At the University of Reading we are interested in understanding the way the heart behaves under normal and diseased conditions. The heart is usually able to adjust its activities to a person's physical requirements, for example during exercise and at rest. Heart failure occurs when the heart is unable to meet these demands, and can happen in response to high blood pressure or following a heart attack.
Heart attacks and strokes often occur in the early part of the day. The cycle of day and night is likely to be important in heart function - it appears that sleep is as important as exercise and a good diet in keeping a healthy heart!
