Facts About Hypertension
Blood pressure is the pressure of blood pushing against the walls of your arteries. Arteries carry blood from your heart to other parts of your body.
Blood pressure normally rises and falls throughout the day, but it can damage your heart and cause health problems if it stays high for a long time. Hypertension, also called high blood pressure, is blood pressure that is higher than normal.
Facts About Hypertension in the United States
In 2017, the American College of Cardiology and the American Heart Association published new guidelines for hypertension management and defined high hypertension as a blood pressure at or above 130/80 mmHg. Stage 2 hypertension is defined as a blood pressure at or above 140/90 mmHg. 1
|Blood Pressure Category||Systolic Blood Pressure||Diastolic Blood Pressure|
|Normal||<120 mmHg||and||<80 mmHg|
|Elevated||120-129 mmHg||and||<80 mmHg|
|Stage 1||130-139 mmHg||or||80-89 mmHg|
|Stage 2||≥140 mmHg||or||≥90 mmHg|
- Having hypertension puts you at risk for heart disease and stroke, which are leading causes of death in the United States.2
- In 2020, more than 670,000 deaths in the United States had hypertension as a primary or contributing cause.2
- Nearly half of adults in the United States (47%, or 116 million) have hypertension, defined as a systolic blood pressure greater than 130 mmHg or a diastolic blood pressure greater than 80 mmHg or are taking medication for hypertension.3
- Only about 1 in 4 adults (24%) with hypertension have their condition under control.3
- About half of adults (45%) with uncontrolled hypertension have a blood pressure of 140/90 mmHg or higher. This includes 37 million U.S. adults. 3
- About 34 million adults who are recommended to take medication may need it to be prescribed and to start taking it. Almost two out of three of this group (19 million) have a blood pressure of 140/90 mmHg or higher.3
- High blood pressure costs the United States about $131 billion each year, averaged over 12 years from 2003 to 2014.4
Rates of High Blood Pressure Control Vary by Sex and Race
Uncontrolled high blood pressure is common; however, certain groups of people are more likely to have control over their high blood pressure than others.
- A greater percentage of men (50%) have high blood pressure than women (44%).3
- High blood pressure is more common in non-Hispanic black adults (56%) than in non-Hispanic white adults (48%), non-Hispanic Asian adults (46%), or Hispanic adults (39%).3
- Among those recommended to take blood pressure medication, blood pressure control is higher among non-Hispanic white adults (32%) than in non-Hispanic black adults (25%), non-Hispanic Asian adults (19%), or Hispanic adults (25%).3
Rates of High Blood Pressure Vary by Geography
High blood pressure is more common in some areas of the United States than in others. Below is a map showing the self-reported rate of hypertension by county. However, this map likely underreports the true effect of hypertension in each state, because about 1 in 5 adults with high blood pressure is unaware of it and would not report having it.5
The map shows that concentrations of counties with the highest hypertension prevalence – meaning the top quintile – are located primarily in Mississippi, Louisiana, Arkansas, Oklahoma, Texas, Kentucky, Tennessee, Alabama, Georgia, South Carolina, North Carolina, Virginia, Maine, and Michigan. Pockets of high-rate counties also were found in Florida, New Mexico, Arizona, Nevada, and Missouri.
