Inflammation has been demonstrated to negatively impact patients in the peri-ACS period. This narrative review outlines the inflammatory response in ACS, highlighting the role of the NLRP3 inflammasome pathway following acute plaque rupture and coronary intervention and its potential as a pharmacologic target. RECENT: nvestigators have leveraged medications targeting the NLRP3 inflammasome currently used for other inflammatory pathologies, including colchicine, tocilizumab and anakinra. Investigation into these drugs in the peri-ACS period has yielded varying results, with the most encouraging findings in ACS patients treated with tocilizumab. More conflicting data exists for the role of colchicine and anakinra, with many studies limited in their power to detect clinical outcomes and heterogeneity in their patient populations and endpoints. Despite conflicting data, the NLRP3 remains an attractive therapeutic target in the peri-ACS period. Further investigation is required to prove benefit and safety with large clinical trials adequately powered for clinical outcomes.
