[0002] When miners work underground, they are exposed to a large amount of harmful gases and dust, high-intensity noise pollution, and high temperature and humidity in the mines, which will increase the burden on their cardiovascular and cerebrovascular systems and increase the risk of cardiovascular and cerebrovascular diseases. Therefore, miners need to undergo regular risk assessments of cardiovascular and cerebrovascular diseases.
