Hypertensive kidney disease is a medical condition referring to damage to the kidney due to chronic high blood pressure. It manifests as hypertensive nephrosclerosis (sclerosis referring to the stiffening of renal components). [ 2] It should be distinguished from renovascular hypertension, which is a form of secondary hypertension, and thus has ...
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]
avoidance of smoking, limited alcohol intake, reduced intake of salt and caffeine. Labile hypertension occurs when there are unexpected changes in blood pressure. The term can be used to describe when people have blood pressure measurements that abruptly fluctuate from being abnormally high, approximately 140/90 mm Hg or over and returns to its ...
In addition, hypertension precedes heart failure in 90% of cases, [7] and the majority of heart failure in the elderly may be attributable to hypertension. [17] Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading ...
Hypertensive crisis. Severely elevated blood pressure (equal to or greater than 180 mmHg systolic or 120 mmHg diastolic) is referred to as a hypertensive crisis (sometimes termed malignant or accelerated hypertension), due to the high risk of complications. People with blood pressures in this range may have no symptoms, but are more likely to ...
Pulmonary veno-occlusive disease ( PVOD) is a rare form of pulmonary hypertension caused by progressive blockage of the small veins in the lungs. [ 2] The blockage leads to high blood pressures in the arteries of the lungs, which, in turn, leads to heart failure. The disease is progressive and fatal, with median survival of about 2 years from ...
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 ...
