Usability of diagnostic tests for cardiac sarcoidosis

	Sensitivity%	Specificity%	PPV%	NPV%	p-value
ECG	92	53	44	94	<0.05
Exercise test	67	90	75	86	<0.01
Holter monitoring	82	50	41	87	0.14
NT-pro-BNP	78	67	58	83	<0.05
TTE	58	93	78	84	<0.01
CMR	100	100	100	100	<0.0001
NT-pro-BNP and ECG (both pathologic)	78	93	87	87	<0.001

ECG=electrocardiogram, CMR=cardiovascular magnetic resonance, TTE=transthoracic echocardiogram, NT-pro-BNP=N-terminal pro B-type natriuretic peptide, PPV=positive predictive value, NPV=negative predictive value.
