Continuous variables are expressed as mean±SD; nominal variables are expressed as numbers. sPAP indicates systolic pulmonary arterial pressure.

*

P value for comparisons between statin group and nonstatin group.

†

sPAP was available in 224 patients (200 patients in the nonstatin group and 24 patients in the statin group).
