High Blood Pressure Information and Research
High blood pressure, or hypertension, refers to high pressure in the arteries. Arteries are the canals that carry blood from the heart to the organs and when excessive pressure is applied over an extended period of time it can lead to a range of complications. High blood pressure can cause the arteries to stretch and as a result cause vascular weakness that can lead to strokes. Another complication can be vascular scarring that causes plaque and cholesterol to build up in the arteries, which is the predominant cause of heart disease. But there is hope for those that are concerned with high blood pressure, the disease is relatively easy to detected and treat. Normal blood pressure is considered to be below 120/80. Blood pressure between 120/80 and 139/80 is classified as "pre-hypertension" and a reading of 140/90 or above is considered hypertension. But what exactly do these numbers mean? The top number, the larger of the two, is the pressure on the arteries as the heart contracts and pushes blood forward into the arteries. This is known as the systolic pressure. The bottom number is known as the diastolic pressure and it represents pressure when the heart is relaxed after a contraction. An elevation in the diastolic pressure (the bottom number) was considered more of a medical concern, but it is now believed that systolic elevations are a concern for adults over the age of 50. There are a number of ways a person can combat the issue of high blood pressure. A physician should recommend a change in lifestyle before administering medication. A healthy diet and regular exercise can significantly impact high blood pressure.
