High blood pressure, often referred to as the “silent killer,” is a leading cause of heart attack and stroke in North America. In fact, it is one of the most common preventable causes of heart disease – which remains the number one cause of death for Americans – second only to smoking.
Past guidelines have advised individuals to check their blood pressure often, as part of routine preventative health care, and to track the results. The “high range” for blood pressure was traditionally 140/90 and a cause for concern worth visiting a doctor to discuss. However, recent revisions to the guidelines made by the American Heart Association and the American College of Cardiology have resulted in a lower threshold in what is considered “high.”
According to an article posted by the Toronto Star, “high blood pressure will [now] be defined as 130/80 millimeters of mercury or greater,” a change that will affect tens of millions of Americans who will now meet the criteria for the condition, and “will need to change their lifestyles or take medicines to treat it.”
High blood pressure is a very common health condition, affecting more than half of American adults. Just because it is common, however, does not make it any less harmful.
If you have high blood pressure, your heart is working extra hard to pump blood throughout your body, which can cause your arteries to become less elastic and scarred. Over time, untreated high blood pressure can cause your arteries to stiffen, and your heart to become stiffer and weaker, resulting in a possible heart attack, kidney failure or stroke.
High blood pressure is especially dangerous because many people do not experience known symptoms. The “silent killer” can be wreaking havoc on your body without you knowing anything’s wrong. The American Heart Association (AHA) reports that people often believe the myth that high blood pressure will display symptoms such as “nervousness, sweating, difficulty sleeping or facial flushing.” This is simply not true.
According to the AHA, “If you ignore your blood pressure because you think a certain symptom or sign will alert you to the problem, you are taking a dangerous chance with your life.”
The American Heart Association and the American College of Cardiology announced changes to the previous high blood pressure guidelines (which had not been revised since 2003) largely because of convincing data from a federal study published in 2015. The Toronto Star refers to the study, called Sprint, which compared “the safety and efficacy of intensive lowering of systolic blood pressure to <120 mm Hg versus routine management to <140 mm Hg.” The results showed overwhelming evidence of “significant cardiovascular benefit.”
The new guidelines affect every single adult in North America. Dr. Harlan Krumholz, a cardiologist at Yale University told the Toronto Star that “this is a big change that will end up labeling many more people with hypertension and recommending drug treatment for many more people.”
Here are some of the most startling statistics associated with the new guidelines:
Although there is no cure for high blood pressure, it is highly treatable with medication and lifestyle changes, including eating a healthier diet that is rich in fruits and vegetables and exercising more.
Lifestyle changes that may decrease blood pressure include:
