Heart attacks and Snow: GMC tells what’s to do

Srinagar: The Government Medical College (GMC), Srinagar, has released an advisory highlighting the increased risk of heart attacks, particularly during the cold winter months. The advisory emphasizes the dangers posed by two significant factors: cold weather and air pollution, both of which can exacerbate cardiovascular conditions.
Heart attacks: A concern in cold weather
Heart attacks, or myocardial infarction (MI), remain one of the leading causes of mortality and morbidity worldwide. Alarming statistics indicate that someone experiences a heart attack every 40 seconds globally. The advisory, citing a recent study published in the Journal of the American College of Cardiology, underlines the role of environmental factors such as low temperatures and polluted air in triggering these life-threatening events.
Impact of cold weather on heart health
Cold weather has been established as a critical factor in increasing the risk of both minor and major heart attacks.
Global Statistics: Approximately 10 million people experience cold-related disabilities annually, with 500,000 deaths attributed to low temperatures.
Mechanism: Cold temperatures constrict blood vessels, increasing blood pressure and the workload on the heart. Furthermore, exposure to cold can exacerbate respiratory infections, adding additional stress on cardiovascular health.
Recommendations for high-risk groups
The advisory particularly targets individuals with existing health conditions, including hypertension, diabetes, obesity, smoking history, previous heart attacks, or heart failure. Such individuals are advised to take extra precautions during the winter season to mitigate risks:
Stay Warm
Maintain a comfortable indoor temperature.
Wear appropriate winter clothing, such as hats, gloves, and insulated footwear, while outdoors.
Prevent Respiratory Tract Infections
Limit exposure to cold environments.
Consider influenza vaccinations to lower the risk of respiratory infections.
Modify Outdoor Activities
Avoid strenuous physical activities like jogging or shoveling snow, which can increase the risk of heart attacks.
Studies suggest a link between snow shoveling and cardiac events, prompting the recommendation to stay indoors and avoid heavy work.
