The application of quick-acting heart pills is mainly used for patients with coronary heart disease and angina pectoris. During an attack of angina pectoris, due to the local narrowing or spasm of the coronary arteries resulting in insufficient blood and oxygen supply, localized myocardium becomes ischemic and hypoxic, and eventually angina pectoris symptoms appear. Oral quick-acting heart pills can improve the patient’s angina symptoms by dilating the coronary arteries and improving spasm. For example, if a patient has heart failure, hypertrophic cardiomyopathy or other types of heart disease such as congenital heart disease, the oral use of rapid-acting heart pills is not effective because they are mainly used for the treatment of coronary heart disease and have no effect on other heart diseases. Patients like menopausal patients or patients with severe vegetative dysfunction without specific coronary artery stenosis are also not recommended to take orally.
