Aspirin, nitroglycerin, quick acting heart saving pills and other common drugs are regarded as "life-saving drugs" by many patients with cardiovascular and cerebrovascular diseases. However, after reading the following news, I'm afraid everyone will be confused. According to a news report, Aunt Zhang in her 60s, because of the pain in the precordial area, remembered that she had seen in her circle of friends that chewing a few aspirin in an emergency could relieve "heart disease", so she took aspirin on her own without going to the hospital for treatment in time, and nearly died... Why? Today, pharmacists are here to popularize the difference in efficacy and correct use of these "first-aid drugs" for the treatment of cardiovascular and cerebrovascular diseases. Two kinds of drugs can be used for emergency treatment of sudden chest pain in patients with coronary heart disease. Aspirin is an antiplatelet drug, which is commonly used for the primary and secondary prevention of coronary heart disease. People who have suffered from cardiovascular and cerebrovascular diseases and are likely to suffer from cardiovascular and cerebrovascular diseases are most suitable for long-term regular use. Nitroglycerin is a drug to dilate blood vessels. It is often used to relieve angina pectoris in patients with confirmed coronary heart disease. It is generally used for first aid. Quick acting Jiuxin Pill is a Chinese patent medicine containing Chuanxiong and borneol. It is not clearly diagnosed as coronary heart disease, but the high-risk group of coronary heart disease with high blood pressure and blood lipid and angina pectoris can carry quick acting Jiuxin Pill to relieve sudden chest tightness. Quick acting Jiuxin Pill can also be taken regularly for a long time under the guidance of doctors to prevent and treat cardiovascular and cerebrovascular diseases. So, can all these three drugs be used as first aid medicine? For the patients with confirmed coronary heart disease, aspirin can also have certain effects in case of sudden chest pain, but it is not used as an emergency medicine in general. In case of acute chest pain, nitroglycerin or quick acting heart saving pills should be taken under the tongue immediately. The causes of fatal chest pain are different and the medication is different. Since aspirin has certain effects on chest pain of patients with coronary heart disease, why did the elderly in the news nearly die when taking aspirin for chest pain? This is because different types of heart disease take different first-aid measures. In case of sudden chest pain, you should call 120 as soon as possible. At present, the common fatal chest pain can be divided into three types: acute myocardial infarction, aortic dissection and pulmonary embolism. It is difficult for patients to accurately distinguish between them. "Aunt Zhang" in the news saw that the "heart disease" mentioned in the circle of friends should refer to coronary heart disease and acute coronary syndrome, which are typical of chest pain. Aspirin may be effective in patients with sudden angina or myocardial infarction; However, for patients with aortic dissection, the most feared thing is the rupture and bleeding of the dissection. Aspirin has an inhibitory effect on platelet aggregation, which will increase the risk of bleeding. It is very dangerous and fatal for patients with aortic dissection. After Aunt Zhang in the news was finally sent to the hospital for examination, she was a typical aortic dissection. Therefore, I would like to remind you that if you have chest pain for the first time, you'd better call 120 in time to find out the cause of chest pain so as to choose the correct first aid measures. Aspirin is the drug that patients with coronary heart disease need to take regularly for a long time under the guidance of doctors. It should be noted that the common aspirin in the market is enteric coated tablets, which need to be taken on an empty stomach. Many people mistakenly think that aspirin hurts their stomach and take it after meals. In fact, it is a big mistake. Enteric coated tablets
