New definition of hypertension
The American Heart Association (AHA) and the American College of Cardiology (ACC) have recently updated the definition of hypertension, which is now based on an average of multiple blood pressure readings taken over time, rather than a single reading. Here are the new guidelines:
New Definition of Hypertension (2017)
- Normal blood pressure: Less than 120/80 mmHg
- Elevated blood pressure: 120-129/80 mmHg
- Stage 1 hypertension: 130-139/80-89 mmHg
- Stage 2 hypertension: 140 or higher/90 or higher mmHg
Key Changes:
- Average of multiple readings: The new definition takes into account the average of multiple blood pressure readings, rather than a single reading. This is because blood pressure can fluctuate throughout the day, and a single reading may not accurately reflect a person's overall blood pressure.
- Elevated blood pressure category: The new definition introduces an "elevated blood pressure" category, which is defined as 120-129/80 mmHg. This category is intended to identify individuals who are at increased risk of developing hypertension and cardiovascular disease.
- Stages of hypertension: The new definition maintains the traditional stages of hypertension (stage 1 and stage 2), but with slightly different blood pressure thresholds.
Why the Change?
The new definition is intended to better reflect the complexity of blood pressure and its relationship to cardiovascular disease. The previous definition, which was based on a single reading, may have missed individuals who were at risk of developing hypertension and cardiovascular disease.
What Does This Mean for You?
If you have a blood pressure reading of 120-129/80 mmHg, your healthcare provider may recommend lifestyle changes, such as:
- Regular exercise
- A healthy diet
- Weight loss
- Stress reduction
- Limiting sodium and alcohol intake
If your blood pressure is higher than 130/80 mmHg, your healthcare provider may recommend medication or other treatments to help manage your blood pressure.
Remember, it's essential to work with your healthcare provider to determine the best course of action for your individual situation.
