Various scoring systems have been developed to safely rule out the diagnosis of acute coronary syndrome. Furthermore, the efficacy of these scoring systems in predicting the risk of major adverse cardiac events (MACE) is debated. Our aim was to compare parameters such as Integrated Pulmonary Index (IPI) and End Tidal Carbon Dioxide (etCO2) measured in the emergency department with the HEART score in terms of its success in predicting the risk of major adverse cardiac events. Patients with atypical chest pain were registered for the study by the emergency room physician. The patients were investigated regarding gender, age, background characteristics, prognostic accuracy of etCO2, IPI, MACE, and HEART scores. As a result of the analysis, higher HEART Score and lower etCO2 values were determined in the MACE group compared to the group without MACE. ROC analysis was performed to determine the power of IPI, HEART Score, and etCO2 to predict MACE. The findings revealed that IPI significantly predicted MACE with an AUC value of 0.737. In our study, although the highest sensitivity values in determining the risk of 30-day MACE belonged to the HEART score, etCO2 and IPI might be other parameters that could be used to determine the risk of 30-day MACE.

二氧化碳图在确定非典型胸痛患者主要心脏不良事件风险中的应用

已经开发出各种评分系统来安全地排除急性冠状动脉综合征的诊断。此外，这些评分系统在预测主要不良心脏事件（MACE）风险方面的功效也存在争议。我们的目的是将急诊科测量的综合肺指数 (IPI) 和呼气末二氧化碳 (etCO2) 等参数与 HEART 评分进行比较，以了解其在预测主要不良心脏事件风险方面的成功程度。急诊室医生将患有非典型胸痛的患者登记参加该研究。对患者的性别、年龄、背景特征、etCO2、IPI、MACE 和 HEART 评分的预后准确性进行了调查。分析结果显示，与无 MACE 的组相比，MACE 组的 HEART 评分较高，etCO2 值较低。进行 ROC 分析以确定 IPI、HEART 评分和 etCO2 预测 MACE 的功效。研究结果显示，IPI 显着预测 MACE，AUC 值为 0.737。在我们的研究中，虽然确定 30 天 MACE 风险的最高敏感度值属于 HEART 评分，但 etCO2 和 IPI 可能是可用于确定 30 天 MACE 风险的其他参数。
