With acute heart failure, patients need immediate emergency medical attention, cardiac monitoring, oxygen, and intravenous medications such as nitroglycerin and sodium nitroprusside. Acute heart failure has a high mortality rate. Immediately after the patient seeks emergency medical care, cardiac monitoring, oxygenation, monitoring vital signs. Ventilator-assisted ventilation therapy is needed if necessary. The patient needs to be placed in a high-restraint position, or even in a sitting position with legs down at the side of the bed, to reduce the amount of returned blood and reduce the load on the heart. Intravenous administration of drugs to strengthen the heart, such as cediran, can enhance myocardial contractility. Give diuretic drugs, such as furosemide diuretic. Vasodilator drugs, such as nitroglycerin dilate blood vessels and reduce cardiac load. Antispasmodic and calming therapy is also needed, requiring the application of dihydroxypropyl theophylline, for example. Even morphine is used for sedation. The principle is cardiotonic, diuretic and vasodilator. During treatment, access must be monitored, and if the urine volume is never successfully excreted, sometimes ultrafiltration therapy is required. Acute heart failure requires prompt consultation in the cardiology department or the emergency department, and active treatment under the guidance of a doctor.
