The reduction of venous thromboembolism (VTE) is only partially related to low-density lipoprotein cholesterol (LDL-C) reduction while the benefit was larger than that observed for atherothrombotic risk, a recent study found. The meta-analysis of randomized controlled trials with statin treatment compared a statin with either placebo or another statin treatment and included ≥100 adult participants while lasting at least 24 weeks. Researchers found:
- 30 RTCs and 159,058 participants (1,431 events) were included, with 28 reporting LDL-C data.
- Network meta-analysis indicated a larger benefit for rosuvastatin compared to placebo and other statins.
- The risk reduction in VTE was proportional to LDL-C decrease (37% relative lower risk per each 1 mmol/L reduction in LDL-C).
- A reduction of 1 mmol/L in LDL-C translates in 37 fewer VTE events per year in 100,000 people, corresponding to 3,162 prevented episodes per year in those aged 50-59 years.
