Key Takeaways

  1. Normal blood pressure is defined as below 120 mmHg systolic and below 80 mmHg diastolic, per 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines.
  2. High blood pressure is often called the "silent killer" because 90% of people with persistent elevated readings experience no obvious symptoms, even as it damages organs over time.
  3. The ACC/AHA classifies hypertension as any consistent reading above 130/80 mmHg, which means 46% of U.S. adults meet the clinical criteria for high blood pressure.
  4. Lifestyle modifications can lower systolic blood pressure by 5-8 mmHg, and in some cases of mild elevated pressure, they can eliminate the need for medication entirely.
  5. Consistent at-home monitoring with a validated upper-arm cuff is more accurate than occasional office readings for diagnosing and managing long-term high blood pressure.
  6. Uncontrolled high blood pressure increases your risk of heart attack by 2x, stroke by 4x, and chronic kidney disease by 3x compared to people with stable, normal readings.
