Which medication is part of acute management for congestive heart failure?

• A. ACE Inhibitors
• B. Metoprolol
• C. Nitroglycerin
• D. Calcium Channel Blocker

Answer: (C)

In acute congestive heart failure, the priority is rapid relief of pulmonary congestion and reduction of filling pressures. Nitroglycerin does this quickly by causing venodilation, which lowers left ventricular preload. That fast decrease in preload reduces pulmonary venous pressure and edema, often improving shortness of breath within minutes when given IV, making it a mainstay in acute decompensation. ACE inhibitors are important for long-term management and can be used in the acute setting if the patient is stable, but they don’t provide the same rapid venodilatory relief as nitroglycerin. Beta-blockers like metoprolol are usually avoided during acute decompensation because further decreasing heart rate and contractility can worsen symptoms. Calcium channel blockers aren’t preferred in the acute phase of decompensated heart failure with reduced ejection fraction due to negative inotropic effects and potential hemodynamic instability.
