Insights
Elevated galectin-3 levels in ST-segment elevation myocardial infarction (STEMI) patients predict poor 30-day outcomes. High galectin-3 is a strong predictor of major adverse clinical outcomes after primary percutaneous coronary intervention.
Area of Science:
- Cardiology
- Biomarkers
- Clinical Research
Background:
- ST-segment elevation myocardial infarction (STEMI) is a critical cardiovascular event.
- Identifying reliable prognostic biomarkers is crucial for managing STEMI patients.
- Galectin-3 is a protein with potential roles in cardiac remodeling and inflammation.
Purpose of the Study:
- To investigate the association between circulating galectin-3 levels and 30-day prognostic outcomes.
- To determine if galectin-3 can predict major adverse clinical outcomes (MACO) in STEMI patients undergoing primary percutaneous coronary intervention (PCI).
Main Methods:
- Blood samples were collected from 196 STEMI patients treated with primary PCI and 30 healthy controls.
- Circulating galectin-3 levels were measured using enzyme-linked immunosorbent assay (ELISA).
- Statistical analyses, including multivariate analysis, were performed to assess the predictive value of galectin-3.
Main Results:
- STEMI patients exhibited significantly higher galectin-3 levels compared to healthy controls (p<0.001).
- Higher galectin-3 levels (≥7.67 ng/mL) were associated with older age, lower ejection fraction, and increased comorbidities.
- Elevated galectin-3 was a strong independent predictor of 30-day MACO, including advanced congestive heart failure and mortality (p<0.0001).
Conclusions:
- Circulating galectin-3 is significantly elevated in STEMI patients.
- High galectin-3 levels are associated with adverse clinical characteristics and outcomes.
- Galectin-3 shows promise as a valuable biomarker for predicting 30-day MACO in STEMI patients undergoing primary PCI.
Aim:
This study investigated the impact of the circulating galectin-3 level on the 30-day prognostic outcome in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).
Methods:
From May 2009 to March 2011, blood samples for assessment of the circulating galectin-3 level were collected from 196 consecutive STEMI patients treated by primary PCI and from 30 healthy volunteers.
Results:
The galectin-3 level was determined using ELISA. Our results demonstrated that the circulating level of galectin-3 was significantly higher in STEMI patients than in healthy control subjects (p<0.001). As compared with patients with galectin-3 <7.67 ng/mL, patients with galectin-3 ≥7.67 ng/mL were significantly older, had significantly lower left ventricular ejection fraction and significantly higher frequency of elevated white blood cell count, advanced Killip score (defined as ≥ score 3), congestive heart failure (defined as ≥ New York Heart Association Functional Class III), respiratory failure, unstable hemodynamics requiring a mechanical ventilator and intra-aortic balloon pump support, multiple vessel diseases and 30-day mortality (all p<0.04). Furthermore, multivariate analysis showed that elevated circulating level of galectin-3 was the strongest independent predictor of the combined 30-day major adverse clinical outcome (MACO) (defined as advanced CHF or 30-day mortality) (p<0.0001).
Conclusion:
A high circulating galectin-3 level may serve as a useful biomarker for predicting 30-day MACO in patients with STEMI undergoing primary PCI.
