Angina pectoris is mainly caused by myocardial ischemia, commonly due to coronary atherosclerosis, imbalance of coronary oxygen supply and demand, coronary artery myocardial bridge or coronary artery spasm. The cause of angina should be clarified, and coronary CT, cardiac ultrasound and electrocardiogram should be performed to clarify the diagnosis and treatment. The angina attack period is generally used to dilate blood vessels and antispasmodic drugs, remission period can be applied to anti-platelet drugs, lipid-lowering drugs, heart rate control drugs, myocardial drugs and other treatment. 1, dilating drugs: can temporarily relieve the patient’s chest tightness, chest pain symptoms. Clinically commonly used nitroglycerin, can be effective within a few seconds, if sublingual or inhalation effect is faster. You can also take long-term nitrate drugs to prevent angina attacks, such as isosorbide mononitrate, isosorbide mononitrate extended-release tablets, etc. Angiotensin converting enzyme inhibitors or angiotensin receptor antagonists can be taken, such as Benadryl hydrochloride tablets, captopril tablets, etc.; 2, antispasmodics: for angina caused by coronary spasm, some spasm control drugs can be taken, such as diltiazem hydrochloride tablets and other non-dihydropyridine calcium antagonists; 3, anti-platelet drugs: taking anti-platelet drugs can inhibit vasospasm, thereby reducing angina attacks. 4, lipid-lowering drugs: lipid-lowering and plaque-stabilizing drugs can improve the clinical symptoms of angina, commonly used drugs such as atorvastatin, resulvastatin capsules, etc.; 5, heart rate control drugs: can improve myocardial remodeling to relieve angina, such as metoprolol tartrate, bisoprolol fumarate tablets, etc.; 6, myocardial nutrition drugs: taking some myocardial nutrition, improve Myocardial energy metabolism drugs can relieve angina pectoris, such as trimetazidine capsules.
