Hypertension
Also known as: High blood pressure, HTN, elevated blood pressure
56%
Of Black adults have hypertension
Overview
Hypertension is a chronic condition in which the force of blood against artery walls is persistently elevated. Under the 2017 American Heart Association/American College of Cardiology guideline, hypertension is defined as blood pressure at or above 130/80 mmHg. Stage 1 is 130–139/80–89 mmHg; Stage 2 is 140/90 mmHg or higher. Often called the 'silent killer,' hypertension typically causes no symptoms until serious end-organ damage — heart attack, stroke, kidney failure, or heart failure — has occurred. Long-term control substantially reduces cardiovascular mortality and kidney disease progression.
How Hypertension affects Black patients
According to NHANES data analyzed by the CDC, approximately 56 percent of Black adults have hypertension — the highest rate of any racial group in the United States — and Black adults develop it at earlier ages, with more severe complications. The ALLHAT trial (the largest antihypertensive trial ever conducted, with a substantial Black cohort) and the AASK (African American Study of Kidney Disease and Hypertension) trial established that thiazide-type diuretics and calcium channel blockers (CCBs) produce superior blood pressure lowering in Black patients compared to ACE inhibitors used alone. The 2022 Flack et al. JACC consensus statement on hypertension in Black patients recommends combination therapy with a CCB plus thiazide as preferred first-line treatment. Chronic stress from racism — studied through the 'weathering' framework — contributes to earlier onset and severity.
Symptoms
- Usually none — hypertension is typically asymptomatic until complications arise
- Headache (especially morning occipital headache) in severe hypertension
- Shortness of breath or chest pain (suggest cardiac complication — seek emergency care)
- Nosebleeds (in severe or rapidly worsening hypertension)
- Vision changes or floaters (suggest hypertensive retinopathy)
- Sudden severe headache, confusion, or neurological symptoms (hypertensive emergency)
When to see a doctor
All adults should have blood pressure checked at least annually. Schedule an appointment when home readings consistently exceed 130/80 mmHg, even without symptoms. Start blood pressure monitoring earlier — in your 20s — if you are Black or have a family history of hypertension.
Seek emergency care immediately for blood pressure readings above 180/120 mmHg with symptoms (severe headache, chest pain, back pain, shortness of breath, neurological changes, or visual disturbances). This is a hypertensive emergency.
Screening
The USPSTF recommends blood pressure screening for all adults 18 and older. Adults 40 and older, or younger adults at elevated risk (including Black adults), should be screened annually. Home blood pressure monitoring with a validated upper-arm device is strongly encouraged for any patient diagnosed with or at risk for hypertension — it eliminates white-coat effect and provides more representative readings than office-only measurement.
Treatment overview
Lifestyle modification — reducing sodium intake to less than 1,500 mg/day for Black adults (per AHA), adopting the DASH (Dietary Approaches to Stop Hypertension) eating pattern, increasing aerobic activity, limiting alcohol, and achieving a healthy weight — is foundational for all patients. For medication, the 2022 JACC consensus for Black patients recommends a calcium channel blocker (amlodipine) or thiazide diuretic (chlorthalidone, hydrochlorothiazide) as preferred first-line agents, typically in combination at Stage 2. ACE inhibitors and ARBs are not preferred as monotherapy in Black patients but are essential when CKD or diabetes with proteinuria is present. Home blood pressure monitoring with a target below 130/80 mmHg is recommended for most adults.
Questions to ask your doctor
Bring this list to your next appointment.
- What is my blood pressure target, and how will we know we've reached it?
- Which medication is first-line for a Black patient like me — a CCB or thiazide diuretic?
- Should I be monitoring blood pressure at home? What device do you recommend?
- How much should I reduce sodium, and what practical changes help most?
- How often should you check my kidneys (eGFR, creatinine) given long-term hypertension?
- Am I eligible for a statin given my overall cardiovascular risk?
- What are the signs of a hypertensive emergency I should watch for at home?
