E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
F373280 is a new therapy based on DHA delivery (pro-drug) developed for the maintenance of sinus rhythm after electrical cardioversion in persistent atrial fibrillation (AF) patients with chronic heart failure. The results of a pharmacological study performed in animals evidenced that DHA reduces the duration of Atrial Fibrillation (AF) induced by burst pacing. |
