Effect of cardiac resynchronization therapy on estimated glomerular filtration rate (A) and blood urea nitrogen (B) in category C patients (i.e. 30≤eGFR<60 mL/min/1.73m2) with and without beta blocker medication at baseline. BUN, blood urea nitrogen, CRT, cardiac resynchronization therapy, eGFR, estimated glomerular filtration rate.
