Insights
Red cell distribution width (RDW) is linked to coronary artery ectasia (CAE). Higher RDW independently predicts the presence and severity of isolated CAE, suggesting a potential inflammatory connection.
Area of Science:
- Cardiology
- Hematology
- Inflammation Research
Background:
- Red cell distribution width (RDW) is a hematologic index associated with adverse outcomes in cardiac conditions.
- Isolated coronary artery ectasia (CAE) is a coronary anatomy abnormality that can lead to myocardial ischemia.
- Both RDW elevation and CAE are potentially linked to underlying inflammatory processes.
Purpose of the Study:
- To investigate the association between RDW and the presence and severity of isolated CAE.
- To determine if RDW is an independent predictor of isolated CAE.
Main Methods:
- Retrospective evaluation of 2345 patients undergoing coronary angiography.
- Inclusion of 75 patients with isolated CAE and 96 controls with normal coronary arteries.
- RDW measurement from automated complete blood count and CAE severity assessment using the Markis classification.
Main Results:
- Red cell distribution width (RDW) was found to be significantly associated with isolated CAE.
- Elevated RDW independently predicted both the presence and severity of isolated CAE.
- The study identified RDW as a potential biomarker for CAE.
Conclusions:
- Red cell distribution width (RDW) is associated with the presence of isolated coronary artery ectasia (CAE).
- RDW is also an independent predictor of the severity of isolated CAE.
- RDW may serve as a useful indicator in patients with or at risk for CAE.
Abstract:
Red cell distribution width (RDW) is an index that has been shown to be an independent correlate of adverse outcomes in some cardiac conditions. Isolated coronary artery ectasia (CAE) is an abnormality of the coronary anatomy and can cause ischemia. We hypothesized that increased RDW would be associated with isolated CAE because both are associated with inflammation. In this study, 2345 patients who received coronary angiography were retrospectively evaluated. After exclusion, 75 patients with isolated CAE and 96 consecutive patients with normal coronary were included in the study. The severity of isolated CAE was determined according to the Markis classification. Baseline RDW was measured as part of the automated complete blood count. Red cell distribution width was observed to be an independent predictor of both presence and severity of isolated CAE. In conclusion, RDW is associated with both the presence and severity of isolated CAE.
