Insights
The atherogenic index of plasma (AIP) did not predict no-reflow phenomenon (NRP) in acute coronary syndrome (ACS) patients. Peak troponin T levels, however, independently predicted NRP in this patient group.
Area of Science:
- Cardiology
- Biomarkers
- Interventional Cardiology
Background:
- The atherogenic index of plasma (AIP) is a key indicator of plasma atherogenicity, with elevated levels associated with increased cardiac event risk.
- The no-reflow phenomenon (NRP) is a critical complication following percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) patients.
- Understanding predictors of NRP is crucial for improving patient outcomes after PCI.
Purpose of the Study:
- To investigate the association between admission atherogenic index of plasma (AIP) and the occurrence of no-reflow phenomenon (NRP) in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI).
Main Methods:
- A retrospective analysis was conducted on 884 ACS patients, categorized into NRP (-) (n=662) and NRP (+) (n=186) groups.
- Atherogenic index of plasma (AIP) was calculated using the formula: log10 (triglyceride/high-density lipoprotein cholesterol ratio).
- Statistical analyses included receiver operating characteristic (ROC) curve analysis and logistic regression to assess the prognostic value of AIP and peak troponin T for NRP.
Main Results:
- Patients with NRP exhibited higher admission AIP levels compared to those without NRP.
- Univariate analysis showed AIP was associated with NRP (OR: 2.46, P=.001), but this association did not hold in multivariate analysis (OR: 2.11, P=.422).
- Peak troponin T (log10) emerged as an independent prognostic factor for NRP (OR: 0.13, P<.001).
Conclusions:
- Admission atherogenic index of plasma (AIP) is not a statistically significant predictor of no-reflow phenomenon (NRP) in ACS patients treated with PCI.
- Peak troponin T (log10) is identified as an independent prognostic parameter for NRP in this population.
- These findings highlight the importance of troponin T levels in predicting adverse outcomes post-PCI in ACS patients.
Background:
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).
Methods:
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).
Results:
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.
Conclusion:
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.
