Abstract Background Sepsis is heterogenous with regard to factors such as causal microorganism, patient predisposition, co-morbidity and response to therapy, a key element and unifying feature is the manifestation of cardiovascular dysfunction. Elevated concentrations of cardiac troponin I (cTnI) are frequently observed in patients with severe sepsis and septic shock even in the absence of an acute coronary syndrome (ACS). Objective To evaluate the prognostic value of (cTnI) with echocardiography assessment in septic patients. Patients and Methods This study was conducted at the intensive care units of Ain Shams university hospitals. 20 patients of both sexes with age ranging from 18 to 70 years diagnosed with sepsis admitted to Intensive care unit were included in prospective observational study. Results Baseline cTnI had a significant positive correlation with follow up troponine (p = 0.0016). Baseline EF had a significant negative correlation with follow up troponine (p = 0.036). Using ROC-curve analysis, troponin level at a cutoff point (>1.9) predicted patients with mortality, with good (87%) accuracy, sensitivity= 90% and specificity= 90% (p < 0.01). Conclusion Elevated concentrations of cardiac troponin I (cTnI) are frequently observed in patients with sepsis and septic shock even in the absence of an acute coronary syndrome.

Baseline Characteristics

Background. Elevated cardiac troponin in acute stroke in absence of acute coronary syndrome (ACS) has unclear long-term outcomes.Methods. Retrospective analysis of 566 patients admitted to Temple University Hospital from 2008 to 2010 for acute stroke was performed. Patients were included if cardiac troponin I was measured and had no evidence of ACS and an echocardiogram was performed. Of 200 patients who met the criteria, baseline characteristics, electrocardiograms, and major adverse cardiovascular events (MACE) were reviewed. Patients were characterized into two groups with normal and elevated troponins. Primary end point was nonfatal myocardial infarction during follow-up period after discharge. The secondary end points were MACE and death from any cause.Results. For 200 patients, 17 patients had positive troponins. Baseline characteristics were as follows: age63.1±13.8, 64% African Americans, 78% with hypertension, and 22% with previous CVA. During mean follow-up of 20.1 months, 7 patients (41.2%) in elevated troponin and 6 (3.3%) patients in normal troponin group had nonfatal myocardial infarction (P=0.0001). MACE (41.2% versus 14.2%,P=0.01) and death from any cause (41.2% versus 14.5%,P=0.017) were significant in the positive troponin group.Conclusions. Elevated cardiac troponin in patients with acute stroke and no evidence of ACS is strong predictor of long-term cardiac outcomes.

Rule Out

BackgroundHigh-sensitivity cardiac troponin assays enable the early risk stratification of patients with suspected acute coronary syndrome to identify those at low risk of myocardial infarction or cardiac death. We evaluated the performance of a novel high-sensitivity cardiac troponin I assay in early rule out pathways.MethodsIn 1920 patients with suspected acute coronary syndrome, cardiac troponin was measured using the Siemens Atellica high-sensitivity cardiac troponin I assay (99th centile: 34 ng/L women, 53 ng/L men). We evaluated three pathways which use either low risk-stratification thresholds of cardiac troponin (High-SensitivityTroponin in the Evaluation of patients with Acute Coronary Syndrome (High-STEACS) and the European Society of Cardiology (ESC) 1 hour pathway) or the 99th centile diagnostic threshold (ESC 3 hour pathway) to rule out myocardial infarction.ResultsThe primary outcome of myocardial infarction or cardiac death at 30 days occurred in 14.4% (277/1920). The High-STEACS pathway ruled out 63% of patients (1218/1920), with five missed events for a negative predictive value (NPV) of 99.5% (95% CI (CI) 99.1% to 99.8%). Similar performance was observed for the ESC 1 hour pathway with an NPV of 99.0% (97.6% to 99.8%). In contrast, the ESC 3 hour pathway ruled out 65% of patients (1248/1920), but missed 25 events for an NPV of 98.0% (97.1% to 98.7%).ConclusionsA novel high-sensitivity cardiac troponin I assay can safely identify patients at low risk of myocardial infarction or cardiac death. Diagnostic pathways that use low cardiac troponin concentrations for risk stratification miss fewer events than those that rely on the 99th centile to rule out myocardial infarction.Trial registrationNCT1852123.
