High blood pressure that's only a little above normal might increase the risk of stroke, researchers found. The researchers analyzed data from 12 studies with a total of 518,520 participants to assess the stroke risk of slightly elevated blood pressure, also known as prehypertension. The review was released online Wednesday in the journal Neurology . Almost one-third of the U.S. population is believed to have prehypertension, defined as systolic pressure between 120 and 139 and diastolic pressure between 80 and 89. Normal blood pressure is a systolic reading of less than 120, and a diastolic measure of less than 80. In general, the studies revealed that slightly elevated blood pressure was linked with a 50% higher risk for stroke compared with people with normal blood pressure, even after controlling for variables such as obesity, diabetes, smoking and age. In the seven studies that divided slightly high blood pressure into a low range (systolic pressure between 120 and 129 and diastolic pressure between 80 and 84)

The humble potato, much maligned lately, might have shot at redemption. A study finds that purple spuds might help obese and overweight people lower their blood pressure. The small crossover study, presented recently at the national meeting and exposition of the American Chemical Society in Denver, focused on 18 overweight or obese people who had high blood pressure. They ate six to eight small microwaved purple potatoes with skins (or biscuits containing an corresponding amount of potato starch)

Rob Evans, a 61-year-old social worker from Apache Junction, Ariz., got the good news on Father's Day: After 31/2 years, doctors had found him a heart and were preparing to bring it to UCLA, where he was being treated for a slow, steady decay of his cardiac muscle. Evans had been hospitalized at UCLA for six weeks. Excited, hopeful and anxious all at once, Evans dared imagine a different life: out in the garage remodeling his '69 Nova, riding his horse, wrestling with his grandson and helping his wife, Gail, take care of their barn instead of sitting, exhausted, in his chair all day. FOR THE RECORD: Doctor's name: An earlier version of this article misspelled the first name of Dr. Bartley Griffith, the director of heart and lung transplantation at the University of Maryland in Baltimore, as Bartely.

Strike another blow for refined carbs: A study released today finds that soy and milk protein supplements may be associated with lower blood pressure more than refined carbohydrate supplements. The study, published online in Circulation: Journal of the American Heart Assn. , put 352 adults who were at risk for high blood pressure or who had mild hypertension on various rounds of supplements. The participants were given 40 grams of powdered soy, milk or refined complex carb supplements daily for eight weeks, and had their blood pressure taken at various intervals during the trial.

America continues to get fatter, according to a comprehensive new report on the nation's weight crisis. Statistics for 2008-2010 show that 16 states are experiencing steep increases in adult obesity, and none has seen a notable downturn in the last four years. Meanwhile, cases of Type 2 diabetes and high blood pressure that health experts have long warned would result from the nation's broadening girth and sedentary ways are becoming increasingly widespread, according to the report, titled "F as in Fat," released Thursday.

A type of blood pressure-lowering medication known as angiotensin receptor blockers won’t increase a patient’s risk for cancer, the Food and Drug Administration said this week. So those taking the drugs for high blood pressure can just…relax. Concern about the drugs' possible link to cancer risk arose last year after an analysis of several studies suggested that angiotensin receptor blockers, or ARBs, might be associated with a slightly increased risk of cancer. But the FDA’s own research found no such connection, the agency said in an announcement Thursday: “This analysis included 31 trials and approximately 156,000 patients, far more than the approximately 62,000 in the published analysis.

About one in five young adults may have high blood pressure, a new study suggests, but many of them appear unaware of it. Such are the results of the latest attempt to clarify just how many far-from-elderly Americans are putting their long-term health at risk via hypertension. Researchers from the University of North Carolina at Chapel Hill analyzed blood pressure data from the National Longitudinal Study of Adolescent Health, called Add Health,...

High blood pressure often goes hand-in-hand with heart disease. But some people with heart disease don't have hypertension. Those people, however, may still benefit from taking medications to treat high blood pressure, according to an analysis published Tuesday in the Journal of the American Medical Assn. Experts reviewed 25 studies that examined the use of anti-hypertensive medications and prevention of heart attacks, strokes and death in people with heart disease but who had normal blood pressure.

I expect consequences from drinking lots of sugary sodas. Like: unneeded calories, possible spikes in blood sugar, slow but steady erosion of tooth enamel (if those oft-repeated science fair projects with the teeth in the plastic cup of Coke are to be believed) and caffeine jitters. But a rise in blood pressure? A study just published in the journal Hypertension argues that you might be in for that if you have a sugary-beverage habit. The finding comes from the so-called INTERMAP study, which stands for International study of Macro/Micronutrients and Blood Pressure, which kind of works as a name if you ignore words like “study” and “blood.

If you want to improve the health and fitness of your heart and blood vessels, you can. Basic lifestyle changes involving diet, exercise and smoking can make a big difference. It also helps to keep an eye on some key numbers, including blood pressure, cholesterol, body mass index and blood glucose. Last year, the American Heart Assn. winnowed all this advice into a checklist called Life's Simple Seven. For each item on the list, the AHA set criteria that define ideal cardiovascular health.
