Aldosterone Disorder

The goal of the REFOCUS-HTN US-WEST program is to gain a better understanding of the role of a hormone called aldosterone in the development of hypertension. The SCALED sub-study is an observational cohort study that will enroll from REFOCUS-HTN cohort for prospective data collection.

This will be a crossover controlled trial designed to recruit 40 participants, who will be divided into two groups of 20 subjects each. The participants will be randomly assigned to either Group A or Group B. Group A will receive the sleep electric blanket intervention for a period of 7 days, while Group B will serve as the control group without any additional intervention. After the intervention period, there will be a washout period of 7 days to ensure that any effects of the intervention have subsided before the crossover. Following the washout period, the groups will switch roles: Group B will then receive the sleep electric blanket intervention, and Group A will become the control group. This second phase will also last for 7 days, preceded and followed by the same assessment procedures as the initial phase. This design will allow for a comparison of the intervention's effects against a control period within the same group of participants, enhancing the study's internal validity.
