Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with established hypertension within Kaiser Permanente Northern California, with 6+ months of continuous health coverage and meeting recent screening criteria for aldosterone dysregulation.

Probably not a fit

Individuals without aldosterone-related hypertension or without eligibility criteria may not see direct benefits from this observational work.

What this trial studies

REFOCUS-HTN US-WEST is an observational program combining retrospective data and a prospective sub-study called SCALED to describe aldosterone dysregulation in hypertension. The SCALED sub-study enrolls about 500 adults from the REFOCUS-HTN cohort and collects primary data at baseline to explore the role of aldosterone in resistant and stage 2 hypertension. The project aligns with updated guidelines that emphasize screening for primary aldosteronism and aims to inform individualized and population-level hypertension management. Data are drawn from electronic health records and new clinical assessments to characterize prevalence, clinical features, and potential treatment implications. The lead sponsor is Kaiser Permanente with collaboration from AstraZeneca, focusing on the Northern California region.

Why it matters

Potential benefit: If successful, the study could improve identification of aldosterone-related hypertension and inform more targeted, individualized management strategies.

How similar studies have gone: Previous observational work in this area has provided foundational insights but this program offers prospective data collection to better describe aldosterone dysregulation in a real-world setting.

Inclusion Criteria:

The SCALED Cohort will be identified from the REFOCUS-HTN Cohort which includes men and women ≥ 18 years of age with established hypertension in the KPNC EHR from January 2012 through March 31, 2029. Established hypertension will be defined as one of the following:

* ≥1 outpatient, non-emergency department diagnosis of hypertension;
* ≥2 consecutive outpatient measures of systolic blood pressure ≥130 mmHg at least 90 days apart;
* ≥2 consecutive outpatient measures of diastolic blood pressure ≥80 mmHg at least 90 days apart.

Additional Eligibility Criteria for SCALED:

* Hypertension diagnosis within the past 18 months prior to screening.
* At least 6 months of continuous health plan coverage prior to initial visit.

Exclusion Criteria:

* Diagnosed cause of secondary hypertension from drug or alcohol induced, or renovascular hypertension;
* Bariatric surgery or GLP1 prescription in the last 12 months;
* Exposure to an aldosterone synthase inhibitor or a mineralocorticoid receptor antagonist in the last 12 weeks;
* Last known estimated glomerular filtration rate \< 45 mL/min/1.73m2 (according to the CKD-EPI equation) at the time of screening;
* Kidney transplant;
* Currently receiving dialysis;
* Current enrollment in any cardiovascular or blood pressure interventional trial.
