Salt-Sensitivity and Immunity Cell Activation

Blood pressure data from the monitors will be downloaded and the average of the systolic blood pressure of the day of salt loading, from 12 noon (end of the saline infusion) until 10 pm will be used as the BP for the salt-loading period of study. The average of the systolic blood pressure of the day of salt depletion, from 12 noon (second dose of furosemide) until 10 pm will be used as the BP for the salt-depleted period of study. A fall in systolic BP ≥10 mm Hg from the salt-loading to the salt-depletion periods will be used to classify a subject as salt sensitive.
