Objectives High on‐treatment platelet reactivity (HTPR) determined by platelet function assays is present in certain patients with ischemic stroke or transient ischemic attack (TIA)。 However， it is unclear whether HTPR is associated with poor clinical outcomes。 Our study aimed to investigate the relationship of HTPR with recurrent vascular events in ischemic stroke or TIA。 Methods Pubmed (MEDLINE)， EMBASE， and Cochrane Library were searched for eligible studies from inception to January 1， 2022。 Stata 17。0 software was used to calculate the risk ratio (RR)。 Subgroup and sensitivity analyses were conducted to assess the source of heterogeneity。 A random‐effects model was used when heterogeneity was present。 Primary endpoint of the meta‐analysis was the risk ratio of recurrent vascular events in HTPR Patients。 While stroke and TIA， all‐cause death， early neurological deterioration， early new ischemic lesions， and stroke severity measured by National Institute of Health Stroke Scale (NIHSS) scores at admission were also pooled。 Results Thirty articles (7995 patients) were eligible including 28 cohort studies and 2 prospective case–control studies。 The prevalence of HTPR varied from 5。9% to 60%。 HTPR was associated with an increased risk of recurrent vascular events (RR?=?2。94， 95% CI 2。04–4。23)， stroke recurrence (RR?=?2。05; 95% CI 1。43–2。95)， and all‐cause mortality (RR?=?2。43; 95% CI 1。83–3。22)。 Subgroup analysis showed that HTPR determined by optical aggregometry， Verify‐Now system and 11dh TXB2 is related to a higher risk of recurrent vascular events (RR?=?3。53， 95% CI 1。51–9。40; RR?=?2。16， 95% CI 1。02–4。56; RR?=?3。76， 95% CI 1。51–9。40， respectively)。 Moreover， patients with HTPR had an increased incidence of early neurological deterioration (RR?=?2。75; 95% CI 1。76–4。30) and higher NIHSS scores at admission (Mean difference 0。19， 95% CI 0。01–0。36)。 Conclusions This meta‐analysis demonstrates HTPR is associated with higher risk of recurrent vascular events， early neurological deterioration and increased severity in patients with ischemic stroke and TIA。 HTPR measured by platelet function assays may guide the use of antiplatelet agents in ischemic stroke and TIA。
