Applying the updated 2014 blood pressure (BP) guideline to the U.S. population suggests that nearly 6 million adults are no longer classified as needing hypertension medication, and that an estimated 13.5 million adults would now be considered as having achieved goal blood pressure, primarily older adults, according to a JAMA study released online to coincide with the 2014 American College of Cardiology Scientific Sessions.
Ann Marie Navar-Boggan, M.D., Ph.D., of Duke University Medical Center, Durham, N.C., and colleagues quantified the proportion of adults potentially affected by the updated 2014 recommendations, compared to the previous guideline, issued nearly 10 years ago (Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure [JNC 7]). The researchers used data from the National Health and Nutrition Examination Survey (NHANES) between 2005 and 2010 (n = 16,372), and evaluated hypertension control and treatment recommendations for U.S. adults. The new guideline proposed less restrictive BP targets for adults 60 years of age or older and for those with diabetes and chronic kidney disease.
- Stroke survivors who consistently control their blood pressure may reduce the likelihood of a second stroke by more than 50 percent.
- Less than a third of stroke survivors maintained consistent blood pressure control more than 75 percent of the time.
Stroke survivors who consistently control their blood pressure may reduce the likelihood of a second stroke by more than half, according to new research in the American Heart Association journal Stroke.
For the study, researchers analyzed the results from the Vitamin Intervention for Stroke Prevention (VISP) trial, which enrolled 3,680 ischemic stroke patients ages 35 and older in 1996-2003. Ischemic strokes are caused by a clot or other blockage in a blood vessel supplying the brain. Participants had been tested for several risk factors, including blood pressure levels at baseline, a month after the start of the study, at six months and every six months thereafter up to 24 months.
Eating a vegetarian diet appears to be associated with lower blood pressure (BP), and the diets can also be used to reduce blood pressure.

Factors such as diet, body weight, physical activity and alcohol intake play a role in the risk of developing hypertension. Dietary modifications have been shown to be effective for preventing and managing hypertension.
Individuals with normal BP in the clinic but elevated BP at home are at increased risk of death and cardiovascular events.
In an individual patient data meta-analysis of studies published before July 2013, Jan A Staessen and colleagues (University of Leuven, Belgium) found that patients with masked hypertension, or normal BP in clinic but elevated BP when measured at home, had an increased risk of death and cardiovascular events compared with those who had normal BP in both the clinic and at home.
The analysis included 5008 participants. While self-measured home BP was lower on average than clinic BP (mean home systolic BP 7.0 mm Hg and diastolic BP 3.0 mm Hg lower than the conventional blood pressure), 67 (5.0%) of those with optimal clinic BP (130/85) when BP was measured at home.

Researchers have found that a common class of blood pressure lowering drugs, i.e. beta blockers, could help to reduce the risk of Alzheimer’s disease and other types of dementia.
In this study, researchers worked on 774 elderly Japanese-American men, who took part in the Honolulu-Asia Aging Study. Researchers performed autopsies after the death of the participants.
Out of 774 participants, 610 were diagnosed with high blood pressure or taking medications for high blood pressure. Among the participants, who were treated (nearly 350), 15% of the participants were taking only a beta blocker medicine, 18% were taking beta blocker with other medications and the rest of the participants were taking other drugs only.
Researchers found that although all types of medications are important for the treatment of blood pressure but the participants, who were taking only beta blockers had fewer abnormalities in their brain as compared to the participants, who were either taking other medicines or not taking medicines. Participants taking beta blockers alone or in combination with other drugs showed significantly less shrinkage in their brains. Read more…
