What type of medication effect can lead to heart failure readmission?

The correct answer is related to cardiac depressants, which can negatively impact heart function. Cardiac depressants are medications that can decrease myocardial contractility, leading to reduced heart function and potentially precipitating heart failure complications. These include certain classes of medications like beta-blockers (when not properly dosed), calcium channel blockers, or sedatives that may affect the heart's ability to pump effectively. When heart function is compromised, it can lead to symptoms of heart failure worsening and may result in hospital readmission.

In contrast, while antibiotics and pain relief medications are vital in treating infections and managing pain, they typically do not have direct effects on heart function that would lead to readmission due to heart failure. Vitamins and supplements, while sometimes beneficial for overall health, are generally not associated with causing exacerbations of heart failure. Therefore, medications that suppress heart function are more critical in this context as they can directly relate to the risk of readmission for heart failure patients.
