Postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting or cardiac valve surgery: intraoperative use of landiolol

Table 2 Systolic and diastolic blood pressure and heart rate in the two groups

	Group	Before induction	After induction	Start of operation	Sternotomy	End of operation
SBP (mm Hg)	Control	136 ± 18	88 ± 12	115 ± 19	128 ± 15	115 ± 19
SBP (mm Hg)	Landiolol	139 ± 24	93 ± 13	120 ± 19	137 ± 18*	118 ± 19
DBP (mm Hg)	Control	69 ± 16	44 ± 7	56 ± 11	63 ± 12	54 ± 9
DBP (mm Hg)	Landiolol	72 ± 17	46 ± 10	58 ± 14	65 ± 15	56 ± 11
HR (beats/min)	Control	68 ± 12	54 ± 10	59 ± 11	65 ± 8	76 ± 9
	Landiolol	70 ± 12	58 ± 13	63 ± 11*	71 ± 12*	75 ± 15

Values are shown as the mean ± SD. *P<0.05 vs. control (unpaired t-test). SBP: systolic blood pressure, DBP: diastolic blood pressure, HR: heart rate.
Repeated measures ANOVA showed significant differences between the groups for SBP (p=0.03) and HR (p=0.02). SBP was significantly higher in the landiolol group at the start of the operation. SBP and HR were significantly higher in the landiolol group at sternotomy. DBP was similar in both groups.
