Doppler indices based on DTI of the lateral mitral ring and colour M-mode propagation velocity obtained in protocol B, according to the level of invasive PAOP measured during RHC

	PAOP ≤ 18 mmHg (n = 24)	PAOP > 18 mmHg (n = 8)	p Value
Vp (cm/s)	45 ± 10	35 ± 8	0.05
E' lateral (cm/s)	12.9 ± 3.9	9.2 ± 1.3	0.01
E/Vp	1.7 ± 0.6	2.7 ± 0.5	0.0006
E/E' lateral	5.9 ± 2.2	10.6 ± 3.3	0.0002

Abbreviations: DTI, Doppler tissue imaging; PAOP, pulmonary artery occlusion pressure; RHC, right heart catheterisation; Vp, propagation velocity of early diastolic blood flow within the LV measured using colour M-mode.
