| 英文摘要: |
| Interaction between the heart and kidney in the field of hemodynamics and regulation of neurohumoral contributes to
maintain circulatory homeostasis under normal conditions. Nevertheless, the normal regulatory mechanisms are inappropriate at the
beginning of congestive heart failure. Data from surveys showed that in-patients for acute decompensated congestive heart failure (CHF)
have some degree of renal insufficiency. The renal nerves play a pivotal role in the renal dysfunction that occurs in CHF. The activation
of renal sympathetic efferent nerves caused by congestive heart failure can not only lead to rennin release, sodium and water retention,,
reduced renal blood blow, but also elevate peripheral vascular resistance, increase left ventricular remodeling and resulted in its
dysfunction. Evidence from the animal models of heart failure demonstrates that surgical renal denervation has been proved to improve
renal and ventricular function, expecially for blood pressure lowering and improvement of left ventricular function. However, the invasive
nature of this approach and its associated complication may limit its applicability. Recently, a catheter-based renal sympathetic
denervation has been shown to interrupt both efferent and afferent renal nerves, and widely used in the treatment of hypertension and
heart failure. In this review, we update the activation of efferent and afferent renal nerve activation in heart failure, together with the
comprehensive review, of relevant experimental models and clinical trials. These results suggest that a catheter-based renal denervation
may be a novel target treatment for CHF patients. |
