Platelet to lymphocyte ratio in acute aortic dissection

Area of Science:

• Cardiovascular Medicine
• Hematology
• Inflammatory Biomarkers

Background:

• Inflammation is crucial in acute aortic dissection (AAD) development and progression.
• Novel inflammatory indices from complete blood count (CBC) may indicate AAD risk.
• This study investigates platelet-lymphocyte ratio (PLR), red cell distribution width (RDW), and RDW/platelet ratio (RPR) in AAD.

Purpose of the Study:

• To evaluate the diagnostic utility of PLR, RDW, and RPR in patients with AAD.
• To compare these inflammatory indices between AAD patients and control groups.
• To explore the correlation of PLR with neutrophil-lymphocyte ratio (NLR).

Main Methods:

• A study involving 120 patients with AAD type I, 121 with ascending aortic aneurysms, and 121 controls.
• Patients were grouped based on AAD diagnosis, aortic aneurysm, and healthy controls, matched for age and sex.
• Statistical analysis was performed to compare inflammatory indices and assess correlations.

Main Results:

• PLR was significantly elevated in AAD patients compared to both aneurysm and control groups (P < .001).
• A strong correlation was observed between PLR and NLR across all groups (P < .001).
• RPR remained significantly higher in AAD patients post-hemoglobin adjustment (P < .001), with PLR showing 86% specificity for AAD prediction.

Conclusions:

• CBC-derived indices, including PLR and RPR, show potential for diagnosing AAD.
• Further research is needed to determine if these inflammatory markers can predict prognosis in AAD patients.
