This Is The Ideal Blood Pressure That Prevents Heart Disease, Says New Study
You've probably heard high blood pressure, or hypertension, is called a "silent killer," and that's for good reason. When the blood pumping through your body is pressing too hard against blood vessel walls, it can put your life at risk—but the condition is often asymptomatic, giving you no clues you're in danger. Hypertension is also one of the largest risk factors for cardiovascular disease and stroke, the former of which is the leading cause of death around the world according to the World Health Organization.
Though it's silent but deadly, high blood pressure is largely preventable with a healthy diet and getting regular exercise are two habits doctors widely recommend. In the U.S., doctors widely recommend a blood pressure of 120/80 as the safe zone to aim for.
But globally, that "ideal" metric varies, as two Korean medical researchers point out in a new study. For example, American and Taiwanese guidelines recommend a target systolic blood pressure level—or the top number in a blood pressure reading, which shows the pressure at which blood is leaving the heart—of less than 130 mmHg. (mmHg is the unit of measurement for blood pressure, measuring amount of mercury per millimeter. Meanwhile, diastolic blood pressure reveals the pressure of blood vessels when the heart is at rest between beats.) However, guidelines issued in Europe and China suggest a target systolic blood pressure level range between 130 and 139 mmHg and advise against it dropping below 130 mmHg.
A new retrospective cohort study published in JMIR Public Health & Surveillance sought to identify that golden number by analyzing data from the National Health Insurance Service (NHIS) database. The researchers included data from 68,901 Korean patients older than 65 years who were newly diagnosed with hypertension, had at least one NHIS check-up between 2003-2004, and had at least two check-ups during the follow-up period through 2020.
The researchers divided the participants by the 10 mmHg increment range of their systolic blood pressure levels at the first check-up:
During the follow-up period, the researchers recorded the number of deaths in each group due to cardiovascular disease:
…as well as deaths that occurred due to other health complications:
These findings revealed that participants with systolic blood pressure levels between 120 and 139 mmHg experienced the lowest rates of all-cause mortality, as well as the lowest rate of deaths related to cardiovascular disease.
According to the researchers, most guidelines for managing hypertension do not currently include a safe lower limit for blood pressure. However, this study also suggests that there could be a minimum recommended systolic blood pressure level for people with hypertension, as rates of all-cause mortality and deaths from cardiovascular disease rose for participants with a reading below 120 mmHg.
So, it may not be a huge surprise that your doctor's recommendation aligns with global data. However that may be reassuring, while it's also worth understanding why around the world, blood pressure is a key metric medical professionals want their patients to keep in check.
Cuffless Monitor Offers Promise For Hypertension Management
A study led by a Brigham investigator evaluated a novel device that automatically measures blood pressure at the wrist, generating hundreds of readings within days that may help clinicians determine cardiovascular risk and improve hypertension care
High blood pressure, the leading risk factor for death worldwide, is present in one in every two adults. Only one-quarter of individuals with hypertension have their blood pressure under control, highlighting the need for innovative strategies for blood pressure management. A study led by an investigator from Brigham and Women's Hospital, a founding member of the Mass General Brigham healthcare system, evaluated a cuffless monitor that uses optical sensors to record blood pressure continually and efficiently, without disruption to the patient. The study, published in Frontiers in Medicine, highlights promising advancements in hypertension diagnosis, risk assessment and management that may be enabled by use of cuffless devices.
The successful management of hypertension depends on patients being able to take blood pressure measurements easily and reliably outside of the traditional doctor's office setting. Cuffless devices have the potential to revolutionize hypertension management. They provide many more readings than traditional devices, during both the day and night, which can help confirm the diagnosis of hypertension and guide medication titration."
Naomi Fisher, MD, corresponding author of the Division of Endocrinology, Diabetes and Hypertension at Brigham and Women's Hospital
Medical guidelines increasingly recommend the incorporation of at-home blood pressure monitoring into hypertension diagnosis and management. This is because isolated blood pressure readings taken at a clinician's office may be inaccurate: for some, blood pressure tends to rise in medical settings ("white coat hypertension") while others have normal blood pressure during examination despite hypertensive readings at home ("masked hypertension").
Time-in-target-range (TTR) describes how often a patient's blood pressure is in the normal range, and it is emerging as a promising metric of cardiovascular risk. But TTR requires more frequent blood pressure readings that can feasibly be obtained by patients with traditional blood pressure cuffs, which can be inconvenient, burdensome and sometimes uncomfortable for patients.
Fisher, who designed and led the study, collaborated with co-authors from Aktiia SA, a Swiss biotechnology company, to analyze over 2.2 million blood pressure readings from 5,189 subjects in Europe and the U.K. Who wore a cuffless wrist monitor manufactured by Aktiia. On average, the Aktiia device collected 29 readings per day, a substantial increase from the number of blood pressure readings patients typically take with home devices (guidelines recommend four per day, which is more than most patients measure). Over a 15-day period, the researchers obtained an average of 434 readings from each patient.
By calculating TTR over a 15-day period, the researchers were able to risk stratify participants by percentage of readings in target range and compare these classifications to those generated via traditional measurement patterns, using either 24-hour or week-long daytime monitoring schedules. They found that the traditional methods misclassified 26 and 45 percent of subjects, respectively, compared to the reference TTR. They determined that continual monitoring for seven days is required to obtain 90 percent or greater accuracy in hypertension risk classification, a frequency of measurement that may only be possible with cuffless monitors.
Though the cuffless device studied here has not been approved by the U.S. Food and Drug Administration, it has been validated in multiple studies and is available for over-the-counter purchase in Europe and the U.K. Work to evaluate and set standards for such devices in the U.S. Is ongoing.
"For the first time, by using a cuffless device, we can collect continual out-of-office blood pressure readings and use these data to calculate a new metric, time-in-target-range, which shows great promise as a predictor of risk," Fisher said. "The use of cuffless devices could create a shift in the paradigm of blood pressure monitoring and hypertension management."
