Brief Summary:
This registry will provide detailed patient demographics and characteristics at the time of enrollment and will also provide data regarding predictors of clinical outcomes such as heart failure decompensation, heart failure hospitalization, NYHA class, and quality of life.

Condition or disease Intervention/treatment
Heart Failure Device: cardiac resynchronization therapy

Detailed Description:
The CRT RENEWAL Registry aims to characterize patient demographics and clinical attributes at enrollment and overall event rates as defined by heart failure decompensation, heart failure hospitalization, death, and ventricular arrhythmic events. The registry will also assess clinical outcomes including quality of life (QOL), physical activity habits, and events rates, along with device diagnostics such as Activity Log Index and heart rate
