| borderline hypertension | By consensus, that blood pressure zone between highest acceptable "normal" blood pressure and hypertensive blood pressure. The Framingham Heart Study defines this as pressures between 140 and 160 mm Hg systolic and 90 and 95 mm Hg diastolic. (05 Mar 2000) |
|---|---|
| pale hypertension | Hypertension with pallor of the skin, a severe form with pronounced constriction of peripheral vessels. (05 Mar 2000) |
| malignant hypertension | A severe form of acute hypertension that results in the abrupt rise in the blood pressure (diastolic pressure often over 120 mmHg). If left untreated, malignant hypertension can cause damage to the blood vessels in the eye, kidneys, brain and heart. Complications include stroke, heart attack, blindness and renal failure. Symptoms include headache, blurred vision, nausea, vomiting and lethargy. Neurologic symptoms are also a common finding. Malignant hypertension occurs more commonly in males, African Americans and those with a history for hypertension. (27 Sep 1997) |
| renal hypertension | Hypertension secondary to renal disease. (05 Mar 2000) |
| renovascular hypertension | Hypertension produced by renal arterial obstruction. (05 Mar 2000) |
| Goldblatt hypertension | Increased blood pressure following obstruction of blood flow to one kidney. Synonym: Goldblatt phenomenon. (05 Mar 2000) |
| portal hypertension | Any increase in the portal vein (in the liver) pressure due to anatomic or functional obstruction (for example alcoholic cirrhosis) to blood flow in the portal venous system. Indicators of portal hypertension are: oesophageal varices, haemorrhoids, enlarged veins on the anterior abdominal wall (caput Medusae) and ascites (fluid within the abdominal cavity). (27 Sep 1997) |
| portal hypertension: classification | <radiology> Presinusoidal, extrahepatic: portal vein obstruction (extrinsic compression, phlebitis, OC, coagulopathy, tumour invasion, pancreatitis, neonatal omphalitis), dynamic: traumatic/neoplastic arterioportal fistula, segmental portal hypertension: splenic/superior mesenteric vein occlusion, intrahepatic (obstruction of portal venules): congenital hepatic fibrosis, primary biliary cirrhosis, sarcoid, myelofibrosis, schistosomiasis, idiopathic noncirrhotic fibrosis, Wilson disease, reticuloendotheliosis, Felty syndrome, chronic malaria, toxic fibrosis (arsenic, copper, PVC vapors) sinusoidal, cirrhosis, sclerosing cholangitis postsinusoidal, Budd-Chiari syndrome, constrictive pericarditis, congestive heart failure (12 Dec 1998) |
| postcapillary pulmonary hypertension | <radiology> Heart: LV failure, mitral stenosis, LA myxoma / thrombus, cor triatriatum, Pulmonary veins: congenital stenosis of pulmonary vein origin, mediastinal granulomata and neoplasms, idiopathic pulmonary veno-occlusive disease, anomalous pulmonary venous return (12 Dec 1998) |
| postpartum hypertension | <obstetrics> Increased blood pressure immediately following the completion of labour. (05 Mar 2000) |
| precapillary pulmonary hypertension | <radiology> Vascular: increased flow (left to right shunts), decreased flow (tetralogy of Fallot), primary pulmonary hypertension, thromboembolic disease, pulmonary arteritides, Pleuropulmonary: emphysema, diffuse lung disease, fibrothorax, chest deformity, hypoventilation, high-altitude pulmonary hypertension (12 Dec 1998) |
| primary hypertension | Hypertension without known cause. Synonym: idiopathic hypertension, primary hypertension. (05 Mar 2000) |
| 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. (27 Sep 1997) |
| 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. (05 Mar 2000) |
| 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. (27 Sep 1997) |
