Abstract
AIMS Epidemiological evidence is extremely limited about high-sensitivity cardiac troponin T (hs-cTnT) and future coronary heart disease (CHD) events for the general population in countries with low mortality from CHD. Therefore, we investigated the association between hs-cTnT levels and the risk of incident CHD using a nested case-control study in a large Japanese cohort study. METHODS The participants were residents of four Japanese communities in the Circulatory Risk in Communities Study (CIRCS). We obtained 120 cases (81 men and 39 women, aged 38-86 years at baseline) of first incident CHD and 240 controls matched by age, sex, communities, and blood sampling term. Serum hs-cTnT levels were measured using an electrochemiluminescence immunoassay with stored sera collected between 2001 and 2011. The median period between sampling at survey and CHD incidence was 2.0 (interquartile range, 0.9-3.7) years. After adjusting for conventional risk factors, the multivariable odds ratios (ORs) of CHD were calculated using conditional logistic regression analyses. RESULTS hs-cTnT ranged from ≤ 3 (assay detection limit) to 155 ng/L. Compared with the lowest quartile of hs-cTnT, multivariable ORs (95% confidence intervals) of CHD for the second, third, and highest quartiles were 1.30 (0.57-2.95), 2.48 (1.09-5.64), and 3.01 (1.27-7.12), respectively. Similar associations were observed after adjusting for estimated glomerular filtration, or after excluding matched groups, including people with chronic kidney disease. CONCLUSION Serum hs-cTnT could predict CHD in the Japanese general population. These findings implicate a benefit from monitoring hs-cTnT to predict CHD even among populations in countries with low mortality from CHD.

Elevation of Highly Sensitive Cardiac Troponin T Among End-Stage Renal Disease Patients Without Acute Coronary Syndrome. Malays J Med Sci 2022; 28:64-71. [PMID: 35115888 PMCID: PMC8793973 DOI: 10.21315/mjms2021.28.5.6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 06/26/2021] [Indexed: 02/08/2023] Open
Abstract
Background In end-stage renal disease (ESRD), troponin T concentrations can be elevated even without cardiac ischaemia, which hampers the diagnosis of acute myocardial infarction (AMI). The objectives of our study were to determine the proportion of dialysisdependent ESRD patients without acute coronary syndrome (ACS) but with highly sensitive cardiac troponin T (hs-cTnT) levels above the 99th percentile upper reference limit and to evaluate the range of hs-cTnT among this population. Methods A cross-sectional study was conducted at the haemodialysis (HD) unit of a tertiary hospital in Malaysia from January 2018 to February 2019. Dialysis-dependent ESRD patients were included and those with a recent history of ACS (within 30 days) were excluded. Pre-dialysed serum hs-cTnT levels were measured using Cobas e411. The upper limit of the 99th percentile value for troponin T was 14 ng/L. Results A total of 150 patients were recruited as study participants. The majority were female (62%) and of Malay ethnicity (94%), and the mean (SD) age was 45.19 (16.36) years old. The hs-cTnT range (min, max) was 11.39–738.30 ng/L and the median (interquartile range [IQR]) of hs-cTnT was 59.20 (83.41) ng/L. Elevated hs-cTnT levels were observed in 149/150 (99%) of the study participants (54/55 [98.2%] of the patients were on HD, and 95/95 [100.0%] of the patients were on continuous ambulatory peritoneal dialysis). Conclusion This study supports prior research showing that even without ACS, most ESRD patients have elevated concentrations of cardiac troponin. Furthermore, our study illustrates the need to revisit the use of absolute troponin values when making a diagnosis of ACS in ESRD patients.

Abstract
OBJECTIVES The relationship between high-sensitive cardiac troponin T concentration (hs-cTnT) and renal markers levels is known. However, the extent to which their variations are associated remains to be explored. Objective: model the relationship between relative changes in hs-cTnT (Δhs-cTnT) and variations in creatinine (Δcre) or estimated glomerular filtration rate (ΔeGFR), using a quantile generalized additive model (qgam). METHODS Concomitant plasma Δhs-cTnT and Δcre from patients aged 18-100 years, selected with a time variation (Δtime) of 3 h-7 days, were collected over a 5.8-year period. Relationships between Δhs-cTnT and covariates Δcre (A) or ΔeGFR (B), including age, Δtime, hour of blood sampling (HSB) and covariates interactions were fitted using qgam. RESULTS On the whole (n=106567), Δhs-cTnT was mainly associated with Δcre, in a positive and nonlinear way (-21, -6, +5, +20, +55% for -50, -20, +20, +50, +100%, respectively), but to a lesser extent with age (min -9%, max +2%), Δtime (min -4%, max +8%), and HSB (min -5%, max +7%). Δhs-cTnT was negatively associated with ΔeGFR (+46, +7, -5, -11, -20% for -50, -20, +20, +50, +100%, respectively). Classifying Δhs-cTnT as consistent or not with myocardial injury based on recommendations, an interpretation of Δhs-cTnT adjusted for model A or B led to statistically significant but small diagnostic discrepancies (<2%), as compared to an interpretation based on Δhs-cTnT only. CONCLUSIONS From a laboratory and statistical standpoint, considering renal function variations when interpreting relative changes in cardiac troponin T has a minor impact on the diagnosis rate of myocardial injury.

Abstract
BACKGROUND Blunt cardiac injuries (BCI) result in poor outcomes following chest trauma. Admission ECG and troponin levels are frequently obtained in patients with suspected BCI, nevertheless, the prognostic value of cardiac troponins remains controversial. The purpose of the current study was to review the prognostic value of elevated high-sensitivity cardiac troponin T (hs-cTnT) in patients with severe blunt chest injuries. We hypothesized that elevated hs-cTnT result in poor outcomes in this subgroup of severe trauma patients. METHODS After IRB approval, all consecutive patients with Injury Severity Score (ISS) > 15 and chest Abbreviated Injury Scale (AIS) score ≥3 admitted to the major trauma centers between 1/2015 and 6/2017 were retrospectively reviewed. Primary outcomes were in-hospital and one-year mortality. Secondary outcomes included ventilator days and Glasgow Outcome Scale (GOS) score at hospital discharge. RESULTS Overall, 147 patients were included. Mean age was 49.0 (19.1) years and 75% were male. Serum troponin levels on admission were accrued in 82 (56%) patients with elevated and normal hs-cTnT levels found in 54 (66%) and in 28 (34%) patients, respectively. Elevated hs-cTnT group had significantly higher ISS and lactate level, and lower systolic blood pressure on admission. In-hospital mortality was significantly higher in patients with elevated hs-cTnT levels compared to patients with normal hs-cTnT levels (26% vs. 4%, p = 0.02). Hs-cTnT level > 14 ng/L was significantly associated with extended ventilator days and lower GOS score at hospital discharge. CONCLUSION Blunt chest trauma victims with elevated hs-cTnT levels experience significantly poorer adjusted outcomes compared to patients with normal levels. Compliance with EAST practice management guidelines following severe blunt chest trauma was not fully complied in our study cohort that warrants prospective performance improvement measures.

Abstract
BACKGROUND The definition of myocardial infarction relies on elevated troponin levels. However, elevated levels of high sensitive cardiac troponin (hs-cTnT) assays have been reported in elderly patients without acute myocardial infarction. We sought to determine whether elevated hs-cTnT levels have a prognostic value in stable elderly subjects without any acute illness. METHODS The study cohort included residents of a nursing home who were asymptomatic without any acute medical problem. Serum hs-cTnT levels were measured, and participants were divided into high and low hs-cTnT groups. We measured hs-cTnT levels of young healthy volunteers as well and compared them with hs-cTnT levels of those nursing home residents. RESULTS Fifty-seven nursing home residents and 14 young volunteers were included in the study. The average age of nursing home residents was 83 ± 14 years, compared with 37 ± 3 years of the volunteers. Levels of hs-cTnT were significantly higher in the elderly compared with the volunteers (0.02 ± 0.016 ng/mL vs 0.005 ± 0.0003 ng/mL; P < .001); accordingly, we chose a cutoff of 0.02 ng/mL hs-cTnT and divided the 57 patients into 2 subgroups for further evaluation. After adjustment for age, gender, and glomerular filtration rate, the hs-cTnT was still an independent predictor of 1-year mortality (relative risk 2.04 [95% conficence interval, 2.009-29.45], P = .003). CONCLUSIONS Mild elevations of hs-cTnT levels are common in elderly patients, and hs-cTnT level is an independent marker of mortality risk in this population. For patients older than 70 years, a different hs-cTnT cutoff is required (eg, higher than 0.014 ng/mL).

Abstract
Background The principal goal of this study was to determine the importance of high-sensitivity troponin T (hs-TnT) and creatine kinase MB isoenzyme (CK-MB) in predicting cardiovascular events in asymptomatic end-stage renal disease (ESRD) patients. Methods This study included 110 participants; 54 ESRD patients undergoing hemodialysis and 56 healthy control participants. Biochemical parameters and cardiac markers were estimated. Comparative utilities were assessed through logistic regression and receiver operating characteristic (ROC) analyses. Results We found that 96.3% of ESRD patients had an elevated level of hs-TnT (mean, 0.049 ± 0.0324 μg/L) compared to healthy participants. Among patients with ESRD, hs-TnT showed significant correlations with the low-density lipoprotein cholesterol/high-density lipoprotein cholesterol (HDL-C) (P = 0.042, r = 0.278) and total cholesterol/HDL-C (P = 0.044, r = 0.276) ratios. CK-MB (odds ratio [OR], 1.138; P = 0.04) and hs-TnT (OR, 2.153; P = 0.017) predicted cardiovascular events on logistic regression analysis, and the prediction was improved by the model that combined two cardiac markers. The diagnostic performance of hs-TnT and CK-MB alone and the combination of the two biomarkers was assessed by the area under the ROC curve (AUC). The highest AUC was produced by the combination of hs-TnT and CK-MB markers (0.920) compared to hs-TnT or CK-MB alone. Conclusion In asymptomatic patients with ESRD, hs-TnT appeared to be an important predictor for cardiovascular mortality, and its diagnostic accuracy improved with CK-MB. This study provides new insights into the predictive value of multiple biomarkers for identifying cardiovascular events in ESRD patients on hemodialysis.

Abstract
Real-time three-dimensional echocardiography(RT-3DE) has allowed a better assessment of LA volumes and function. We sought to assess the early change in left atrial size and function in patients treated with anthracyclines using RT-3DE. 61 patients aged 44.9 ± 11.9 years with large B-cell non-Hodgkin lymphoma treated with doxorubicin were studied. Blood collection and echocardiography were performed at baseline and 1 day after completion of the chemotherapy. Global longitudinal strain (GLS), maximum, minimum and pre-atrial contraction LA volumes were measured and reservoir, conduit and booster pump function were assessed. Despite normal LVEF, passive emptying percent of total emptying (0.51 ± 0.14 vs. 0.40 ± 0.12, P < 0.001) and passive emptying index (0.29 ± 0.10 vs. 0.23 ± 0.06, P < 0.001) were remarkably reduced compared to baseline values, while active emptying percent of total emptying (0.49 ± 0.14 vs. 0.60 ± 0.12, P < 0.001) and active emptying index (0.41 ± 0.16 vs. 0.47 ± 0.16, P = 0.048) were increased. GLS (−21.64 ± 2.83 vs. −17.30 ± 2.50) was markedly reduced, cTnT levels was elevated from 0.005 ± 0.004 to 0.020 ± 0.026 ng/mL at the completion of chemotherapy (P all < 0.001). Early LA functional change occur after doxorubicin exposure in patients with preserved LVEF, which could be detected by RT-3DE.

Abstract
Background Urine albumin excretion is an important predictor of adverse cardiovascular events. Minimally elevated levels of serum cardiac troponin T (cTnT), a marker of cardiomyocyte micronecrosis, can be detected with high sensitivity cTnT (hs-cTnT) assays. The purpose of this study was to investigate the relationship between alterations in albuminuria and serum hs-cTnT levels in a community-based population. Methods We examined the association between the urine albumin/creatinine ratio (UACR) and hs-cTnT levels in 1354 participants without overt cardiovascular disease in a community-based, cross-sectional study in Beijing, China. Results With the highly sensitive assay, cTnT levels were detectable in 90.5% of our subjects. The median (interquartile range) concentrations of hs-cTnT were 7 (5–10) pg/mL. After adjustment for several factors, UACR (odds ratio: 1.40; 95% confidence interval: 1.08–1.65; P = 0.002) was associated with a higher likelihood of elevated hs-cTnT (≥14 pg/ mL), whereas the relationship between UACR and a higher presence of detectable hs-cTnT (≥ 3 pg/ mL) was not significant. In addition, a fully adjusted logistic regression analysis revealed that compared with participants in the lowest UACR quartile, those in the highest quartile had a 2.43- fold (95% CI: 1.25–5.08; P = 0.006) increased risk of elevated hs-cTnT. Conclusions Higher urine albumin excretion is associated with elevated hs-cTnT among persons without clinically evident cardiovascular disease, suggesting that albuminuria may be a potential risk factor for subclinical cardiovascular disease in the general population.

Abstract
To systematically investigate putative causes of non-coronary high-sensitive troponin elevations in patients presenting to a tertiary care emergency department. In this cross-sectional analysis, patients who received serial measurements of high-sensitive troponin T between 1 August 2010 and 31 October 2012 at the Department of Emergency Medicine were included. The following putative causes were considered to be associated with non-acute coronary syndrome-related increases in high-sensitive troponin T: acute pulmonary embolism, renal insufficiency, aortic dissection, heart failure, peri-/myocarditis, strenuous exercise, rhabdomyolysis, cardiotoxic chemotherapy, high-frequency ablation therapy, defibrillator shocks, cardiac infiltrative disorders (e.g., amyloidosis), chest trauma, sepsis, shock, exacerbation of chronic obstructive pulmonary disease, and diabetic ketoacidosis. During the study period a total of 1,573 patients received serial measurements of high-sensitive troponin T. Of these, 175 patients were found to have acute coronary syndrome leaving 1,398 patients for inclusion in the study. In 222 (30 %) of patients, no putative cause described in the literature could be attributed to the elevation in high-sensitive troponin T observed. The most commonly encountered mechanism underlying the troponin T elevation was renal insufficiency that was present in 286 patients (57 %), followed by cerebral ischemia in 95 patients (19 %), trauma in 75 patients (15 %) and heart failure in 41 patients (8 %). Non-acute coronary syndrome-associated elevation of high-sensitive troponin T levels is commonly observed in the emergency department. Renal insufficiency and acute cerebral events are the most common conditions associated with high-sensitive troponin T elevation.

High-sensitivity cardiac troponin T (hs-cTnT) is a biomarker used in diagnosing myocardial injury. The clinical utility and the variation of this biomarker over time remain unclear in hemodialysis (HD) and peritoneal dialysis (PD) patients. We sought to determine whether hs-cTnT concentrations were predictive of myocardial infarction (MI) and death and to examine hs-cTnT variability over a 1-year period.
METHODS
A total of 393 nonacute HD and PD patients (70% HD and 30% PD) were followed in a prospective observational study for new MI and death.
RESULTS
Median hs-cTnT was 57 ng/L (interquartile range, 36–101 ng/L) with no observed difference between HD and PD patients (P = 0.11). Incremental increases in mortality (P = 0.024) and MI (P = 0.001) were observed with increasing hs-cTnT quartiles. MI incidence increased significantly across quartiles in both HD and PD patients (P = 0.012 and P = 0.025, respectively), whereas mortality increased only in HD patients (P = 0.015). For every increase of 25 ng/L in hs-cTnT, the unadjusted hazard ratio (HR) was 1.10 for mortality in the whole group (95% CI, 1.04–1.16, P = 0.001) and 1.16 for MI (95% CI, 1.08–1.23, P < 0.001). Adjusted HR for mortality was 1.07 (95% CI, 1.01–1.15, P = 0.04) and 1.14 for MI (95% CI, 1.06–1.22, P < 0.001). Changes in hs-cTnT from baseline concentrations after 1 year were minimal (55 ng/L vs 53 ng/L, P = 0.22) even in patients who had an MI (P = 0.53).
CONCLUSIONS
hs-cTnT appears to have a useful role in predicting MI and death in the dialysis population. Over a 1-year period concentrations remained stable even in patients who sustained a new cardiac event.

Abstract
Background Chronic kidney disease (CKD) is generally considered an independent risk factor for cardiovascular disease (CVD) development, but rates in individuals with estimated glomerular filtration rate (eGFR) >60 ml/min/1.73 m2 are uncertain. The Framingham global CVD risk score (FRS) equation is a widely accepted tool used to predict CVD risk in the general population. The purpose of the present study was to examine whether an association exists between eGFR and FRS in a Chinese population with no CKD or CVD. Methods A total of 333 participants were divided into three groups based on FRS. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and CKD-EPI equation for Asians (CKD-EPI-ASIA) were used to measure eGFR. Results A significant inverse association between eGFR and FRS was confirmed with Pearson correlation coefficients of –0.669, –0.698 (eGFRCKD-EPI, P<0.01) and –0.658, –0.690 (eGFRCKD-EPI-ASIA, P<0.01). This association gradually diminished with progression from the low- to high-risk groups (eGFRCKD-EPI, r = –0.615, –0.282, –0.197, P<0.01, P<0.01, P>0.05; similar results according to the CKD-EPI-ASIA equation). In the low- or moderate-risk new-groups, this association became stronger with increased FRS (eGFRCKD-EPI-ASIA, r = –0557, –0.622 or –0.326, –0.329, P<0.01). In contrast to the results from 2008, eGFR was independently associated with FRS following adjustment for traditional cardiovascular risk factors (P<0.05). Conclusion Renal function has multiple influences on predicting CVD risk in various populations. With increasing FRS and decreasing eGFR, it is also independently associated with CVD, even in individuals with eGFR >60 ml/min/1.73 m2.

Am J Cardiol 2013; 112:1968-72. [PMID: 24091183 DOI: 10.1016/j.amjcard.2013.08.028] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2013] [Revised: 08/06/2013] [Accepted: 08/06/2013] [Indexed: 12/27/2022]
Abstract
In the present study, we wanted to (1) evaluate whether high-sensitive troponin T levels correlate with the grade of renal insufficiency and (2) test the accuracy of high-sensitive troponin T determination in patients with renal insufficiency for diagnosis of acute myocardial infarction (AMI). In this cross-sectional analysis, all patients who received serial measurements of high-sensitive troponin T from August 1, 2010, to October 31, 2012, at the Department of Emergency Medicine were included. We analyzed data on baseline characteristics, reason for referral, medication, cardiovascular risk factors, and outcome in terms of presence of AMI along with laboratory data (high-sensitive troponin T, creatinine). A total of 1,514 patients (67% male, aged 65 ± 16 years) were included, of which 382 patients (25%) had moderate to severe renal insufficiency and significantly higher levels of high-sensitive troponin T on admission (0.028 vs 0.009, p <0.0001). In patients without AMI, high-sensitive troponin T correlated inversely with the estimated glomerular filtration rate (R = -0.12, p <0.0001). Overall, sensitivity of an elevated high-sensitive troponin for diagnosis of AMI was 0.64 (0.56 to 0.71) and the specificity was 0.48 (0.45 to 0.51). The area under the curve of the receiver operating characteristic for all patients was 0.613 (standard error [SE] 0.023), whereas it was 0.741 (SE 0.029) for patients with a Modification of Diet in Renal Disease estimated glomerular filtration rate >60 ml/min presenting with acute chest pain or dyspnea and 0.535 (SE 0.056) for patients with moderate to severe renal insufficiency presenting with acute chest pain or dyspnea. In conclusion, the diagnostic accuracy for presence of AMI of a baseline measurement of high-sensitive troponin in patients with renal insufficiency was poor and resembles tossing a coin.
