Abstract: | We decided to assess the prognostic value of NLRP3 inflammasome level in acute coronary syndrome (ACS) patients and whether it was related to coronary atherosclerotic severity. Study population included one-hundred and twenty-three (123) subjects. Peripheral blood monocyte NLRP3 protein level was correlated with clinical presentation, angiographic characteristics and its scoring systems as well as GRACE and TIMI risk scores. Follow-up for major adverse cardiac events (MACE) was carried out at 180 days. Peripheral blood monocyte NLRP3 was found to be elevated in ACS patients (P < 0.05) and showed positive correlation with GRACE score (r = 0.619), TIMI score (r = 0.580), SYNTAX score (r = 0.550), Clinical SYNTAX score (r = 0.564) and Gensini score (r = 0.516). NLRP3 was also increased with increasing number of vessels, the number of lesions present and the presence bifurcation lesions (P < 0.05). Multivariate Cox regression analysis showed NLRP3 to be an independent predictor of MACE (P = 0.043). Kaplan–Meier analysis and receiver operating characteristic curves for NLRP3 showed good predictive value for MACE. There is a positive correlation of NLRP3 level with severity of coronary atherosclerosis. NLRP3 level is a promising prognostic utility and is efficient in event prediction for MACE. |
