H型高血压患者血压动态指标与盐摄入量的相关性分析

Correlations between blood pressure dynamic indexes and salt intake in patients with H-type hypertension

摘要

摘要:
目的探讨H型高血压患者血压动态指标与盐摄入量的相关性。
方法选取2018年3月—2020年12月确诊的H型高血压患者406例。采用不同浓度的生理盐水测定患者的盐阈值，并利用尿钠检测进行验证。采用动态血压监测观察患者的血压动态指标变化情况; 采用Spearman相关性分析检验患者血压动态指标与盐摄入量的相关性。
结果不同盐阈值H型高血压患者的口味分布比较，差异具有统计学意义(P < 0.05)。H型高血压患者的平均收缩压、舒张压与盐阈值的相关性系数分别为0.334、0.278; 平均收缩压、平均舒张压的血压变异性与盐阈值的相关性系数分别为0.134、0.079; 血压昼夜节律与患者盐阈值的相关性系数为0.087。
结论 H型高血压患者血压动态指标与盐摄入量存在一定程度的相关性，且盐摄入量对血压动态指标表现为正向影响。

Abstract:
Objective To investigate the correlations between blood pressure dynamic indexes and salt intake in patients with H-type hypertension.
Methods A total of 406 patients with H-type hypertension diagnosed from March 2018 to December 2020 were selected. The salt threshold of the patients was measured with different concentrations of normal saline and verified by urine sodium detection. Ambulatory blood pressure monitoring was used to observe the changes of blood pressure dynamic indexes. Spearman correlation test was used to analyze the correlations between blood pressure dynamic indexes and salt intake.
Results The taste distribution of H-type hypertension patients with different salt threshold showed significant difference (P < 0.05). The correlation coefficients of mean systolic blood pressure, diastolic blood pressure and salt threshold in patients with H-type hypertension were 0.334 and 0.278, respectively; the correlation coefficients of mean systolic blood pressure and mean diastolic blood pressure with salt threshold were 0.134 and 0.079, respectively; the correlation coefficient between circadian rhythm of blood pressure and salt threshold of patients was 0.087.
Conclusion There is a certain degree of correlation between blood pressure dynamic indexes and salt intake in patients with H-type hypertension, and salt intake has a positive effect on blood pressure dynamic indexes.
