Risk Factors for No-Reflow in Patients with ST-Elevation Myocardial Infarction Who Underwent Percutaneous Coronary...

Area of Science:

• Cardiology
• Biomedical Science

Background:

• ST-elevation myocardial infarction (STEMI) is a critical condition requiring timely reperfusion.
• Percutaneous coronary intervention (PCI) is the preferred treatment, but the no-reflow phenomenon can limit its effectiveness.
• Identifying predictors of no-reflow is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the independent risk factors associated with the no-reflow phenomenon in patients undergoing primary PCI for STEMI.
• To provide insights into factors that may predict suboptimal reperfusion in STEMI patients.

Main Methods:

• Retrospective case-control study analyzing data from 902 patients treated with primary PCI within 12 hours of STEMI onset.
• Comparison of patient characteristics between reflow and no-reflow groups.
• Multivariable analysis to identify independent predictors of no-reflow.

Main Results:

• No significant differences in basic characteristics were observed between reflow and no-reflow groups, except for specific variables.
• Independent risk factors for no-reflow included elevated high-sensitivity C-reactive protein/prealbumin (hsCRP/PAB) ratio, increased neutrophil count, higher plasma glucose levels, diabetes mellitus, and Killip classification >1.
• Intraoperative use of intraaortic balloon pump (IABP) and aspiration thrombectomy were also significantly associated with no-reflow.

Conclusions:

• hsCRP/PAB ratio, neutrophil count, plasma glucose levels, diabetes mellitus, Killip classification, intraoperative IABP use, and aspiration thrombectomy are independent risk factors for no-reflow in STEMI patients.
• These findings highlight potential targets for risk stratification and management to improve PCI outcomes in STEMI.
