Microgravity-induced alterations in left atrial hemodynamics and thrombogenic risk: Insights from healthy and atrial fibrillation models

Key Points

• Altered left atrial hemodynamics increases thrombogenic risk under microgravity conditions, impacting cardiovascular health.
• In atrial fibrillation models, microgravity significantly elevates the thrombogenic risk, indicating potential adverse effects.
• Microgravity exposure leads to noticeable changes in cardiac hemodynamics, specifically within the left atrial structure.
• Understanding these alterations emphasizes the need for assessing cardiovascular risks in astronauts, given recent space exploration plans.
