Key Points

This study investigates how exposure to cadmium, lead, and mercury affects long-term mortality in stroke survivors.
Cohort study design focusing on stroke survivors
Assessment of blood levels of cadmium, lead, and mercury
Evaluation of mortality outcomes and their association with heavy metal exposure
Elevated blood cadmium levels linked to increased all-cause mortality
Lead exposure shows a modest association with mortality
Mercury may have protective effects against some mortality outcomes

Abstract

Elevated blood cadmium levels are independently associated with increased all-cause mortality in stroke survivors. Lead shows a modest association with all-cause mortality, while mercury may exert protective effects against specific mortality outcomes. Further studies are needed to confirm these findings and explore underlying mechanisms.
