What is the primary goal of CRT in heart failure management?

The primary goal of Cardiac Resynchronization Therapy (CRT) in heart failure management is to improve functional status. CRT is specifically designed for patients with heart failure who have ventricular dyssynchrony, often evidenced by a wide QRS complex on an electrocardiogram. The therapy involves the use of a specialized pacemaker that coordinates the contractions of the heart's ventricles, thus optimizing cardiac output and improving the heart's efficiency.

By enhancing the synchronization of heart contractions, CRT helps patients experience fewer symptoms and an overall improvement in their daily activities and quality of life. This is crucial for heart failure patients, who often struggle with limitations due to fatigue, shortness of breath, and other debilitating symptoms. Therefore, while CRT may also influence heart rate, medication requirements, and symptom relief, its primary focus is on improving the patient’s functional capabilities and well-being in everyday life. This is why improving functional status is considered the most significant and direct goal of CRT in heart failure management.
