	Sensitivity %	Specificity %	PPV %	NPV %	AUC	Cut-off value
RV/LV_axial	83	80	50	95	0.87	1.23
RV/LV_4-CH	83	88	63	96	0.89	1.31
RV/LV_volume	92	88	65	98	0.90	1.33

Troponin I g·L⁻¹	66	70	33	90	0.71	0.09

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.
