概括
N-终端亲B型尿酸 (NT-proBNP) 水平预测心房动和中风风险. 在高NT-proBNP个体中,可植入循环记录器查减少了中风,这表明查的有效性.
科学领域:
- 心脏病学
- 生物标志物
- 预防医学
背景情况:
- N-终端亲B型尿素 (NT-proBNP) 是已知的心房动 (AF) 和中风的预测因子.
- 在指导AF查策略方面,NT-proBNP的有效性尚不清楚.
研究的目的:
- 评估NT-proBNP作为AF查疗效的标志物.
- 在查背景下评估它在中风预防中的作用.
主要方法:
- 在LOOP研究中对5819名先前未患过脑筋梗塞的患者 (≥70岁) 进行了后期分析.
- 参与者被随机分为植入式循环记录器 (ILR) 查或常规护理.
- 在基线测量NT-proBNP水平以分层风险和分析查结果.
主要成果:
- 较高的NT-proBNP水平与增加的AF诊断风险和较高的中风,心血管死亡和全因死亡率有关.
- 在高NT-proBNP的参与者中,ILR查显著减少了中风/全身血栓塞 (SE) 和中风/SE/心血管死亡,但在较低水平的参与者中没有.
- 在NT-proBNP亚组进行ILR查时,没有观察到任何原因死亡的显著减少.
结论:
- 在高风险的老年人中,ILR对AF的查显示了中风风险的降低,主要是在NT-proBNP水平升高的个体中.
- 这些发现表明NT-proBNP可能有助于识别AF查中受益最大的个体.
- 在临床实施之前,需要进一步的研究来证实这些产生假设的结果.

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...

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
