What is an indication for milrinone?

A. Acute heart failure: Milrinone is a phosphodiesterase-3 inhibitor that increases cardiac contractility and promotes vasodilation. It is indicated for short-term management of acute decompensated heart failure, especially when conventional therapies are insufficient. B. Atrial fibrillation: Milrinone does not have a primary role in managing atrial fibrillation. Antiarrhythmic medications, rate control agents, or anticoagulants are preferred for this condition. C. Chronic stable angina: Milrinone is not indicated for chronic stable angina. Antianginal therapies such as nitrates, beta-blockers, or calcium channel blockers are more appropriate for symptom management in this condition. D. Chronic hypertension: Milrinone is not used for chronic hypertension management. Its potent inotropic and vasodilatory effects are designed for acute cardiac support rather than long-term blood pressure control.
