(>3 WU or 240 dyn/s/cm<span class="elsevierStyleSup">−3</span>) At that meeting the definition of exercise PH was further revised, taking into account the variations in CO and PCWP. The diagnosis of exercise PH was proposed if mPAP exceeded 30 mmHg provided that CO was <10 bpm, which means that total pulmonary vascular resistances must be above 3 WU.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">22</span></a></p><p id="par0145" class="elsevierStylePara elsevierViewall">Many factors affect the behaviour of mPAP during exercise, making it difficult to define the normal range and, therefore, the pathological threshold. mPAP increases with age and with CO elevation. Healthy athletes can reach very high COs with exercise and show significant mPAP elevations, above values considered normal. It is also difficult to measure PCWP correctly due to the patient's movements during exercise and respiratory variations. In addition, PCWP is physiologically elevated during exercise and the normal range in healthy patients has not been established, although a significant elevation is known in patients with left ventricular diastolic dysfunction. Finally, PVRs are calculated using the formula PVR = (mPAP−PCWP)/CO, with a correct measurement of PCWP being essential to determine the aetiology responsible for the increase in mPAP during exercise. It is very difficult to discriminate between pulmonary hypertension secondary to left heart disease, especially in heart failure with preserved ejection fraction,<a class="elsevierStyleCrossRef" href="#bib0125"><span class="elsevierStyleSup">25</span></a> and exercise PH due to pulmonary vascular disease by exercise catheterization.

The symptoms of PH initially manifest with exercise, with the patient being asymptomatic at rest. To detect the presence of pulmonary vasculopathy at earlier stages, CPET is proposed as a screening test rather than a resting ECG.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">26</span></a></p><p id="par0155" class="elsevierStylePara elsevierViewall">The ability of CPET in the non-invasive detection of PH in patients with scleroderma has been previously published<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">16</span></a>; however, in our study we compared for the first time the early diagnosis sensitivity of the DETECT algorithm (current established screening method) versus CPET in patients diagnosed with scleroderma; in contrast to the work of Santaniello et al.<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">27</span></a> and Luo et al.,<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">28</span></a> the presence of PH was assessed both at rest and during exercise.</p><p id="par0160" class="elsevierStylePara elsevierViewall">The results of this study suggest that CPET, a non-invasive and safe test, detects initial involvement of the pulmonary vasculature during exercise with greater sensitivity than current established screening (100 vs. 70%), while maintaining a high specificity (90%). This is because both the echocardiogram recommended by clinical guidelines and the DETECT protocol (whose second step includes such echocardiogram) are performed at rest. CPET demonstrates greater diagnostic yield and would be very useful to incorporate into the diagnostic algorithm.</p><p id="par0165" class="elsevierStylePara elsevierViewall">Exercise heart catheterization is safe and feasible and is able to unmask the presence of pulmonary vascular damage earlier in at-risk populations, which would accelerate diagnosis and initiation of treatment, improving the prognosis of the disease. At present there is no consensus definition of exercise PH, but it would be highly beneficial if increased research and the use of exercise heart catheterisation could lead to a consensus definition.
