The World Health Organization (WHO) recommends that blood pressure is measured by a blood sample every three months.
That’s fine for people who have already been diagnosed with the condition, but the WHO recommends that anyone with a history of hypertension who’s not well and isn’t using blood pressure medication should get a test done at least once a year.
If your blood pressure doesn’t change, then you might be at a higher risk of heart disease, according to a new study from the University of Pennsylvania.
Researchers analyzed data from over 1.5 million people from the Framingham Heart Study and found that those with high blood pressure who did not get a regular blood pressure test during the first two years of follow-up were significantly more likely to have heart disease.
The researchers analyzed data on 1,049,942 people from around the world and found higher rates of heart attacks among people who had not been diagnosed by a doctor with hypertension.
The researchers found that for people with a high blood volume, the average blood pressure rose about 3 mm (0.4 inches) every three years.
That means someone with a blood volume of 200 milliliters (5.4 ounces) would see their blood pressure rise about 5.2 mm (1.3 inches) a year, which is roughly equal to a person with a normal blood pressure.
The increase in blood pressure for people whose blood pressure did not change was even higher, with the average increase for people without hypertension being 14.7 mm (4.2 inches).
In the study, researchers also examined the association between blood pressure and cancer risk.
Those with high levels of blood pressure were 2.5 times more likely than those without hypertension to develop cancer, even after adjusting for other risk factors.
The study found that the increased risk of cancer was significantly higher in those with a family history of cancer, the researchers said.
The study was published online July 24 in the journal Archives of Internal Medicine.
