Acute myocardial infarction (AMI) has a high mortality rate and poor prognosis for patients. The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction (TIMI) risk score, which can be used to predict the prognosis and the need for revascularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance. Fragmented QRS (fQRS) has been shown to be a valuable electrocardiographic (ECG) index for predicting the prognosis of patients with coronary heart disease. Also, fQRS is considered to predict an increased likelihood of a poor outcome and mortality in patients with coronary artery disease (CAD), even for some successfully revascularized AMI patients. So what would happen if fQRS and the TIMI risk score were combined? This study focused on the investigation of the short-term prognostic value of fQRS combined with the TIMI risk score for patients with AMI.
急性心肌梗死（AMI）患者死亡率高，预后差。死亡的主要原因是心律失常和心力衰竭。对于因心肌梗死入院的患者，会启动各种风险评估以预测可能的并发症。溶栓治疗心肌梗死（TIMI）风险评分是最方便和常用的系统，可以预测预后和血运重建的需求，但对于入院时的 AMI 患者不够充分。碎裂 QRS（fQRS）已被证明是预测冠心病患者预后的有价值的心电图（ECG）指标。此外，fQRS 被认为可以预测冠心病（CAD）患者发生不良结局和死亡的可能性增加，即使对于一些成功进行血运重建的 AMI 患者也是如此。那么如果将 fQRS 和 TIMI 风险评分结合起来会怎样呢？本研究旨在探讨 fQRS 与 TIMI 风险评分联合对 AMI 患者短期预后的价值。
