目前血管钙化(vascular calcification,VC)被认为是慢性肾脏病(chronic kidney disease,CKD)患者常见的并发症,血管钙化的程度是强有力的心血管病死率的预测因素[1]。血管钙化患者可出现血管顺应性降低、动脉舒张能力减弱、心脏后负荷增加、难以控制的高血压及脏器缺血等。因此,早期发现及预防CKD患者血管钙化,对于预防心血管事件的发生具有重要意义。 At present, vascular calcification (VC) is considered as a common complication in patients with chronic kidney disease (CKD). The degree of vascular calcification is a predictor of potent cardiovascular mortality [1]. Vascular calcification may occur in patients with decreased vascular compliance, reduced arterial diastolic capacity, increased cardiac afterload, difficult to control the hypertension and organ ischemia. Therefore, the early detection and prevention of vascular calcification in patients with CKD, for the prevention of cardiovascular events is of great significance.
