B-type natriuretic peptide (BNP) and its N-terminal fragment (NT-proBNP) are released from ventricular cardiomyocytes in response to an increase in ventricular wall stress and to myocardial ischemia. Both BNP and NT-proBNP have proven to be reliable diagnostic and prognostic biomarkers in patients with heart failure. Recently, the diagnostic roles of BNP and NT-proBNP in patients with coronary artery disease (CAD) have been investigated. For patients with acute coronary syndromes, data have been derived from a great number of studies, whereas in patients with stable CAD, only a limited amount of recent data is available; although limited, these data show that elevations in BNP and NT-proBNP levels are associated with the extent of CAD, thus providing prognostic information for an unfavourable clinical outcome. However, clinical and therapeutic implications are indistinct and need to be elucidated in further studies.
B型利钠肽(BNP)及其N端片段(NT-proBNP)是心室心肌细胞在心室壁压力增加和心肌缺血时释放的。BNP和NT-proBNP已被证明是心力衰竭患者可靠的诊断和预后生物标志物。最近,BNP和NT-proBNP在冠状动脉疾病(CAD)患者中的诊断作用已得到研究。对于急性冠状动脉综合征患者,已有大量研究数据,而对于稳定型CAD患者,近期仅有有限的数据;尽管数据有限,但这些数据表明BNP和NT-proBNP水平升高与CAD的严重程度相关,从而为不良临床结局提供预后信息。然而,临床和治疗意义尚不清楚,需要进一步研究阐明。
