NCT02244957
The coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in the same patient has been termed overlap syndrome, affecting 1% of the U.S. population.The investigators propose to conduct this study that aims: (1) to compare right and left ventricular hemodynamic parameters using cardiac magnetic resonance imaging (MRI) in overlap syndrome vs. COPD only and OSA only; (2) to compare the effects of bi-level positive airway pressure (BPAP) vs. nocturnal oxygen therapy (NOT) on right ventricular (RV) hemodynamics in overlap syndrome. This study will allow us to test the hypothesis: (1) Patients with overlap syndrome have more RV dysfunction than those with COPD only or OSA only; (2) treatment of both hypoxemia and hypercapnia during sleep will improve RV hemodynamics compared with treatment of hypoxemia alone in patients with overlap syndrome.
NCT02511158
In this study we will examine patients who have undergone anterior cruciate and/or posterior cruciate ligament and/or multi ligaments reconstruction to determine the rate of re-injury, contralateral tear and functional outcomes at least two years after surgery.
NCT03357731
The purpose of this study is to evaluate the effects of BMS-986231 on systolic and diastolic parameters in patients with heart failure and low ejection fraction.
