Myocardial infarction is a serious heart disease caused by coronary artery narrowing and blockage, leading to myocardial ischemia and hypoxia, and necrosis, particularly in cases of extensive myocardial infarction. If not effectively treated, it can lead to severe complications such as heart failure, cardiogenic shock, and arrhythmias. Therefore, it is essential to follow a doctor's guidance and use effective medications for emergency treatment. In daily life, it is important to maintain a pleasant mood, avoid irritability, consume easily digestible food, quit smoking and drinking, and primarily follow a low-fat, low-salt diet to keep the bowel movements regular. This helps prevent worsening of the condition due to improper diet and constipation, which can increase the cardiac burden.
