Even with several prior training revealing a connection ranging from blood pressure level and you will this new urinary Na + /K + proportion there are limitations as noticed

At present there is conflicting evidence regarding the potential blood pressure lowering effects of a reduction in urinary Na + /K + excretion. The TAIM randomized control trial in hypertensive participants on a pharmacological intervention reported no significant difference in DBP between the control diet group and a low Na + /high K + diet group during a six month period . A multicenter study by Suppa et al. conducted in hypertensive participants reported a significant reduction in SBP following 4 weeks of modified low sodium high potassium salt intake compared to participants receiving a normal salt intake , yet all participants were receiving a beta blocker, which is not standard first line treatment for hypertension . In addition, a cross-sectional study, the Dallas heart study, which reported an increase in SBP for an increase in the urinary Na + /K + ratio is limited by the modest correlation the use of single morning urine sample . The PURE study reported a strong linear association between estimated Na + /K + ratio and SBP, that was maintained after covariate adjustment, with the greatest SBP observed with the highest estimated K + and lowest estimated K + excretion . Although we observed that a daily K + excretion of <1 g/day is associated with elevated SBP we observed no association between the urinary Na + /K + excretion ratio and SBP at screening or following DASH-dietary intervention in SS or SR participants. In conjunction with the study by Zanetti et al. , our data suggest high Na + and low K + excretion may increase the likelihood of having increased SBP. However, the lack of association between urinary Na + /K + ratio and SBP in our data do not support a urinary Na + /K + molar excretion ratio of 1:1 as a mechanism to lower blood pressure [16, 17].

The modern data has numerous strengths: (1) The fresh new Dash -Sodium demonstration try a carefully managed serving analysis and compliance is constantly tracked, (2) The new crossover framework to possess Na + intervention anticipate https://datingranking.net/pl/fcn-chat-recenzja/ participant’s so you’re able to act as her manage and you can diminished inter-person variability, (3) 24-h ambulatory hypertension recordings were drawn, (4) lack of the confounding effects of antihypertensive mediations, and you will (5) 24-h pee sample collection. The major maximum of one’s expose investigation ’s the relatively more compact sample dimensions which can features reduced the statistical capacity to find modest ramifications of urinary Na + , K + , and you may Na + :K + ratio toward SBP. As we failed to observe an instability when you look at the baseline attributes, residual confounding inside our studies can be done.

Subsequent, the latest INTERSALT research, and this documented an optimistic connection between your urinary Na + /K + ratio and you will blood pressure level advertised a loss in analytical requirement for new relationship into the 44 of the 52 locations immediately following changes having covariates including years, gender and you can Body mass index [thirty two, 33]

In conclusion the current data of your own Dashboard–Sodium Trial demonstrates fat loss K + supplementation isn’t associated with the all the way down SBP which the latest decreases into the SBP observed pursuing the Dashboard diet intervention happened independently off a great decrease in the fresh new urinary Na + /K + removal proportion aside from the fresh new sodium sensitivity regarding blood circulation pressure. All of our research don’t contain the facilities away from a-1:step one molar excretion proportion out of Na + /K + given that blood pressure lowering method in United states Ebony and you will non-African People in the us and hold the DRI testimonial never to suggest each day K + intake direction. Considering the limitations of your own newest analysis as well as the ongoing debate regarding the character away from weightloss K + towards blood pressure level upcoming very carefully controlled research is required to clarify the potential impression off dietary K + and you may urinary Na + /K + excretion proportion for the hypertension in hypertensive and you will normotensive SS and SR people.
