The number of people in the U.S. with high blood pressure can actually be measured, a new study says.
That could lead to a way to better manage the condition without medications.
The study, published Wednesday in the journal Nature Medicine, found that people with higher blood pressure have a smaller number of red blood cells per milliliter of blood, meaning they can have a higher chance of developing blood clots in the blood vessels.
The researchers tested for red blood cell counts in the brains of more than 5,000 people over a 12-month period.
Researchers found a relationship between a person’s blood pressure and the number of cells per liter of blood.
The more red blood a person has, the more cells they have, and the greater the risk of blood clogging the arteries.
Red blood cells are tiny pieces of cells that help carry oxygenated blood from the heart to the muscles.
The type of blood that flows through the arteries is known as platelet, which can contain red blood and white blood cells.
The number and type of red cells also affect how much oxygen the blood supplies to the body.
Red cells contain about 30 to 60 percent oxygen and are believed to make up more than 90 percent of the oxygen that is carried in blood.
White blood cells make up the other half.
When people have too many white blood cell numbers, their blood vessels can become clogged.
Blood clots can also cause problems, such as strokes and heart attacks, that are sometimes fatal.
The scientists studied nearly 300 people with high or moderate blood pressure, a subset of people with hypertension.
Most of them had heart disease or high blood sugar levels.
They were tested for blood clumps and other biomarkers of blood clotting.
The results suggested that high blood-pressure patients who had lower numbers of red and white cells had fewer clots, and that people who had higher red and red cell numbers had more clots.
A small subset of the people had the highest blood pressure but no other problems, suggesting that they might have had normal platelet numbers.
“This study has implications for managing blood pressure in people who have high blood cholesterol,” said lead author and professor of epidemiology at the University of California, San Francisco, Dr. David Bock, a cardiologist.
The group analyzed data from about 3,000 U.T.C. students over a period of 12 months.
The students were followed over that time, and a blood sample was taken before and after each visit to the lab.
The team also asked participants to recall how they felt about the study, what they were wearing, how many drinks they had, and their body mass index (BMI) and the other risk factors.
They also assessed the blood pressure of participants over the course of the study.
The most common factors that people had to take into account were how much alcohol they had and whether they had any medical conditions, including diabetes, high blood glucose levels, high cholesterol levels, and other cardiovascular risk factors such as high cholesterol or hypertension.
The higher a person had a blood pressure over the 12-week study period, the lower their risk of having clots develop.
Blood pressure is one of the biggest risk factors for stroke, heart attack, and blood clotting, and it’s also one of those common symptoms of high blood clotts.
The findings have been backed by the American Heart Association, which says the risk for stroke is about three times greater for people with a high blood blood pressure than for people without.
“We don’t know the mechanism of the relationship between the blood pressures and the risk, but the findings are compelling,” said Dr. Andrew Kolodny, a professor of cardiovascular medicine at the Massachusetts General Hospital in Boston.
“The findings show that high BP, as measured by blood pressure tests, is associated with a lower risk of stroke, stroke risk factors, and even blood clumping in some cases.”
The new study, which involved 6,500 people over 18 months, included people who were enrolled in a study of blood pressure called the National Health and Nutrition Examination Survey (NHANES).
The researchers looked at data from 4,500 participants who had their blood pressure measured between 2007 and 2010.
Participants who were older, who had a family history of hypertension, and had a higher BMI were more likely to have high BP than younger, more healthy participants.
The people who did not have hypertension were also more likely than the people with diabetes to have a blood test for platelet counts, which measured the number and types of red, white, and black cells in the red blood.
Researchers did not examine blood pressure or the other markers that could predict the risk to have clots or stroke, but they did look at other risk variables, including BMI, blood pressure at the start of the year, and whether the participants had diabetes, heart disease, or high cholesterol.
“One of the things we found is that, while blood pressure was a risk factor for stroke and cardiovascular
