If an elderly person develops acute heart failure, then prompt resuscitation treatment must be performed. The first step is to adjust the patient’s position. It is recommended that the patient should be in a semi-recumbent or sitting position with legs down and be given high-flow nasal cannula oxygen immediately. At the same time, intravenous access should be opened, and ECG, blood pressure pulse and blood saturation should be monitored to help monitor the patient’s vital signs at all times. After general management, medication should be administered promptly, starting with furosemide at a dose of 20 to 40 mg, which can be repeated every four hours. For patients with dyspnea and wheezing, aminophylline can also be administered. Theophyllines help to enhance myocardial contractility and also dilate the peripheral blood vessels. If the patient’s heart rate is currently fast, especially if the patient is in atrial fibrillation, then Cediran can also be administered. After the above drug therapy, vasoactive drugs can be given, such as intravenous sodium nitroprusside, which is a relatively common drug in acute left heart failure. The rate of sodium nitroprusside pumping is adjusted according to the patient’s condition and actual blood pressure. If the patient is not diuretic-sensitive, then furosemide can also be replaced with oral tolvaptan. In patients who are diuretic resistant and have severe renal impairment, continuous renal replacement therapy may be an option if necessary. If the patient has a high urine output and is having poor relief of dyspnea and wheezing while pumping sodium nitroprusside again, then it is recommended that the patient consider switching to human recombinant brain natriuretic peptide. This drug helps to reduce the anterior and posterior loads and also dilates the veins and arteries and has some diuretic effect. For patients whose condition does not improve after aggressive systemic medication, then mechanical assisted circulatory support devices may also be an option.
