Is a 155 135 blood pressure safe

Blood pressure: normal values ​​are also dangerous

To this end, researchers working with Dingli Xu from Southern Medical University in Guangzhou, China, evaluated the data from 19 studies with a total of more than 760,000 participants. The observation periods ranged from four to 36 years.

Up to 95 percent higher risk of heart attack

It showed that people with a blood pressure between 120/80 and 140/90 mmHG had a 66 percent higher risk of a stroke compared to participants with lower values. Participants with high-normal values ​​(130-139 / 85-89 mmHg) even suffered a heart attack with a 95 percent higher probability. For people with normal blood pressure (120-129 / 80-84 mmHg) the risk was still 44 percent higher.

Values ​​that are below the threshold of 120/80 mmHg without impairing performance are considered to be optimal in terms of health. Mild hypertension starts at 140/90 mmHg, moderate at 160/100 mmHg. If it is more than 180/110 mmHg, high blood pressure is considered severe.

"If the results are confirmed, that would be an important message for the public," says study director Xu. Since the proportion of people with corresponding values ​​in the population is very high, appropriate measures could prevent many deaths.

Turn the lifestyle screw

"If blood pressure values ​​are high, those affected should think about changing their diet and exercising more," says the researcher. Such lifestyle changes could greatly reduce the risk of stroke in this group.

Medicines to lower blood pressure cannot currently be recommended to people in the normal-high blood pressure range. Because there is still too little research into how safe the therapy is for this group of patients and how great the benefits are.

High blood pressure (hypertension) is one of the widespread diseases. It is estimated that 50 percent of Europeans are affected. The number of unreported cases is probably much higher, because many people do not know that their blood pressure is too high. It is critical that these people remain untreated, because the pressure multiplies the risk of a stroke or heart attack. (cf)
