Patients who do not fulfill criteria for hypertrophic cardiomyopathy but have unexplained giant T-wave inversion: a cardiovascular magnetic resonance mid-term follow-up study

Table 4 Subgroup analysis of the changes of wall thickness in basal, mid and apical left ventricle

	Group 1(G1)			Group 2(G2)			p for Baseline	p for Follow-up	p for change
	Baseline (n = 16)	Follow-up (n = 16)	Change /yr	Baseline (n = 55)	Follow-up (n = 55)	Change /yr	p for Baseline	p for Follow-up	p for change
Basal (mm)	8.3 ± 0.9	8.5 ± 0.9	0.09 ± 0.03	7.9 ± 0.9	8.1 ± 0.9	0.12 ± 0.05	0.167	0.127	0.003
Middle (mm)	7.5 ± 1.2	7.7 ± 1.2	0.08 ± 0.02	7.0 ± 1.2	7.2 ± 1.3	0.11 ± 0.06	0.122	0.109	0.002
Apical (mm)	8.6 ± 1.0	10.7 ± 1.2	0.75 ± 0.16	7.0 ± 1.1	7.5 ± 1.2	0.26 ± 0.14	< 0.001	< 0.001	< 0.001

P < 0.05 is considered significant. Basal = mean thickness of segment 1–6, Middle = mean thickness of segment 7–12, Apical = mean thickness of segment 13–16
