Official title
Prospective Early Patient Experience Initiative (IMPACT-HTN)
Overview
An estimated 120 million people have high blood pressure (hypertension) in the US, of which approximately 10% have resistant hypertension. This study aims to enroll patients who continue to have hypertension while being treated with at least two medications. The study will follow patients for approximately 3 months and collect real-world information on changes in their health to identify an ideal patient profile that would benefit from 4th-line antihypertensive therapies, including, but not limited to, FDA-approved aprocitentan, renal denervation, mineralocorticoid receptor antagonists, etc.
Detailed description
To date, there is little multi center data on the management of patients in HTN centers. Elevated blood pressure is the leading global risk factor for death and nonfatal cardiovascular events, primarily strokes, myocardial infarctions, heart failure leading to hospitalization, and end-stage renal disease. After a one-year pilot with two sites, this study plans to expand to additional sites to build a national registry for resistant hypertension research.
This collaborative, prospective study will evaluate the effectiveness and safety of resistant hypertension management, including the use of novel drugs with the aim of defining an ideal patient profile that would benefit from various 4th-line antihypertensive therapies, including, but not limited to, aprocitentan, renal denervation, mineralocorticoid receptor antagonists, etc.
Primary outcome measures
- Difference between exposure groups in change from baseline to Month 3 mean systolic blood pressure [Time frame: 90 days]
Secondary outcome measures (2)
- Change from baseline to Month 3 in urine albumin-to-creatinine ratio (UACR) in the overall cohort and between exposure groups [Time frame: 90 days]
- Interaction between exposure group and baseline albuminuria category on UACR change from baseline to Month 3 [Time frame: 90 days]
Eligibility criteria

- Mean Sitting Systolic Blood Pressure (SiSBP) greater or equal to 130 mmHg
Exclusion criteria
- Confirmed severe hypertension (grade 3) defined as SiSBP greater than or equal to 180 mmHg and/or Sitting Diastolic Blood Pressure (SiDBP) greater than or equal to 110 mmHg
