Angina is an important clinical symptom of coronary atherosclerotic heart disease (CHD). The cause of this disease is generally thought to be that coronary artery atherosclerosis caused stenosis and myocardial blood supply insufficiency, leading to imbalance between myocardial oxygen demand and support. Currently anti-angina drugs being used play a role by reducing myocardial oxygen consumption and / or increase myocardial oxygen supply.
There are medicine for preventing and treating angina such as:
1. nitrates and sodium nitrates: nitroglycerin represented;
2. βblockers: such as propranolol, etc. (see Chapter 6);
3. calcium antagonists: such as nifedipine amlodipine, diltiazem, etc.;
4. other anti-angina drugs: such as dipyridamole (dipyridamole), trimetazidine and so on.
