Gut Microbiome Mediates Hypertension

In mouse experiments, researchers have found a high-salt diet leads to depletion of a species of Lactobacillus in the gut, which in turn increases particular lymphocytes that result in a rise in blood pressure (and type 2 diabetes and atherosclerosis). Supplementation of the mouse diet with the depleted species of lactobacilli reversed these changes. A small study of salt-sensitive humans found similar…

New Hypertension Guidelines

The American College of Cardiology and the American Heart Association have defined three new categories of hypertension: Elevated blood pressure: 120-129 mm Hg systolic, <80 mm Hg diastolic Stage 1 hypertension: 130-139 mm Hg systolic or 80-89 mm Hg diastolic Stage 2 hypertension: >140 mm Hg systolic or >90 mm Hg diastolic Lifestyle modifications are recommended for…

Cardiovascular Response to Energy Drink

A pilot study found consumption of the energy drink, Rockstar, increased blood pressure in healthy young adult subjects. Within 30 minutes of consuming one can (16 oz), systolic blood pressure rose an average of 6.2% compared to 3.1% after a placebo drink. Diastolic blood pressure rose 6.8% vs. 0%. More research is needed to know…

Pistachios Help Stress

Penn State researchers randomized two groups of type-2 diabetics to different diets. All consumed a heart healthy diet, but the experimental group's diet included 2 daily servings of pistachios.  Researchers provided all the meals for 4 weeks. The blood vessels of those eating the pistachios remained more relaxed and open during a cold water challenge and…

Fitness Puts a Cap on Blood Pressure

Many people believe it is inevitable that the older they get the higher their blood pressure will be. A study which included almost 14,000 healthy men without hypertension, cardiovascular disease or cancer were followed for nearly 40 years. Highly fit men reached abnormal systolic blood pressures a decade later than men in the low fitness…

Long-term Blood Pressure Patterns Predict Later Disease

Blood pressures that are elevated at 25 years old and continue rising throughout young adulthood strongly predict subclinical atherosclerosis during middle age. Participants with elevated and increasing blood pressure profiles over the 25 year follow-up experienced 3.7 times the risk of coronary artery calcification at age 50 when compared to those who had low and stable pressures. …

Your Spouse’s Friends May Influence Your BP

It is recognized that an individual's own social relationships influences  their longevity.  Researchers studied the social network quality of 94 couples free of hypertension, heart disease, or psychological disorders. After adjustments, a greater number of supportive social ties was associated with lower blood pressure, and a larger number of aversive relationships were associated with higher blood pressure…

Check Your Kids’ Blood Pressure!

A 27 year long Finnish study of childhood hypertension strongly indicates it may raise the risk of atherosclerosis and heart disease in later life. High blood pressure in childhood appears to lay the groundwork for heart disease in adulthood--strong evidence for primary prevention activities to be initiated early in life. PositiveTip: If your child has…

Soy May Lower Blood Pressure

Individuals who consumed the most soy protein per day had lower systolic blood pressures than those who ate the least amounts, according to a new study. The top group consumed more than 2.5 mg per day of soy isoflavones. One cup of soy milk contains 22 mg of isoflavones, suggesting that soy consumption does not…

High Blood Pressure in College Freshmen Predicts Later Risk

Men enrolling at Harvard between 1914 and 1952 who reported elevated systolic blood pressure their freshman year experienced a 20% greater risk for coronary heart disease later in life. Those diagnosed with hypertension in middle age had twice the risk of coronary deaths and stroke compared to those with normal blood pressures.PositiveTip: Have you had…
