Washington, October 11: A brand new examine reveals that girls have a decrease 'regular' blood strain vary in comparison with males, could also be detrimental to a lady's well being," said Susan Cheng, MD, MPH, MMSc, associate professor of Cardiology and director of the Institute for Research on Healthy Aging in the Department of Cardiology at the Smidt Heart Institute and senior author of the study. "Based mostly on our analysis outcomes, we advocate that the medical group reassess blood strain tips that don't account for intercourse variations."
The first number in a blood pressure reading is called the systolic pressure and measures the force of the blood against the artery walls as your heart beats. The second number is the diastolic pressure, the blood pressure against the artery walls between heartbeats. Intense Heat Waves in North India Can Harm High Blood Pressure Patients, Warn Experts.
For years, 120 mmHg has been considered the normal upper limit for systolic blood pressure in adults. Persistent elevations above this limit amount to hypertension-which is well known as the key risk factor for common cardiovascular diseases, such as heart attack, heart failure, and stroke.

In their newest study, Cheng and her research team examined blood pressure measurements conducted across four community-based cohort studies, comprising more than 27,000 participants, 54% of whom were women.
In doing so, the research team identified that while 120 mmHg was the threshold of risk in men, 110 mmHg or lower was the threshold of risk in women. Systolic blood pressure levels that were higher than these thresholds were associated with risk for developing any type of cardiovascular disease, including heart attack, heart failure and strokes.
Investigators also found that women had a lower blood pressure threshold than men for risk of each specific cardiovascular disease type, including heart attack, heart failure, and stroke.
"We are actually pushed to rethink what we thought was a standard blood strain which may hold a lady or a person protected from growing coronary heart illness or stroke," added Cheng, who also serves as director of Cardiovascular Population Sciences at the Barbra Streisand Women's Heart Center and is the Erika J. Glazer Chair in Women's Cardiovascular Health and Population Science.
These findings build on past research led by Cheng suggesting women's blood vessels age faster than men's. Cheng's research, published last year, confirmed that women have different biology and physiology than men and also explained why women may be more susceptible of developing certain types of cardiovascular disease and at different points in life.
With both the 2020 study and in their latest work, Cheng and her team compared women to women and men to men, rather than the common model of comparing women to men.
"If the perfect physiologic vary of blood strain really is decrease for females than males, present approaches to utilizing sex-agnostic targets for reducing elevated blood strain have to be reassessed," said Christine Albert, MD, MPH, chair of the Department of Cardiology at the Smidt Heart Institute. "This vital work is far-reaching and has quite a few medical implications."
