Impaired left lower lobe ventilation in patients with cardiomegaly. An isotope study of mechanisms.

Numai utilizatorii înregistrați pot traduce articole

Reduced left lower lobe ventilation (V) in patients with enlarged hearts has been commonly observed on routine isotope ventilation-perfusion lung scanning, and there is evidence to show that this reduction is dependent on posture. Clinically, it may have a role in posture-dependent dyspnea and

Microalbuminuria versus brain natriuretic peptide in cardiac hypertrophy of hypertensive rats.

Numai utilizatorii înregistrați pot traduce articole

The objective of this study was to assess a possible link between microalbuminuria (MA), a major risk factor of the cardiorenal syndrome and the brain natriuretic peptide (BNP), a marker of cardiac hypertrophy. Two kidney-one clip (2K-1C) renovascular hypertension was induced in 24 male Wistar rats

Collagen deposition and the reversal of coronary reserve in cardiac hypertrophy.

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to clarify how collagen deposition or medial hypertrophy of the vascular wall affects the coronary dilator reserve in pressure-overloaded hearts and whether inhibition of collagen deposition reverses the abnormalities after relief of pressure overload. We used ascending

Inhibitory effects of a subdepressor dose of L-158,809, an angiotensin II type 1 receptor antagonist, on cardiac hypertrophy and nephropathy via the activated human renin-angiotensin system in double transgenic mice with hypertension.

The effects of L-158,809, an angiotensin II type 1 receptor antagonist, on cardiac hypertrophy and nephropathy were examined using Tsukuba hypertensive mice (THM) carrying both human renin and angiotensinogen genes. Nine male THM aged 20 weeks were assigned to each of a no-dosage group and an

Significant role of the increase in renin-angiotensin system in cardiac hypertrophy and renal glomerular sclerosis in double transgenic tsukuba hypertensive mice carrying both human renin and angiotensinogen genes.

Numai utilizatorii înregistrați pot traduce articole

Tsukuba hypertensive mice (THM) are a hypertensive model prepared by mating a transgenic mice with human renin gene and a transgenic mice with human angiotensinogen gene. In the present study, we examined effects of renin-angiotensin system (RAS) on cardiac hypertrophy and renal disorders using

Urinary excretions of albumin and type IV collagen in normotensive and hypertensive subjects.

Numai utilizatorii înregistrați pot traduce articole

Plasma albumin leaks into urine as a result of glomerular hypertension and basement membrane injury, while urinary type IV collagen derives from mesangial matrix and glomerular basement membrane. The purpose of this study was to elucidate the pathophysiological significance of these urinary

Role of the renin-angiotensin system in cardiac hypertrophy and renal glomerular sclerosis in transgenic hypertensive mice carrying both human renin and angiotensinogen genes.

Numai utilizatorii înregistrați pot traduce articole

Tsukuba hypertensive mice (THMs) are transgenic mice carrying human renin and angiotensinogen genes. The aim of this study was to evaluate the role of the renin-angiotensin system (RAS) in cardiac hypertrophy and renal disorders in THMs. After a 2-wk control period, 10-wk-old THMs were treated with

Circulating soluble vascular cell adhesion molecule 1: relationships with residual renal function, cardiac hypertrophy, and outcome of peritoneal dialysis patients.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Vascular cell adhesion molecule 1 (VCAM-1) is involved in leukocyte-endothelial cell interaction and has a pivotal role in inflammation. Whether it contributes to excessive mortality in dialysis patients remains uncertain. In this study, we examined circulating soluble VCAM-1 (sVCAM-1) in

Determinants and prognostic importance of cardiomegaly among new ESRD patients in the United States.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Cardiomegaly is a radiographic abnormality of major prognostic importance in the general population. We explored the clinical correlations and mortality impact of cardiomegaly in new end-stage renal disease (ESRD) patients from the Dialysis Morbidity and Mortality Study Wave

Late referral to a nephrologist increases the risk of uremia-related cardiac hypertrophy in patients on hemodialysis.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The prognosis and outcome of patients with end-stage renal disease are related to the quality of predialysis care and the timing of referral. Late referral (LR) has been correlated with more frequent hospital admissions, malnutrition and cardiovascular mortality after hemodilaysis (HD) is

Cardiac hypertrophy, low blood pressure, and low aldosterone levels in mice devoid of the three circadian PAR bZip transcription factors DBP, HLF, and TEF.

Numai utilizatorii înregistrați pot traduce articole

The cardiovascular system is under the control of the circadian clock, and disturbed circadian rhythms can induce cardiovascular pathologies. This cyclic regulation is probably brought about by the circadian expression of genes encoding enzymes and regulators involved in cardiovascular functions. We

Increased C-reactive protein following hemodialysis predicts cardiac hypertrophy in chronic hemodialysis patients.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Chronic inflammation characterized by increased C-reactive protein (CRP) levels strongly predicts cardiovascular death in both nonrenal and renal patients. We investigated the role of hemodialysis-induced elevated CRP levels on cardiac hypertrophy in hemodialysis patients. METHODS We

Inflammation, residual kidney function, and cardiac hypertrophy are interrelated and combine adversely to enhance mortality and cardiovascular death risk of peritoneal dialysis patients.

Numai utilizatorii înregistrați pot traduce articole

C-reactive protein (CRP), the prototype marker of inflammation, and cardiac hypertrophy are important prognostic indicators in dialysis patients. Residual renal function (RRF) has also been shown to influence survival of peritoneal dialysis (PD) patients. This study examined the relations between

Patterns of regional ventilation in patients with cardiomegaly or left heart failure.

Numai utilizatorii înregistrați pot traduce articole

Patterns of regional ventilation have been examined in 42 patients, the majority of whom had clinical evidence of left-ventricular or left-atrial dysfunction. Regional ventilation was studied with xenon-133 and regional perfusion with Tc-99m human albumin microspheres. The presence of a cardiac

Arteriogenic therapy by intramyocardial sustained delivery of a novel growth factor combination prevents chronic heart failure.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Therapeutic angiogenesis is a promising approach for the treatment of cardiovascular diseases, including myocardial infarction and chronic heart failure. We aimed to improve proangiogenic therapies by identifying novel arteriogenic growth factor combinations, developing injectable
