The first thing you need to do is to make a clear diagnosis, such as stable angina pectoris, myocardial infarction, hypertrophic cardiomyopathy, etc., which needs to be relieved by causative treatment, medication, surgery, and so on. 1. Stable angina pectoris: in acute attacks, under the guidance of doctors, apply nitroglycerin, isosorbide nitrate, etc. to relieve vasospasm, and also apply drugs to improve ischemia and reduce symptoms, such as verapamil, etc.; and apply coronary artery bypass grafting to restore the damaged myocardial blood supply. 2. Myocardial infarction: it is necessary to inhale oxygen in time, set up intravenous channel to keep the route of drug administration open, etc. Morphine and nitrate drugs can be used to reduce pain, and antiplatelet and anticoagulant drugs can be used, such as aspirin and heparin. 3. Hypertrophic cardiomyopathy: application of non-dihydropyridine calcium channel blockers, diuretics, spironolactone, etc. is needed; for patients with ineffective drug treatment and cardiac insufficiency, surgery needs to be considered if there is severe outflow tract obstruction. It is recommended that when the organism is difficult to heart, timely consultation, identify the causes, and standardized treatment under the guidance of the doctor.
