Acute heart failure refers to the acute onset or exacerbation of a clinical syndrome of heart failure, manifested as either acute onset of new heart failure or acute worsening of chronic heart failure. The goal of treatment is to improve symptoms, stabilize hemodynamic status, protect vital organ functions, improve prognosis, and prevent recurrence. Because the ischemia and hypoxia during an acute heart failure episode, along with severe respiratory distress, are life-threatening, urgent intervention is required. However, whether it can be cured depends on the underlying disease. Since the underlying disease is already present, it cannot be completely cured, but clinical symptoms and prognosis can be improved.
