CVORRES: Result of the measurement or finding as originally received or collected.
CVORRESU: Original units in which the data were collected. Unit for CVORRES.
CVSTRESC: Result value for all findings from CVORRES in a standard format or in standard units. If results are numeric, they should also be stored in numeric format in CVSTRESN.
CVSTRESN: Used for continuous or numeric results or findings in standard format; copied in numeric format from CVSTRESC.
CVSTRESU: Standardized units used for CVSTRESC and CVSTRESN.
CVLOBXFL: Last Observation Before Exposure Flag. Operationally-derived indicator used to identify the last non-missing value prior to RFXSTDTC. The value should be "Y" or null.

Global longitudinal strain (GLS) and global circumferential strain (GCS) are used in cardiac magnetic resonance (CMR) to assess and track cardiac function. SMEs- add text
Example
This example shows the representation of circumferential and longitudinal strain findings in the CV domain. The sponsor used the "CMRBRANDTYP Feature Tracking" analysis method (CVANMETH).
Rows 1-3:
Show circumferential strain for the left ventricle base, mid, and apex regions.
Row 4:
Shows circumferential strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT.
Row 5:
Shows global circumferential strain.
Rows 6-8:
Show longitudinal strain for 4 chamber, 3 chamber, and 2 chamber views.
Row 9:
Shows longitudinal strain for the LEFT VENTRICULAR BASAL INFEROSEPTAL SEGMENT.
