Bad heart may be due to impaired cardiac function, arrhythmia, myocardial ischemia, plaque formation, heart failure and many other reasons, can be symptomatic treatment were prescribed to take nutritive myocardial drugs, antiarrhythmics, coronary artery dilation drugs, anti-platelet aggregation/anticoagulation/lipid-lowering drugs and cardiotonic drugs. 1. Nutritional myocardial drugs: including sodium creatine phosphate, 1-6 diphosphate fructose, coenzyme Q10, etc., which can nourish myocardial cells and promote the recovery of myocardial cell function. 2. Anti-arrhythmic drugs: including propafenone, metoprolol, amiodarone, verapamil and other drugs, according to the type of arrhythmia to choose the right drug. 3. Coronary artery dilation drugs: including nitroglycerin, isosorbide nitrate, etc., can dilate blood vessels, restore myocardial blood supply, mainly used in patients with coronary heart disease. 4. Antiplatelet aggregation/anticoagulation/lipid-lowering drugs: mainly including aspirin, heparin, atorvastatin, etc. These drugs can inhibit thrombosis and stabilize plaque, mainly used in angina pectoris and myocardial infarction adjuvant therapy. 5. Cardiotonic drugs: including digitalis, digoxin, etc., can enhance myocardial contractility, improve cardiac ejection, mainly used in heart failure patients.
