The external validation cohort included 81 postcapillary PH patients and 66 precapillary PH patients. Using a predefined cutoff of 104, the OPTICS score had 100% specificity for postcapillary PH (sensitivity, 22%). In addition, we investigated whether a high probability of heart failure with preserved ejection fraction, assessed by the H2FPEF score (obesity, atrial fibrillation, age 60 yrs, ≥2 antihypertensives, E/e' 9, and pulmonary artery systolic pressure by echo 35 mmHg), similarly predicted the presence of elevat
