Study was a pilot study and the investigators received funding to initiate the main study

Pediatric hypertension is increasingly common and is a precursor for adult cardiovascular and renal disease. But even during childhood, hypertension is associated with significant morbidity, including cognitive impairment and organ damage. However, the cause of pediatric hypertension, the response to treatment, and the mechanisms behind organ damage are incompletely understood. Due to these limitations, there are no first-line medications, and treatment is often inadequate. An improved comprehension of the course of pediatric hypertension could enhance clinical care. The goal of this proposal is to create a registry of patients with hypertension to better enable research into this important disease. This patient registry will enhance the investigators ability to quickly collect and analyze data for research studies.

The investigators will include all subjects evaluated at the Brenner Children's Hospital Pediatric Nephrology clinic since January 1st, 2013 with a diagnosis of high blood pressure confirmed with three separate blood pressure measurements >=90th percentile for age, sex, and height, or >120/80 mmHg. The investigators will exclude patients whose initial evaluation occurred on or after their 18th birthday.

Inclusion Criteria:

- Patients at one of the following : Wake Forest Baptist Health Brenner Children's Hospital Pediatric Nephrology clinic Emory University Pediatric Nephrology

• Diagnosis after January 2013
• >90th percentile for age, sex, height, or >120/80.

Exclusion Criteria:

- Patients whose initial evaluation occurred on or after their 18th birthday.

Subjects that are patients in the Brenner Children's Hospital Pediatric Nephrology Clinic or Emory University Pediatric Nephrology with a confirmed diagnosis of high blood pressure.
