This project is designed to assess the impact of non-invasive hemodynamic monitoring technologies to improve care of heart failure patients. Currently, these patients are assessed in the outpatient setting with no routine ability to assess hemodynamics related to contractility (dp/dt, stroke volume, cardiac output) or vascular resistance. Rather, the health care provider relies on their patient history, physical exam, and static vital signs (heart rate and blood pressure) to make their patient care decisions. This is despite the large body of evidence suggesting how poor these markers are at determining cardiac function and volume status. The investigators seek to "assist" the management of these high-risk patients by providing "routine" parameters of contractility and vascular resistance (via the ClearSight/Nexfin) system to the health care providers during the patients' clinic visits.
