Fig 4: Correlation Between Strains, Myoarchitecture, and RV-PA Coupling.

Fig 4:

(A) RV global circumferential (GCS), longitudinal (GLS), and radial (GRS) strains were associated with helical range. (B) RV circumferential and radial strains were associated with RV-PA coupling, measured by TAPSE/RVSP, while longitudinal strain was not. CDF: Fischer rat model; PA: pulmonary artery; PH: pulmonary hypertension; RV: right ventricle; RVSP: right ventricle systolic pressure; SD: Sprague-Dawley rat model; TAPSE: tricuspid annular plane systolic excursion; TAPSE/RVSP: measure of RV-PA coupling. SD: n=5 Control, 5 PH; CDF: n=4 Control, 4 PH. Linear regression model.
