Blood pressure control improving. Statistics usually paint a gloomy picture of heart disease in America. Here's a ray of sunshine: The percentage of us who have our high blood pressure under control jumped from 29.2% in 1999 to 36.8% in 2007. If sustained, that jump will mean fewer cases of heart attack, stroke, and heart failure. The flip side is that almost two-thirds of those with high blood pressure don't have it under control. And almost one-quarter of Americans with high blood pressure don't know they have it. (Hypertension)

Folic acid. Bad news for folks counting on extra folic acid to keep their heart disease at bay -- it doesn't work. An analysis of a dozen large trials showed that folic acid didn't work any better than a placebo at preventing heart attack, stroke, or total cardiovascular disease in general, and had no effect on the overall number of deaths. Getting extra folic acid may work if started early, before heart disease gets a foothold, and it may prevent some types of cancer. But don't count on it yet. (Journal of the American Medical Association)
