| T + 1, T + 2, T + 3 | first, second, and third stages of increased intraocular tension |

| hypertension | <cardiology> Persistently high arterial blood pressure. Hypertension may have no known cause (essential or idiopathic hypertension) or be associated with other primary diseases (secondary hypertension). This condition is considered a risk factor for the development of heart disease, peripheral vascular disease, stroke and kidney disease. (29 Sep 1997) |
|---|---|
| hypertension, malignant | Severe hypertension characterised by papilledema and necrosis of small arteries and arterioles. The diastolic pressure is generally greater than 130 mm hg. (12 Dec 1998) |
| hypertension, portal | Abnormally increased pressure in the portal venous system; frequently seen in cirrhosis of the liver and in other conditions which cause obstruction of the portal vein. (12 Dec 1998) |
| hypertension, pulmonary | High blood pressure in the pulmonary arteries. Normally, the pressure in the pulmonary arteries is low (compared to that in the aorta). Pulmonary hypertension can irrevocably damage the lungs. Pulmonary hypertension is made up of pulmonary for lung, hyper for high, and tension for blood pressure. (in french, the word for blood pressure is tension ). (12 Dec 1998) |
| hypertension, renal | Hypertension due to renal diseases, especially chronic parenchymal disease. Hypertension as a result of compression or obstruction of the renal artery or its branches is hypertension, renovascular. (12 Dec 1998) |
| hypertension, renovascular | Hypertension due to compression or obstruction of the renal artery or its branches. (12 Dec 1998) |
| neonatal pulmonary venous hypertension | <radiology> With cardiomegaly, hypoplastic left heart, critical aortic stenosis, cor triatriatum, pulmonary venous atresia, normal heart size, infradiaphragmatic TAPVR (12 Dec 1998) |
| systemic venous hypertension | Increased pressure in the veins ultimately leading to the right atrium nearly always due to disease of the right heart but occasionally due to blockade of one or both venae cavae. (05 Mar 2000) |
| idiopathic hypertension | Hypertension without known cause. Synonym: idiopathic hypertension, primary hypertension. (05 Mar 2000) |
| idiopathic pulmonary hypertension | <chest medicine> A condition where there is increased blood pressure in the pulmonary arteries with otherwise normal heart and lungs. The cause is unknown, but there is diffuse narrowing of the pulmonary arteries resulting in increased arteriolar pressures. Secondary heart failure ensues without correction of this problem. There is an increased incidence of this disease in females between the ages of 20 and 40 years. Treatment may include a heart and lung transplant in select cases. (27 Sep 1997) |
| intracranial hypertension | Increased pressure of the cerebrospinal fluid. If symmetrically distributed it may have few neurologic symptoms (e.g., pseudotumour cerebri), but if it is asymmetrical (as in hydrocephalus), neurological symptoms are often severe. (12 Dec 1998) |
| ocular hypertension | A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma. (12 Dec 1998) |
| essential hypertension | Hypertension without known cause. Synonym: idiopathic hypertension, primary hypertension. (05 Mar 2000) |
| labile hypertension | Frequently changing levels of elevated blood pressure. (05 Mar 2000) |
