As we enter winter, the number of patients with acute cardiovascular disease attacks increases significantly. How can heart disease patients pay attention to prevention in winter? Cold weather leads to vasoconstriction, heart attack, heart failure and cardiovascular death and other sudden events in heart disease patients are significantly more likely to occur, heart attack in winter is 2-3 times higher than other seasons, arrhythmia, heart attack is again one of the most important causes of death in heart disease patients. Patients should seek medical attention as soon as they have symptoms of discomfort, because the best time to resuscitate cardiac arrest, severe arrhythmia and massive myocardial infarction is not more than 5 minutes. How can patients with severe heart disease get through this difficult winter “hurdle”? 1. Self-monitoring. Before the weather turns cold, you should have a formal physical examination to assess your overall health and disease risk, including blood pressure, blood lipids and blood sugar, and to evaluate myocardial ischemia and heart function. 2. Keep warm and prevent cold. Avoid washing your face and feet with cold water, avoid stepping out suddenly from a warm room, especially when it is windy, rainy or cold, and go out to get used to it before you go out, and keep a good supply of common emergency drugs for heart disease, such as nitroglycerin tablets, aspirin and heartburn. 3, do not go out after a full meal. Because after a full meal more blood rushes to the gastrointestinal tract, so that the heart and liver itself blood supply is relatively reduced, easy to cause thrombosis and induce coronary heart disease – arrhythmia. 4. It is not recommended to participate in outdoor physical activities and exercise to avoid overexertion. Forbid to eat cold and raw food, keep a good state of mind!
