Sensitivity, specificity, positive predictive value and negative predictive value of different cut-off points of the score in patients with an echocardiogram performed.

Cut-off point	Sensitivity (%)	Specificity (%)	Positive predictive value (%)	Negative predictive value (%)
≥ 2 points	100	35.3	20.2	100
≥ 3 points	100	39.7	21.4	100
≥ 4 points	83.3	80.4	41.1	96.7
≥ 5 points	50.0	98.5	84.5	92.2
≥ 6 points	16.7	100	100	87.9

Positive and negative predictive values are calculated using a population prevalence equal to the prevalence found in our registry (14.2%).
