Intensive Versus Standard Systolic Blood Pressure Targets Following Successful Endovascular Thrombectomy for Acute Ischemic Stroke: A Systematic Review With Frequentist and Bayesian Meta-Analysis
BACKGROUND: Blood pressure management following successful reperfusion with endovascular thrombectomy for acute ischemic stroke due to large vessel occlusion remains debated. This meta-analysis aimed to determine whether intensive systolic blood pressure (SBP) management improves clinical outcomes compared with a standard approach after endovascular thrombectomy. METHODS: We systematically searched PubMed, Scopus, Embase, and Web of Science through October 2025 for relevant randomized controlled trials comparing intensive (SBP target <140 mm Hg) versus standard (SBP target <180 mm Hg) management. The primary efficacy and safety outcomes were functional independence (modified Rankin Scale score, 0–2) and any intracranial hemorrhage, respectively. We performed frequentist and Bayesian random-effects meta-analyses, supplemented by trial sequential analysis. RESULTS: Six randomized controlled trials comprising 1972 patients were included. In frequentist analysis, intensive SBP management was associated with a significantly reduced likelihood of achieving functional independence (risk ratio, 0.83 [95% CI, 0.73–0.93]). Bayesian analysis confirmed this harmful effect (posterior median risk ratio, 0.83 [95% credible interval, 0.7–1.02]), with a posterior probability of benefit of only 3.2%. Furthermore, ordinal shift analysis indicated that intensive SBP management was associated with a significant shift toward worse functional outcomes across the full modified Rankin Scale score distribution (common odds ratio, 1.26 [95% CI, 1.10–1.44]), a finding supported by a low posterior probability of benefit of 2.1%. No significant differences were observed in the risk of any intracranial hemorrhage (risk ratio, 1.05 [95% CI, 0.96–1.16]). The corresponding Bayesian analysis yielded a posterior risk ratio estimate of 1.05 (95% credible interval, 0.90–1.21) for any intracranial hemorrhage, with a posterior probability of benefit of 23%. Trial sequential analysis indicated that the cumulative evidence reached the boundary for harm and futility for the primary efficacy and safety outcomes, respectively. CONCLUSIONS: In patients with acute ischemic stroke following successful endovascular thrombectomy, intensive SBP management was associated with worse functional outcomes and provided no clear safety benefit. These findings support a standard, guideline-based SBP management strategy over an intensive approach.
Catheter Ablation for Ventricular Tachycardia in Ischemic Cardiomyopathy: A Meta‐Analysis With Reconstructed Time‐to‐Event and Trial Sequential Analysis
ABSTRACT Background Ventricular tachycardia (VT) is a major contributor to sudden cardiac death among patients with ischemic heart disease (IHD). While catheter ablation reduces the arrhythmic burden, the impact on long‐term outcomes remains uncertain. We assess the efficacy of catheter ablation in patients with IHD. Methods We performed a meta‐analysis by systematically searching electronic databases from inception to April 2025. Pairwise, reconstructed time‐to‐event data meta‐analyses and Trial Sequential analyses were conducted. Results A total of seven studies (1192 participants) were included. Among patients with IHD with ICD, VT ablation was associated with a significant reduction in ICD shocks (RR = 0.50, 95% CI = [0.34–0.74]), a trend toward reduced VT storm (RR = 0.64, 95% CI = [0.40–1.04], p = 0.07), and lower rates of cardiovascular hospitalization (RR = 0.73, 95% CI = [0.53–1.01], p = 0.06) compared to ICD alone. However, no significant differences were observed when compared to patients receiving ICD plus antiarrhythmic drugs (AADs). VT ablation showed no significant impact on mortality or VT/VF recurrence compared to either ICD alone or ICD with AADs. Reconstructed Kaplan–Meier analysis for all‐cause mortality showed no significant difference between VT ablation and AAD + ICD. Trial Sequential Analysis provided conclusive evidence for VT/VF recurrence, while further data is required for other outcomes. Conclusion Among patients with IHD with ICD, VT ablation reduces ICD shocks, VT storm, and cardiovascular hospitalizations compared to ICD‐only therapy, but offers no significant advantage over ICD combined with AADs. VT ablation does not impact overall mortality or the recurrence of VT/VF. Trial sequential analysis confirmed conclusive evidence for VT/VF recurrence, while additional data is needed for other outcomes.
Impact of Anemia on Clinical Outcomes in Atrial Fibrillation Patients on Oral Anticoagulants: A Prognostic Meta‐Analysis
ABSTRACTBackgroundAnemia is frequently observed as a comorbidity in atrial fibrillation (AF), especially in elderly patients and in those on anticoagulation. This has been associated with poor clinical outcomes. We aim to investigate the impact of anemia on clinical outcomes in patients with AF on oral anticoagulation.MethodsWe comprehensively searched PubMed, WOS, SCOPUS, EMBASE, and CENTRAL through March 2024 and conducted a prognostic systematic review and meta‐analysis. All analyses were performed using R V. 4.3.1. This meta‐analysis was registered at PROSPERO (CRD42024556023).ResultsWe included 23 studies comprising 286,781 patients for analysis. Anemia had a significant association with an 84% increase in risk of major bleeding (HR: 1.84 with 95% CI [1.59, 2.13], p < 0.01), a 32% increase in the risk of intracranial hemorrhage (HR: 1.32 with 95% CI [1.10, 1.58], p < 0.01), a 98% increase in the risk of gastrointestinal bleeding (HR: 1.98 with 95% CI [1.67, 2.35], p < 0.01), and a 91% increase in the risk of all‐cause mortality (HR: 1.91 with 95% CI [1.46, 2.51], p < 0.01). However, the impact of anemia did not significantly affect the risk of stroke, transient ischemic stroke (TIA), or systemic embolism (HR: 1.07 with 95% CI [0.93, 1.22], p = 0.36).ConclusionAnemia was significantly associated with an increased risk of major bleeding, intracranial hemorrhage, gastrointestinal bleeding, and all‐cause mortality. However, anemia did not significantly impact stroke, TIA, or systemic embolism.
