What is STEMI and how does it happen?
STEMI is a type of heart attack that occurs when a blood clot blocks one of the major arteries that supply blood to the heart. This causes a sudden interruption of blood flow and oxygen to the heart muscle, which can lead to irreversible damage or death.Cold weather can trigger STEMI by affecting the cardiovascular system in several ways. First, cold weather causes the blood vessels to constrict, which increases blood pressure and reduces blood circulation. This puts more strain on the heart and increases its oxygen demand. Second, cold weather can make the blood thicker and more prone to clotting, which can lead to a blockage in the arteries. Third, cold weather can increase the risk of respiratory infections, which can also trigger inflammation and clotting in the blood vessels.

Who is at risk and how to prevent it?
Anyone can have a heart attack, but some people are more vulnerable than others. People with existing cardiovascular diseases, such as high blood pressure, high cholesterol, diabetes, or previous heart problems, are at higher risk of STEMI during cold weather. Men are also more likely to have STEMI than women, according to some studies.The best way to prevent STEMI is to avoid exposure to cold weather and sudden exertion, such as shoveling snow or walking through heavy snow. If you have to go outside, dress warmly and cover your head, neck, and chest. Avoid alcohol and smoking, as they can impair your body’s ability to regulate temperature and blood flow. If you have any symptoms of a heart attack, such as chest pain, shortness of breath, nausea, sweating, or dizziness, seek immediate medical attention.
Cold weather can be a silent killer for your heart. Be aware of the signs and symptoms of STEMI and take precautions to protect yourself and your loved ones. Remember, every minute counts when it comes to saving your heart.
