概括
在症状出现后4. 5小时内治疗中国患者的急性缺血性中风 (AIS) 的效果与阿尔特普拉斯无差别. 这两种治疗方法在90天后表现出相似的安全性和功能性结果.
科学领域:
- 神经学
- 心血管医学
- 药理学
背景情况:
- 在急性缺血性中风 (AIS) 治疗中,tenecteplase是一种生物工程 alteplase 变体,可提高纤维素特异性和延长半衰期.
- 在中国的AIS患者中,有有限的证据证明了tenecteplase (0. 25 mg/ kg) 的有效性和安全性.
研究的目的:
- 在AIS患者接受症状发作后4. 5小时内治疗时,以确定与alteplase相比,tenecteplase的非劣势性.
- 在中国人群中评估甲与甲的功能结果和安全性.
主要方法:
- 一个多中心的,随机的,主控的,开放的,盲目的终点非劣质性试验 (原始研究) 涉及中国的1465名AIS患者.
- 患者在症状发作后4. 5小时内被随机分为1:1接受静脉注射的丁氏甲基 (0. 25 mg/ kg) 或高氏甲基 (0. 9 mg/ kg).
- 主要结论是患者在90天内达到0或1的修改Rankin尺度 (mRS) 得分的比例,与0. 937的风险比率差额相比,评估了非劣势性.
主要成果:
- 72. 7% 的患者获得了0- 1 的mRS评分,而70. 3% 的mRS评分 (风险比率[RR],1. 03;95% CI,0. 97-1. 09).
- 症状性脑内出血的发生率相似: 甲和高甲组均为1. 2% (RR,1. 01; 95% CI,0. 37-2. 70).
- 90天所有原因的死亡率为tenecteplase的4. 6%和alteplase的5. 8% (RR,0. 80;95% CI,0. 51至1. 23).
结论:
- 在接受4. 5小时内治疗的中国AIS患者中,tenecteplase的功能效果不低于alteplase.
- 甲的安全性与甲相似,包括症状性脑内出血率和90天死亡率.
- 在特定的时间窗口内接受治疗的AIS患者中,特内克是一种适合于阿尔特的替代品.

Acute Coronary Syndrome III: Diagnostic Studies
495
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...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
