Systemic inflammation response index is associated MACE in patients with NSTEMI

Area of Science:

• Cardiology
• Inflammation Research
• Biomarker Discovery

Background:

• Non-ST segment elevation myocardial infarction (NSTEMI) is a significant cardiovascular concern.
• The systemic inflammation response index (SIRI) is an emerging inflammatory marker with potential relevance in cardiovascular diseases.
• The specific association between SIRI and NSTEMI outcomes is not well-established.

Purpose of the Study:

• To investigate the correlation between SIRI and major adverse cardiovascular events (MACE) in NSTEMI patients.
• To determine if SIRI can serve as an independent predictor of MACE in this population.
• To explore the prognostic value of SIRI in NSTEMI management.

Main Methods:

• A cohort of 935 NSTEMI patients undergoing percutaneous intervention was analyzed.
• MACE was defined as all-cause death, malignant arrhythmia, or unplanned percutaneous coronary intervention.
• SIRI was calculated as (neutrophil count * monocyte count) / lymphocyte count; ROC curve analysis determined the MACE prediction cut-off.

Main Results:

• SIRI was found to be an independent predictor of MACE in NSTEMI patients.
• A SIRI cut-off of 2.3 demonstrated 68% sensitivity and 76% specificity for MACE detection.
• Mean SIRI levels differed significantly between patients with and without MACE.

Conclusions:

• SIRI is a robust independent predictor of MACE in the context of NSTEMI.
• SIRI holds potential as a prognostic indicator for adverse cardiovascular events in NSTEMI patients.
• These findings contribute to understanding NSTEMI pathophysiology and may guide clinical management.
