While many people tend to put it off, it is recommended to schedule a yearly appointment with a physician to get a check up on your health. Illnesses that make us feel poorly, like the common cold, influenza, or an earache often send us to the doctor, but it is just as important to be evaluated when we are feeling healthy too.
Having a yearly assessment completed helps detect early signs and symptoms of common chronic problems, such as cardiovascular disease. For instance, hypertension, or high blood pressure, affects approximately one third of American adults and is the primary reason for over 40 million doctor visits each year.1 Based on new updates to blood pressure guidelines by the American Heart Association (AHA) and the American College of Cardiology (ACC), many adults may be facing a new diagnosis of hypertension.
Normal blood pressure is defined as having a systolic pressure (SBP) of <120 mmHg and a diastolic pressure (DBP) of <80 mmHg. Hypertension, or blood pressure above these values, is a serious condition that increases the risk of cardiovascular disease in the long term and is an ailment that should not be taken lightly.2 In fact, in the United States, hypertension accounts for more cardiovascular deaths than any other modifiable risk factor and comes only second to cigarette smoking as a preventable cause of death for any reason.2 For these reasons, prevention, early detection, and treatment is important.
Under the previous clinical recommendations that were published in 2003, patients were classified into either prehypertension (SBP 120-139 or DBP 80-89 mmHg), stage I hypertension (SBP 140-159 or DBP 90-99 mmHg) or stage II hypertension (SBP ≥160 or ≥100 mmHg) depending on their level of blood pressure elevation.3 In the updated guidelines released in November of 2017 by the AHA/ACC, the prehypertension category was eliminated and the criteria for stage I and II hypertension were lowered. Stage I hypertension is now defined as SBP 130-139 (or DBP 80-89 mmHg) and stage II hypertension is defined as SBP ≥140 (or DBP ≥90 mmHg).2,3 With these new changes, it is expected that approximately 50% of American adults may meet criteria for diagnosis of high blood pressure in the near future.
These new guidelines were partially prompted by recent clinical trials in which the focus was on treating patients with elevated blood pressures in two different manners, one of which required more intensive pharmacologic treatment.3 Patients that received more intensive therapy had a reduced risk of an acute cardiovascular event or death.3 While patients in the group treated more aggressively were at a higher risk for side effects such as hypotension (low blood pressure) and syncope (fainting), the benefit of treatment at a lower threshold outweighed the risk of these side effects.3
With this being the first update in clinical guidance for hypertension to come about in nearly 15 years, the question on the minds of many is, “How will this affect me?”. It is important to note that people are not suddenly sicker. The definition of what is or is not hypertension has just changed, therefore allowing us to start treating patients with a risk for future complications sooner and reduce the long-term cardiovascular risks. Often people cannot tell that their blood pressure is elevated without having it checked, so what is the best advice? Make appointments for yearly checkups and know your blood pressure numbers. If you currently have hypertension, are newly diagnosed, or think you may be at risk, talk to your physician or pharmacist about lifestyle changes and medications you can use to reduce your future risk of complications.
