概括
假阳性ST段升高心肌梗塞 (STEMI) 警报可以取消,但很少有急性冠状动脉封闭 (ACO) 病例被遗漏. 这些遗漏的ACO患者心血管风险和死亡率较高.
科学领域:
- 心脏病学 心脏病学
- 紧急医疗 紧急医疗
- 医疗信息学 医疗信息学
背景情况:
- ST段升高心肌梗塞 (STEMI) 网络的目标是快速反,但面临着假阳性激活的挑战.
- 远程评估允许取消STEMI警报以优化导管实验室资源.
- 这种策略有可能错过急性冠状动脉封闭 (ACO) 病例,需要紧急干预.
研究的目的:
- 在取消的STEMI警报中评估错过的急性冠状动脉封闭 (ACO) 的发生率和特征.
- 为了确定最初假阳性STEMI警报的患者中ACO的预测因子和结果.
主要方法:
- 通过ODISEA数字平台取消的STEMI警报的前性,单中心研究 (2022年1月 - 2024年12月).
- 冠状动脉血管学将患者分为ACO (TIMI 0-1流量) 或没有闭塞的组.
- 基线特征,心电图发现和住院死亡率的比较.
主要成果:
- 在2259次STEMI激活中,有665次 (29.4%) 被取消;28次 (4.2%) 有ACO.
- 在ACO患者中,高血压,糖尿病和先前冠状动脉旁路移植的发病率更高.
- 在错过的ACO病例中,微妙或非经典的心电图发现很常见;住院死亡率更高 (10.7%vs7.7%).
结论:
- 错过的急性冠状动脉封闭 (ACO) 在取消的STEMI警报中不常见,但与显著的心血管风险因素相关.
- 错过ACO的患者经常出现不典型的心电图 (ECG) 发现.
- 这些发现强调需要仔细评估取消的STEMI警报,以避免不良结果.

1.1K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
