Vascular disease burden - 3 items
Cumulative vascular disease burden - Sum of 3 items
Vascular disease burden is computed using self-report questions for the following 3 items*:
Each item is given a value of 0 or 1 (see response options below). The cumulative score for vascular disease burden ranges from 0 to 3 and is the total number of items reported. Higher scores indicate greater vascular disease burden.
*In addition to self-report, evaluation of stroke is also based on neurological exam (when available), cognitive testing, and interview of participant, with which the physician may render a diagnosis of stroke.
Response values for each item:
Claudication
| Value | Coding |
|---|---|
| 1 | Reported pain in legs while walking which includes calves, in at least one cycle from baseline to this cycle |
| 0 | Never reported pain in legs or any reported pain that did not include the calves, from baseline to this cycle |
Stroke
| Value | Coding |
|---|---|
| 1 | Stroke present (Highly probable or probable stroke dx) reported in at least one cycle from baseline to this cycle |
| 0 | Stroke not present (Possible stroke dx or stroke not present), in all cycles, from baseline to this cycle |
Heart condition
| Value | Coding |
|---|---|
| 1 | Reported in past history or in at least 1 follow-up cycle up to this cycle |
| 0 | Never reported in past history or in follow-up cycle up to this cycle (includes suspect or possible) |
Note: The score is calculated if at least 2 out of 3 of the questions are answered.
A 4-item version of this variable includes CHF questions and is available for MAP, MARS, LATC. For ROS, the 4-item version is only available in recent years.
