BACKGROUND Hypertension (HTN) is a ubiquitous risk factor for numerous non-communicable diseases, including cardiovascular disease and stroke. There are currently no wholly effective pharmacological therapies for subjects with HTN. However, salt substitutes have emerged as a potential therapy for the treatment of HTN. The aim of the present study was to assess the effect of salt substitutes on reducing systolic blood pressure (SBP) and diastolic BP (DBP), following a meta-analysis of randomized controlled trials. METHODS Studies were found via systematic searches of the Pubmed/Medline, Scopus, Ovid, Google Scholar and Cochrane library. Ten studies, comprised of 11 trials and 1119 participants, were included in the meta-analysis. RESULTS Pooled weighted mean differences showed significant reductions of SBP (WMD - 8.87 mmHg; 95% CI - 11.19, - 6.55, p < 0.001) and DBP (WMD - 4.04 mmHg; 95% CI - 5.70, - 2.39) with no statistically significant heterogeneity between the 11 included comparisons of SBPs and DBPs. The stratified analysis of trials based on the mean age of participants showed a significant reduction in the mean difference of SBP in both adults (< 65 years old) and elderly (≥65 years old). However, the DBP-lowering effect of salt substitutes was only observed in adult patients (WMD - 4.22 mmHg; 95% CI - 7.85, - 0.58), but not in the elderly subjects. CONCLUSIONS These findings suggest that salt-substitution strategies could be used for lowering SBP and DBP in patients with stage 2 HTN; providing a nutritional platform for the treatment, amelioration, and prevention of HTN.

盐替代品在2期高血压中的降压作用:系统评价和荟萃分析。

背景技术高血压(HTN)是许多非传染性疾病普遍存在的危险因素,包括心血管疾病和中风。目前尚无针对HTN受试者的完全有效的药理疗法。但是,盐替代品已成为治疗HTN的潜在疗法。在随机对照试验的荟萃分析之后,本研究的目的是评估盐替代品对降低收缩压(SBP)和舒张压(DBP)的作用。方法通过对Pubmed / Medline,Scopus,Ovid,Google Scholar和Cochrane库的系统搜索来发现研究。荟萃分析包括10项研究,包括11个试验和1119名参与者。结果汇总加权平均差异显示SBP显着降低(WMD-8.87 mmHg; 95%CI-11.19,-6.55,p <0.001)和DBP(WMD-4.04 mmHg; 95%CI-5.70,-2.39),在11个SBP和DBP的比较之间没有统计学上的显着异质性。根据参与者平均年龄进行的分层试验分析显示,成年人(<65岁)和老年人(≥65岁)的SBP平均差异显着降低。然而,仅在成年患者(WMD-4.22 mmHg; 95%CI-7.85,-0.58)中观察到盐替代品降低DBP的作用,而在老年患者中则没有。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。39)在SBP和DBP的比较中没有11个统计上的显着异质性。根据参与者平均年龄进行的分层试验分析显示,成年人(<65岁)和老年人(≥65岁)的SBP平均差异显着降低。然而,仅在成年患者(WMD-4.22 mmHg; 95%CI-7.85,-0.58)中观察到盐替代品降低DBP的作用,而在老年患者中则没有。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。39)在SBP和DBP的比较中没有11个统计上的显着异质性。根据参与者平均年龄进行的分层试验分析显示,成年人(<65岁)和老年人(≥65岁)的SBP平均差异显着降低。然而,仅在成年患者(WMD-4.22 mmHg; 95%CI-7.85,-0.58)中观察到盐替代品降低DBP的作用,而在老年患者中则没有。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。根据参与者平均年龄进行的分层试验分析显示,成年人(<65岁)和老年人(≥65岁)的SBP平均差异显着降低。然而,仅在成年患者(WMD-4.22 mmHg; 95%CI-7.85,-0.58)中观察到盐替代品降低DBP的作用,而在老年患者中则没有。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。根据参与者平均年龄进行的分层试验分析显示,成年人(<65岁)和老年人(≥65岁)的SBP平均差异显着降低。然而,仅在成年患者(WMD-4.22 mmHg; 95%CI-7.85,-0.58)中观察到盐替代品降低DBP的作用,而在老年患者中则没有。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。结论这些发现表明,盐替代策略可用于降低2期HTN患者的SBP和DBP。为HTN的治疗,改善和预防提供营养平台。
