In the prospective, international InSHAPE II study, a non-invasive strategy for early identification of chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary embolism (PE) proved both accurate and cost-saving [1]. The diagnostic delay of CTEPH after acute PE is over 1 year and associated with increased mortality. Dr Gudula Boon (Leiden University Medical Center, the Netherlands) and her colleagues developed a non-invasive screening strategy comprising a 'CTEPH prediction score' and 'CTEPH rule-out criteria' aimed at diagnosing CTEPH earlier and limiting the number of required echocardiograms. “Six predictors [e.g. unprovoked PE, hypothyroidism, and diagnostic delay >2 weeks] have been identified that are highly probable for CTEPH and we included them in our score,” Dr Boon explained. The CTEPH ru...
