In Stage D heart failure, which therapy is generally not indicated because it can worsen symptoms?

Explanation:
In end-stage heart failure, the focus is on relieving symptoms and avoiding medications that can further depress the heart’s function. Antidysrhythmic medications often have negative inotropic effects and can prolong the QT interval, increasing the risk of dangerous arrhythmias. In Stage D, where the heart already struggles to maintain adequate output, these risks mean antiarrhythmic drugs can worsen symptoms and overall stability, making them generally not indicated. Other therapies like diuretics to reduce congestion and agents that support remodeling and afterload (when feasible) are favored to improve quality of life.
