Introduction: Non-ST-elevation (NSTE) acute coronary syndrome (ACS) is a common and polymorphic condition. Predicting significant coronary artery disease (CAD) is sometimes difficult. The objective of this study was to identify predictors of CAD severity in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). Patients and Methods: We prospectively evaluated 296 patients with NSTE-ACS who underwent a coronary angiography. Significant CAD was defined as ≥70% stenosis in at least one major coronary artery. Clinical characteristics in the hospital for 30 days and one-year outcomes were prospectively noted and a multivariate analysis was performed. Results: The study included 296 NSTE-ACS patients. The mean age of the patients was 62.1 ± 12.6 years old while 58.1% of the patients were males. A multivariable analysis for the significant CAD predictors is shown (Figure 1), representing current smoking (ORa = 4.4; 95% confidence interval [CI] = 1.5–13.0, p = 0.007), a diabetic under insulin (Ora = 6.4; 95% [CI] = 2.4–17.4, p < 10-3), typical angina (ORa = 5.4; 95% [CI] = 1.7–16.8, p = 0.003), persistent angina (ORa = 5.3; 95% [CI] = 1.3–21.8, p = 0.019), recurrence of angina (ORa = 8.9; 95% [CI] = 1.5–51.4; p = 0.015), down sloping ST depression (ORa = 6.1; 95% [CI] = 2.4–15.3, p < 10-3), positive troponin (ORa = 4.2; 95% [CI] = 1.9–9.2, p < 10-3), kinetic disorder > 2 segments (ORa = 2.5; 95% [CI] = 1.1–6.0, p = 0.049), intima-media thickness (IMT) > 0.8 mm (ORa = 5.2; 95% [CI] = 2.3–12.1, p < 10-3). Conclusion: In this study, the severity of CAD was predicted by parameters such as typical or recurrent angina pectoris, current smoking, diabetic on insulin, down sloping ST depression, elevation of troponin, kinetic anomaly in more than two segments and the IMT greater than 0.8 mm.

Previous studies showed that fibrinogen-to-albumin ratio (FAR) regarded as a novel inflammatory and thrombotic biomarker was the risk factor for coronary artery disease (CAD). In this study, we sought to evaluate the relationship between FAR and severity of CAD, long-term prognosis in non-ST elevation acute coronary syndrome (NSTE-ACS) patients firstly implanted with drug-eluting stent (DES). A total of 1138 consecutive NSTE-ACS patients firstly implanted with DES from January 2017 to December 2018 were recruited in this study. Patients were divided into tertiles according to FAR levels (Group 1: ≤8.715%; Group 2: 8.715%~10.481%; and Group 3: >10.481%). The severity of CAD was evaluated using the Gensini Score (GS). The endpoints were major adverse cardiovascular events (MACE), including all-cause mortality, myocardial reinfarction, and target vessel revascularization (TVR). Positive correlation was detected by Spearman’s rank correlation coefficient analysis between FAR and GS (r=0.170, P<0.001). On multivariate logistic analysis, FAR was an independent predictor of severe CAD (OR: 1.060; 95% CI: 1.005~1.118; P<0.05). Multivariate Cox regression analysis indicated that FAR was an independent prognostic factor for MACE at 30 days, 6 months, and 1 year after DES implantation (HR: 1.095; 95% CI: 1.011~1.186; P=0.025. HR: 1.076; 95% CI: 1.009~1.147; P=0.026. HR: 1.080; 95% CI: 1.022~1.141; P=0.006). Furthermore, adding FAR to the model of established risk factors, the C-statistic increased from 0.706 to 0.720, 0.650 to 0.668, and 0.611 to 0.632, respectively. And the models had incremental prognostic value for MACE, especially for 1-year MACE (NRI: 13.6% improvement, P=0.044; IDI: 0.6% improvement, P=0.042). In conclusion, FAR was associated independently with the severity of CAD and prognosis, helping to improve risk stratification in NSTE-ACS patients firstly implanted with DES.
