Abstract:
In the context of global climate change, the impact of ambient temperature change on cardiovascular health has become increasingly significant. Epidemiological studies have shown that both high and low temperature can lead to the occurrence of adverse cardiovascular outcomes. For example, exposure to low temperature and high temperature, and diurnal temperature difference can increase the risk of cardiovascular diseases (CVD) mortality. Exposure to cold and heat, heatwaves and cold spells may induce myocardial infarction. Low temperature, high temperature and variations in temperature can increase the risk of heart failure. There are complex interactions among the effects of temperature and humidity, wind speed, radiation, precipitation and air pollution on adverse cardiovascular outcomes. Valnerable groups such as the elderly, patients with chronic diseases, and outdoor workers are particularly susceptible to temperature-related CVD risks. The mechanisms by which temperature affects adverse cardiovascular outcomes involves hemodynamic changes, autonomic nervous system dysregulation, blood rheology alterations, as well as inflammation and metabolic abnormalities, but many research gaps remain. Future studies should conduct in-depth research on mechanisms, individual differences, climate change impacts, and public health interventions to provide more effective policies and interventions to reduce the burden of CVD.
