Abstract

Objective: To investigate the clinical effects of NRLP1 expression in patients with ST-segment elevation myocardial infarction (STEMI) combined with arrhythmia.

Methods: We enrolled 231 patients with STEMI in the first hospital of Quanzhou affiliated to Fujian Medical University from January 2019 to December 2020 to the observational group and 230 healthy individuals as the control group. We divided patients with STEMI into a malignant ventricular arrhythmia (MVA) group (n=36) and non-MVA(NMVA) group (n=195) depending on whether the individuals had experienced an episode of MVA within 48 hours after PCI. We recorded general variables such as age, gender, history of smoking, hypertension, of diabetes, hyperlipidemia, left ventricular ejection fraction (LVEF), Gensini score, and mortality. Moreover, we determined NLRP1, IL-1β, TNF-α, high-sensitivity C-reactive protein (hs-CRP), N-terminal pro-brain natriuretic peptide (NT-pro-BNP), cardiac troponin-1 (cTnI), and creatine kinase isoenzyme (CK-MB) in peripheral blood by ELISA.

Results: We found significant differences in LVEF, Gensini scores, smoking history, and mortality between the MVA and NMVA groups. The mean NLRP1 expression was highest in the MVA group, which was positively correlated with the levels of IL-1β, TNF-α, hs-CRP, NT-pro-BNP, cTnI and CK-MB. The expression of NLRP1 was associated with the smoking history, the LVEF value, the Gensini score, the MVA incidence and the mortality. Patients with higher NLRP1 expression levels had a higher MACE incidence and worse overall survivals within one year.

Conclusion: The NLRP1 pathway is associated with the presence of arrhythmias after PCI treatments, and the NLRP1 expression level may be useful as a predictor of arrhythmia in patients with STEMI.
