Table 3. Dynamic changes of WBC and their subpopulation after TAVR for patients ≥ 80 yrs.

	Admission	24-h	72-h	6-month	P1	P2	P3
Values are (median [IQR]). P1: comparison of pre-procedural values with those at 24 h; P2: comparison of pre-procedural values with those at 72 h; P3: comparison of pre-procedural values with those at 6 months; NL: neutrophil to lymphocyte; TAVR: transcatheter aortic valve replacement; WBC: white blood cells.
