The specific medication for chronic heart failure needs to be based on the triggers and heart failure grading to choose the appropriate medication. 1. Chronic heart failure: the more common cause is infection, especially respiratory tract infection; therefore, when using medication, we need to improve the blood routine, chest CT, bacterial culture and drug sensitivity test, so as to choose the sensitive antibiotics such as ceftazidime, ceftriaxone and other antibiotics to carry out the treatment. 2. Grade I heart failure: various risk factors need to be actively controlled; usually hypertension and diabetes need to be treated with antihypertensive and hypoglycemic drugs, and if there are multiple risk factors, drugs such as enalapril or valsartan may need to be applied. 3. Second- and third-degree heart failure: for people with acute myocardial infarction or low left ventricular ejection fraction, drugs such as metoprolol, hydrochlorothiazide and spironolactone can be added on the basis of first-degree heart failure. 4. Grade IV heart failure: In addition to the above treatment measures, drugs such as cediran and dobutamine are needed if necessary. When chronic heart failure occurs, it is recommended to consult the cardiovascular medicine department in time, and the doctor will decide the specific medication plan after comprehensive evaluation of the condition.
