Comorbidity and risk of venous thromboembolism after hospitalization for first-time myocardial infarction: A population-based cohort study.

Thirty-day VTE risk was substantially increased after MI compared with the general population. Although the absolute VTE risk was low, comorbidity substantially increased this risk, especially hemiplegia and cancer. VTE prophylaxis might be indicated in such high-risk patients but warrants further investigation.
