The article presents changeability of renal resistive index (RRI) in various cardiovascular diseases and considers the usefulness of the marker and interpretational difficulties of the index. The values of RRI are not specific to an individual disease, but in a selected group of patients, it seems to be a perfect marker of cardiovasculorenal changes and a predictor of rapid loss of a renal function. The RRI usually does not reflect the vascular resistance, but is dependent on total and local vascular bed compliance changing with age, in the course of consecutive diseases and the influence of drugs. Under specific conditions, RRI appears to be a good marker of vascular damage. This review summarizes current concepts in RRI interpretation against the cardiovascular pathologies, focusing on the vascular damage association with regard to the complex nature of RRI value variability.
本文介绍了肾阻力指数(RRI)在各种心血管疾病中的变化情况,并探讨了该指标的实用性及解读难点。RRI值并非某一种疾病所特有,但在特定患者群体中,它似乎是心血管肾脏变化的理想指标,也是肾功能快速丧失的预测指标。RRI通常并不反映血管阻力,而是取决于随年龄变化、在一系列疾病过程中以及药物影响下的总血管床和局部血管床顺应性。在特定条件下,RRI似乎是血管损伤的良好指标。本综述总结了针对心血管疾病解读RRI的当前概念,重点关注RRI值变异性的复杂性质与血管损伤的关联。
