Filter by:The purpose of this study is to determine whether Warfarin Anticoagulation are effective and safe in Prevention of Portal Vein Thrombosis in Liver Cirrhotic Patients with Hypersplenism after Laparoscopic Splenectomy.
The goal of this study is to build a mathematical model to explain the effect of two doses of azilsartan (40 and 80 mg) upon metabolic (insulin resistance, glucose) and inflammatory parameters (cytokines) in function of "metabolic strata" like obesity, type 2 diabetes mellitus, hypertension and their combinations.
This study aims to investigate in adolescents and young adults: - the 24h diurnal variation of ambulatory central blood pressure - the association of central compared to peripheral blood pressure with indices of asymptomatic target-organ damage
The Registro Campania Salute Network (RCSN) is a prospective registry aimed at improving the management of essential hypertension by integrating the activity of general practitioners (GPs) with that of the hypertension specialist. It involves selected GPs homogeneously allocated in the regional area, and the Hypertension Clinic of the Federico II University in Naples, which served as co-ordinating centre. Through the RCSN system it is possible to store clinical data detected at each visit between the peripheral units and the co-ordinating centre and to support scientific analysis of the dataset.
Carotid baroreflex activation therapy (BAT) by the Rheos® system produces a sustained fall in blood pressure in patients with resistant hypertension. Since the activation electrodes are implanted at the level of the carotid sinus, it is conceivable that the nearby located carotid body chemoreceptors are stimulated as well. Physiological stimulation of carotid chemoreceptors not only raises respiration, but it also increases sympathetic activity which may in part counteract the effects of BAT. The aim of the present study is to investigate whether there is evidence for concomitant carotid chemoreflex activation during BAT. We hypothesized that there is no clinically relevant co-activation of the carotid body chemoreceptors during BAT in patients with resistant hypertension.
The aim of the study is to document the left and right ventricular function in patients with sclerodermia associated pulmonal arterial hypertension via 3D echocardiography. The results of this study should help to generate hypothesis for further future studies. The primary hypothesis is that the increased use of modern image guided methods could provide essential aspects for the follow up.
The purpose of this study is to evaluate the efficacy and safety of Candesartan/Amlodipine combined or alone and select better dose of CKD-330 in essential hypertension patients.
The aim of the study is to intensify the follow up of patients with pulmonary arterial hypertension via modern imaging guided methods in due consideration of the possibilities of three-dimensional echocardiography in order to optimize their specific therapy. The hypothesis is that the increased use of modern imaging guided tools is essential for the follow up.
Many patients with portal hypertension require surgical treatment each year,and Hassab's operation, or esophagogastric devascularization and splenectomy, is an elective procedure. In recent years,laparoscopic esophagogastric devascularization and splenectomy has been used to treat portal hypertension. However, the potential benefits remain to be demonstrated in the context of a randomized trial. In this study, 120 patients will randomize equally receiving laparoscopic or open esophagogastric devascularization and splenectomy. Inclusion criteria included: platelet count < 50×109/ml, esophageal and gastric varices revealed, agreeing the informed consent. PerioperativeOutcomes are: technical success, blood loose and infusion during the operation, recurrent varicose veins on gastroscopy examination, patterns of reflux on duplex ultrasound examination, complications, platelet and liver function variation, length of hospital stay. Follow-up will last 5 years, and gastroscopy and ultrasonic will perform at 3 months, 1 year, 3 years, and 5 years. Further more, this study was proved by the ethical committee of second hospital of Xi'an jiaotong university.
Left heart disease is the main cause of pulmonary hypertension. With the advent of the aging society, chronic heart failure has become a global public health problem. Therefore the prevalence of pulmonary hypertension due to the left heart disease is increasing. However, there is no research on the prevalence of pulmonary hypertension due to the left heart disease in China. Therefore, the aim of the present study was to describe real-world outcome of Chinese patients with pulmonary hypertension due to the left heart disease and identify factors that may predict outcome. Our study will profile the demographics, clinical course, treatments, and outcomes of pulmonary hypertension due to the left heart disease in China.
