Air pollution and venous thromboembolism: current knowledge and future perspectives.

Area of Science:

• Environmental Health
• Epidemiology
• Cardiovascular Research

Background:

• Air pollution, a mix of gases and particulate matter, is a significant global health issue.
• Particulate matter is a leading cause of harm, with over 90% of the global population exposed to excessive levels.
• Existing evidence links air pollution to cardiovascular disease, but its association with venous thromboembolism is less clear.

Purpose of the Study:

• To review the current epidemiological evidence connecting air pollution and venous thrombotic events.
• To explore the biological mechanisms underlying the link between air pollution and thrombosis.
• To discuss potential strategies for mitigating the health impacts of air pollution.

Main Methods:

• Review of epidemiological studies on air pollution and venous thromboembolism.
• Examination of proposed pathophysiological mechanisms.
• Discussion of global health strategies.

Main Results:

• A growing body of evidence suggests a link between particulate matter exposure and venous thromboembolism.
• Mechanisms include platelet dysfunction, impaired fibrinolysis, and increased thrombin generation, contributing to a thromboinflammatory state.
• Cardiovascular disease accounts for a substantial proportion of air pollution-related deaths.

Conclusions:

• Air pollution poses a serious threat to global health, with increasing evidence linking it to venous thromboembolism.
• Understanding the mechanisms is crucial for developing effective public health interventions.
• Mitigation strategies are needed worldwide to reduce the health burden of air pollution.
