Is Hypertension More Common Than We Think?

Changing Definitions

In 2017, the American College of Cardiology and American Heart Association redefined hypertension, lowering the threshold for diagnosis. This change meant that more people are now classified as having high blood pressure. Previously, hypertension was defined as having a systolic pressure of 140 mmHg or more, or a diastolic pressure of 90 mmHg or more. The new definition includes anyone with a systolic pressure of 130 mmHg or higher, or a diastolic pressure of 80 mmHg or higher.

Hypertension in the U.S.

In the United States, the prevalence of hypertension has jumped to about 45 percent for adults under the new guidelines. Previously, it was around 30 percent. Certain groups, such as older adults, Black adults, and those with obesity, are more likely to be affected. Despite the changes, hypertension remains a major health concern requiring effective management and control.

Global Impact

The change in definition has a global impact, with countries experiencing increased prevalence rates. For instance, Canada would see rates rise from 32 to 46 percent, while China's could increase from 25 to 50 percent. Different countries may adopt different guidelines, but the global burden of hypertension is expected to rise significantly.
