Exposure to cadmium, lead, and mercury and long-term mortality after stroke: a cohort study

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
