Lowering high blood pressure without medication

For the first time, blood pressure in hypertensive patients could be reduced without medication: Scientists from Germany have succeeded in lowering the blood pressure of patients using a new method. The doctors sclerosed kidney nerves that are suspected of promoting high blood pressure.

In the case of particularly persistent high blood pressure, a small medical intervention could help to lower blood pressure in the future. In about every fifth patient, blood pressure medication does not help to permanently lower the pressure. Now scientists presented a new study at the American Heart Association's annual congress in Chicago, in which a marked reduction in blood pressure could be achieved by obliteration of the nerves on the kidneys.

Kidney nerves are sclerosed using catheters. A total of over 100 subjects from all over Europe and Australia took part in the study. So far, blood pressure medication has had no or insufficient effect on all study participants. The patients were divided into two different groups. Half of the group served as a comparison group and continued to take antihypertensive drugs. In the second group, renal nerves were sclerosed using a catheter. Here, highly frequented radio waves were emitted. A total of two nerves that were suspected of being responsible for high blood pressure were sclerosed during the treatment.

Study results successful At the beginning of the study, all participants had an average blood pressure of 178/98 mmHg. After only six months of the sclerotherapy method, blood pressure dropped by 32/12 mmHg. In the control group with the blood pressure medication, the blood pressure had increased even further. In addition to the successful values, the study authors pointed out that the new treatment method has no serious side effects. In addition, there were no complications during and after the procedure. "The current study is a milestone in hypertension therapy," said Prof. Dr. Lars C. Rump, director of the University Hospital Düsseldorf. Rump was instrumental in the development and implementation of the large-scale study. The results of the study clearly show "that we finally have a method at hand with which we can help patients who cannot be adequately treated with blood pressure medication simply and safely," said the doctor. Currently, however, the new form of therapy cannot fundamentally replace drugs. If there is no improvement despite the administration of different hypotensive agents, the kidney nerves should become obliterated. Optimal values ​​are values ​​below 120/80. One speaks of high blood pressure from a value of over 140/90 mmHg. The most severe stage of hypertension is then reached at values ​​exceeding 180/110 mmHg.

High blood pressure can lead to a heart attack. High blood pressure (hypertension) is a serious illness. If the blood pressure is permanently too high, serious illnesses such as heart attack or stroke can result. Hypertension is often noticed too late because patients experience hardly noticeable symptoms over a long period of time. Severe hypertension can cause symptoms such as headache, difficulty breathing in stressful situations and dizziness. If nosebleeds, palpitations and severe headache (especially the back of the head) occur, this indicates a possible high-pressure crisis. Those affected should immediately call an emergency doctor if they experience these symptoms. (sb, Nov 19, 2010)
