Filter by:The purpose of this study is to evaluate the effects of oral azilsartan once daily for 32 weeks on coronary artery plaque in essential hypertensive patients with stable angina and dyslipidemia.
Sepsis is the most common cause of childhood death worldwide. Millions of children survive, but are left with impaired health. Sepsis-related Acute Kidney Injury (sAKI) is increasingly recognized as a significant factor associated with long-term mortality among different patient populations. Renal dysfunction and subsequent chronic kidney disease is implicated in the development of hypertension and cardiovascular disease. The investigators overall hypothesis is that, in the pediatric population, sepsis-related AKI will have unrecognized, long-term consequences with regard to kidney function, endothelial function, blood pressure control, and overall health.
The purpose of the study is to test the hypothesis that persistent fluid retention and high sympathetic output contributes to the development of refractory hypertension (HTN). The investigators will determine, in a cross-over assessment of high and low salt diets, if dietary sodium restriction reduces 24-hr ambulatory BP in patients with refractory HTN. Moreover, the investigators will determine if dietary sodium restriction lessens the severity of obstructive sleep apnea (OSA) in patients with refractory HTN.
Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package- the Transthoracic Parametric Doppler (TPD) (Echosense Ltd., Haifa, Israel). Systemic sclerosis patients often develop pulmonary vascular disease leading to pulmonary hypertension. The TPD system may provide important insight into pulmonary blood vessels characteristics by the LDS (Lung Doppler Signals) signals that are related to pulmonary hypertension. The TPD performance in detecting PAH in SSc patients will be assessed in the study.
The objective of the study is to monitor physical activity longitudinally with a wrist activity tracker specifically in PAH patients newly initiating ERA therapy and to assess the correlation with the 6MWD at different time points. Further objectives are to assess the correlation of physical activity measured with the tracker and other parameters for clinical evaluation and right ventricular function assessment (i.e. Biomarkers, WHO Functional class, hospitalization due to PAH, Echochardiography and Quality of Life) as well as sleep efficacy in PAH patients newly initiating ERA therapy.

The proposed study is a physiologic investigation of the effects of testosterone on the natriuretic peptide system. The hypotheses of the study are that testosterone administration will decrease natriuretic peptide levels and salt excretion. The entire protocol is 8 weeks in duration.
The objective of this study is to assess if prolonged storage time of a packed red blood cell unit may cause pulmonary vasoconstriction after transfusion, in a susceptible population such as cardiac surgery patients. The investigators will also evaluate the potential reversal effect of Inhaled Nitric Oxide on pulmonary vasoconstriction induced by stored blood transfusions.
China Rural Hypertension Control (CRHC) Project is a cluster randomized trial aims to test the effectiveness of a standardized protocol-based treatment program on hypertension control in rural China.
The purpose of this study is to assess the predictive performance of the pulmonary vascular reactivity to acetylcholine, in the presence pulmonary arterial hypertension (estimated 1 year after the closure of the shunt).
