Background: Clopidogrel, prasugrel and ticagrelor, acting on platelet P2Y12 receptor, are commonly used for prevention of stent thrombosis (ST) among patients who underwent percutaneous coronary intervention (PCI). This study aimed to compare the effects of these drugs by a systematic review and network meta-analysis.
Hypothesis: Efficacies of clopidogrel, prasugrel and ticagrelor on preventing ST are not the same.
Methods: PubMed, Embase and Cochrane Library were searched for randomized controlled trials (RCTs) that investigated the effect of clopidogrel, prasugrel, or ticagrelor on prevention of ST in patients who underwent PCI. The efficacies between groups were compared by a Bayesian network meta-analysis, by which the pooled odds ratios (ORs) and 95% confidence intervals (CIs) was calculated.
Results: Fourteen studies and 46 983 participants were included in this study. The pooled results illustrated that clopidogrel, prasugrel and ticagrelor were effective on prevention of ST. Patients treated with prasugrel (OR = 0.30, 95% CI = 0.052 ~ 0.73, P < 0.05) and ticagrelor (OR = 0.25, 95% CI = 0.035 ~ 0.65, P < 0.05) had lower incidence of ST compared to those treated with clopidogrel. Patients treated with ticagrelor showed similar frequency with those in prasugrel group (OR = 0.86, 95% CI = 0.22 ~ 2.3, P > 0.05). No significant heterogeneity was observed across included studies.
Conclusions: Our findings suggest that prasugrel and ticagrelor are more effective than clopidogrel on prevention of ST among patients underwent PCI. Simultaneously, there is no significant difference in the prevention of ST between prasugrel and ticagrelor.

Intracranial hemorrhages are highly concerning but underreported complications related to flow diversion (FD) treatment of intracranial aneurysms. Herein, we aimed to characterize these complications and the factors influencing their occurrence. We retrospectively reviewed patients treated with FD from 2013 to 2023 at a single U.

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within 30 minutes before the end of infusion in the case of a LD of prasugrel.

Flow diversion is a transformative approach in neurointerventional surgery for intracranial aneurysms that relies heavily on effective antiplatelet therapy. The ideal approach, including the timing of treatment, the use of dual antiplatelet therapy (DAPT), and the number of flow-diverter devices to use, remains unknown. DAPT, which combines aspirin with a thienopyridine like clopidogrel, prasugrel, or ticagrelor, is the standard regimen, balancing thromboembolic protection and hemorrhagic risk.

Background: Advances in secondary stroke prevention, including direct oral anticoagulants (DOACs), dual antiplatelet therapies (DAPT), and cardiovascular risk management, have changed costs over the past decade. This study aimed to evaluate annual treatment costs and trends in drug-based secondary prophylaxis after ischemic strokes.
Methods: Annual treatment costs were evaluated using the net costs per defined daily dosage (DDD) of discharge medications for ischemic stroke patients treated in 2020 at the University Hospital Frankfurt, Germany.
Background: Antiplatelet drugs, such as clopidogrel, ticagrelor, prasugrel, and acetylsalicylic acid, may be associated with a risk of adverse events (AEs). Vanessa's Law was enacted to strengthen regulations to protect Canadians from drug-related side effects (with mandatory reporting of serious adverse events [SAEs]).
Objective: To determine whether Vanessa's Law has led to an increase in SAE reporting among antiplatelet users.
