Thromboelastography-Guided Antiplatelet Therapy for Patients with Ischemic Cerebrocardiovascular Diseases: A Systematic Review and Meta-Analysis.

Abstract

The effectiveness of thromboelastography (TEG)-guided antiplatelet therapy in patients with ischemic cerebrocardiovascular diseases is not well-established. This systematic review evaluates the efficacy and safety of TEG-guided antiplatelet therapy compared to standard treatment in patients with ischemic cerebrocardiovascular diseases. Randomized controlled trials (RCTs) and observational studies comparing TEG-guided antiplatelet therapy with standard therapy in patients suffering from ischemic stroke (IS) or coronary artery disease (CAD) were identified. The primary efficacy measure was a composite of ischemic and hemorrhagic events. Secondary efficacy measures included any ischemic events, while safety was assessed by the occurrence of bleeding events. Ten studies involving 4 RCTs and 6 observational studies with a total of 1,678 patients were included. When considering a composite of ischemic and hemorrhagic events in RCTs, a significant reduction was observed in IS or CAD patients under TEG-guided therapy compared to standard therapy (OR: 0.45, 95% CI: 0.27-0.75, p = 0.002). After pooling RCTs and observational studies together, compared to standard antiplatelet therapy, TEG-guided therapy significantly reduced the risk of a composite of ischemic and hemorrhagic events (OR: 0.26, 95% CI: 0.19-0.37; p < 0.00001), ischemic events (OR: 0.28, 95% CI: 0.19-0.41; p < 0.00001), and bleeding events (OR: 0.31, 95% CI: 0.16-0.62; p = 0.0009) in patients with IS or CAD. TEG-guided antiplatelet therapy appears to be both effective and safe for patients with IS or CAD. These findings support the use of TEG testing to tailor antiplatelet therapy in individuals with ischemic cerebrocardiovascular diseases.
