| Outline of Final Research Achievements |
An important pathogenic mechanism in the development of idiopathic pulmonary arterial hypertension is hypothesized to be a cancer-like cellular proliferation independent of hemodynamics. However, because the vascular lesions are inseparably coupled with hemodynamic stress, the fate of the lesions is unknown when hemodynamic stress is eliminated.
Our results indicate that hemodynamic stress is prerequisite to the development and progression of occlusive neointimal lesions in this rat model of severe pulmonary hypertension. We conclude that perivascular inflammation and occlusive neointimal arteriopathy are driven by hemodynamic stress.
