“The ‘cliff-style’ cooling is a hotbed for cardiovascular and cerebrovascular diseases. Cold weather can cause vasoconstriction, increase blood pressure, increase heart rate, and easily induce myocardial infarction, stroke and other diseases. If the signs of myocardial infarction and stroke can be found in time, and immediate measures can be taken, we can win the opportunity to save lives.” Liu Jian, chief physician of the Department of Cardiovascular Medicine of Peking University People’s Hospital, told the Health Times reporter.

Liu Jian pointed out that the sudden drop in temperature is more likely to cause the occurrence of acute myocardial infarction disease, which is typically manifested in the middle of the chest (retrosternal), or to the left of the middle of the chest (precordial). There is pain in the part, which is not a stinging pain at a certain point, but a pain in the whole piece, which lasts for more than 15 minutes; in addition, pain outside the chest may also occur. About a quarter of patients with acute myocardial infarction do not have typical chest pains, and they may experience burning throat pain; pain in the left shoulder or inner left arm; no dental disease but tooth pain; Vomiting; some patients have symptoms such as back or jaw pain. Increased activity and accompanying symptoms: such as chest tightness, palpitation, suffocation, shortness of breath, profuse sweating, or unusual restlessness.

“If the above symptoms appear without a cause, and the symptoms are getting worse, it may be a myocardial infarction. You should stop activities immediately, rest, and call 120.” Liu Jian reminded.
