ScienceDaily (Dec. 8, 2008) — Researchers have new evidence to show that the heart beats to its own drummer, according to a report in the December issue of the journal Cell Metabolism. They've uncovered some of the molecular circuitry within the cardiovascular system itself that controls the daily rise and fall of blood pressure and heart rate. The findings might also explain why commonly used diabetes drugs come with cardiovascular benefits, according to the researchers.
