Insights
A high De Ritis ratio (AST/ALT) is linked to poor myocardial reperfusion in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (pPCI). This easily measured ratio may identify high-risk individuals.
Area of Science:
- Cardiology
- Biochemistry
- Medical Diagnostics
Background:
- Successful myocardial reperfusion is critical post-primary percutaneous coronary intervention (pPCI) for ST-segment elevation myocardial infarction (STEMI).
- The De Ritis ratio (AST/ALT) is a biochemical marker with potential prognostic value.
Purpose of the Study:
- To investigate the association between the De Ritis ratio and myocardial reperfusion in STEMI patients treated with pPCI.
- To determine if the De Ritis ratio can predict impaired reperfusion after pPCI.
Main Methods:
- Retrospective analysis of 1236 STEMI patients undergoing pPCI.
- Patients categorized into low and high De Ritis ratio groups based on the median (.921).
- Myocardial reperfusion assessed by ST-segment resolution (STR); <70% STR defined as poor reperfusion.
Main Results:
- A high De Ritis ratio was significantly associated with poor myocardial reperfusion (OR 10.9, P < .001).
- Stent size (OR 1.45, P = .01) and neutrophil-to-lymphocyte ratio (OR 1.22, P = .03) also correlated with poor reperfusion.
- The De Ritis ratio demonstrated a strong predictive value for impaired myocardial perfusion.
Conclusions:
- Elevated De Ritis ratio is a significant predictor of poor myocardial reperfusion in STEMI patients post-pPCI.
- The De Ritis ratio, being readily available, can aid in identifying STEMI patients at higher risk for inadequate reperfusion.
- This marker offers a simple tool for risk stratification in clinical practice.
Abstract:
Successful reperfusion of myocardial tissue is the goal of primary percutaneous coronary intervention (pPCI) in patients with ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association between the De Ritis ratio (AST/ALT) and myocardial reperfusion in patients with STEMI who underwent pPCI. We retrospectively investigated 1236 consecutive patients who were hospitalized for STEMI and underwent pPCI. ST-segment resolution (STR) was defined as the return of the deviated ST-segment to baseline; poor myocardial reperfusion was defined as <70% STR. Patients were divided into 2 groups according to the median De Ritis ratio (.921); 618 patients (50%) were assigned to the De Ritis low group while 618 patients (50%) were assigned to the De Ritis high group. Stent size, neutrophil-to lymphocyte ratio (NLR), and the De Ritis ratio found to be associated with poor myocardial reperfusion (Odds ratio (OR) 1.45, 95% CI 1.07-1.98, P = .01, OR 1.22, 95% CI 1.01-1.48, P = .03 and OR 10.9, 95% CI 7.9-15, P < .001, respectively). A high De Ritis ratio was associated with poor myocardial reperfusion in STEMI patients who underwent pPCI. As an easily obtainable test in clinical practice, the De Ritis ratio may help identify patients at major risk for impaired myocardial perfusion.
