Some facts about Blood Pressure

Hypertension, or high blood pressure (also referred to as HTN or HPN) means chronically elevated pressure in the arteries that carry blood away from the heart to the whole body.

Blood pressure below 120/80 is considered normal. The level between 120/80 and 139/89 is treated as "pre-hypertension". To speak about high pressure, one should have constant readings of 140/90 or above. Some problem for people is choosing an automatic blood pressure monitor which suits their needs.

The first number indicates systolic pressure, or peak pressure in the arteries (when the heart pumps blood into them near the end of the cardiac cycle). The second number refers to the diastolic pressure, minimum pressure in the arteries in the moment of the heart relaxation. Low blood pressure is pressure so low it causes symptoms due to the low flow of blood through the veins and arteries.

Often associated with stresses, high blood pressure can be diagnosed also in patients that seem perfectly calm. It is true though that stress and emotional tension go hand in hand with occasional cases of hypertension.

The higher both numbers are (systolic and/or diastolic pressure), the higher is the risk of heart problems, atherosclerosis or arteriosclerosis, kidney failure, eye and brain damage. In fact, constant hypertension is associated with serious damage for every vital organ. The medical term for such a condition is "end-organ damage" indicating that it is the end result of a long process.
