Pulmonary Vasculature and Right Heart Dysfunction in Chronic Obstructive Pulmonay Disease
Pulmonary Vasculature and Right Heart Dysfunction in Chronic Obstructive Pulmonay Disease
The pulmonary vasculopathy and right heart dysfunction in COPD are drawing increasing
 attention these days. Recent researches show that pulmonary vasculopathy and right heart
 dysfunction relate to greater severity in COPD. Applying appropriate modalities for early
 detection of pulmonary vasculopathy and right heart dysfunction is of great importance.
 What's more, the interaction mechanism between pulmonary vasculature, right heart and COPD
 still needs to be further studied. The aim of our study is to develop an assessment system of
 pulmonary vasculopathy and right heart dysfunction in COPD patients and elucidate their
 impact on COPD course and outcome.
