Comparison of left ventricular and left atrial dimensions between asymptomatic and symptomatic HCM patients.

	Asymptomatic HCM (n = 41)	Symptomatic HCM (n = 46)	p-value
Atrial fibrillation	17 (41%)	20(43%)	0.68
None	24(59%)	26(57%)	0.97
Paroxysmal	15(37%)	12(26%)	0.41
Persistent	2(5%)	8(17%)	0.13
LV ejection fraction (%)	60 ± 10	58 ± 9.5	0.32
LV mass (gr·m-2)	99 ± 30	97 ± 34	0.84
LV end systolic volume (ml·m-2)	29 ± 13	37 ± 13	0.04
LA volume (ml·m-2)	48 ± 21	59 ± 23	0.03
Extent of LGE (%)	6.0 ± 9.0	11 ± 13	0.03

Data are presented as ± standard deviation. Volumes are indexed to body surface area. HCM = hypertrophic cardiomyopathy patients, LA = left atrial. LGE = late gadolinium enhancement, LV = left ventricular
