Blood pressure at night is higher than previously thought

Scientists at UCL have developed new technology which reveals that blood pressure measured close to the heart is much higher during sleep than previously thought. Night time blood pressure is a strong predictor of both heart disease and stroke, with previous studies establishing that blood pressure measured over the arm falls at night during sleep. However these new data indicate that the night-time decline in blood pressure may be less extensive than previously thought. ... Full story

The discovery could spur development of drugs capable of increasing this protein’s production without causing the severe side effects associated with glucocorticoids. ... Full story
