Venous thromboembolism (VTE) carries a high risk of recurrence, making precise identification of high risk individuals crucial for optimizing anticoagulation strategies. This review summarizes current evidence on risk factors and prediction models for recurrent VTE. Recurrence is driven by a combination of baseline characteristics (e.g., male sex, non-O blood group), acquired clinical factors (e.g., initial proximal deep vein thrombosis or pulmonary embolism), and laboratory markers (e.g., D-dimer). Although multiple prediction models have been developed across diverse populations, they vary considerably in variable composition, target cohorts, and extent of external validation, and generally lack dynamic predictive capabilities. Future efforts should prioritize enhancing model generalizability, dynamic risk assessment, and clinical utility to guide individualized anticoagulation decisions and ultimately reduce recurrence rates.
