Early DAPT associated with higher excellent functional outcome in minor stroke patients with history of DMEarly dual antiplatelet therapy may help stroke patients with diabetes

AI-generated summary of the cited source, checked by automated accuracy review. How we work

Key Takeaway
Note that early DAPT may be associated with better outcomes in minor stroke patients with a history of DM.

This secondary analysis evaluated 995 Chinese patients who experienced minor stroke and received intravenous thrombolysis. The study assessed the impact of early dual antiplatelet therapy (DAPT) compared to placebo on functional outcomes at 90 days.

In patients with a pre-existing history of diabetes mellitus (DM), early DAPT was associated with a higher rate of excellent functional outcome (modified Rankin Scale score 0-1) at 90 days, reported as 91.2% versus 81.7% in the placebo group (OR 2.76; 95% CI 1.22-6.22, p = 0.02). In contrast, no significant benefit was observed for patients with newly diagnosed DM (81.8% vs. 83.3%, OR 1.20, p = 0.83) or non-DM patients (89.6% vs. 92.5%, OR 0.70, p = 0.17).

Safety data and tolerability were not reported in the study. The results are considered preliminary and require further confirmation before clinical application. While a potential association exists for patients with a history of DM, the lack of significant interaction across subgroups (p = 0.09) suggests caution when interpreting these findings for broader stroke populations.

How this fits prior evidence

How this fits prior evidence: This finding addresses a gap in specific subgroup outcomes for minor stroke management following intravenous thrombolysis. While previous coverage noted that stroke etiology does not modify the efficacy of intravenous thrombolysis before endovascular treatment, this study explores how pre-existing comorbidities like diabetes mellitus may influence the impact of early dual antiplatelet therapy on functional outcomes.

Following a minor stroke, the road to recovery is often shaped by how quickly and effectively doctors can manage blood flow. A secondary analysis of a trial involving 995 Chinese patients looked at whether starting dual antiplatelet therapy (DAPT) early—combined with standard clot-busting medication—changed outcomes for those with diabetes.

The study found that patients who already had a history of diabetes saw a higher rate of excellent functional outcomes when they received early DAPT. Specifically, 91.2% of these patients achieved an excellent outcome compared to 81.7% in the group that did not receive it. However, this benefit was not seen in patients with newly diagnosed diabetes or those without diabetes at all.

While these results are promising for specific groups, experts note that this is a preliminary finding from a secondary analysis. Because the data comes from a specific population and requires further confirmation, it is not yet a definitive rule for all stroke patients. Patients should always discuss their specific treatment plan with their doctor.

What this means for you:
Early dual antiplatelet therapy may improve recovery outcomes specifically for stroke patients with a history of diabetes.

Common questions

Who specifically benefits from early dual antiplatelet therapy?

The study suggests that patients with a pre-existing history of diabetes may see the most benefit. In this group, 91.2% achieved an excellent functional outcome compared to 81.7% in the placebo group. The results were not significantly different for those with newly diagnosed diabetes or no diabetes.

What is an 'excellent functional outcome'?

In this study, an excellent functional outcome is defined as a modified Rankin Scale score of 0 to 1 at the 90-day mark. This indicates a high level of physical independence and recovery following the stroke.

Is this treatment proven for all types of stroke patients?

No, these are preliminary findings from a secondary analysis. While it showed promise for those with a history of diabetes, the results were not significant for other groups, and more research is needed to confirm these findings before they can be used as standard practice.

BACKGROUND: Early dual antiplatelet therapy (DAPT) after intravenous thrombolysis is safe but ineffective in improving 90-day functional outcomes in minor stroke. Given the effect of diabetes mellitus (DM) with antiplatelet treatment, we investigated whether DM status modifies the effect of early DAPT. METHOD: This secondary analysis of the Early Antiplatelet for Minor Stroke following Thrombolysis trial included patients from the modified intention-to-treat population. Participants were stratified by DM status (history of DM, newly diagnosed DM, non-DM). Outcomes were compared between early DAPT and placebo groups within each subgroup. The primary outcome was excellent functional outcome (modified Rankin Scale score 0-1) at 90 days. RESULTS: Among 995 analysed patients, early DAPT was associated with a significantly higher rate of excellent functional outcome in patients with a history of DM (91.2% vs. 81.7%; adjusted OR 2.76, 95% CI 1.22-6.22, p = 0.02). No significant benefit was observed in the newly diagnosed DM (81.8% vs. 83.3%; OR 1.20, 95% CI 0.24-5.95, p = 0.83) or non-DM subgroups (89.6% vs. 92.5%; OR 0.70, 95% CI 0.41-1.17, p = 0.17). The interaction across subgroups was not significant (p for interaction = 0.09). CONCLUSION: For Chinese patients with minor stroke receiving intravenous thrombolysis, early DAPT was potentially associated with a higher likelihood of excellent functional outcome at 90 days in those with a pre-existing history of DM. It warrants further confirmation. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05193071.
