Correlating Noninvasive Cardiovascular Measures to Left Ventricular End Diastolic Pressure in Heart Failure
Correlating Noninvasive Cardiovascular Measures to Left Ventricular End Diastolic Pressure in Heart Failure
HF001 is a prospective observational study utilizing non-invasive medical devices that may be
 able to discriminate changes in heart failure while acutely decompensated patients undergo
 routine interventional therapies in a hospital setting. Subjects will be monitored using
 CVInsight™ [CVI] via a finger and/or forehead sensor, while performing an isometric handgrip
 stress test (IHGST). Changes in the CVI signal will be analyzed and correlated to standard
 assessments of heart failure including pulmonary artery catheter (PAC) pressures, blood
 pressure (BP), patient symptoms, and physical exam findings. The results of this study will
 be used to develop a powered study to determine if a new configuration of non-invasive
 monitoring devices can be used to monitor heart failure status more sensitively than current
 non-invasive techniques.
Inclusion Criteria:

 -  Adult patients ≥ 18 years old

 -  Signs and symptoms of congestive heart failure including two of the following:

 -  Peripheral edema (e.g. abdominal distension, hepatomegaly, lower extremity edema) in
 the setting of elevated jugular venous pressure as assessed by the clinical
 examination, or by right heart catheterization.

 -  Pulmonary edema or pleural effusion as seen on chest X-ray

 normal.
