Males with pulmonary arterial hypertension (PAH) have more proinflammatory macrophages — a type of immune cell — in the lungs than do females with the disease, a study suggests. Researchers identified 56 genes showing differing activity in macrophages taken from men and women with PAH, with this altered activity…

Adults with severe pulmonary arterial hypertension (PAH) awaiting lung transplants can safely participate in pulmonary rehabilitation and maintain or improve exercise capacity, a study found. Pulmonary rehabilitation led to modest improvements in measures of aerobic training and in muscle training volumes with no major adverse events. However, participation in…

Long-term oxygen improves exercise capacity in people with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH), a study suggests. Twelve weeks of supplemental oxygen led to a significant and clinically relevant improvements in exercise capacity, as assessed with the six-minute walking distance test (6MWD), by 42…
