Key result
A preoperative modified Rankin scale score of 2 to 4 was significantly associated with a higher rate of postoperative acute ischemic stroke compared to a score of 0 to 1 (28.5% vs 7.6%, p=0.02).
Why the study?
The study investigated the relationship between preoperative stroke history, vascular distribution areas, stroke-related factors, preoperative modified Rankin Scale scores, and postoperative outcomes in cardiac surgery patients.
Cohort (n=106)
No
Absolute Event Rate: 28.5% vs 7.6%
p-value: p=0.02
Higher preoperative modified Rankin scale (mRs) scores and chronic atrial fibrillation are significantly associated with an increased risk of postoperative acute ischemic stroke in patients with a history of stroke undergoing cardiac surgery.

May flag higher-risk cardiac surgery patients for monitoring; hypothesis-generating, needs prospective validation before practice change.
Işık et al. (2025) conducted a cohort in Prior stroke history in cardiac surgery (n=106). Preoperative modified Rankin scale (mRs) score ≥ 2 vs. Preoperative mRs score 0-1 was evaluated on Postoperative acute ischemic stroke (AIS) (p=0.02). A preoperative modified Rankin scale score of 2 to 4 was significantly associated with a higher rate of postoperative acute ischemic stroke compared to a score of 0 to 1 (28.5% vs 7.6%, p=0.02).
