在正常和病理生理条件下,β肾上腺素能受体通过其相应的信号分子对心脏及血管的功能均有重要的调节作用,心血管疾病患者外周血淋巴细胞膜β受体的变化能够很好地反映心脏β受体的改变,因此外周血淋巴细胞β受体密度的变化可以作为心脏β受体的一个监测指标。 Under normal and pathophysiological conditions, β-adrenergic receptors play an important regulatory role on the function of the heart and blood vessels through their corresponding signaling molecules. The changes of β receptors in the peripheral blood lymphocytes of patients with cardiovascular diseases can be well regulated Reflects the changes of cardiac β receptor, so the changes of peripheral blood lymphocyte β receptor density can be used as a cardiac β receptor monitoring indicators.
