Cardiac MRI-derived ventricular-pulmonary arterial coupling predicts outcomes in connective tissue disease-associated pulmonary arterial hypertension patients.

LV function showed no intergroup differences.Despite a significant difference in the total LGE score between patients with and without clinical deterioration events(p = 0.013), it did not reach statistical significance in the univariable Cox regression analysis.A lower mv PA and PA RAC correlated with higher clinical deterioration events ( Table 2 ).
