Coronary heart disease is caused by atherosclerosis causing narrowing of the arterial lumen and resulting in myocardial hypoxia. Although there are many new technologies for the treatment of coronary heart disease and angina pectoris, drug treatment is still an important method. The first purpose is to increase the blood oxygen supply or reduce the consumption of myocardial blood oxygen by dilating the coronary arteries; the second is to slowly expand the coronary arteries over a long period of time to expand and thicken the peripheral arteries that have blocked the blood vessels, and gradually establish cardiac collateral circulation. Improve myocardial ischemia status. For this reason, the treatment of coronary heart disease requires long-term medication.
Clinical practice has proved that the more effective drugs for the treatment of coronary heart disease are roughly divided into four categories: the first category of nitrates, such as nitroglycerin, is used for sudden attacks of coronary heart disease and angina pectoris. Sublingual administration can quickly It can relieve chest pain; it can also be used to prevent the occurrence of angina pectoris. Some people may experience headaches and head bloating when taking the above-mentioned drugs at the initial stage. This is because the drugs also cause cerebral blood vessels to dilate. Just reduce the dosage, for example, start with 1/3 or 1/2 tablets, and then gradually increase to the usual dosage; or take the medicine after meals to slow down the absorption of the medicine, and then change to taking the medicine on an empty stomach after getting used to it. If angina pectoris is prone to occur at night, you can use a nitroglycerin patch. This film is replaced every 24 hours. When the film is placed on the chest, the medicine can be absorbed slowly and evenly, preventing the patient from getting up at night to take medicine. The second category is calcium ion antagonists. Commonly used drugs include verapamil, acetaminophen, etc., which are suitable for patients with arrhythmia or high blood pressure. The third category is beta-blockers, which include propranolol, propranolol, betaloc, etc., and can be used for patients with coronary heart disease who have a fast heart rate. The fourth category of medicines are Chinese herbal medicines. Commonly used Chinese patent medicines include Suxiao Jiuxin Pills, Compound Danshen Tablets, Di'ao Xinxuekang, Shenshao Tablets, etc., which have the effects of activating blood circulation and removing blood stasis, promoting yang and relieving numbness, opening the chest and eliminating phlegm, and opening the mind with fragrance.
When taking drugs to treat coronary heart disease, you must follow the following principles: ① Take a combination of Chinese and Western medicine according to the condition; ② Take the medicine according to the pattern of angina pectoris attacks; if angina pectoris tends to occur at night, then do not take it. The medicines are all taken during the day, and the interval between two doses can be lengthened. The last medicine should be taken before going to bed, or a nitroglycerin patch can be applied before going to bed. ③ Preventive medication can be used. For example, if angina pectoris occurs during defecation or various When engaging in various activities (brushing teeth, after meals, giving lectures, driving, watching football games, etc.), taking medicine half an hour before engaging in these activities can achieve the purpose of preventing angina pectoris.
