Experiments On Rats’ Neck Nerves Could Point To High Blood Pressure Solutions
Antihypertensive medications are the most commonly prescribed class of drugs in the United States and in 2010 totaled an estimated 678 million filled prescriptions, Christopher I. Li, M.D., Ph.D., of the Fred Hutchinson Cancer Research Center , Seattle , and colleagues write in the study background. “Evidence regarding the relationship between different types of antihypertensives and breast cancer risk is sparse and inconsistent, and prior studies have lacked the capacity to assess impacts of long-term use,” the study said. The population-based study in the three-county Seattle-Puget Sound metropolitan area included women ages 55 to 74 years: 880 of the women had invasive ductal breast cancer, 1,027 had invasive lobular breast cancer and 856 of them had no cancer and served as the control group. Researchers measured the risk of breast cancer and examined the recency and duration of use of antihypertensive medications. According to the results, current use of calcium-channel blockers for 10 or more years was associated with higher risks of ductal breast cancer and lobular breast cancer. The research is published by JAMA Internal Medicine, a JAMA Network publication.

dietary guidelines suggest people eat no more than 2,300 milligrams of sodium per day, while the AHA recommends an even lower threshold of 1,500 daily milligrams. The AHA estimates 97 percent of children and teens eat too much salt, putting them at risk for high blood pressure and eventual heart disease. For the study, researchers compared more than 3,200 kids between ages 8 and 17 who were part of a nutritional survey from 1988 and 1994 and compared them to more than 8,300 kids who were surveyed from 1999 to 2008. Researchers accounted for differences between the group that could affect the results, such as race, gender, body mass index and daily sodium intake. They found children with the highest sodium intake were 36 percent more likely to have elevated blood pressure than children with the lowest intake.

Blood Pressure Drug Tends to Slow Coronary Disease
Tony Heagerty, a professor of medicine at Manchester University who was not involved in the study, said it was an interesting development which could “potentially avoid the use of drugs which have to be taken on a daily basis for many years.” (Editing by Sonya Hepinstall) Also on HuffPost: Loading Slideshow Kiwis Research presented at a meeting last year of the American Heart Association shows that eating three kiwis a day is linked with decreased blood pressure. That study included 188 men and women age 55 and older, with slightly high blood pressure. They were instructed to eat three kiwis a day, or an apple a day for eight weeks. The researchers found that the people who ate the kiwis had lower systolic blood pressure levels than those who ate the apples. Kiwis are known to be rich in lutein, which means they have antioxidant properties.

Half of People With High Blood Pressure Don’t Know It
“We found that aliskiren had a moderate effect on reducing blood pressure, substantially reduced renin activity, and produced a compensatory increase in renin concentration in the blood plasma,” Dr. Nicholls said. “We also saw a bit of a trend toward regression in atherosclerosis. But our primary endpoint — a decrease in the volume of disease in the artery — did not meet statistical significance.” Although not a primary endpoint, the researchers did identify a decrease in major cardiovascular events including sudden death, stroke, and heart attack in patients on aliskiren.

High blood pressure risk rising among U.S. youths
It can alone reduce blood pressure by 2-4 mm Hg. One should reduce dietary sodium intake to no more than 100 mmol per day (2.4g sodium or 6g sodium chloride). It can alone reduce blood pressure by 2-8 mm Hg. One should engage in regular aerobic physical activity such as brisk walking (at least 30 min per day, most days of the week). It can alone reduce blood pressure by 4-9 mm Hg.

Blood Pressure: A silent killer
“Blood pressure-lowering drugs are generally inexpensive and commonly available treatments,” senior study author Dr. Salim Yusuf, a professor of medicine at McMaster University’s Michael G. DeGroote School of Medicine in Hamilton, Ontario, Canada, said in a university news release. “However, only a third of patients commenced on treatment are on enough treatment to control their blood pressure. This is worst in low-income countries, but significant in high- and middle-income countries, too.” The researchers led by the Population Health Research Institute (PHRI) of McMaster University and Hamilton Health Sciences examined data on 154,000 adults aged between 35 and 70. The participants, who did not have a history of heart disease or stroke , were from 17 different countries of varying economic strength. All participants had their blood pressure and medication use monitored.
