The time of discharge after heart failure resuscitation is usually determined by the patient’s symptoms, the effectiveness of the treatment and the condition of the patient. In mild cases, it takes about 1 week, and in more severe cases, it can take up to half a month or even longer. 1. Mild heart failure: generally manifested as chest tightness, shortness of breath, low urine, edema and other conditions. There are even manifestations such as nocturnal paroxysmal dyspnea. After bisoprolol and other drug treatment symptoms improve, manifested in chest tightness, shortness of breath, dyspnea and other symptoms of relief, the general treatment time of about 1 week or so to reach the discharge standard. 2. Severe heart failure: symptoms such as wheezing, palpitations, profuse sweating, jugular vein distension, etc. Generally, after conventional etiological treatments and anti-heart failure treatments, such as oxygen intake, salt restriction, the use of diuretics (e.g., hydrochlorothiazide, etc.) and other treatments, the symptoms are still difficult to control, or deteriorate progressively. Therefore, the hospitalization period is longer, up to half a month or even longer. After being discharged from the hospital, patients should continue their heart failure treatment without interruption, because heart failure treatment is a long-term process. After returning home, patients should be careful not to drink too much water, catch a cold, or overexert themselves. If heart failure occurs, the patient should be admitted to the hospital and treated according to the doctor’s instructions.
