Multiple Choice

Which medication is commonly used in the management of cardiogenic shock or heart failure?

Inotropy is the main idea here: digoxin provides a positive inotropic effect and helps with rate control in certain arrhythmias, making it a traditional option for managing heart failure. It works by inhibiting the Na+/K+ ATPase pump in heart cells, which increases intracellular calcium and strengthens cardiac contractions. This can improve stroke volume and symptoms in patients with chronic heart failure and reduced ejection fraction, and it can also help with ventricular rate control in atrial fibrillation, contributing to better overall function and fewer hospitalizations. In contrast, a vasopressor like norepinephrine may be used in acute cardiogenic shock to raise blood pressure and perfusion, but it’s not a long-term heart failure therapy. Mannitol is an osmotic diuretic used for other indications and can worsen volume status in heart failure if not carefully managed. Aminophylline is a bronchodilator, not a heart failure drug. So, the drug that is commonly used to manage heart failure over the longer term, and can be beneficial for symptom relief, is digoxin.
