1 One Year Follow-Up Results from AUGMENT-HF: A Multicenter Randomized Controlled Clinical Trial of the Efficacy of Left Ventricular Augmentation with Algisyl-LVR in the Treatment of Heart Failure* Douglas L. Mann, Randall J. Lee, Andrew J.S. Coats, Gheorghe Neagoe, Dinu Dragomir, Enrico Pusineri, Massimo Piredda, Luca Bettari, Bridget-Anne Kirwan, Robert Dowling, Maurizio Volterrani, Scott D. Solomon, Hani N. Sabbah, Andy Hinson, Stefan D. Anker on behalf of the AUGMENT-HF Investigators Disclosures: Scientific Advisory Board - Lone Star Heart, miRagen therapeutics, Lilly Corporation Consultant Bio Control Medical, Cardioxyl, Medtronic Grant Support NIH * These data will be published online in European Journal of Heart Failure following this presentation 2 Therapeutic options are limited for patients with advanced heart failure who become refractory to conventional pharmacological therapies The injection of biomaterials into diseased myocardium has been shown to reduce myofiber stress, LV wall stress, restore LV geometry and improve LV function 1,2 Algisyl is a medical device that consists of an alginate hydrogel that is injected into the midwall of the LV, where it remains as a permanent implant that is intended to reduce LV wall stress and prevent or reverse the progression of HF Results of the AUGMENT-HF 6-month primary endpoint analysis were presented at this meeting in 2014 and published earlier this summer 3 Background 1 Sabbah HN, et. al., JACC Heart Fail. 2013;1(3): Lee RJ, et. al, Int J Cardiol Jul 2;199: Anker, SD, et. al.
