The soluble urokinase-type plasminogen activator receptor (suPAR) is a new marker for immune activation and inflammation and may provide diagnostic value on top of established biomarkers in patients with suspected acute myocardial infarction (AMI). Here, we evaluate the diagnostic potential of suPAR levels on top of high-sensitivity troponin I (hs-TnI) in a cohort of patients with suspected AMI. A total of 1220 patients presenting to the emergency department with suspected AMI were included, of whom 245 were diagnosed with AMI. Median suPAR levels at admission were elevated in subjects with AMI compared to non-AMI (3.8 ng/mL vs 3.3 ng/mL, p = 0.001). In C-statistics, the area under the curve (AUC) regarding the diagnosis of AMI was low (0.57 at an optimized cut-off of 3.7 ng/mL). Moreover, baseline suPAR levels on top of troponin values at admission and hour 1 reduced the number of patients who were correctly ruled-out as non-AMI, and who were correctly ruled-in as AMI. Our study shows that circulating levels of suPAR on top of high-sensitivity troponin I do not improve the early diagnosis of AMI.

Abstract AIMS Serial measurements of high-sensitivity troponin are used to rule out acute myocardial infarction (AMI) with an assay specific cutoff at the 99th percentile. Here, we evaluated the performance of a single admission troponin with a lower cutoff combined with a low risk electrocardiogram (ECG) to rule out AMI. METHODS Troponin I measured with a high-sensitivity assay (hs-TnI) was determined at admission in 1040 patients presenting with suspected AMI (BACC study). To rule out AMI we calculated the negative predictive value (NPV) utilizing the optimal hs-TnI cutoff combined with a low risk ECG. The results were validated in 3566 patients with suspected AMI [2-h Accelerated Diagnostic Protocol to Assess Patients With Chest Pain Symptoms Using Contemporary Troponins as the Only Biomarker (ADAPT) studies]. Patients were followed for 6 or 12 months. RESULTS 184 of all patients were diagnosed with AMI. An hs-TnI cutoff of 3 ng/L resulted in a NPV of 99.3% (CI 97.3–100.0), ruling out 35% of all non-AMI patients. Adding the information of a low risk ECG resulted in a 100% (CI 97.5–100.0) NPV (28% ruled out). The 2 validation cohorts replicated the high NPV of this approach. The follow-up mortality in the ruled out population was low (0 deaths in BACC and Stenocardia, 1 death in ADAPT). CONCLUSIONS A single hs-TnI measurement on admission combined with a low risk ECG appears to rule out AMI safely without need for serial troponin testing.

Introduction: Cardiac biomarkers have a prominent role in the diagnosis of acute myocardial infarction. Aim: The aim of the authors was to study the diagnostic effectiveness of automated measurement of cardiac biomarkers. Method: Myeloperoxidase, high-sensitivity C-reactive protein, myoglobin, heart-type fatty acid binding protein, creatine kinase, creatine kinase MB, high-sensitivity troponin I and T were measured. Results: The high-sensitivity troponin I was the most effective (area under curve: 0.86; 95% confidence interval: 0.77–0.95; p<0.001) for the diagnosis of acute myocardial infarction. Considering a critical value of 0.35 ng/mL, its sensitivity and specificity were 81%, and 74%, respectively. Combined evaluation of the high-sensitivity troponin T and I, chest pain, and the electrocardiogram gave the best results for separation of acute myocardial infarction from other diseases (correct classification in 62.5% and 98.9% of patients, respectively). Conclusions: Until a more sensitive and specific cardiac biomarker becomes available, the best method for the diagnosis of acute myocardial infarction is to evaluate electrocardiogram and biomarker concentration and to repeat them after 3–6 hours.
