Hypertension is a disease of diverse causes. And which is manifested by sustained increases in blood pressure in systole and in diastole, or both.
The increase in blood pressure (hypertension) is a major cause, but most likely treatment of disease, and is divided into primary and secondary. In the general population, blood pressure is a continuous variable and its increase is associated with an increased risk of disease. Hypertension can be defined arbitrarily as a sustained diastolic pressure above 90 mmHg. However, there is no risk of developing diseases in which blood pressure is a pathogenic factor.
