Ocular hypertension. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [ 1][ 2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [ 3][ 4] Elevated intraocular pressure is an important risk ...
e. 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 ...
Hypertensive encephalopathy ( HE) is general brain dysfunction due to significantly high blood pressure. [3] Symptoms may include headache, vomiting, trouble with balance, and confusion. [1] Onset is generally sudden. [1] Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye.
Cardiology. Hypertensive heart disease includes a number of complications of high blood pressure that affect the heart. While there are several definitions of hypertensive heart disease in the medical literature, [1] [2] [3] the term is most widely used in the context of the International Classification of Diseases (ICD) coding categories.
Diagnosis. 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. [9] Hypertensive emergency differs from hypertensive urgency in that, in the former, there is evidence of acute ...
Strongly modulated blood flow pulse in central and branch arteries can result from hypertension. Microangiography by laser Doppler imaging [3] may reveal altered hemodynamics non-invasively. Mild signs of hypertensive retinopathy can be seen quite frequently in normal people (3–14% of adult individuals aged ≥40 years), even without ...
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 either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...
The African Society of Hypertension (AfSoH) Initiative is an international organization initiative with the objective to create the African Society of Hypertension with a main goal of providing a stable and organized African platform for scientific exchange in arterial hypertension. The AfSoH Initiative was created in 2010 by the consortium of ...
