#: The test was considered positive only if both criteria mPAPmax >30 mmHg and TPRmax >3 WU were satisfied. mPAPmax: mean pulmonary artery at maximal exercise; TPRmax: total pulmonary resistance at maximal exercise; NPV: negative predictive value; PPV: positive predictive value; PVD: pulmonary vascular disease; LHD: left heart disease.
