No, 140/90 is no longer considered the normal threshold for high blood pressure in adults under current guidelines.
Understanding Blood Pressure Guidelines
Blood pressure readings are expressed as two numbers: systolic (the pressure when the heart beats) over diastolic (the pressure when the heart rests between beats). These readings are measured in millimeters of mercury (mm Hg).
Changes in Blood Pressure Guidelines
Previously, a blood pressure reading of 140/90 mm Hg or higher was considered to indicate high blood pressure (hypertension). However, updated guidelines from organizations like the American Heart Association (AHA) and the American College of Cardiology (ACC) have lowered this threshold.
Current Blood Pressure Thresholds
Adults are now generally considered to have high blood pressure if their readings are consistently at or above 130/80 mm Hg. Therefore, 140/90 mm Hg is now classified as Stage 2 Hypertension under the newer guidelines.
| Blood Pressure Category | Systolic (mm Hg) | Diastolic (mm Hg) |
|---|---|---|
| Normal | Less than 120 | Less than 80 |
| Elevated | 120-129 | Less than 80 |
| Stage 1 Hypertension | 130-139 | 80-89 |
| Stage 2 Hypertension | 140 or higher | 90 or higher |
| Hypertensive Crisis | Higher than 180 | Higher than 120 |
Implications of the Change
This change in guidelines means that more people may be diagnosed with high blood pressure than before. The intention is to identify individuals at risk earlier, allowing for lifestyle changes and, if necessary, medication to prevent more severe health problems.
In conclusion, while 140/90 mm Hg was previously considered the threshold for high blood pressure, current guidelines classify it as Stage 2 Hypertension, making it no longer the "new normal."
