心梗,即“急性心肌梗塞”的简称,近年来该症在我国的发病率有明显上升趋热,“心梗”素以发病急骤,病死率高而著称,据上海市十大医院对20年来收治的3988名急性心梗患者的临床资料分析,每年12月份至次年3月份发病率最高,而这两个季节又是寒潮和强冷空气活动最频繁的时期,故应引起人们的重视。为什么寒冷季节易诱发“心梗”呢?这是因为人体在寒冷环境中全身外周血管收缩,血流阻力加大。血压升高,心肌耗氧量增加,上述因素易使心脏冠状动脉发生痉挛.造成血液循环障碍,故而诱发本病。另外,在寒冷季节由于人们对强冷空气的抵抗力较差,尤其老年人极易发生上呼吸道感染和支
Myocardial infarction, referred to as “acute myocardial infarction” for short, in recent years the incidence of this disease in our country was significantly increased fever, “myocardial infarction” with a sudden onset, high mortality is known, according to Shanghai’s top 10 hospitals on the 20 The clinical data of 3988 patients with acute myocardial infarction treated in recent years showed that the incidence was highest from December to March next year, and these two seasons were the periods where cold wave and strong cold air activity were the most frequent. Therefore, people should pay more attention . Why the cold season is easy to induce “myocardial infarction”? This is because the human body in a cold environment, peripheral vasoconstriction, increased blood flow resistance. High blood pressure, increased myocardial oxygen consumption, the above factors easily make the heart of coronary artery spasm, resulting in blood circulation disorders, it induced this disease. In addition, in the cold season, people are particularly vulnerable to cold air, especially in the elderly.
