Cardiac morphology in current series compared with echocardiographic data in 225 triathletes studied by Douglas¹⁹

Criterion for LVH	Per cent, Douglas, 199719	Per cent, current series (all cases)	p Value	Per cent, current series (CAD, haemorrhage, aortic dissection excluded)	p Value
Heart mass > threshold*	24	45 (N=20)	0.023	37.5 (N=16)	0.1
Septum ≥1.3 cm	1	67 (N=9)	<0.001	66.7 (N=6)	<0.001
Posterior wall ≥1.3 cm	0.5	50 (N=14)	<0.001	50 (N=10)	<0.001

*Echocardiography (Douglas¹⁹): LV mass >294 g/m in men or >198 g/m in women; autopsy (current series): heart weight >95th centile according to Kitzman as determined from height.¹⁸

CAD, coronary artery disease; LVH, left ventricular hypertrophy.
