As interest in probiotics has grown in recent years, some evidence has emerged that probiotics may favorably reduce blood pressure, but trials have been small and inconsistent. Now a meta-analysis published in Hypertension suggests that the blood-pressure lowering effects of probiotics may be genuine. Saman Khalesi and colleagues analyzed data from nine parallel, randomized, controlled trials including 543 […]

Although the device has not been approved in the U.S. — and will not be approved […]

SYMPLICITY HTN-3, the eagerly awaited first rigorous test of renal denervation, shows that the real effect of the novel blood-pressure-lowering technology is dramatically lower than earlier expectations, which had been fueled by data from previous uncontrolled trials. Results of SYMPLICITY HTN-3 were presented at the American College of Cardiology conference in Washington, DC, and published simultaneously […]

A new meta-analysis provides the strongest evidence yet that a vegetarian diet is strongly associated with lower blood pressure. Although various health benefits of a vegetarian diet have often been proposed, a rigorous examination of the effect on blood pressure has not been previously performed. In a paper published in JAMA Internal Medicine, Japanese researchers analyzed data from […]

Everyone knows that blood pressure is one of the most important measurements of cardiovascular risk. Less well known is that most studies of blood pressure have relied on single or isolated measurements of blood pressure. Few studies have even attempted to examine the significance of blood pressure patterns over a long period of time. Now, in […]
