概括
在非ST升高心肌梗塞 (NSTEMI) 后的延迟冠状动脉造影与显著更高的重大心血管不良事件 (MACE) 和死亡率有关. 早期干预 (<24小时) 似乎可以改善NSTEMI患者的长期结果.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 急性冠状动脉综合征是什么
背景情况:
- 关于非ST升高心肌梗塞 (NSTEMI) 中冠状动脉血管学最佳时间的证据有限.
- 目前的指导方针缺乏针对NSTEMI患者的早期或延迟干预的具体建议.
- 对NSTEMI的风险分层要求对干预时间的影响进一步明确.
研究的目的:
- 为了评估NSTEMI患者的长期主要不良心血管事件 (MACE).
- 为了比较早期 (<24小时) 与延迟 (>24小时) 冠状动脉血管学的结果.
- 评估干预时间对所有原因死亡率和累积MACE的影响.
主要方法:
- 从2017年至2018年分析了355名NSTEMI患者的队列.
- 考克斯的比例危险模型被用来评估MACE和死亡率.
- 根据GRACE评分,人口统计,生物标志物和并发症进行了调整.
主要成果:
- 延迟血管造影 (中位数为45.4小时) 与早期血管造影 (中位数为13.3小时) 相比,与更高的MACE率有关.
- 在多变量调整后,延迟干预增加了MACE (HR=1.79) 和所有原因死亡率 (HR=2.76).
- 累积MACE发病率在延迟组中也更高 (IRR=1.54).
结论:
- 在NSTEMI患者中,延迟冠状动脉造影与更糟糕的长期心血管结果有关.
- 需要进一步调查,包括随机对照试验.
- 应考虑在所有NSTEMI风险组进行早期侵入性干预.

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...
01:30Acute Coronary Syndrome I: Introduction
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...
01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
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...
01:30Acute Coronary Syndrome III: Diagnostic Studies
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...
01:28Acute Coronary Syndrome IV: Interprofessional Care
IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
01:29Angina III: Clinical Manifestations and Assessment
Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...
