Smokers with Elevated Glycated Albumin Could Not Benefit from Dual Antiplatelet Therapy after Minor Stroke or Transient Ischemic Attack

Introduction: The aim of this study was to investigate the impact of smoking on dual antiplatelet therapy in patients with minor stroke or transient ischemic attack (TIA) under different glycated albumin (GA) levels. Methods: We analyzed data from the Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial. A subgroup of 3,044 patients with baseline GA levels was included and categorized by smoking status and GA levels. The primary efficacy outcome was a new stroke within 90 days. The safety outcome was any bleeding event at 90 days. The interaction of smoking status with antiplatelet therapy was calculated by Cox proportional hazards regression model. Results: In patients with GA levels ≤15.5%, the proportion of smokers was 37.7% (719/1,908), while in patients with GA levels >15.5%, it was 51.6% (586/1,136). During the 3-month follow-up period, 299 (9.9%) patients had a new stroke occurrence. In patients with elevated GA levels, both smokers and nonsmokers could not benefit from dual antiplatelet therapy (smokers, adjusted hazard ratio [HR] 0.70, 95% confidence interval [CI]: 0.42–1.17; nonsmokers, adjusted HR 0.82, 95% CI: 0.57–1.18). In patients with normal GA levels, dual antiplatelet therapy reduced the risk of stroke recurrence in smokers by 72% (adjusted HR 0.28, 95% CI: 0.14–0.56) and in nonsmokers by 53% (adjusted HR 0.47, 95% CI: 0.26–0.86). However, whether the GA level was elevated or normal, there was no significant interaction between smoking status and antiplatelet therapy. Conclusions: Smokers with elevated GA levels could not benefit from dual antiplatelet therapy after minor stroke or TIA.
