Momentum-3 is the name of an investigational device exemption (IDE) clinical study that was designed to evaluate the effectiveness and safety of the HeartMate 3 Left Ventricular Assist System (LVAS) by demonstrating non-inferiority to the HeartMate 2 LVAS when used for treatment of advanced refractory left ventricular heart failure (HF).

The Glasgow Coma Scale (GCS) is a scoring scale used by clinicians to assess and describe the level of consciousness in an individual following a traumatic brain injury. The scale measures three clinical signs: eye opening, verbal response and motor response. Eye opening is scored from 1 - 4, verbal response is scored from 1 - 5 and motor response is scored from 1 - 6. The values assigned for each clinical sign category are based off standardized criteria. The values are then added together to create a total composite score ranging from 3 - 15. The degree or severity of brain injury is further classified using the total GCS score into three categories: Severe = GCS 8 or less Moderate = GCS 9 - 12 Mild = GCS 13 - 15 What type of data would the total GCS score and the severity of brain injury classification be, respectively?
