Brief description Blood pressure is controlled to a large extent by nerves, known as sympathetic nerves, that supply the heart and blood vessels. Measurements in humans have shown that the activity of sympathetic nerves is increased in a number of cardiovascular diseases, including heart failure and in many cases of high blood pressure. This has the effect of constricting blood vessels and increasing heart rate, which places an additional load on the heart which can cause damage to the heart. It is not known what causes this increased sympathetic activity, but one possibility is that it is due to the action of a circulating hormone called angiotensin, which acts on the brain, activating central nerve pathways which ultimately increase sympathetic activity. In this project we aim to test this hypothesis and thus help to unravel the mechanisms involved in the long term control of sympathetic activity and blood pressure.
