Our journey continues

In the 6th Century BCE the Chinese philosopher Laozi (Lao Tzu) wrote in the Daodejing (Tao Te Ching), “A journey of a thousand miles begins with a single step.” The first step of the journey upon which Pulmonary Circulation is now embarked was taken this past March, with the publication of Volume 1, Number 1, and the present issue is our second step. Where will this journey lead? Inevitably, as authors share their work and discoveries with readers, the journey will lead to advances in our field, as this new journal becomes the primary medium of communication between physicians and researchers in the field of pulmonary vascular diseases worldwide. In particular, we hope, our journey will contribute to easing the enormous burden of pulmonary vascular disease in the so-called developing world. Although the research output in the form of publications from these regions is far less compared to elsewhere, we will endeavor to bring high-quality research outputs from these regions to the attention of the so-called developed world.
