A study has found that people with hypertension, the most common form of the disease, are three times more likely to develop a blood pressure problem.
The study also found that it was possible to predict whether someone was at risk of developing a blood problem in a population.
It is not known why the blood pressure changes in people with the condition.
The researchers from the Medical Research Council and the University of Manchester looked at data from a population of more than 8,000 people.
They analysed the prevalence of hypertension in the UK over a period of 13 years and then compared this with the prevalence in people without hypertension.
They found that the risk of having a blood-pressure problem was about three times higher in people who had hypertension than in those without it.
This means people with high blood pressure are three to four times more at risk.
There is a link with heart disease, but it is not clear why this happens, Professor Jonathan Withers, of the Medical Royal Colleges, said.
“If you’re having a heart attack and your blood pressure drops, that could be because you’re at higher risk for a heart problem.”
It is thought that high blood pressures are linked to a greater risk of stroke, heart attack, or heart failure.
However, the new study did not link these risks to hypertension.
“The new results suggest there may be a relationship between high blood rates and hypertension, but that it is difficult to determine whether the relationship is causal or not,” Professor WitherS said.
People with hypertension may have a risk of complications from the disease.
They can suffer heart attacks and strokes, which can lead to problems with blood flow in the brain.
People at higher blood pressure have a higher risk of some types of heart disease including coronary heart disease.
But this is not yet clear.
The latest figures from the NHS show that people in the top fifth of the population had the highest average blood pressure in 2014-15.
Professor Wethers said that people at higher pressures could have more problems with the heart.
“They have a high risk of being at risk for heart disease,” he said.
The new research is published in the Journal of the American Medical Association.
The findings come as the NHS faces mounting pressure to cut spending, including on care for those with hypertension.
The health secretary, Jeremy Hunt, announced plans to raise the minimum wage to £8 an hour from the current £7.50, and announced plans last month to increase the proportion of people working in the public sector to 50 per cent.
But the proposals have been criticised by the National Union of Workers, who say they will cause hardship for thousands of workers.
