Dynamic changes and their clinical significance of plasma ET, CGRP and ANP in elderly patients with acute cerebral infarction / 临床神经病学杂志

ABSTRACT

Objective To determine the dynamic changes of plasma endothelin (ET), calcitonin gene related peptide (CGRP) and atial natriuretic peptide (ANP) in elderly patients with acute cerebral infarction and explore the pathological role of ET, CGRP and ANP in the development of acute cerebral infarction.Methods The concentrations of ET, CGRP and ANP in plasma were determined with radioimmunoassay in 78 elderly patients with acute cerebral infarction and 60 normal controls.Results (1)The levels of ET and ANP in patient group were significantly higher than those in control group ( P3 cm) and small area infarct group (1.5～3.0 cm) were significantly higher (all P
