Table 2:

Pulmonary artery acceleration time measures over the 1^st week.

	Day 1	Day 2	Day 5 – 7	p
Entire cohort
Number of infants	132	132	98
PAAT (msec)	44 ± 4	46 ± 4^*^†	48 ± 5^*^†	0.001
PAAT/RVET	0.24 ± 0.02	0.26 ± 0.01^*	0.28 ± 0.03^*^†	0.001
Healthy uncomplicated cohort
Number of infants	65	65	36
PAAT (msec)	44 ± 3	47 ± 3^*^†	49 ± 6^*^†	<0.001
PAAT/RVET	0.25 ± 0.02	0.27 ± 0.01^*^†	0.29 ± 0.03^*^†	<0.001

Values are presented as mean (standard deviation). One way ANOVA with repeated measures was used to assess the change in values over time. * = p < 0.05 compared with previous day measurement;

^†

= p < 0.05 compared with Day 1 measurement (with Bonferroni adjustment).

PAAT, pulmonart artery acceleration time

RVET, right ventricle ejection time
