Figure 1. Algorithm for Detection of PAH in Patients with Scleroderma.

Figure 1

Proposed algorithm for performance of routine clinical tests in patients with scleroderma which may allow early detection of pulmonary arterial hypertension or other causes of functional impairment such as cardiac dysfunction (e.g., left ventricular dysfunction) or parenchymal disease (e.g., IPF).
