Objective:

To systematically assess the prognostic significance of the systemic inflammatory response index (SIRI) in patients with acute coronary syndrome (ACS) undergoing primary percutaneous coronary intervention (PCI), highlighting its potential impact on clinical decision-making.

Key Findings:
  • SIRI is a promising biomarker for predicting prognosis in CAD after PCI, with elevated levels correlating to increased risk of all-cause mortality and MACE.
  • Quantitative analysis shows that elevated SIRI levels significantly increase the risk of adverse outcomes.
  • SIRI allows for better risk stratification and individualized treatment plans for post-PCI patients.
Interpretation:

SIRI serves as a valuable prognostic tool in assessing the risk of adverse outcomes in ACS patients post-PCI, potentially guiding clinical decision-making and improving patient management.

Limitations:
  • Lack of consensus on the clinical utility of SIRI across studies, with variability in study designs and populations affecting generalizability.
  • Potential biases in study selection and data extraction processes.
Conclusion:

SIRI may enhance risk stratification and management of patients with ACS undergoing PCI, warranting further research to establish its clinical application, particularly in diverse populations.
