Abstract
AIM
A previous randomized study showed that dual antiplatelet therapy (DAPT) with aspirin and cilostazol is not superior to aspirin monotherapy for patients with acute non-cardioembolic stroke; however, the reason for this remains uncertain. We focused on the unusual side effects of cilostazol, namely, tachycardia changes, and validated their influence on patients with acute non-cardioembolic stroke.
METHODS
This post-hoc study extracted data from the acute aspirin plus cilostazol dual therapy study (ADS) registry, a multicenter, prospective, randomized, open-label trial. Patients were randomly allocated to the dual group (aspirin plus cilostazol) and the aspirin monotherapy group (aspirin alone). Tachycardia changes were defined as ≥ 5% heart rate increase at 48 h after admission compared with that at admission. Baseline data and outcomes were validated with four divided groups: aspirin-non-tachycardia changes (AN), aspirin-tachycardia changes (AT), dual-non-tachycardia changes (DN), and dual-tachycardia changes (DT).
RESULTS
Finally, 1,188 patients were analyzed in this ADS post-hoc analysis (aspirin monotherapy group, 594; dual group, 594). The proportion of change in tachycardia was 19.2% in the aspirin monotherapy group and 38.2% in the dual group (p<0.001***). Although the recurrences of symptomatic stroke and transient ischemic attack were not significantly different, the neurological deterioration was significantly different among the AN, AT, DN, and DT groups (p<0.05*).
CONCLUSIONS
Tachycardia changes increase neurological deterioration even in patients with non-cardioembolic acute stroke. DAPT consisting of aspirin and cilostazol increases the proportion of tachycardia changes and is not superior to aspirin monotherapy.
