Shorter rest periods yield same results when measuring blood pressure
Current guidelines recommending five minutes of rest before a patient can receive a blood pressure screening may not be necessary for patients without high blood pressure. Average differences in blood pressure measurements obtained after zero or two minutes of rest were not significantly different (<+2 mm Hg) than readings obtained after five minutes of rest in people with systolic blood pressure <140 mm Hg. These findings illustrate the possibility for improvement in blood pressure screening efficiency, especially in busy health care settings. (2020-09-10)

Research findings held true even after adjusting for age, sex, race and ethnicity, education, smoking, alcohol use, cholesterol levels and waist fat, although to a lesser degree. (2020-09-10)

High blood pressure treatment linked to less risk for drop in blood pressure upon standing
Treatment to lower blood pressure did not increase and may decrease the risk of extreme drops in blood pressure upon standing from a sitting position. These findings suggest that orthostatic hypotension, a type of low blood pressure that occurs when moving from sitting or lying down to standing, should not be a reason to stop or reduce hypertension treatment. (2020-09-10)

Some health care professionals use outdated guidelines to screen and diagnose hypertension
Results of a survey show that some health care professionals are not following evidence-based guidelines, potentially leading to under and overdiagnosis of hypertension. 24-hour ambulatory blood pressure monitoring and home blood pressure monitoring are recommended before diagnosing hypertension; however, most health care professionals are using in-clinic measurements. (2020-09-10)

Treating hypertension lowers the risk for orthostatic hypotension, or drop in blood pressure upon standing
A systematic review of published evidence suggests that hypertension treatment lowers the risk for orthostatic hypotension, or extreme drop in blood pressure upon standing. Orthostatic hypotension, before or in the setting of more intensive blood pressure (BP) treatment, should not be viewed as a reason to avoid or de-escalate treatment for hypertension. This is important as it is traditionally thought that hypertension treatment causes this condition. (2020-09-10)

More than one drink a day may raise high blood pressure risk in adults with Type 2 diabetes
In a large study of adults with Type 2 diabetes, moderate drinking (defined as eight or more alcoholic beverages a week) was associated with a 60% or higher increased risk of high blood pressure. The severity of high blood pressure also increased with eight or more drinks per week. (2020-09-09)
