	Sensitivity %	Specificity %	PPV %	NPV %	AUC	Cut-off value
RV/LV_axial	82	83	68	92	0.84	1.18
RV/LV_4-CH	88	83	71	92	0.87	1.29
RV/LV_volume	88	85	82	95	0.93	1.34

Troponin I g·L⁻¹	67	72	56	80	0.70	0.07

4-CH: four-chamber view; PPV: positive predictive value; NPV: negative predictive value; AUC: area under the curve; NT-pro-BNP: N-terminal pro-brain natriuretic peptide.
