The C-reactive protein\u2013albumin\u2013lymphocyte index, neutrophil-to-lymphocyte ratio, C-reactive protein, and systemic immune\u2013inflammation index were calculated from admission laboratories. Severe acute coronary syndrome was defined as ST-elevation myocardial infarction; mild acute coronary syndrome included non\u2013ST-elevation myocardial infarction and unstable angina. Multivariable logistic regression was used to identify the predictors of severe acute coronary syndrome. Discriminative performance was assessed using receiver operating characteristic analysis with DeLong\u2019s test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Lower C-reactive protein\u2013albumin\u2013lymphocyte index values were significantly associated with severe acute coronary syndrome (adjusted odds ratio: 0.91; 95% confidence interval: 0.86\u20130.95; p\u2009&lt;\u20090.001) after adjustment for conventional risk factors. In receiver operating characteristic analysis, the C-reactive protein\u2013albumin\u2013lymphocyte index (area under the curve: 0.696; 95% confidence interval: 0.658\u20130.735) outperformed C-reactive protein (area under the curve: 0.599), neutrophil-to-lymphocyte ratio (area under the curve: 0.624), and systemic immune\u2013inflammation index (area under the curve: 0.560) in discriminating severe from mild acute coronary syndrome (all p\u2009\u2264\u20090.001 for pairwise comparisons).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The C-reactive protein\u2013albumin\u2013lymphocyte index may help identify patients with more severe acute coronary syndrome and offers superior discrimination compared with established inflammatory and nutritional markers.
