INTRODUCTION
The diagnosis of non-ST-elevated myocardial infarction (NSTEMI) depends on a combination of history, electrocardiogram, and cardiac biomarkers. The most sensitive and specific biomarkers for cardiac injury are the troponin assays. Many hospitals continue to automatically order less sensitive and less specific biomarkers such as creatine kinase (CK) alongside cardiac troponin (cTn) for workup of patients with chest pain. The objective of this systematic review was to identify whether CK testing is useful in the workup of patients with NSTEMI symptoms.
METHODS
We undertook a systematic review to ascertain whether CK ordered as part of the workup for NSTEMI was useful in screening patients with cardiac chest pain. The MEDLINE, Embase, and Cochrane databases were searched from January 1995-September 2020. Additional papers were added after consultation with experts. We screened a total of 2,865 papers, of which eight were included in the final analysis. These papers all compared CK and cTn for NSTEMI diagnosis.
RESULTS
In each of the eight papers included in the analysis, cTn showed a greater sensitivity and specificity than CK in the diagnosis of NSTEMI. Furthermore, none of the articles published reliable evidence that CK is useful in NSTEMI diagnosis when troponin was negative.
CONCLUSION
There is no evidence to continue to use CK as part of the workup of NSTEMI acute coronary syndrome in undifferentiated chest pain patients. We conclude that CK should not be used to screen patients presenting to the emergency department with chest pain.

Meta-Analysis Review
Several studies have demonstrated the usefulness of cardiac troponin I (cTn) levels in predicting adverse clinical outcomes of patients with anerusmal subarachnoid hemorrhage (aSAH). However, it remains unclear whether cTn levels can be a useful factor in predicting adverse neurologic and cardiovascular outcomes regarding follow-up duration. The study aimed to evaluate the clinical value of cTn elevation among patients with aSAH. A systematic literature search was performed in PubMed and Cochrane to collect original studies that compared the adverse outcomes in patients with aSAH who had elevated cTn levels and those who did not have elevated cTn levels. Data on patient demographics and outcome measurements (mortality, major disability, delayed cerebral ischemia, cardiac dysfunction, and pulmonary edema) were extracted. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were computed by fitting a random effects model. A total of 4,117 patients with aSAH were included in the meta-analysis. Elevated cTn levels was associated with a higher all-cause mortality (OR 3.64; 95% CI 2.68-4.94; I = 22.05%), poor major disability (OR 2.27; 95% CI 1.5-3.37; I = 52.07%), delayed cerebral ischemia (OR 2.10; 95% CI 1.46-3.03; I = 13.80%), cardiac dysfunction (OR 9.20; 95% CI 4.31-19.60; I = 39.89), and pulmonary edema (OR 10.32; 95% CI 5.64-18.90; I = 0.00%). Additionally, elevated cTn levels was associated with higher mortality in prospective studies (OR 3.66; 95% CI 2.61-5.14) as well as when compared with studies with short-term and long-term follow-up periods. Patients with aSAH who had elevated cTn levels also tended to experience poor short-term major disability (OR 2.36; 95% CI 1.48-3.76). Among patients with aSAH, elevated cTn levels was associated with higher mortality and adverse neurologic and cardiovascular outcomes. Given its clinical value, cardiac troponin levels may be included in the assessment of patients withs aSAH.

Journal of Infection and Public Health Sep 2021To systematically investigate the relationship between cardiac biomarkers and COVID-19 severity and mortality. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To systematically investigate the relationship between cardiac biomarkers and COVID-19 severity and mortality.
METHODS
We performed a literature search using PubMed, Web of Science, and Google Scholar. The standardized mean difference (SMD) and 95% confidence interval (CI) were applied to estimate the combined results of 67 studies. A meta-analysis of cardiac biomarkers was used to evaluate disease mortality and severity in COVID-19 patients.
RESULTS
A meta-analysis of 7812 patients revealed that patients with high levels of cardiac troponin I (SMD = 0.81 U/L, 95% CI = 0.14-1.48, P = 0.017), cardiac troponin T (SMD = 0.78 U/L, 95% CI = 0.07-1.49, P = 0.032), high-sensitive cardiac troponin I (SMD = 0.66 pg/mL, 95% CI = 0.51-0.81, P < 0.001), high-sensitive cardiac troponin T (SMD = 0.93 U/L, 95% CI = 0.21-1.65, P = 0.012), creatine kinase-MB (SMD = 0.54 U/L, 95% CI = 0.39-0.69, P < 0.001), and myoglobin (SMD = 0.80 U/L, 95% CI = 0.57-1.03, P < 0.001) were associated with prominent disease severity in COVID-19 infection. Moreover, 9532 patients with a higher serum level of cardiac troponin I (SMD = 0.51 U/L, 95% CI = 0.37-0.64, P < 0.001), high-sensitive cardiac troponin (SMD = 0.51 ng/L, 95% CI = 0.29-0.73, P < 0.001), high-sensitive cardiac troponin I (SMD = 0.51 pg/mL, 95% CI = 0.38-0.63, P < 0.001), high-sensitive cardiac troponin T (SMD = 0.85 U/L, 95% CI = 0.63-1.07, P < 0.001), creatine kinase-MB (SMD = 0.48 U/L, 95% CI = 0.32-0.65, P < 0.001), and myoglobin (SMD = 0.55 U/L, 95% CI = 0.45-0.65, P < 0.001) exhibited a prominent level of mortality from COVID-19 infection.
CONCLUSION
Cardiac biomarkers (cardiac troponin I, cardiac troponin T, high-sensitive cardiac troponin, high-sensitive cardiac troponin I, high-sensitive cardiac troponin T, creatine kinase-MB, and myoglobin) should be more frequently applied in identifying high-risk COVID-19 patients so that timely treatment can be implemented to reduce severity and mortality in COVID-19 patients.

Meta-Analysis
Indirect comparison of TIMI, HEART and GRACE for predicting major cardiovascular events in patients admitted to the emergency department with acute chest pain: a systematic review and meta-analysis.
BACKGROUND
The study aimed to compare the predictive values of the thrombolysis in myocardial infarction (TIMI); History, Electrocardiography, Age, Risk factors and Troponin (HEART) and Global Registry in Acute Coronary Events (GRACE) scoring systems for major adverse cardiovascular events (MACEs) in acute chest pain (ACP) patients admitted to the emergency department (ED).
METHODS
We systematically searched PubMed, Embase and the Cochrane Library from their inception to June 2020; we compared the following parameters: sensitivity, specificity, positive and negative likelihood ratios (PLR and NLR), diagnostic OR (DOR) and area under the receiver operating characteristic curves (AUC).
RESULTS
The pooled sensitivity and specificity for TIMI, HEART and GRACE were 0.95 and 0.36, 0.96 and 0.50, and 0.78 and 0.56, respectively. The pooled PLR and NLR for TIMI, HEART and GRACE were 1.49 and 0.13, 1.94 and 0.08, and 1.77 and 0.40, respectively. The pooled DOR for TIMI, HEART and GRACE was 9.18, 17.92 and 4.00, respectively. The AUC for TIMI, HEART and GRACE was 0.80, 0.80 and 0.70, respectively. Finally, the results of indirect comparison suggested the superiority of values of TIMI and HEART to those of GRACE for predicting MACEs, while there were no significant differences between TIMI and HEART for predicting MACEs.
CONCLUSIONS
TIMI and HEART were superior to GRACE for predicting MACE risk in ACP patients admitted to the ED.

Immunity, Inflammation and Disease Dec 2021To explore the correlation between cardiac-related comorbidities, cardiac biomarkers, acute myocardial injury, and severity level, outcomes in COVID-19 patients. (Meta-Analysis)
Meta-Analysis Review
Cardiac biomarkers, cardiac injury, and comorbidities associated with severe illness and mortality in coronavirus disease 2019 (COVID-19): A systematic review and meta-analysis.
AIMS
To explore the correlation between cardiac-related comorbidities, cardiac biomarkers, acute myocardial injury, and severity level, outcomes in COVID-19 patients.
METHOD
Pubmed, Web of Science, Embase, CNKI, VIP, Wanfang, Cochrane Library databases, medRxiv, and Sinomed were reviewed systemically. Various types of clinical research reporting cardiac-related comorbidities, cardiac biomarkers including lactate dehydrogenase (LDH), troponin I (TnI), high sensitivity troponin I (hs-TnI), creatine kinase (CK), creatine kinase-MB (CK-MB), myoglobin (Myo), N-terminal pro-b-type natriuretic peptide (NT-proBNP) and acute cardiac injury grouped by severity of COVID-19 were included. Outcome measures were events and total sample size for comorbidities, acute cardiac injury, and laboratory parameters of these biomarkers. The study was performed with Stata version 15.1.
RESULTS
Seventy studies, with a total of 15,354 cases were identified. The results showed that COVID-19's severity was related to cardiovascular disease. Similar odds ratios (ORs) were achieved in hypertension except for severe versus critical group (OR = 1.406; 95% CI, 0.942-2.097; p = .095). The relative risk (RR) of acute cardiac injury is 7.01 (95% CI, 5.64-8.71) in non-survivor cases. When compared with the different severity of cardiac biomarkers, the pool OR of CK, CK-MB, TnI, Myo and LDH were 2.683 (95% CI, 0.83-8.671; p = .106; I = 0%), 2.263 (95% CI, 0.939-5.457; p = .069), 1.242 (95% CI, 0.628-2.457; p = .534), 1.756 (95% CI, 0.608-5.071; p = .298; I = 42.3%), 1.387 (95% CI, 0.707-2.721; p = .341; I = 0%) in the critical versus severe group, whose trends were not similar to other groups. The standard mean differences (SMD) of CK and TnI in the critical versus severe group were 0.09 (95% CI, -0.33 to 0.50; p = .685; I = 65.2%), 0.478 (95% CI, -0.183 to 1.138; p = .156; I = 76.7%), which means no difference was observed in the serum level of these indicators.
CONCLUSION
Most of the findings clearly indicate that hypertension, cardiovascular disease, acute cardiac injury, and related laboratory indicators are associated with the severity of COVID-19. What is now needed are cross-national prospectively designed observational or clinical trials that will help improve the certainty of the available evidence and treatment decisions for patients.

Meta-Analysis
BACKGROUND
COVID-19 has been reported in over 40million people globally with variable clinical outcomes. In this systematic review and meta-analysis, we assessed demographic, laboratory and clinical indicators as predictors for severe courses of COVID-19.
METHODS
This systematic review was registered at PROSPERO under CRD42020177154. We systematically searched multiple databases (PubMed, Web of Science Core Collection, MedRvix and bioRvix) for publications from December 2019 to May 31st 2020. Random-effects meta-analyses were used to calculate pooled odds ratios and differences of medians between (1) patients admitted to ICU versus non-ICU patients and (2) patients who died versus those who survived. We adapted an existing Cochrane risk-of-bias assessment tool for outcome studies.
RESULTS
Of 6,702 unique citations, we included 88 articles with 69,762 patients. There was concern for bias across all articles included. Age was strongly associated with mortality with a difference of medians (DoM) of 13.15 years (95% confidence interval (CI) 11.37 to 14.94) between those who died and those who survived. We found a clinically relevant difference between non-survivors and survivors for C-reactive protein (CRP; DoM 69.10 mg/L, CI 50.43 to 87.77), lactate dehydrogenase (LDH; DoM 189.49 U/L, CI 155.00 to 223.98), cardiac troponin I (cTnI; DoM 21.88 pg/mL, CI 9.78 to 33.99) and D-Dimer (DoM 1.29mg/L, CI 0.9 to 1.69). Furthermore, cerebrovascular disease was the co-morbidity most strongly associated with mortality (Odds Ratio 3.45, CI 2.42 to 4.91) and ICU admission (Odds Ratio 5.88, CI 2.35 to 14.73).
DISCUSSION
This comprehensive meta-analysis found age, cerebrovascular disease, CRP, LDH and cTnI to be the most important risk-factors that predict severe COVID-19 outcomes and will inform clinical scores to support early decision-making.

Review
PURPOSE
The aim of this study was to review, systematically, evidence concerning the link between the ACTN3 R577X polymorphism and the rates and severity of non-contact injuries and exercise-induced muscle damage in athletes and individuals enrolled in exercise training programs.
METHODS
A computerized literature search was performed in the electronic databases PubMed, Web of Science, and SPORTDiscus, from inception until November 2020. All included studies compared the epidemiological characteristics of non-contact injury between the different genotypes of the ACTN3 R577X polymorphism.
RESULTS
Our search identified 492 records. After the screening of titles, abstracts, and full texts, 13 studies examining the association between the ACTN3 genotypes and the rate and severity of non-contact injury were included in the analysis. These studies were performed in 6 different countries (Spain, Japan, Brazil, China, the Republic of Korea, and Italy) and involved a total participant pool of 1093 participants. Of the studies, 2 studies involved only women, 5 studies involved only men, and 6 studies involved both men and women. All the studies included were classified as high-quality studies (≥6 points in the Physiotherapy Evidence Database (PEDro) scale score). Overall, evidence suggests there is an association between the ACTN3 R577X genotype and non-contact injury in 12 investigations. Six studies observed a significant association between ACTN3 R577X polymorphism and exercise induced muscle damage: 2 with non-contact ankle injury, 3 with non-contact muscle injury, and 1 with overall non-contact injury.
CONCLUSION
The present findings support the premise that possessing the ACTN3 XX genotype may predispose athletes to a higher probability of some non-contact injuries, such as muscle injury, ankle sprains, and higher levels of exercise-induced muscle damage.

OBJECTIVE
Recent advances in cardiac MRI (CMR) and other diagnostic techniques have made it easier to identify subclinical cardiac inflammation and dysfunction in the idiopathic inflammatory myopathies (IIM). Herein, we systematically review the literature regarding cardiac involvement in IIM.
METHODS
We searched Medline and EMBASE from 1990 to 2020 using keywords related to IIM and cardiac disease. We included English language studies in adults with any immune-mediated, inflammatory muscle pathology.
RESULTS
We identified 10 425 potentially relevant abstracts, of which 29 were included. Most frequently these included patients with PM or DM without symptomatic myocarditis. Five categories of cardiac investigation were used in these patients: cardiac enzyme testing, ECG, transthoracic echocardiography, CMR and nuclear medicine testing. Patients with clinical myocarditis had universally abnormal cardiac troponin levels and ECG. Elevated cardiac troponin T was more common than cardiac troponin I and may correlate with disease activity, whereas cardiac troponin I was more specific for cardiac involvement. Non-specific ECG changes were common. The major finding on transthoracic echocardiography was abnormal ejection fraction. Gross systolic dysfunction was unusual, but subclinical systolic dysfunction was reported in several studies. Abnormal diastolic function was common and may be associated with disease duration. Late gadolinium enhancement (reflecting regional necrosis or scarring) and abnormal myocardial mapping parameters (reflecting myocardial inflammation, fibrosis and oedema) were frequently identified on CMR, suggesting significant subclinical myocardial pathology (despite typically normal ejection fraction).
CONCLUSION
Abnormal cardiac investigations are commonly found in asymptomatic IIM patients, which has potential prognostic and treatment implications.

Meta-Analysis
OBJECTIVE
A meta-analysis of laboratory cardiac markers for multisystem inflammatory syndrome in children (MIS-C) was performed in patients with coronavirus disease 2019 (COVID-19).
METHODS
Eight databases were searched until April 10, 2021, for studies on cardiac markers, including B-type natriuretic peptide (BNP)/N-terminal pro-BNP (NT-proBNP), troponin, aspartate aminotransferase (AST), in MIS-C patients.
RESULTS
Of the 2583 participants enrolled in 24 studies, 1613 patients were diagnosed with MIS-C. MIS-C patients exhibited higher BNP levels than patients with non-severe COVID-19 [SMD (95% CI): 1.13 (0.48, 1.77), p < 0.05]. No significant differences in BNP levels were observed between patients with MIS-C and severe COVID-19 [SMD (95% CI): 0.29 (-0.07, 0.65), p = 0.117]. Comparisons of MIS-C patients to all COVID-19 patients revealed no significant differences in levels of troponin [SMD (95% CI): 0.13 (-0.07, 0.32), p = 0.212] or AST [SMD (95% CI): 0.10 (-0.11, 0.31), p = 0.336]. Compared to patients with non-severe MIS-C, those with severe MIS-C exhibited higher levels of BNP [SMD (95% CI): 0.26 (0.04, 0.48), p < 0.05], but no differences in troponin [SMD (95% CI): 0.05 (-0.06, 0.16) p = 0.387] or AST [SMD (95% CI): 0.19 (-0.34, 0.71), p = 0.483] were observed. Moreover, there was no significant difference in BNP [SMD (95% CI): -0.21 (-1.07, 0.64), p = 0.624] or troponin [SMD (95% CI): -0.07 (-0.45, 0.31), p = 0.710] between MIS-C with and without coronary artery abnormality. Sensitivity analyses were performed to assess stability. No publication bias was detected based on Begg's test.
CONCLUSIONS
The key cardiac marker that showed differences between patients with MIS-C/non-severe COVID-19 and between patients with severe/non-severe MIS-C was BNP. Other markers, such as troponin and AST, did not exhibit notable differences in indicating cardiac injury between patients with MIS-C and COVID-19.

Meta-Analysis
The optimal timing of aortic valve replacement (AVR) remains controversial. Several biomarkers reflect the underlying pathophysiological processes in aortic stenosis (AS) and may be of use as mortality predictors. The aim of this systematic review and meta-analysis is to evaluate the blood biomarkers utilised in AS and assess whether they associate with mortality. PubMed and Embase were searched for studies reporting baseline biomarker level and mortality outcomes in patients with AS. A total of 83 studies met the inclusion criteria and were systematically reviewed. Of these, 21 reporting brain natriuretic peptide (BNP), N-terminal pro B-type natriuretic peptide (NT-proBNP), Troponin and Galectin-3 were meta-analysed. Pooled analysis demonstrated that all-cause mortality was significantly associated with elevated baseline levels of BNP (HR 2.59; 95% CI 1.95-3.44; < 0.00001), NT-proBNP (HR 1.73; 95% CI 1.45-2.06; = 0.00001), Troponin (HR 1.65; 95% CI 1.31-2.07; < 0.0001) and Galectin-3 (HR 1.82; 95% CI 1.27-2.61; < 0.001) compared to lower baseline biomarker levels. Elevated levels of baseline BNP, NT-proBNP, Troponin and Galectin-3 were associated with increased all-cause mortality in a population of patients with AS. Therefore, a change in biomarker level could be considered to refine optimal timing of intervention. The results of this meta-analysis highlight the importance of biomarkers in risk stratification of AS, regardless of symptom status.
