The Nanowear Wearable System SimpleSense Validation Trial for Cardiac Output

The Nanowear SimpleSense study is a single center, prospective, non-randomized, feasibility, non- significant risk study The study will be done in 2 phases. Phase 1 will use SimpleSense data collected from the first set of subjects and associate the data from SimpleSense to the right heart catheterization values.' Phase 2 will evaluate the algorithms developed to estimate cardiac output from SimpleSense data using a second set of subjects from within the sample population that are sequestered from the first set used for association of data from SimpleSense to the data from the right heart catheterization.

China Pulmonary Vascular Disease Intervention Diagnosis and Management Study-right Heart Catheterization

Right heart catheterization(RHC) plays a crucial role in the diagnosis and treatment of pulmonary vascular diseases(PVD). In China, the lack of equipment and technical expertise has historically limited the implementation of RHC, thereby greatly restricting the diagnosis and treatment of RVD. In recent years, with improvements in these issues, more hospitals have acquired the capability to perform RHC. The purpose of this study is to conduct quality control of RHC across multiple pulmonary hypertension(PH) centers in China. The study population consists of patients who underwent RHC for the first time due to dyspnea or suspected PH. This study retrospectively and prospectively collects multicenter RHC data, with the main quality control contents including indications for the procedure, collection and analysis of hemodynamic data, diagnosis and treatment, and long-term management of patients.
