Elevated Blood Pressure
Conditions
Brief summary
This will be a prospective observational study. The population would be pediatric patients 6 years to \<19 years of age who were referred for elevated blood pressure to investigate if home blood pressure (HBP) can determine blood pressure phenotype (normotensive, hypertensive, masked hypertension, white coat hypertension) as accurately as ambulatory blood pressure monitor (ABPM) in childhood and adolescence.

Eligibility
Inclusion criteria
1. Age 6 years to \<19 years old; 2. Elevated blood pressure defined as 15% lower than the 95%ile BP based on clinical practice guidelines(CPG) but less than stage II hypertension based on CPG; 3. Tolerate ABPM 24 hours; 4. Tolerate HBP; and 5. Can have diabetes mellitus, obstructive sleep apnea, and attention deficit hyperactivity disorder managed by medication. 6. On stable doses of medications known to affect BP such as: 1. Corticosteroids 2. Calcineurin inhibitors 3. Oral decongestants; 7. Clinically stable
Exclusion criteria
1. On antihypertension medications or treated in the last 6 months; 2. Pregnant; 3. Structural heart disease such as: 1. Obstructive valvular disease 2. Coarctation of the aorta 3. Cardiomyopathy; 4. Other secondary causes such as: 1. Renal artery stenosis 2. Neurological condition with dysautonomia; 5. Recent initiation of medications known to affect BP such as: 1. Corticosteroids 2. Calcineurin inhibitors 3. Oral decongestants;
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Determine blood pressure phenotype | 6-12 months after enrollment | The primary objective of this study is to investigate if home blood pressure (HBP) can determine blood pressure phenotype (normotensive, hypertensive, masked hypertension, white coat hypertension) as accurately as ambulatory blood pressure monitor (ABPM) in childhood and adolescence. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| HBP correlation with end organ damage | 6-12 months after enrollment | Our secondary objective is to determine if HBP correlates with end organ damage (i.e. elevated left ventricular mass, increased arterial stiffness, and decreased left ventricular strain) better than office BP. Our central hypothesis is that home blood pressure will accurately identify blood pressure phenotype and will correlate with end organ damage. |
