Oedema caused by heart disease is considered to be due to heart failure and is mainly treated with diuretic, vasodilator, cardiac and other symptomatic support. Diuretic mainly choose drugs like furosemide and torasemide, generally you can push 20-40mg of furosemide first, if the effect is not significant, you can also increase the dose or change the way of administration, if necessary, you can also switch to torasemide. While diuretic, it can also be combined with vasodilator therapy, the most widely used clinically is sodium nitroprusside, this drug is relatively inexpensive and effective. If the patient has more serious heart failure and BNP is significantly elevated, he can also choose to apply neostigmine, which can improve the symptoms of heart failure relatively better. Diuretics may gradually become resistant during the application process, and the patient’s daily urine volume should be used to determine whether the current dose needs to be increased.
