Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [ 11 ] High blood pressure usually does not cause symptoms itself. [ 1 ] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as ...
The term hypertensive emergency is primarily used as a specific term for a hypertensive crisis with a diastolic blood pressure greater than or equal to 120 mmHg or systolic blood pressure greater than or equal to 180 mmHg. [ 10 ] Hypertensive emergency differs from hypertensive urgency in that, in the former, there is evidence of acute organ ...
But it doesn’t always have symptoms, so about one in three people don’t know they have it. Hypertension develops when the force of the blood coming from your heart consistently puts too much ...
Hypertension and the brain. Hypertension is a condition characterized by an elevated blood pressure in which the long term consequences include cardiovascular disease, kidney disease, adrenal gland tumors, vision impairment, memory loss, metabolic syndrome, stroke and dementia. [1] It affects nearly 1 in 2 Americans and remains as a ...
Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. [ 1 ] The most common cause of CVI is superficial venous reflux which is a treatable condition. [ 2 ] As functional venous valves are required to provide for efficient blood return from the lower extremities, this ...
Blood pressure(BP) is the pressureof circulating bloodagainst the walls of blood vessels. Most of this pressure results from the heartpumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [ 1 ][ 2 ] It is the most common type affecting 85% of those with high blood pressure. [ 3 ][ 4 ] The remaining 15% is accounted for by various causes of secondary hypertension. [ 3 ]
