SRINAGAR: The Government Medical College (GMC) Srinagar has issued an advisory warning about the increased risks of heart attacks during the winter months, particularly due to cold weather and air pollution. Myocardial Infarction (MI), commonly known as a heart attack, is one of the leading causes of death globally, with a heart attack occurring every 40 seconds. A recent study published in the Journal of the American College of Cardiology has highlighted cold temperatures and air pollution as significant triggers for heart attacks.
The study revealed that cold weather contributes to 10 million cases of disability and 500,000 deaths globally each year. Exposure to low temperatures can cause blood vessels to constrict, which increases blood pressure and places additional strain on the heart. Furthermore, cold weather can exacerbate respiratory infections, further stressing cardiovascular health. Alongside the cold, air pollution has been identified as another major risk factor. Pollutants in the air can cause systemic inflammation and impair the cardiovascular system, making the heart more vulnerable to attacks.
In light of these findings, GMC Srinagar has issued specific recommendations for individuals at higher risk of heart attacks, such as those with hypertension, diabetes, obesity, a history of smoking, or previous heart conditions. High-risk individuals are urged to take extra precautions during winter. It is advised that they maintain a warm indoor environment using proper heating and wear warm clothing, including hats, gloves, and insulated footwear when venturing outdoors. To reduce the risk of respiratory tract infections, individuals should avoid unnecessary exposure to cold environments and consider influenza vaccinations.
The advisory also suggests modifying outdoor activities during cold weather, specifically advising against strenuous physical tasks such as outdoor jogging, which can increase the risk of cardiac events. There is emerging evidence linking snow shovelling and other heavy physical activities to heart attacks, and as such, people are encouraged to stay inside, stay warm, and avoid such strenuous tasks.
The GMC Srinagar emphasizes that by staying warm and minimizing exposure to cold and air pollution, individuals, especially those in high-risk groups, can significantly reduce the likelihood of a heart attack. The advisory serves as a reminder that with the right precautions, the risks associated with winter weather can be managed effectively.
