Usefulness of The C-Reactive Protein/Albumin Ratio for Predicting No-Reflow in ST-elevation myocardial infarction treated with primary percutaneous coronary intervention.

BACKGROUND: The ratio of serum C-reactive protein (CRP) to albumin has been proven to be a more accurate indicator than albumin and CRP levels alone in determining the prognosis of patients with cancer and critical illness. The aim of this study was to determine whether the CRP/albumin ratio (CAR) can be linked to imperfect reperfusion that can worsen the prognosis of ST-elevation myocardial infarction (STEMI) in patients treated with primary percutaneous coronary intervention (pPCI). MATERIALS AND METHODS: A total of 1217 consecutive STEMI patients who achieved epicardial vessel patency with pPCI were recruited to this study. RESULTS: The study population was divided into 2 groups: reflow (n = 874) and no-reflow (NR) (n = 343) groups. The white blood cell count (WBC), neutrophil-to-lymphocyte ratio (NLR) and CAR (0.03 [0.01-0.04] vs 0.06 [0.03-0.12] (P < .001) were significantly higher in the NR group than in the reflow group, and these factors were found to be independent predictors of NR development. The best cut-off value of CAR predicting NR was 0.59 with a sensitivity of 54.7% and specificity of 86.7. The predictive power of CAR surpassed that of CRP, albumin, WBC count and NLR in the receiver operator curve (ROC) curve comparison. CONCLUSION: No-reflow can be predicted by systemic inflammation markers including WBC count, NLR and CAR measured from the blood sample obtained on admission. CAR has a higher clinical value than CRP, albumin level, WBC count and NLR in NR prediction.

Association of serum uric acid levels with SYNTAX score II and long term mortality in the patients with stable angina pectoris who undergo percutaneous coronary interventions due to multivessel and/or unprotected left main disease.

Serum uric acid (SUA) level was shown in various studies to be related to the presence of coronary artery disease and subsequent cardiovascular events. The aim of the present study was to evaluate the association of SUA with SYNTAX score II (SSII) and the long-term prognosis of patients with stable angina pectoris who underwent percutaneous revascularization due to multivessel disease (MVD) and/or unprotected left main disease (UPLMD). Two-hundred and ninety patients with MVD and/or UPLMD who were treated consecutively with percutaneous coronary intervention (PCI) were included in the present study. The study population was divided into high SSII (n: 145; SSII > 32.9) and low SSII (n: 145; SSII ≤ 32.9) according to the median SSII value. The SUA value was significantly higher in the high SSII group than in the low SSII group (5.53 ± 1.95 vs. 6.07 ± 1.88; p = 0.001) and was found to be an independent predictor of high SSII (OR 1.306; 95% CI 1.119-1.525; p = 0,001). Twenty-eight patients (9.7%) died during the long-term follow-up, and SUA and SSII were additionally found to be independent predictors of long-term mortality (HR 1.245, 95% CI 1.046-1.482, p = 0.014; HR 1.042, 95% CI 1.007-1.079, p = 0.018, respectively). In the present study, SUA level was demonstrated to be associated with high SSII and long-term mortality in patients with MVD and/or UPLMD who were treated with PCI.

Assessment of Relationship Between C-Reactive Protein to Albumin Ratio and Coronary Artery Disease Severity in Patients With Acute Coronary Syndrome.

The association of coronary artery disease (CAD) severity with increased C-reactive protein (CRP) and decreased albumin levels has been reported. However, to our knowledge, no study has investigated the usefulness of the CRP to albumin ratio (CAR) in predicting intermediate-high SYNergy between Percutaneous Coronary Intervention with TAXus and cardiac surgery (SYNTAX) score (SS) and high SS II. Consecutive patients (n = 344) treated with percutaneous coronary intervention comprised the study population. The study population was divided into 2 groups according to SS >22 and mean SS II values, respectively. Patients with intermediate-high SS and high SS II had higher CAR than patients with low SS and SS II. History of diabetes mellitus, decreased albumin, lower left ventricular ejection fraction, and elevated CAR (odds ratio [OR]: 1.020; 95% confidence interval [CI], 1.009-1.031; P < .001) were independent predictors of high SS. The presence of hypertension, decreased hemoglobin and albumin levels, and increased CAR (OR: 1.014; 95% CI, 1.004-1.023; P < .001) were independent predictors of SS II. In receiver operating characteristic curve comparison, CAR was superior to CRP and albumin in prediction of intermediate-high SS, but only CRP in prediction of high SS II. The CAR calculated from the admission blood samples could be a useful parameter for predicting CAD severity using SS and SS II.
