The primary treatment goal in managing stress-induced cardiomyopathy is to decrease preload. This condition, often referred to as "takotsubo syndrome," results from acute stress that leads to transient dysfunction of the heart muscle. In this context, patients experience symptoms similar to those of a heart attack, including chest pain and shortness of breath, but without significant coronary artery disease.

By decreasing preload, which refers to the volume of blood in the ventricles at the end of diastole, healthcare providers aim to reduce the workload on the heart and alleviate symptoms. Managing preload can also help prevent further deterioration of cardiac function, allowing the heart to recover more effectively from the stress-induced episode.

The other treatment strategies, while they may be relevant in specific cases, do not address the primary underlying issues related to stress-induced cardiomyopathy. Increasing contractility could place extra strain on the heart during a time when it’s already compromised. Reducing heart rate is important in some cardiac conditions but in stress-induced cardiomyopathy, the focus is often on managing fluid status and decreasing overload. Increasing afterload would further challenge the heart by raising systemic vascular resistance, which is counterproductive in this setting. Thus, the reduction of preload stands as the cornerstone of acute management in
