Filter by:Right ventricular (RV) failure is the leading cause of death in pulmonary arterial hypertension. (PAH) Right ventricular ejection fraction is one of the most important predictors of prognosis in heart failure patients regardless of cause. It is estimated that 30-50% of patients with heart failure and preserved ejection fraction (HFpEF) have right ventricular dysfunction and up to 70% of these patients will have significant pulmonary hypertension (PH), both of which are related to much worse prognosis. Right ventricular failure is becoming an increasingly prevalent and significant cause of morbidity in patients with left heart disease. Despite the significance of RV function to survival, there are no therapies available that directly or selectively improve RV function. The overall theme of this research project is to evaluate the mechanisms that contribute to the cause of right heart failure. This small study is designed to look at the role of heart and lung metabolism and pulmonary hypertension as they relate to the development of right heart failure in cardiovascular disease.(PH-LHD)
The purpose of this study is to test whether abatacept, a drug approved by the Food and Drug Administration to treat rheumatoid arthritis, may help blood pressure medications to work better. This will be studied in people with high blood pressure that is not well controlled on three or more blood pressure medications, the condition also known as resistant hypertension. We expect to show that adding abatacept therapy to standardized treatment of resistant hypertension will result in a greater decrease in blood pressure at 24 weeks compared to treatment with placebo and conventional blood pressure treatment.
The primary purpose of this study is to investigate the safety and efficacy of bilateral DWT in subjects with POAG or OHT compared to active and sham controls. The secondary purpose of the study is to investigate the durability, repeatability, and does response of the same.
Study to assess the safety of terbogrel during open-label, long-term treatment in medically stable or improving patients with primary pulmonary hypertension who have completed the 12-week, double-blind randomized trial of terbogrel (protocol 528.19)
The purpose of this study is to see if Regadenoson may offer improved ease of use, single dose administration, and better tolerance for testing for pulmonary hypertension than iNO. You will be screened to make sure Regadenoson is safe for you with a clinical evaluation, blood tests, and an ECG.
In patients with type 2 diabetes, the effects on blood pressure of vitamin D has been shown to be variable. Thus, the goal of this proposal is to evaluate the effect of vitamin D supplementation in patients with type 2 diabetes and hypertension
Acute secondary pulmonary hypertension (PH) often leads to dysfunction of the right ventricle (RV) and can be a significant cause of patient morbidity and mortality. Selective pulmonary vasodilation with inhaled nitric oxide (INO) has become the treatment of choice for this condition. The evidence supporting INO safety and efficacy under these circumstances is sparse, however, and is largely extrapolated from the use of INO in neonatal pulmonary hypertension. Moreover, the high cost and potential toxicity of INO makes the therapy far from ideal. Emerging evidence suggests that inhaled aerosolized prostacyclins such as iloprost may be a favorable alternative therapy.
This research study is looking at the use of the drug ambrisentan and if it can improve right ventricle function in people with systemic sclerosis-associated pre-pulmonary arterial hypertension. It is also looking at using right ventricle function changes as a marker of disease severity.
To evaluate the efficacy and safety of 26-weeks of treatment with riociguat vs. placebo in patients with symptomatic PH (pulmonary hypertension) associated with IIP (idiopathic interstitial pneumonias).
This study was a prospective, randomized trial designed to investigate the efficacy of moderate lifestyle modification for improving the clinical status of patients with coronary artery disease or patients with risk factors that promote coronary artery disease.
