What is hypertension and its pathophysiology??? -

Hypertension or high blood pressure is a medical condition wherein the blood pressure is chronically elevated. While it is formally called arterial hypertension, the word quot;hypertensionquot; without a qualifier usually refers to arterial hypertension. Blood pressure is a continuously distributed variable, and the risk of associated cardiovascular disease likewise rises continuously. The point at which blood pressure is defined as hypertension is therefore somewhat arbitrary. Presently finding sustained blood pressure of 140/90 mmHg or above, measured on both arms is generally regarded as diagnostic.

Hypertension is the medical term for high bloodpressure. There is still much uncertainty about it s pathophysiology. A small number of people with hypertension have an underlying renal or adrenal disease as the cause for their raised blood pressure. In the remainder, however, no clear single identifiable cause is found and their condition is labelled quot;essential hypertensionquot;. A number of physiological mechanisms are involved in the maintenance of normal blood pressure, and their derangement may play a part in the development of essential hypertension.
