New Hypertension Guidelines Could Save Lives and Money

View | Comment

Full implementation of new hypertension guidelines could prevent 56,000 cardiovascular disease events (mostly heart attacks and strokes) and 13,000 deaths each year, without increasing overall health care costs, an analysis conducted by researchers at Columbia University Medical Center found. The paper was published today in the online edition of the New England Journal of Medicine.

Analysis Rejects Linkage Between Testosterone Therapy And Cardiovascular Risk

View | Comment

Fears of a link between testosterone replacement therapy and cardiovascular risk are misplaced, according to a review published in this month’s Mayo Clinic Proceedings. The therapy has come under widespread scrutiny in recent months, including by a federal Food and Drug Administration (FDA) panel convened last fall.

High Cholesterol In 30s, 40s, Increases Later Risk Of Heart Disease

View | Comment

Most young adults might assume they have years before needing to worry about their cholesterol. But new findings from researchers at the Duke Clinical Research Institute suggest that even slightly high cholesterol levels in otherwise healthy adults between the ages of 35 and 55 can have long-term impacts on their heart health, with every decade of high cholesterol increasing their chances of heart disease by 39 percent.

Researchers have shown that neonatal mouse hearts have varying regenerative capacities depending upon the severity of injury. Approaches to extend this regenerative capacity in a mammalian model, from the neonatal period to the juvenile or adult period, could help identify new treatment options for humans.
