Cardiovascular System Holds A Key To Circadian Clock

Summary:
Heart attacks and strokes occur most commonly early in the morning when blood pressure is at its highest point in its 24 hour cycle. Scientists at the University of Pennsylvania School of Medicine have discovered another key to the body's circadian clock that may begin to explain these observations and lead to new treatments based on the body's timing mechanism.

Blood pressure varies in all of us throughout the day. This pattern, circadian variability, is exaggerated in patients who have high blood pressure, suggesting that the mechanisms which control this rhythm are disturbed.
