Insights
This study found no racial differences in coronary artery disease complexity among ST-elevation myocardial infarction (STEMI) patients receiving percutaneous coronary intervention. Chronic kidney disease, not race, predicted higher disease complexity in STEMI patients.
Area of Science:
- Cardiology
- Interventional Cardiology
- Health Disparities
Background:
- Racial variations in the presentation of ST-segment elevation myocardial infarction (STEMI) have been suggested.
- Understanding these variations is crucial for equitable patient care.
Purpose of the Study:
- To investigate racial variations in the complexity of coronary artery disease (CAD) among patients with STEMI.
- To identify predictors of higher CAD complexity in this patient population.
Main Methods:
- Retrospective analysis of STEMI patients who underwent primary percutaneous coronary intervention (PCI) at a tertiary center (2012-2016).
- Coronary artery disease complexity was assessed using the SYNTAX score.
- Logistic regression analysis was employed to identify predictors of higher SYNTAX scores.
Main Results:
- The study included 260 patients: 201 Whites, 24 African Americans, 19 Hispanics, and 15 of other ethnicities.
- No significant differences in SYNTAX scores were observed across racial groups (p=0.965).
- Chronic kidney disease was identified as the sole significant predictor of higher SYNTAX scores (p=0.026).
Conclusions:
- This study did not find evidence of racial variations in coronary artery disease complexity for STEMI patients.
- Larger-scale studies are warranted to further explore potential racial disparities in STEMI patient populations.
Background:
Racial variations in presentation of patients with ST-segment elevation myocardial infarction (STEMI) have been suggested.
Methods:
This was a retrospective analysis of a tertiary center from 2012 to 2016. We included patients presenting with acute STEMI who received primary percutaneous coronary intervention (PCI). The main outcome was racial variation in the complexity of coronary artery disease assessed by SYNTAX score. We also reported predictors of higher SYNTAX scores in the study population.
Results:
Our final analysis included 260 patients: 201 Whites (77.3%), 24 African Americans-AA (9.2%), 19 Hispanics (7.3%) and 15 were of other ethnicities (5.8%). The mean SYNTAX score was 13.8 ± 7.7. There was no significant difference between Whites, AA, Hispanics and other races in the SYNTAX score (13.8 ± 7.7, 13.4 ± 7.9, 14.5 ± 9 and 13.5 ± 6.6, p = 0.965). Logistic regression analysis identified chronic kidney disease as the only significant predictor of higher SYNTAX score (Coefficient = 3.5, 95%CI:0.41-6.60, p = 0.026), while no significant association was identified between different races and higher SYNTAX score.
Conclusion:
The current study did not identify racial variations in the complexity of coronary artery disease for STEMI patients. Further studies are needed at a larger scale to identify racial variations in STEMI patients.
