Table 2.

Comparison between subgroups of hs-TnI positive versus negative and also between subgroup of lower versus higher NT-proBNT concentration (NS: nonsignificant).

First model—current Holter
	Hs-TnI negative n = 27	Hs-TnI positive n = 19
5-year SCD risk in HCM	3.81 ± 3.23%	6.38 ± 4.17%	P < 0.05
	Lower NT-proBNP n = 23	Higher NT-proBNP n = 23
5-year SCD risk in HCM	4.14 ± 4.18%	5.18 ± 3.63%	NS
Second model—all Holter
	Hs-TnI negative n = 27	Hs-TnI positive n = 19
5-year SCD risk in HCM	4.25 ± 4.20%	6.90 ± 3.99%	P < 0.05
	Lower NT-proBNP n = 23	Higher NT-proBNP n = 23
5-year SCD risk in HCM	4.40 ± 3.62%	6.29 ± 4.18%	NS
