Impact of an Optimized Omega-3 Formulation on Inflammation and Endothelial Dysfunction in Pulmonary Arterial Hypertension

Обзор

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.

Вмешательства

• Пищевая добавка 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 p
