Number of Participants With NIHSS Scores
Time Frame: Pre-procedure and at discharge (Up to 405 Days)
|
The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS) is a tool used to objectively quantify the impairment caused by a stroke.
The NIHSS is composed of 11 items, each of which scores a specific ability between 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment.
The individual scores from each item are summed to calculate a patient's total NIHSS score.
The patient's total NIHSS score ranges from 0 (minimum) - 42 (maximum).
Score 0 (no stroke symptoms); 1 - 4 (Minor stroke); 5-15 (Moderate stroke); 16-20 (Moderate to severe stroke); and 21-42 (Severe stroke).

Montreal Cognitive Assessment (MoCA) is used for detecting cognitive impairment, the scores range from 0 to 30.
A score of 26 or higher is considered normal, patients with mild cognitive impairment (MCI) were scored an average of 22 and patients with significant cognitive impairment (SCI) were scored an average of 16.

Hospitalization included cardiovascular events due to any cause post index procedure, regardless of protocol-defined serious/non-serious adverse events (AEs) or not.
Hence this data was not contributed in serious Adverse events until met the AE definition.
