Study TitleAmino Acd Metabolites of Dietary Salt Effects on Blood Pressure in Human Urine from 20 Participants of the DASH2 Clinical Trial (part II)
Study SummaryThe objective of the study is to identify changes of urinary metabolite profiles associated with different responses to blood pressure to salt. Subjects are derived from The Dietary approaches to stop hypertension (DASH) diet, Sodium Intake and Blood Pressure Trial (Sacks FM et al PMID: 11136953,N Engl J Med. 2001).We choose two groups subjects who meet the following conditions(the two groups are separately named A and B). We chose subjects on the Control diet .These subjects meet the blood pressure criteria described below:Group A subjects conditions: 1) On Control diet. 2) Normotensive subjects: systolic blood pressure from the low sodium visit is less than 140 and the diastolic blood pressure from low sodium visit is less than 90; 3) For group A: Either the systolic blood pressure from the high sodium visit was greater than 10 mmHg higher than the systolic blood pressure from the low sodium visit, or the diastolic blood pressure from the high sodium visit was greater than 10 mmHg higher than the diastolic blood pressure from the low sodium visit; 3) For group B: The systolic blood pressure from the high sodium visit is within 5 mmHg (i.e. +/- 5) from the systolic blood pressure from the low sodium visit, and the diastolic blood pressure from the high sodium visit is within 5 mmHg from the diastolic blood pressure from the low sodium visit. Use gas chromatography/mass spectrometry (GC/MS) analysis, and liquid chromatography/mass spectrometry (LC/MS)analysis to find the differences of metabolic profiles between the high sodium level and the low sodium level, and compare the metabolic profiles of A with the metabolic profiles of B at the low and high sodium level. Note, this was used as a pilot, the rest of the samples are in another uploaded study.
