The predictive value of high-sensitive troponin I for perioperative risk in patients undergoing gastrointestinal tumor surgery

Aim: To explore, which differential diagnoses to consider in individuals with elevated troponins without acute myocardial infarction (AMI), and the mortality for those individuals. Methods: Retrospective, register-based study on a representative sample of the Danish population with the following inclusion criteria: High-sensitive troponin I (hs-TnI) ≥25 ng/L, age ≥18 years, and exclusion of AMI. Results: 3067 individuals without AMI but increased hs-TnI were included. Most frequent discharge diagnoses: Pneumonia (12.8%), Aortic valve disorder (11.3%), Medical observation (10.9%) and Heart failure (8.9%). The 30-days and one-year mortality was 15.8% and 32.0%, respectively. Conclusions: A selected number of alternative diagnoses must be considered in individuals with increased hs-TnI. Due to high mortality it is crucial to carefully evaluate these individuals despite the absence of AMI.

Abstract Objective Myocarditis is an inflammatory disease of the heart caused by various agents and especially enteroviruses, and it is difficult to diagnose and treat. Myocarditis is rarely associated with bacterial infections. Although the most common bacterial infections are Salmonella spp. and Shigella spp., extremely rare cases of Myocarditis due to Campylobacter jejuni are also reported. Patient and methods A 17-year-old male patient with no previous chronic illness was admitted to our emergency department with complaints of abdominal pain, diarrhea, vomiting, and chest pain. He stated that symptoms began after eating a chicken burger a few days ago. Results In the laboratory tests performed, CK-MB and high sensitive Troponin I values were determined as 33.8 IU/L and 1816 ng/L, respectively. Electrocardiogram results revealed left axis left anterior hemiblock in the normal sinus rhythm as well as a ST-T change in the inferior and lateral derivations. Campylobacter jejuni was detected in the stool sample of the patient. Conclusion Myocarditis is one of the rare complications of C. jejuni infection. Bacterial myocarditis should be considered when troponin and cardiac enzymes are elevated in patients admitted to the emergency department with diarrhea and chest pain.

Abstract Background There is overwhelming volume of confirmed cases of COVID-19, despite this numerous knowledge gaps remain in the diagnosis, management, and prognostication of this novel coronavirus infection, making prevention and control a challenge. Methods This retrospective cohort study included patients with real-time reverse transcriptase polymerase chain reaction (rRT-PCR)-confirmed COVID-19. Binary logistic regression was used to determine the association between the cardiac biomarkers and in-hospital mortality. ROC, AUC, and cutoff analyses were used to determine optimal cutoff values for the cardiac biomarkers. Results A total of 90 subjects with a complete panel of cardiac biomarkers out of the 224 rRT-PCR confirmed cases were included. The median age was 57 years (IQR, 47–67 years), majority were males. Sixty-six (77.6%) subjects survived while 19 (22.4%) expired. The most common presenting symptom was fever (75.6%), and the most common comorbidity was hypertension (67.8%). Spearman rho correlation analysis showed moderate positive association of high sensitivity troponin I (hsTnI) with in-hospital mortality (R, 0.434, p = <0.001). Multivariate binary logistic regression analysis showed that creatine kinase and hsTnI were independently associated with in-hospital mortality (OR, 4.103 [95% CI, 1.241–13.563], p=0.021; and OR, 7.899 [95% CI, 2.430–25.675], p=0.001, respectively). ROC curve analysis showed that hsTnI was a good predictor for in-hospital mortality (AUC, 0.829 [95% CI, 0.735–0.923], p = <0.001) and that creatine kinase was a poor predictor (AUC, 0.677 [95% CI, 0.531–0.823], p=0.018). Optimal cutoff point derived from the ROC curve for hsTnI was 0.010 ng/ml (J, 0.574) with a sensitivity of 84% (TPR, 0.842 [95% CI, 0.604–0.966]), specificity of 73% (TNR, 0.732 [95% CI, 0.614–0.386]), and an adjusted negative predictive value of 99% (Known prevalence*adjusted NPV, 0.989), a positive likelihood ratio of 20% (LR+, 3.147 [95% CI, 2.044–4.844]) and a negative likelihood ratio of 30% (LR−, 0.216 [95% CI, 0.076–0.615]). Conclusion High sensitivity troponin I level was a good tool with a very high negative predictive value in significantly predicting in-hospital mortality among rRT-PCR positive COVID-19 patients.

Rule Out

Abstract Introduction According to ESC guidelines, an acute myocardial infarction (MI) can be excluded without serial troponin measurements in patients presenting with a single high-sensitive troponin below the 99th percentile and chest pain starting >6 hours prior to admission. However, it is unclear if single-testing of high-sensitive troponin can rule-out MI in early presenters. Purpose To investigate the diagnostic performance of a single value of high-sensitive cardiac troponin I (hs-cTnI) at presentation for ruling-out MI in patients presenting with chest pain to the Emergency Department irrespective of chest pain onset. Methods We conducted a substudy of preliminary data from the RACING-MI trial. We included patients presenting with chest pain suggestive of MI to the Emergency Department of a Regional Hospital. We used the Siemens hs-cTnI (Siemens Healthcare, TNIH, Limit of detection: 2.21 ng/L) and a diagnostic cut-off value <3 ng/L to rule-out MI at presentation. Two physicians independently adjudicated the final diagnosis based on all clinical information. Patients were stratified based on time from chest pain onset to hospital admission as very early (0–3 hours), early (3–6 hours) and late presenters (>6 hours). Results We included 989 patients with available hs-cTnI results at admission. MI was confirmed in 82 (8.3%) patients. Using hs-cTnI <3 ng/L as diagnostic cut-off value at presentation, 302 (30.5%) patients without MI were classified as rule-out. Overall, the negative predictive value (NPV) for MI was 100% (95% CI 98.7–100). Based on chest pain onset, 33.8% of patients were classified as very early, 12.8% as early, and 42.7% as late presenters, with 10.7% patients with unreported/unknown onset. NPV was 100% (95% CI 96.5–100) for very early, 100% (95% CI 88.3–100) for early and 100% (95% CI 97.3–100) for late presenters. Conclusions Using a single hs-cTnI value <3ng/L as diagnostic cut-off to rule-out MI seems to be safe and to allow rapid rule-out of MI in patients presenting with chest pain to the emergency department, even in very early presenters.

Rule Out

Background: Copeptin in combination with troponin has been shown to have incremental value for the early rule-out of myocardial infarction, but its performance in Black patients specifically has never been examined. In light of a potential for wider use, data on copeptin in different relevant cohorts are needed. This is the first study to determine whether copeptin is equally effective at ruling out myocardial infarction in Black and Caucasian races. Methods: This analysis of the CHOPIN trial included 792 Black and 1075 Caucasian patients who presented to the emergency department with chest pain and had troponin-I and copeptin levels drawn. Results: One hundred and forty-nine patients were diagnosed with myocardial infarction (54 Black and 95 Caucasian). The negative predictive value of copeptin at a cut-off of 14 pmol/l (as in the CHOPIN study) for myocardial infarction was higher in Blacks (98.0%, 95% confidence interval (CI) 96.2–99.1%) than Caucasians (94.1%, 95% CI 92.1–95.7%). The sensitivity at 14 pmol/l was higher in Blacks (83.3%, 95% CI 70.7–92.1%) than Caucasians (53.7%, 95% CI 43.2–64.0%). After controlling for age, hypertension, heart failure, chronic kidney disease and body mass index in a logistic regression model, the interaction term had a P value of 0.03. A cut-off of 6 pmol/l showed similar sensitivity in Caucasians as 14 pmol/l in Blacks. Conclusions: This is the first study to identify a difference in the performance of copeptin to rule out myocardial infarction between Blacks and Caucasians, with increased negative predictive value and sensitivity in the Black population at a cut-off of 14 pmol/l. This also holds true for non-ST-segment elevation myocardial infarction and, although numbers were small, similar trends exist in the normal troponin population. This may have significant implications for early rule-out strategies using copeptin.

High Sensitive Troponin

Abstract Background and objectives Patients with human immunodeficiency virus (HIV) infection live longer and the prevalence of coronary heart disease is increasing among them. High-sensitive troponin I (hs-TnI) is associated with coronary artery calcification as determined by non-contrast cardiac computed tomography (CT) in general population without established cardiovascular disease (CVD). Nevertheless, the relationship in well-controlled HIV-infected patients has not been validated. Design and methods A cross-sectional study among HIV-infected adults aged >50 years free from known CVDs. All subjects underwent non-contrast cardiac CT and blood test for serum hs-TnI was concomitantly performed. Relationship between Agatston score, a parameter used to quantify coronary artery calcification and serum hs-TnI level was analysed using spearman correlation and logistic regression models. Results A total of 338 HIV-infected adults (median age 54 years, 62% men) were included. All of them were in antiretroviral therapy with a median 18 years of exposure. The median CD4 cell count was 614 cell/mm3, 98% were virologically suppressed. Hs-TnI was correlated with coronary artery calcification with the correlation coefficient of 0.287 (p<0.0001). Multivariated logistic regression analysis demonstrated that serum hs-TnI concentration was associated with an increased odd of coronary artery calcification (Agatston score>0) (OR 1.64; 95% CI, 1.05–2.56, p=0.029). To detect coronary artery calcification, using the hs-TnI in addition to Thai CV risk score slightly increased the ROCAUC from 0.6827 to 0.692 (p=0.45). Distribution of CAC score over hs-TnI Conclusion Among well-controlled HIV-infected patients without established CVDs, hs-TnI concentration was associated with coronary artery calcification. This could be a potential biomarker for an early risk stratification of subclinical coronary atherosclerosis in this population. The association with long-term adverse cardiovascular outcome needs to be validated in the future study.
