The Association Between Atherogenic Index of Plasma and No-Reflow Phenomenon in Acute Coronary Syndrome.

Abstract

The atherogenic index of plasma (AIP) is a biomarker of plasma atherogenicity. Elevated AIP is linked with adverse cardiac events. We sought to examine the association of admission AIP and no-reflow phenomenon (NRP) in acute coronary syndrome (ACS) patient population treated with percutaneous coronary intervention (PCI). Eight hundred eight-four ACS patients were included to statistical tests retrospectively and classified according to the occurrence of NRP: NRP (-) (n = 662) and NRP (+) (n = 186). AIP levels were calculated through the formula log10 (triglyceride-to-high-density lipoprotein cholesterol ratio). AIP levels were higher in NRP (+) patients compared to NRP (-) group patients. The receiver operating characteristic (ROC) curve analysis for AIP to predict NRP yielded an area under the ROC curve value 0.643 [95% confidence interval (CI): 0.596-0.690, P <.001]. AIP was associated with NRP in univariate logistic regression analysis [Odds Ratio (OR): 2.46; P =.001; CI: 1.44 (lower limit)-4.21 (upper limit)]. However, AIP did not emerge as a significant prognostic factor of NRP in multiple logistic regression analysis [OR: 2.11; P =.422; CI: 0.34 (lower limit)-13.11 (upper limit)]. On the other hand, peak troponin T (log10) was an independent prognostic factor for NRP [OR: 0.13; P <.001; CI: 0.10 (lower limit)-0.37 (upper limit)] occurrence. The AIP level on admission is not a statistically significant prognostic factor of NRP. However, peak troponin T (log10) is an independent prognostic parameter of NRP.
