17 segments after multiple comparisons.

Conclusions: In patients with STEMI, no associations were observed between the location or irradiation of acute chest pain and/or adjacent areas and the culprit artery, or between pain and segmental myocardial fibrosis in the LV.

急性心肌梗死胸痛及其与心脏磁共振鉴定的罪魁动脉和纤维化段的关系。

背景:急性心肌梗死的疼痛特征是否与罪魁祸首冠状动脉有关，目前还存在很大争议。没有关于疼痛与st段抬高型心肌梗死(STEMI)和左心室(LV)纤维化段相关的数据。方法:对328名STEMI患者的数据进行分析，这些患者被纳入急性心肌梗死B型和T型淋巴细胞评估(BATTLE-AMI)研究。通过冠状动脉造影和心脏磁共振检查确定了损伤的心肌节段。P值< 0.05为差异有统计学意义。结果:共入选223例(68%)。胸痛与罪魁动脉无相关性(P = 0.237)，疼痛照射与罪魁动脉无相关性(P = 0.473)。除中下节段外，短轴、基轴、中轴、尖轴和长轴节段的疼痛定位无显著差异。这些数据不被认为具有临床相关性，因为在多次比较后，在17个节段中仅观察到这种关联。结论:在STEMI患者中，急性胸痛和/或邻近区域的位置或照射与罪魁动脉之间，或左室疼痛与节段性心肌纤维化之间没有关联。
