OCT has shown development of pulmonary arterial remodelling in patients with borderline PH and the occurrence of reverse remodelling following effective treatment [ 72 ]. Technological advances in cardiac imaging coupled with exceptional computing power and innovative analytical modelling offer an unprecedented amount of data that can contribute to the search for novel imaging biomarkers. A recently published machine learning-based survival model had incremental prognostic power when compared with conventional parameters to more accurately predict outcomes in PH [ 73 ].
Such computational simulations can illuminate pathophysiological mechanisms of right ventricular failure, risk stratify different PH groups and identify imaging end-points following therapeutic interventions. Numerous potential biomarkers e.
Currently metabolomics emerges as a potentially informative area of systems biology. Currently, however, abnormal responses versus normal responses to abnormal stimuli are indistinguishable and metabolic signatures have only been evaluated in well-defined, homogenous study populations. New research paradigms are necessary to prove their value for early detection and differential diagnosis of PAH in real life.

Abstract A revised diagnostic algorithm provides guidelines for the diagnosis of patients with suspected pulmonary hypertension, both prior to and following referral to expert centres, and includes recommendations for expedited referral of high-risk or complicated patients and patients with confounding comorbidities.
Blood tests and immunology Blood tests are not useful for PH diagnosis, but distinguish some forms of PH and indicate end-organ compromise. Pulmonary function tests and arterial blood gases Pulmonary function tests are addressed in the PH lung disease Task Force article in this issue of the European Respiratory Journal [ 2 ], and should include total lung capacity and diffusing capacity of the lung for carbon monoxide D LCO.
Cardiopulmonary exercise testing Cardiopulmonary exercise testing CPET for diagnostic purposes can be done non-invasively or with haemodynamic testing [ 8 ]. Transthoracic echocardiography The transthoracic echocardiogram TTE remains the most important non-invasive screening tool and right heart catheterisation RHC remains mandatory to establish the diagnosis.
Open in a separate window. TABLE 2 Echocardiographic signs suggesting pulmonary hypertension PH used to assess the probability of PH in addition to tricuspid regurgitation velocity measurement in table 1. Recommendations Genetic counselling of all idiopathic, anorexiant and familial PAH patients and first-generation asymptomatic family members of patients with known genetic mutations.
Recommendations In symptomatic patients and those with heart failure or hepatic arteriovenous malformations, with HHT or family history of HHT, genetic testing and an echocardiogram should be undertaken.
Portopulmonary hypertension The frequency of PH in patients with liver disease varies with disease severity and duration. Recommendations Echocardiographic screening is recommended in all patients with portal hypertension. Congenital heart disease In CHD, PAH can be identified in four distinct subgroups of patients: 1 Eisenmenger syndrome, 2 persistent systemic-to-pulmonary shunts, 3 those with small, coincidental defects, and 4 patients who have undergone defect correction.
Three-dimensional dynamic contrast-enhanced magnetic resonance: lung perfusion Dynamic contrast-enhanced magnetic resonance estimates of perfusion are based on quantification of tissue enhancement at serial time-points after injection of gadolinium and the technique has comparable sensitivity to perfusion scintigraphy for diagnosing CTEPH [ 56 , 57 ]. Functional magnetic resonance imaging: ventilation The ready availability and ease of inhaled oxygen as a contrast medium makes pulmonary magnetic resonance imaging MRI a promising tool for assessing ventilation.
Subclinical right ventricular dysfunction Parametric mapping A review of the magnetic resonance literature found 21 magnetic resonance metrics indicative of PH [ 59 ]. Right ventricular strain Cardiac magnetic resonance-based right ventricular strain imaging evaluates regional myocardial function by measuring the percentage change in myocardial deformation.
Pulmonary artery four-dimensional flow imaging Time-resolved three-dimensional phase-contrast MRI, also known as four-dimensional flow magnetic resonance, visualises and quantifies cardiovascular blood flow. Intravascular ultrasound and optical coherence tomography in PAH Intravascular ultrasound and optical coherence tomography OCT can demonstrate intimal fibrosis, a surrogate marker of pulmonary arterial remodelling that correlates negatively with pulmonary arterial compliance and is associated with unfavourable clinical outcomes during mid-term follow-up [ 71 ].
