TABLE II.

Echocardiographic Measurements of Right Ventricular (RV) Function Obtained in Patients with Sarcoidosis and Abnormal RV Function as Defined by Reduction in Magnitude of Peak Longitudinal Free Wall Strain. Data are Summarized Separately for Patients with Lung Disease, Pulmonary Hypertension, and Left Ventricular Sarcoid Involvement Evidenced by Late Gadolinium Enhancement, as Well as Patients with None of the Above Findings (See Text for Detail)

	N	TAPSE (mm)	RV S’ (cm/sec)	RV FAC (%)	Free Wall Strain (%)
Lung disease	16	14 ± 5	7.5 ± 2	25 ± 8	−14.3 ± 3.8
Pulmonary hypertension	8	16 ± 4	7.8 ± 1.7	26 ± 9	−14.1 ± 3.2
LV sarcoid involvement	10	17 ± 2	8.2 ± 1.3	25 ± 10	−14.5 ± 3.5
None of the above	4	16 ± 6	13.3 ± 5.1	22 ± 10	−6.0 ± 11.9*

LV = left ventricular; RV = right ventricular; TAPSE = tricuspid annular plane systolic excursion, FAC = fractional area change, S’ = tissue Doppler tricuspid annular peak systolic velocity.

^*P < 0.02 versus all three other categories.
