Patients with coronary artery disease can be treated with oral quick-acting heart pills during angina attacks, which can usually be taken sublingually, as the sublingual mucosa absorbs the drug more quickly and can play a role in activating blood circulation and relieving pain. If the symptoms are more serious, it is recommended that the patient take sublingual nitroglycerin to dilate the coronary arteries, and oral anti-platelet aggregation drugs, such as aspirin and plaque stabilization drugs to relieve the symptoms. It is recommended that these patients have a coronary CT or coronary angiography to clarify the degree of stenosis and the extent of stenosis for the next step of treatment. These patients may have triggers such as exertion, mood swings or satiety or cold stimulation during the onset of symptoms, so they should be advised to avoid these factors. However, quick-acting heart pills are only for emergency use, if the effect is not obvious after sublingual administration, it is recommended to call 120 for medical attention as soon as possible.
