But the risk of death was nearly twice that for patients with white hypertension, compared with patients whose blood pressure is normal when in the doctor's office and at home, the report published in the New England Journal of Medicine on Wednesday [19659002"Whitecoathypertensionisnotbenign"DrHaithamAhmedmedicaldirectorofcardiologyrehabilitationattheClevelandClinicwhowasnotpartofthestudy"Whenawhitecoatraisesyourbloodpressuremanyotherstressorsareexpectedinlifeaswell"
Related researchers from the Autonomous University of Madrid, who persecuted 64,000 people over five years, concluded that regularly Blood pressure measurements performed at home are a stronger predictor of cardiovascular deaths than doctor readings.
"We do not want to dismiss white mantle hypertension," Dr. Raymond Townsend, director of hypertension program at Penn Medicine and author of the study's lead by e-mail. "We encourage our patients to measure blood pressure at home, which is a great way to not only monitor blood pressure where you actually" live ", but it also provides a lot of insight for patients as to the small life indiscretions -out chinese with extra soy sauce, can really affect your blood pressure the next day. "
What do the doctors suggest?
A 24-hour monitor that monitors blood pressure during the day to see if it's really elevated and talk to the doctor three months later. When choosing a home blood pressure device, the American Heart Association recommends a cuff style automatic upper arm monitor. Wrist and finger monitors are not recommended because they provide less reliable readings.
The right way to use a sphygmomanometer
- Be quiet. Do not smoke, drink caffeinated drinks, or exercise within 30 minutes before measuring your blood pressure. Empty your bladder and take at least 5 minutes rest before the measurements.
- Sit correctly – with your back straight and supported (on a dining chair and not on a sofa). Your feet should be flat on the floor and your legs should not be crossed. Your arm should be worn on a flat surface (such as a table) with the upper arm at heart level. Make sure the cuff is just above the elbow bend.
- Make sure she fits. Measure around your upper arm and choose a monitor that comes with the correct cuff.
- Measure every day at the same time.
- Take several measurements. Record the results.
- Do not measure over clothes .
When high blood pressure is recorded, it is important to measure two more measurements and wait a few minutes between measurements.
Blood pressure of 120/80 or higher is considered elevated; 130/80 to 139/89 is considered Grade 1 hypertension, and anything 140/90 or above is considered Stage 2 hypertension according to the American Heart Association and the American College of Cardiology.
When blood pressure reaches 180/120 or higher – and every count in blood pressure counts – people are classified as having hypertensive crisis with need for immediate treatment or hospitalization.
"Life is not free of stressors," Ahmed said. "That's what life is like, it's better that you control your blood pressure so that even as these stressors increase, it does not damage your blood vessels."
