primary pulmonary hypertension |
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.

secondary hypertension |
Arterial hypertension produced by a known cause, e.g., hyperthyroidism, kidney disease, etc., in contrast to primary hypertension that is of unknown cause.

pulmonary hypertension |
<cardiology> Abnormally elevated blood pressure within the pulmonary circuit (pulmonary artery).
Pulmonary hypertension may be secondary to another disease process (VSD, ASD, severe COAD) or occur as a primary disease process known as primary pulmonary hypertension.

neonatal pulmonary venous hypertension |
<radiology> With cardiomegaly, hypoplastic left heart, critical aortic stenosis, cor triatriatum, pulmonary venous atresia, normal heart size, infradiaphragmatic TAPVR

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.

idiopathic hypertension |
Hypertension without known cause.
Synonym: idiopathic hypertension, primary hypertension.

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.

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.
