Key result
GLP-1 receptor agonists may reduce the risk of pulmonary hypertension in diabetic patients, associated with an average 30% reduction in pulmonary artery pressure compared to 5% in non-users.
Why the study?
Pulmonary hypertension is an emerging and underrecognized complication of diabetes mellitus linked to adverse cardiopulmonary outcomes.
Do GLP-1 receptor agonists reduce the risk of pulmonary hypertension in patients with diabetes?
Do GLP-1 receptor agonists reduce the risk of pulmonary hypertension in patients with diabetes?
GLP-1 receptor agonists may represent a novel cardiopulmonary intervention to mitigate pulmonary hypertension risk in patients with diabetes.
Supports evaluation of GLP-1RAs for PH risk in diabetes; leaves open confirmation in prospective RCTs.
Background: Pulmonary hypertension (PH) is an emerging and underrecognized complication of diabetes mellitus, linked to adverse cardiopulmonary outcomes. Insulin resistance, inflammation, and endothelial dysfunction contribute to PH pathogenesis. Objective: This review evaluates the emerging role of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in mitigating PH risk among diabetic patients. Methods: We synthesized data from preclinical and clinical studies, including large-scale observational cohorts, investigating GLP-1RAs' effects on pulmonary vasculature and hemodynamics. Results: GLP-1RAs exhibit anti-inflammatory, vasodilatory, and endothelial-protective properties, with associated improvements in pulmonary artery pressure, vascular remodeling, and cardiopulmonary load. A Veterans Affairs cohort and meta-analyses suggest a reduced PH incidence among GLP-1RA users. Conclusion: GLP-1RAs may represent a novel cardiopulmonary intervention in diabetes care. Prospective trials are needed to confirm their protective role against PH and define optimal integration into therapeutic strategies.

Albulushi et al. (2025) conducted a review in Pulmonary hypertension in diabetes. GLP-1 receptor agonists vs. Non-GLP-1 users was evaluated. GLP-1 receptor agonists may reduce the risk of pulmonary hypertension in diabetic patients, associated with an average 30% reduction in pulmonary artery pressure compared to 5% in non-users.
