High blood pressure: lower blood pressure is not always healthy

In some patients, blood is not to reduce pressure healthy

People with high blood pressure are advised to reduce this, to reduce the risk for cardiovascular diseases such as heart attack. But German researchers have now found that it is the same for all patients advised if your blood pressure is adjusted to the applicable guideline values.

The risk of death increases

Doctors have so far assumed that it is for older people to be healthier, if your blood pressure is set to below 140/90 mmHg. But researchers from the Charité – Universitätsmedizin Berlin have found that this acceptance of patients applies to all high blood pressure. On the contrary, In the case of persons older than 80 years or who had already had a stroke or a heart attack, increases the risk of death even.

Changes In Blood Pressure Reference Values

As the professional Association of German internists (BDI) on its website, “the internist in the network” writes, about 70 to 80 percent of the more than 70-Year-olds with elevated blood pressure, which can in the long term, pull-threatening cardiovascular life diseases such as heart attack or stroke.

In deciding whether and how Physicians treat people with hypertension, follow the recommendations of the professional societies.

With over 65 Years of blood pressure according to the European guidelines below 140/90 mmHg, in order to protect them from life-threatening heart diseases.

These target values also apply to people over 80 to take account of Year, you are, however, more and more individual factors such as concomitant diseases.

In the U.S., new blood will apply for 2017 pressure-indicative values. Professional societies such as the American College of Cardiology (ACC) and the American Heart Association (AHA) recommended for all hypertensive patients older than 65 years, an adjustment of the blood pressure below 130/80 mmHg.

What are the target values, but actually for the treatment of older people with high blood pressure are the best, is the subject of a current scientific debate.

Basically no protective effect

Researchers at the Charité were now able to show in an observational study, the drug lowering blood pressure to below 140/90 mmHg – and, in particular, under 130/90 mmHg – generally has a protective effect.

The basis of the analysis of epidemiological data from over 1,600 women and men that were at the beginning of the study in the year 2009 at least 70 years old and taking blood pressure-lowering treatment.

As the scientists were scientists, had in the over 80-Year-olds, those whose blood pressure at below 140/90 mmHg, a 40 percent higher risk of death than those whose blood pressure is above 140/90 mmHg.

A similar observation of the team of researchers made the participants of the study who had suffered in the past, a stroke or heart attack:

In the case of those whose blood pressure at below 140/90 mmHg increased the mortality risk by 61 percent compared to those whose blood pressure remained despite the medical treatment above this limit value.

The results of the study were published in the scientific magazine “European Heart Journal”.

“Our results make it clear that the treatment of elevated blood should be adapted to the pressure in these groups of patients individually,” said Dr. Antonios Douros from the Institute of Clinical pharmacology and toxicology at the Charité in a message.

“We should of agreement, the recommendations of the professional societies to apply a flat rate in all patient groups,” said the first author of the study.

About the study

The data suggest that the epidemiological data have been collected in the framework of the “Berlin Initiative study”, which is headed by Prof. Dr. Elke Schäffner, Deputy Director of the Institute for Public Health at the Charité,,.

Her Team, the study participants interviewed every two years to their diseases and medications, measure blood pressure and kidney function and analysed blood and urine.

After six years, was investigated with statistical methods, to what extent, prior to the beginning of the measured blood pressure with death.

Also the influence of factors such as gender, Body Mass Index, Smoking status, alcohol consumption, Diabetes, and the number of antihypertensive agents were taken into account.

“Next, we want to investigate which groups of patients of a blood pressure-lowering actually benefit,” said Prof. Schäffner. (ad)
