BACKGROUND: Left ventricular aneurysm (LVA) is a common complication of acute myocardial infarction. We aimed to investigate the association of the platelet-to-albumin ratio (PAR) with LVA formation in patients with acute ST segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI).
METHODS: A total of 767 consecutive patients with STEMI were prospectively enrolled. Logistic regression analysis and restricted cubic spline (RCS) were used to assess the association between PAR and LVA formation. The predictive ability of PAR and combined variable for LVA formation were assessed using receiver-operating characteristic (ROC) curve.
RESULTS: The prevalence of LVA was 14.1%. Univariable logistic regression analysis revealed that PAR was associated with the risk of LVA at both 1 month [odds ratio (OR) = 4.42, P < 0.001] and 6 months (OR = 4.35, P < 0.001) of follow-up. The predictive value of PAR remained significant even after multivariate logistic regression analysis at 1 month (OR = 3.42, P = 0.004) and 6 months (OR = 4.28, P < 0.001). RCS analysis revealed a nonlinear association between a higher PAR and an increased risk of LVA (nonlinear P < 0.05). In addition, the predictive abilities of PAR for LVA were 0.659. The combination of PAR, hemoglobin, left ventricular ejection fraction, and the use of angiotensin-converting enzym inhibitor/angiotensin receptor blocker significantly enhanced the ability to predict LVA formation (C statistic= 0.887).
CONCLUSION: A higher PAR was significantly associated with an increased risk of LVA formation in patients with acute STEMI who underwent primary PCI.
