In spontaneously hypertensive rats resistance artery structure, endothelial dysfunction and geometry-independent wall stiffness were reduced by an angiotensin AT(1)-receptor antagonist. In previous studies of human hypertension, interruption of the renin-angiotensin system corrected small artery structure and endothelial dysfunction, whereas the beta-blocker atenolol did not. We hypothesized th...
BACKGROUND Angioedema is a well-known adverse effect of angiotensin-converting enzyme inhibitors. The bradykinin accumulation as a result of the decreased degradation of bradykinin is thought to be the causal mechanism. Angiotensin II antagonists seem to have no effect on the degradation of bradykinin. Therefore, it was expected that angioedema would not occur during treatment with losartan pot...
BACKGROUND Losartan, a drug with antiinflammatory properties, has been shown to prevent ischemic injury in various organs. The purpose of the present study was to investigate the effects of losartan on ischemic skin flaps and on flap survival. METHODS A 3x9 cm dorsal flap was elevated in 24 Sprague-Dawley rats. Rats received the following treatment for seven days: Group I (n=8): 10 mg/kg losa...
The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study reported that a losartan-based antihypertensive regimen reduced cardiovascular morbidity and mortality (composite of cardiovascular death, stroke, and myocardial infarction) more than therapy based on atenolol in patients with left ventricular hypertrophy and isolated systolic hypertension (ISH). Patients aged 55-80 y...
Objective: We performed a prospective, randomized clinical study to assess whether prophylactic treatment with metoprolol or losartan, initiated soon after lung cancer surgery in patients with elevated N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, reduces the incidence of postoperative atrial fibrillation. Background: Postoperative atrial fibrillation is a well recognized complic...
We reported that the AT1 receptor antagonist losartan decreases arterial pressure in sodium-replete rats and that this response is attenuated in area postrema-lesioned (APx) rats (J. P. Collister, B. J. Hornfeldt, and J. W. Osborn. Hypertension 27: 598-606, 1996). In that study, food intake for the 3-wk period after sham lesion was restricted to that observed in APx rats. Food-restricted sham r...
AIM The aim of this study was to investigate the effects of pioglitazone and losartan pre-treatment on the aortic contractile response to the alpha-1 agonist, phenylephrine, and the alpha-2 agonist, clonidine, in L-NAME-induced hypertensive, STZ-induced diabetic, and hypertensive diabetic rats. METHODS Male Wistar rats were randomly allocated to four groups: control, diabetic (DM), hypertensi...
BACKGROUND The study RENAAL (Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan) demonstrated that Losartan was more effective lo reduce the progression of kidney disease in diabetic patients with proteinuria and a reduction in glomerular filtration rate. AIM To perform a cost benefit analysis of Losartan use from provider and payer points of view. MATERIAL AND METH...
The present study aimed to determine the inhibitory effects of angiotensin II (AngII) on angiopoietin‑like protein 2 (Angptl2) in rat primary cardiomyocytes, and to investigate the potential association between angiotensin II type 1 receptor (AT1R) and these effects. Cardiomyocytes were isolated from 3-day-old Wistar rats, and were cultured and identified. Subsequently, the expression levels of...
BACKGROUND/AIMS In liver cirrhosis/portal hypertension, collaterals as varices may bleed and are influenced by vasoresponsiveness. An angiotensin blockade ameliorates portal hypertension but the influence on collaterals is unknown. METHODS Portal hypertension and cirrhosis were induced by portal vein (PVL) and common bile duct ligation (BDL). Hemodynamics, real-time PCR of angiotensin II rece...
