ABSTRACT NUMBER: ESOC2026A1438 TRIPTAN EXPOSURE AFTER ISCHAEMIC STROKE OR MYOCARDIAL INFARCTION: A RETROSPECTIVE COHORT STUDY

Abstract Background and aims Triptans are a mainstay of acute migraine therapy but are contraindicated after ischaemic stroke (IS) or myocardial infarction (MI) because of presumed vasoconstrictive effects. However, evidence for increased vascular risk after triptan exposure in these populations is limited. We assessed whether triptan use after IS or MI is associated with recurrent vascular events in patients with migraine. Methods We conducted a retrospective cohort study using electronic health record data from the TriNetX US Network (2003–2022). Adult migraine patients with prior IS were included. Triptan exposure during years 1–2 after IS was compared with no triptan exposure, with outcomes assessed during years 3–5. Propensity score matching balanced baseline characteristics. Corresponding analyses were performed in migraine patients with prior MI and in comparator cohorts exposed to non-steroidal anti-inflammatory drugs (NSAIDs). Results The cohort comprised 49,388 migraine patients with IS not treated with triptans (mean age 54.0±14.7 years; 74.5% female) and 2,001 treated with triptans (mean age 51.4±13.3 years; 84.2% female). Annual rates of recurrent IS were 2.74% in triptan-treated patients versus 3.24% in controls (RR 0.85; 95% CI 0.68–1.05). Rates of MI (0.32% vs 0.33; RR 0.96) and all-cause mortality (0.58% vs 0.75; RR 0.77) were similar. Triptan use was associated with a significant increase in typical side effects, whereas NSAID exposure was associated with increased risks of recurrent IS and MI. Findings were consistent in MI cohorts. Conclusions In this large real-world cohort, triptan use after IS or MI was not associated with increased vascular risk.
