HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.Ocular Hypertension: A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.Risk Factors: An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.Pulmonary Artery: The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.Rats, Inbred SHR: A strain of Rattus norvegicus with elevated blood pressure used as a model for studying hypertension and stroke.Renin: A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.Intracranial Hypertension: Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.Blood Pressure Determination: Techniques for measuring blood pressure.Rats, Inbred WKY: A strain of Rattus norvegicus used as a normotensive control for the spontaneous hypertensive rats (SHR).Kidney: Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.Desoxycorticosterone: A steroid metabolite that is the 11-deoxy derivative of CORTICOSTERONE and the 21-hydroxy derivative of PROGESTERONE.Hypertrophy, Right Ventricular: Enlargement of the RIGHT VENTRICLE of the heart.

It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.Vascular Resistance: The force that opposes the flow of BLOOD through a vascular bed. It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT.Monocrotaline: A pyrrolizidine alkaloid and a toxic plant constituent that poisons livestock and humans through the ingestion of contaminated grains and other foods. The alkaloid causes pulmonary artery hypertension, right ventricular hypertrophy, and pathological changes in the pulmonary vasculature.

It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.Renin-Angiotensin System: A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.Aldosterone: A hormone secreted by the ADRENAL CORTEX that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium.Hyperaldosteronism: A condition caused by the overproduction of ALDOSTERONE.

It was developed by the Sprague-Dawley Animal Company.Persistent Fetal Circulation Syndrome: A syndrome of persistent PULMONARY HYPERTENSION in the newborn infant (INFANT, NEWBORN) without demonstrable HEART DISEASES. This neonatal condition can be caused by severe pulmonary vasoconstriction (reactive type), hypertrophy of pulmonary arterial muscle (hypertrophic type), or abnormally developed pulmonary arterioles (hypoplastic type). The newborn patient exhibits CYANOSIS and ACIDOSIS due to the persistence of fetal circulatory pattern of right-to-left shunting of blood through a patent ductus arteriosus (DUCTUS ARTERIOSUS, PATENT) and at times a patent foramen ovale (FORAMEN OVALE, PATENT).Cross-Sectional Studies: Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time.

Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.Chronic Disease: Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care.

(1/144) Plasma adrenomedullin and natriuretic peptides in patients with essential or malignant hypertension.

Adrenomedullin (AM), a potent vasodilator and natriuretic peptide, is found in human blood. To investigate the pathophysiological role of AM in essential and malignant hypertension (EHT and MHT), we measured the plasma concentrations of AM in patients with EHT of WHO stage I or II (n = 42) and in those with MHT (n = 9) by a specific radioimmunoassay, and compared these concentrations with those in normotensive controls (n = 46). The plasma concentrations of atrial and brain natriuretic peptides (ANP and BNP) in these subjects were also measured by immunoradiometric assays, and their relations to plasma AM were examined. The plasma AM level in the EHT patients (7.15+/-0.21 pmol/l, mean+/-SEM) was significantly (p < 0.01) higher than that in the normotensive controls (6.14+/-0.25 pmol/l), and a further elevation was observed in the MHT patients (14.1+/-3.8 pmol/l). Similar elevations of plasma ANP and BNP were seen in the two patient groups. The plasma AM level significantly (p < 0.01) correlated with not only the systolic (r = 0.44) and diastolic (r = 0.46) blood pressures, but also with the plasma levels of ANP (r = 0.43) and BNP (r = 0.43). The elevated plasma concentration of AM in the MHT patients decreased significantly (p < 0.05) after antihypertensive treatment, and the plasma ANP and BNP levels similarly declined. These results suggest that AM may participate, along with ANP and BNP, in mechanisms counteracting a further elevation of blood pressure in patients with EHT and MHT.  (+info)

(2/144) Haematospermia associated with malignant hypertension.

Haematospermia is generally regarded as a benign, self limiting condition. Although no obvious cause is found in most cases, an uncommon but important predisposing factor is severe uncontrolled hypertension. We describe a case illustrating the need to routinely measure blood pressure in such instances.  (+info)

(3/144) Nifedipine and arotinolol in combination for accelerated-malignant hypertension: results of one year follow-up.

The effects of a combined therapy with a calcium channel antagonist and alphabeta-blocker in patients with accelerated-malignant hypertension on blood pressure and renal function were examined. Thirteen patients presented with the clinical features of malignant hypertension (diastolic blood pressure >130 mmHg, retinal damage and progressive renal failure) at our hospital, over the 3 yr period from 1995 to 1997. These patients were treated with both a calcium antagonist, 60-80 mg/d dose of long acting nifedipine, and an alphabeta-blocker, 20 mg/d dose of arotinolol, for over 12 mo. At admission, the average blood pressure of the patients was 233+/-8/144+/-3 mmHg. The level of serum creatinine in these patients was 6.2+/-1.0 mg/dl. Intermittent hemodialysis therapy was introduced in 7 patients. Three days after treatment, blood pressure decreased to 162+/-4/102+/-4 mmHg. A month later, blood pressure decreased to 148+/-3/89+/-2 mmHg and serum creatinine levels were 3.6+/-0.4 mg/dl. Renal function in these patients improved, and they completely recovered from renal dysfunction, allowing withdrawal of haemodialysis therapy. One year later, the blood pressure in all of these patients was well controlled and no further renal deterioration was observed, except in one patient. Despite the reduction in blood pressure, one patient was on hemodialysis three times a week after 8 mo of treatment. From these finding, it is concluded that combination therapy with a calcium antagonist and alphabeta-blocker is effective in both the reduction of highly elevated blood pressure and protection of the kidneys, resulting in amelioration of accelerated-malignant hypertension.  (+info)

(4/144) Control of blood pressure and prevention of end-organ damage in patients with accelerated hypertension by combination with arotinolol and extended release nifedipine.

In patients with accelerated (malignant) hypertension, end-organ damage is the determinant factor for prognosis. Although recent advances in antihypertensive therapy have improved the outcome of patients with accelerated hypertension, the effectiveness of antihypertensive therapy still remains less convinced. In this study, we followed 13 patients clinically diagnosed with accelerated hypertension (defined as diastolic blood pressure > 130 mmHg, retinopathy with K-W IV and accelerated renal impairment) for 3 yr. One patient died due to acute myocardial infarction arising from poor compliance with antihypertensive therapy. One patient was maintained on hemodialysis for 3 yr. One patient was introduced for continuous ambulatory peritoneal dialysis (CAPD) for a year and then lived without dialysis therapy. The remaining 10 patients were followed for 3 yr. All patients were initially treated with intravenous administration of calcium antagonist for reduction of blood pressure, followed by hemodialysis therapy if needed. After stabilization of blood pressure, combination therapy with extended release nifedipine (40 to 80 mg daily) and arotinolol (20 mg daily) was started. The targets for blood pressure control were a systolic pressure of 135 mmHg and a diastolic pressure of 80 mmHg. If blood pressure control was unsatisfactory, guanabenz (2 to 4 mg before bedtime), a central acting drug, was added. At presentation, the mean diastolic blood pressure (mDBP) among the 10 remaining patients was 134 +/- 2 mmHg, the mean serum creatinine (mScr) was 4.5 +/- 0.7 mg/dl and the left ventricular mass index (LVMi) as measured by echocardiography was 150 +/- 9 g/m2. At 1 yr, the mDBP was reduced to 90 +/- 3 mmHg, the mScr to 2.9 +/- 0.9 mg/dl and the LVMi to 140 +/- 9 g/m2. At 3 yr, the mDBP was stabilized at 79 +/- 3 mmHg, the mScr maintained at 2.2 +/- 0.4 mg/dl, and the LVMi reduced to 128 +/- 9 g/m2. These results indicate that appropriate blood pressure control is important for improvement of renal impairment and cardiac damage in patients with accelerated hypertension. Moreover, combination therapy with arotinolol and extended release nifedipine may be beneficial for this purpose.  (+info)

(5/144) Antihypertensive therapy reduces increased plasma levels of adrenomedullin and brain natriuretic peptide concomitant with regression of left ventricular hypertrophy in a patient with malignant hypertension.

We investigated the potential role of increased plasma adrenomedullin and brain natriuretic peptide (BNP) levels in a patient with malignant hypertension. A 51-year-old man was admitted to our hospital with a chief complaint of visual disturbance. His blood pressure was 270/160 mmHg on admission. Papillary edema associated with retinal bleeding was observed. Echocardiography revealed marked concentric left ventricular hypertrophy with mild systolic dysfunction. Plasma levels of adrenomedullin and BNP were markedly elevated. Antihypertensive therapy reduced the plasma levels of adrenomedullin in association with a concomitant decrease in blood pressure. The plasma level of BNP also decreased and regression of left ventricular hypertrophy and normalization of left ventricular systolic function were observed. Our findings suggest that adrenomedullin may be involved in the defense mechanism against further elevations in blood pressure in patients with hypertension and that the plasma level of BNP may reflect left ventricular systolic dysfunction, left ventricular hypertrophy, or both, in patients with severe hypertension.  (+info)

(6/144) Atheromatous emboli in renal biopsies. An ultrastructural study.

In a series of 755 renal biopsies atheromatous emboli were found in biopsies of 8 men from 49 to 72 years of age. Unexplained recent deterioration of renal function was present in each. This previously unreported incidence of 8/755 biopsies is ascribed to the selection for biopsy of patients with unexplained decrease in renal function. Hypertension was a major feature in 6, hyperlipidemia in 2, a leaking aortic aneurysm in 1, carcinoma of the pancreas in 1, and chronic glomerulonephritis in 1 patient. Toluidine-blue-stained epoxy sections proved to be more effective in recognizing small emboli than paraffin sections. Ultrastructural observation concerned a) early lesions (eg, fresh emboli with endothelial distortion or injury), b) intermediate lesions (eg, histiocytic or giant cell reaction and intimal proliferation), and c) later lesions (eg, extraluminalization of the crystals eventually resulting in inert location in intimal stroma). Osmiophilic deposits on the crystal surfaces were myelin-form in structure and were felt to result from lysosomal action.  (+info)

(7/144) Malignant hypertension associated with use of oral contraceptives.

A 26-year-old woman who had been taking an oral contraceptive preparation for two years developed malignant hypertension. Investigation failed to elicit any renal or other cause for her hypertension, but control of blood pressure was obtained by withdrawal of the oral contraceptive agent and antihypertensive therapy. Subsequently, after withdrawal of therapy, the blood pressure remained near normal. The patient had a previous history of hypertension during pregnancy; she was also overweight.  (+info)

(8/144) Dyslipidaemia in patients with malignant-phase hypertension.

Low-density lipoprotein (LDL) consists of a heterogeneous group of particles of differing size, density and electrophoretic mobility, smaller particles being more atherogenic. A high proportion of small LDL particles is an independent risk factor for cardiovascular disease. We hypothesized that patients with malignant phase hypertension (MHT), the most severe form of hypertension, would demonstrate a more atherogenic LDL subfraction profile than either non-malignant hypertension (NMHT) or normotensive controls. We compared 16 patients with MHT to 41 patients with untreated NMHT and 45 normotensive controls. LDL subfraction profile was measured by disc polyacrylamide gel electrophoresis using a validated scoring system to calculate the mean size (locus) and heterogeneity (spread) of LDL subfraction mobilities. A higher LDL locus indicates a greater proportion of small LDL subfractions. LDL cholesterol levels were similar in all three groups (p=0.23). High-density lipoprotein cholesterol (HDL-C) levels were significantly lower (p<0.001) and serum triglyceride concentrations significantly higher (p=0.02) in the MHT group, compared to normotensive controls. LDL locus was greater in the NMHT group than in the normotensive controls and intermediate in the MHT group (p=0.008). There was no significant difference in LDL spread (p=0.26). Serum triglyceride concentrations were not significantly higher after adjusting for confounding variables. MHT is associated with an abnormal lipid profile, characterized by low HDL-cholesterol concentration. This dyslipidaemia may be partly responsible for the vascular complications and the poor prognosis of these patients.  (+info)
