What this trial studies

This study aims to validate a prediction model for assessing the severity and prognosis of acute pulmonary embolism (PE) using multi-center data. It involves enrolling patients aged 18 and older who have been diagnosed with acute PE through various imaging techniques. The study collects comprehensive demographic, clinical, and imaging data, and follows patients over time to evaluate survival outcomes. The model will be optimized using artificial intelligence clustering algorithms to enhance its predictive capabilities.

Who should consider this trial

Good fit: Ideal candidates for this study are inpatients aged 18 years or older diagnosed with acute pulmonary embolism.

Not a fit: Patients who are unable to complete follow-up due to cognitive or behavioral limitations may not benefit from this study.

Why it matters

Potential benefit: If successful, this model could significantly improve the prognosis and management of patients with acute pulmonary embolism.

How similar studies have performed: While this approach is based on existing data, the use of artificial intelligence for model optimization in this context is relatively novel.
