The Predictive Role of Indices Indirectly Indicating Hyperlipidemia and Inflammation in Ascending Aortic Aneurysm

Introduction Ascending aortic aneurysm (AAA) is an aortic disease that can progress with serious complications. The roles of hyperlipidemia and inflammation in its etiology are controversial. In this study, we aimed to investigate the predictive value of indices that can indirectly reflect hyperlipidemia and inflammation in patients with AAA. Methods This prospective study included 146 patients diagnosed with AAA and 88 controls. Demographic data, clinical history and laboratory results, including the atherogenic index of plasma (AIP), atherogenic coefficient (AC), pan-immune-inflammation value (PIV), and systemic immune-inflammation index (SII), were collected. Statistical analyses were performed to evaluate the relationships between these indices and the aortic diameter. Results Patients with AAA presented significantly higher PIV levels than controls did (p>0.05). However, no significant differences were observed in the AIP, AC, or SII between the patient and control groups. Furthermore, no significant correlation was found between the aortic diameter and the studied indices (p<0.05). PIV was the only significant parameter with a p-value of 0.026 (AUC: 0.587) according to the ROC analysis. Conclusion These findings suggest that while hyperlipidemia, as measured by the AIP and AC, may not play a direct role in AAA progression, inflammation indicated by PIV could be an important factor. Especially in resource-limited settings, these useful indicators can improve AAA management before the disease progresses to an advanced stage.
