Heart care
High blood pressure often causes no symptoms, yet it raises the risk of heart attack, stroke, heart failure and kidney disease. We confirm readings, look for contributing causes, review medicines, and set a plan and target that fit you.
Overview
Blood pressure is the force of blood against artery walls, written as two numbers: systolic (when the heart beats) over diastolic (between beats). When it stays high, it strains the heart and damages blood vessels over time. Nearly half of U.S. adults have high blood pressure, and many do not know it.
Because a single office reading can be misleading, the 2025 American Heart Association and American College of Cardiology guideline recommends home monitoring with a validated device to help confirm the diagnosis and track treatment.
Who may benefit
Many people manage blood pressure with their primary care doctor. A cardiologist can help when control is difficult or when heart disease is also present.

Testing
| Test | Why it may be used |
|---|---|
| Blood and urine tests | Kidney function, potassium, blood sugar and cholesterol. The 2025 guideline recommends a urine albumin-to-creatinine test for people with high blood pressure. |
| ECG | Looks for signs of strain on the heart or rhythm problems. |
| Echocardiogram | Checks for thickening of the heart muscle and how well the heart pumps. |
| Renal vascular ultrasound | Sometimes used when narrowing of the kidney arteries is suspected as a cause. |
Treatment
Lower sodium intake, an eating pattern such as DASH, regular physical activity, limiting alcohol, reaching a healthier weight and good sleep all lower blood pressure for many people. They also make medicines work better.
Several classes of blood pressure medicine are available, and many people need more than one. The right choice depends on your other conditions, side effects and how your readings respond. Take medicines as prescribed and talk with your clinician before stopping or changing a dose.
Untreated sleep apnea can make blood pressure hard to control. If it is suspected, we coordinate testing with your primary care doctor or a sleep specialist. Other causes, such as kidney artery narrowing or hormone conditions, are considered when the pattern suggests them.
Visits are usually more frequent while treatment is being adjusted and less frequent once readings are steady.

Questions
Some people have higher readings in a medical setting, sometimes called white-coat hypertension. Others have the opposite pattern. Home readings help sort this out, which is why we ask you to bring them.
Current guidelines encourage most adults with high blood pressure to aim below 130/80 mm Hg, but your own target depends on your health, age and how you tolerate treatment. Your clinician will set it with you.
Normal readings on medicine usually mean the medicine is working. Talk with your clinician before making any change.
