Effect of stress-induced hyperglycaemia on clinical outcome in paitients with acute ST-segment elevation myocardial infarction undergoing percutaneous coronary intervention
Impact of Stress-Induced Hyperglycemia on Clinical Outcomes in STEMI Patients
Overview
This study investigates the impact of stress hyperglycemia (SHG) on clinical outcomes in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). SHG is identified as a significant independent risk factor for in-hospital mortality and long-term adverse outcomes, emphasizing the need for early risk stratification.
Background
Stress hyperglycemia is a transient glycemic disturbance that occurs during acute stress, such as myocardial infarction. Its prognostic significance in STEMI patients undergoing PCI is not fully understood, despite evidence linking it to worse outcomes. Understanding SHG's role can enhance risk stratification and management strategies in this high-risk population.

14.9%
26.0%
Non-SHG (n=319)

Key Findings
SHG is associated with significantly higher in-hospital all-cause mortality (13.4% vs. 2.19%, P < 0.001).
Multivariate analysis identifies SHG as the strongest independent risk factor for in-hospital mortality (OR = 4.68).
At one year, SHG patients exhibit higher mortality (14.9% vs. 3.76%) and heart failure incidence (26.0% vs. 12.23%).
Long-term mortality is primarily influenced by Killip classification and coronary artery disease severity.
SHG should be incorporated into early risk stratification for STEMI patients.
Clinical Implications
Clinicians should recognize SHG as a critical factor in assessing the prognosis of STEMI patients undergoing PCI. Early identification of SHG can facilitate tailored management strategies to improve outcomes in this vulnerable population.
Conclusion
The findings underscore the importance of monitoring stress hyperglycemia in STEMI patients, as it significantly impacts both short- and long-term clinical outcomes. Further research is warranted to elucidate the mechanisms underlying this association.
Researchers found that patients with higher waist circumference and lower grip strength had the greatest risk for developing type 2 diabetes during long-term follow-up.
