Table 3 Comparison of patients with and without LVH.

	Patients with LVH	Patients without LVH	p Value
Men/women (n)	9/10	6/14	0.33
Age (years)	53 (26 – 69)	45 (22 – 65)	0.28
Mutant heteroplasmy in muscle (%)	73 (48 – 83)	64 (30 – 91)	0.34
BEHL_{0.5 kHz-4 kHz} (dB)	53 (0 – 103)	29 (0 – 64)	0.022

LVH was diagnosed if septal or posterior wall end-diastolic thickness ≥ 12 mm in non-hypertensives and ≥ 14 mm in medically treated hypertensives [23]. BEHL_{0.5–4 kHz}, better ear hearing level over the frequencies 0.5 kHz, 1 kHz, 2 kHz and 4 kHz. The values are medians (range)
