Vascular disease burden - 3 items
Cumulative vascular disease burden - Average 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 mean of the 3 individual scores multiplied by 3. Higher scores indicate greater vascular disease burden. The score for vascular disease burden is calculated if at least 2/3 of the questions are answered.
*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 | Response |
|---|---|
| 0 | Never reported pain in legs or any reported pain that did not include the calves, from baseline to this cycle |
| 1 | Reported pain in legs while walking which includes calves, in at least one cycle from baseline to this cycle |
Stroke
| Value | Response |
|---|---|
| 0 | Stroke not present (Possible stroke dx or stroke not present), in all cycles, from baseline to this cycle |
| 1 | Stroke present (Highly probable or probable stroke dx) reported in at least one cycle from baseline to this cycle |
Heart condition
| Value | Response |
|---|---|
| 0 | Never reported in past history or in follow-up cycle up to this cycle (includes suspect or possible) |
| 1 | Reported in past history or in at least 1 follow-up cycle up to this cycle |
Note: A 4-item version of this variable includes CHF questions and is available for MAP/MARS only.
