New Study Reveals Increased Risk of Heart Attacks During Heat Waves and Fine Particulate Pollution
According to a new study published in Circulation, certain groups of people have twice the risk of dying from a heart attack during heat waves and high levels of fine particulate pollution. The study, which analyzed over 202,000 heart attacks that occurred in the Chinese province of Jiangsu between 2015 and 2020, found that extreme heat, extreme cold, or high levels of fine particulate matter air pollution were linked to a higher risk of death from cardiac events.
The researchers discovered that the risk was particularly high during four-day heat waves with fine particulate pollution above 37.5 micrograms per cubic meter. Women and older adults were identified as being the most vulnerable, with the average age of death among adults who died from heart attacks being 77.6. These findings suggest that extreme temperature events and fine particulate pollution can interact to trigger a greater risk of death from heart attacks.
A cardiologist who was not involved in the research explained that exposure to extreme heat and pollution puts stress on the cardiovascular system, increasing the risk of heart attacks and heart issues. To help prevent the risk of death from heart attacks, the study’s researchers recommended reducing exposure to extreme temperatures and fine particulate pollution.
The study’s recommended strategies include following weather forecasts, staying indoors during extreme temperatures, using fans and air conditioners, dressing appropriately, staying hydrated, and reducing exposure to air pollution. Additionally, individuals with a history of heart disease or cardiovascular problems should be cautious and take shorter walks outside during extreme heat conditions. It is also important for them to stay hydrated to avoid dehydration.
Furthermore, people taking cardiovascular medications or suffering from heart disease should avoid spending prolonged time in high temperatures and consult their doctors for further guidance on protecting themselves from extreme weather conditions. By taking these precautions, individuals can reduce their risk of suffering a heart attack during heat waves and high levels of fine particulate pollution.
In conclusion, this study highlights the increased risk of heart attacks among certain groups of people during heat waves and fine particulate pollution. By taking preventive measures and seeking medical advice, individuals can protect themselves and lower their risk of heart-related issues during extreme weather conditions.
