Objectives: To investigate the risk of cerebrovascular accident (CVA) among patients with giant cell arteritis (GCA).
Methods: We conducted a systematic review and meta-analysis of cohort studies that reported relative risks, hazard ratios, or standardized incidence ratios comparing CVA risk in patients with GCA versus non-GCA comparators. Pooled risk ratio and 95% confidence interval were calculated using a random-effect, generic inverse variance method of DerSimonian and Laird.
Results: Eight studies with 17,919 patients with GCA were identified and included in our data analysis. The pooled risk ratio of CVA in patients with GCA versus non-GCA controls was 1.40 (95% CI: 1.27-1.56). The statistical heterogeneity was low with an I2 of 31%.
Conclusions: Our study indicates a significantly increased risk of CVA among patients with GCA.
