红细胞分布宽度是反映周围红细胞体积大小变异性的参数。近年研究发现,红细胞分布宽度增高与急、慢性心力衰竭的严重程度与预后有关。这可为临床提供心力衰竭患者的危险度分层及判断预后的重要信息。但其根本机制尚待进一步探讨。
The distribution width of red blood cells is a parameter that reflects the variability of the size of the surrounding red blood cells. In recent years, studies have found that increased width of red blood cell distribution and acute and chronic heart failure severity and prognosis. This may provide clinically important information on the risk stratification and prognosis of patients with heart failure. However, its fundamental mechanism remains to be further explored.
