Frequency distribution of cardiac enzymes among patients of both groups, LR DN (modified del Nido) and PL DN groups (conventional del Nido solution), at different measurement points.

Groups		LR DN	PL DN	p-value
Variables		(mean ± SD)	(mean ± SD)	p-value
Preoperative	CPK (ng/mL)	111 ± 117	101 ± 187.25	0.32
Preoperative	cTnI (ng/mL)	1.6 ± 4.79	1.52 ± 2.68	0.81
Post-declamp	CPK (ng/mL)	233 ± 314.85	248 ± 112	0.71
Post-declamp	cTnI (ng/mL)	1.85 ± 4.22	1.92 ± 2.82	0.24
ICU admission	CPK (ng/mL)	390 ± 351	383.50 ± 160.75	0.22
ICU admission	cTnI (ng/mL)	2.20 ± 3.54	2.15 ± 2.60	0.005^#
24 h after ICU admission	CPK (ng/mL)	437 ± 215	270.50 ± 199.25	0.18
24 h after ICU admission	cTnI (ng/mL)	2.26 ± 3.90	1.79 ± 1.03	0.03

CPK: creatine phosphokinase, CPK-MB: creatine phosphokinase-MB, LDH: lactate dehydrogenase, cTnI: cardiac troponin I, ICU: intensive care unit, IQR: interquartile range.

There is a significant difference between groups (p < 0.05).
