摘要

应用冠脉结扎技术和生物测定法

观察急性心力衰竭（HF）大鼠心房肌提取物（AE）中心房钠尿因子（ANF）活性的改变.结果提示

急性HF时心房ANF含量和（或）活性的改变与慢性HF时有差别

心房肌肥大可能通过增加ANF的合成、贮存和释放过程而起到重要的代偿作用

Abstract

The renal and hemodynamin responses of normal assay rats to atrial extracts (AE) of the rats with acute heart failure (HF) induced by coronary ligation and of the sham-operated control rats were assessed four days after the operation. The hypotensive action was similar in the two groups of AE

but the AE of HF rats showed stronger diuretic (1077±136 vs 818±116μ1/10 min

P=0.05) and natriuretic effects (161±25vs 120±17μmol/10 min

P< 0.025) than control AE. Inversely

the negatively chronotropic effect of AE from HF rats was weaker compaired with that of control AE (P<0.05). A significant increase of atrial weight in HF rats was observed (146±11vs 93±5mg

P<0.001). These results suggest 1) in the acute phase of HF

changes of the total content and/or bioactivity of atrial natriuretic factor (ANF) in atria is different from that observed ia chronic HF

and 2) hypertrophy of atrial myocyte may play an important compensatory role in the early phase of HF through the enhancement of synthesis

storage

and release of ANF
