Impact of an Optimized Omega-3 Formulation on Inflammation and Endothelial Dysfunction in Pulmonary Arterial Hypertension (OMEGA-PAH)
The objective of this research project is to evaluate the biological effects of long-chain omega-3 supplementation, administered in an optimized, high-purity formulation (EPA:DHA 6:1, >95% v/v), as an adjunct to standard-of-care treatment in patients with pulmonary arterial hypertension (PAH).
The expected results are confirmation in humans of our preliminary data, namely a beneficial effect on systemic inflammation and pulmonary endothelial dysfunction in PAH. If our hypothesis is confirmed, omega-3s could constitute a complementary nutritional approach to current PAH therapies, subsequently requiring validation through a larger-scale, randomized, controlled study.

实验性的:PAH Patients Receiving Omega-3
|
The investigational product is an oral nutritional supplement consisting of an optimized omega-3 fatty acid formulation derived from fish oil. Each hard capsule (hydroxypropyl methylcellulose, HPMC) contains 667 mg of combined eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), with a stoichiometric EPA:DHA ratio of 6:1. The product is provided as transparent hard capsules intended for oral administration. Dosage and administration: Participants will receive a total of four capsules per day, administered as two capsules in the morning and two capsules in the evening, taken with meals to improve gastrointestinal tolerance and absorption. The total daily dose of omega-3 fatty acids is approximately 2.7 g. Treatment duration: The intervention will be administered for a total duration of 12 weeks. |
