Vascular disease burden - 4 items
Cumulative vascular disease burden - Average of 4 items
This variable is only available in MAP, MARS, and LATC.
Vascular disease burden is computed using self-report questions for the following 4 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 4 and is the mean of the 4 individual scores multiplied by 4. 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 | 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 |
Congestive Heart Failure
| 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: This variable is available in MAP/MARS. ROS does not have CHF questions. Please use the 3-item version of this variable for analyses involving ROS.
