Home blood pressure monitoring

From Wikipedia, the free encyclopedia

Home blood pressure monitoring provides a measurement of a person's blood pressure at different times and in different environments, such as at home and at work, throughout the day. Home blood pressure monitoring may assist in the diagnosis of high or low blood pressure. It may also be used to monitor the effects of medication or lifestyle changes taken to lower or regulate blood pressure levels.

Home monitoring of blood pressure is especially useful for patients who suffer from white coat hypertension, where blood pressure levels are elevated in the Physicians office.

The 2003 US Joint National Committee recommends the use of self monitoring of blood pressure, before considering the more expensive ambulatory monitoring of blood pressure, to improve hypertension management.(Hypertension 2003;42: 1206-52) Both the Joint National Committee and the 2003 guidelines from the European Society of Hypertension and the European Society of Cardiology suggest that self monitoring might also be used as an alternative to ambulatory monitoring for the diagnosis of white coat hypertension. (J Hypertens 2003;21: 1011-531)

Recent studies (American Journal of Hypertension, May 2006) showed home blood pressure monitoring is as accurate as a 24 hour ambulatory monitoring in determining blood pressure levels. Researchers at the University of Turku, Finland studied 98 patients with untreated hypertension. They compared patients using a home blood pressure device and those wearing a 24hr ambulatory monitor. Researcher Dr. Niiranen said that, "home blood pressure measurement can be used effectively for guiding anti-hypertensive treatment". Dr. Stergiou added that home tracking of blood pressure, "is more convenient and also less costly than ambulatory monitoring".

The American Heart Association website states,"You may have what's called 'white coat hypertension'; that means your blood pressure goes up when you're at the doctor's office. Monitoring at home will help you measure your true blood pressure and can provide your doctor with a log of blood pressure measurements over time. This is helpful in diagnosing and preventing potential health problems."
