Researchers looked at whether cigarette smoking affected the diagnosis and disease progression of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). They found that smoking tended to delay the diagnosis of PAH but not CTEPH. They also found that male smokers with PAH fared worse than female smokers. Read the Pulmonology article

This study tried to identify new environmental triggers or genetic causes in heritable pulmonary arterial hypertension. They found several potential genes for further exploration, but they also found consistent toxin exposure on one of the families they were investigating. They conclude that environmental triggers should also be investigated in heritable PAH. Read the Scientific Reports article

This study identified factors associated with a delayed diagnosis of PAH and found that earlier diagnosis (<6 months) and treatment initiation were associated with significantly improved survival. More early diagnosis patients saw a pulmonologist before another provider. Read the Pulmonary Circulation article
