Masked Hypertension May Result in Missed Opportunities to Prevent Hypertensive Heart Disease
Many patients unknowingly have what's called "masked hypertension," a condition whereby they have normal blood pressure readings in a hospital or clinic, but their pressure is elevated during normal living conditions. This type of hypertension is often associated with left ventricular hypertrophy and therefore is extremely important to detect and treat.
A recent study found that masked hypertension was nearly twice as prevalent (11.9%) among untreated blacks as untreated whites (6.8%). But it was also found to be common among both whites (17%) and blacks (20%) currently being treated for hypertension. What's more, these researchers found that high blood pressure at home was more predictive of left ventricular hypertrophy than high blood pressure in a clinic. The study's authors suggest that home blood pressure monitoring may be an important tool for diagnosing and providing appropriate treatment of hypertension and for the prevention of hypertensive heart disease.
In this study, researchers from Cedars-Sinai in Los Angeles and the University of Texas Southwestern Medical Center, among other institutions, evaluated the effectiveness of home blood pressure monitoring among non-Hispanic black and white men and women. The study included 917 untreated blacks versus 735 untreated whites, as well as 345 blacks being treated for hypertension and 193 whites being treated for hypertension.
iPhone and Other Home Blood Pressure Monitoring Devices Often Lack Accuracy and Reliability
Smartphones are helpful for directions and checking email, but research proves the same is not true for measuring blood pressure. According to research presented by Clarence E. Grim, M.D., of High Blood Pressure Consulting in Stateline, Nev., home b
