Prevalence of pre-transplant electrocardiographic abnormalities and post-transplant cardiac events in patients with liver cirrhosis

Table 4 Standardized incidence ratios for cardiac events in patients with cirrhosis (n = 234) following liver transplantation

	Observed person years	Observed events¹	Expected events²	SIR	95% CI	p-value
Total cardiac events³	728.9	70	13.96	5.014	3.909 - 6.335	<0.001
Total acute coronary syndromes³	728.9	16	4.336	3.69	2.109 - 5.992	<0.001
Total arrhythmic events³	728.9	49	9.624	5.091	3.767 - 6.731	<0.001
Late cardiac events⁴	846.0	31	17.1	1.813	1.232 - 2.573	0.003
Late acute coronary syndrome⁴	846.0	13	5.264	2.469	1.315 - 4.223	0.006
Late arrhythmic events⁴	846.0	14	11.84	1.183	0.647 - 1.984	0.603

SIR, Standardized incidence ratio; CI, Confidence interval. For the calculation of SIRs, data on the occurrence of cardiac events in the general Swedish population were obtained from the national inpatient hospital registry.
¹Observed events; the number of observed events in our cohort.
²Expected events; the number of events that occurred in the age and gender matched group of the general population.
³All events occurring after liver transplantation until death or end of follow-up.
⁴All events occurring after the immediate inpatient post-transplant period.
