Abstract
Cardiovascular diseases (CVDs), especially chronic heart failure, threaten many patients' lives worldwide. Because of its slow course and complex causes, its clinical screening, diagnosis, and prognosis are essential challenges. Clinical biomarkers and biosensor technologies can rapidly screen and diagnose. Multiple types of biomarkers are employed for screening purposes, precise diagnosis, and treatment follow-up. This article provides an up-to-date overview of the biomarkers associated with the six main heart failure etiology pathways. Plasma natriuretic peptides (BNP and NT-proBNP) and cardiac troponins (cTnT, cTnl) are still analyzed as gold-standard markers for heart failure. Other complementary biomarkers include growth differentiation factor 15 (GDF-15), circulating Galactose Lectin 3 (Gal-3), soluble interleukin (sST2), C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-α). For these biomarkers, the electrochemical biosensors have exhibited sufficient sensitivity, detection limit, and specificity. This review systematically summarizes the latest molecular biomarkers and sensors for heart failure, which will provide comprehensive and cutting-edge authoritative scientific information for biomedical and electronic-sensing researchers in the field of heart failure, as well as patients. In addition, our proposed future outlook may provide new research ideas for researchers.

Abstract
PURPOSE OF REVIEW In systemic sclerosis (SSc) primary heart involvement (pHI) is frequent, even though often unrecognized due to its occult nature and to the lack of a specific diagnostic algorithm. The purpose of this review is to report the state of the art of the evidence in the current literature, as well as the overall diagnostic modalities and therapeutic strategies for primary heart involvement in SSc. RECENT FINDINGS SSc-pHI is defined by the presence of cardiac abnormalities that are predominantly attributable to SSc rather than other causes and/or complications; it may be sub-clinical and must be confirmed through diagnostic investigations. Novel electrocardiographic analysis and cardiac magnetic resonance (CMR) with mapping techniques have been recently proposed, showing a great utility in the early identification of SSc-pHI and in the noninvasive characterization of myocardial tissue. Immunosuppressive therapy emerged as fundamental to curb myocardial inflammation, and recent preclinical and clinical data support the role of antifibrotic drugs to treat SSc-pHI. SUMMARY our review will help clinicians to properly integrate the available diagnostic modalities for the assessment of SSc-pHI. The ultimate goal is to propose a feasible diagnostic algorithm for the early identification of patients with SSc-pHI, and a schematic therapeutic approach to manage SSc-pHI.

Abstract
INTRODUCTION Although hemodialysis is lifesaving in patients with kidney failure extensive interdialytic weight gain (IDWG) between dialyses worsens the prognosis. We recently showed a strong correlation between IDWG and predialytic values of cardiac markers. The aim of the present study was to evaluate if the cardiac markers N-terminal pro-B-type natriuretic peptide (proBNP) and troponin T were influenced by IDWG and speed of fluid removal (ultrafiltration-rate). METHODS Twenty hemodialysis patients performed in total 60 hemodialysis (three each). Predialytic values of proBNP and troponin T and changes from predialysis to 180 min hemodialysis (180-0 min) were compared with the IDWG calculated in percent of body weight. The ultrafiltration-rate was adjusted (UF-rateadj ) to IDWG: (100 × weight gain between dialysis [kg])/(estimated body dry weight [kg] × length of hemodialysis session [hours]). RESULTS UF-rateadj correlated (Spearman) with (1) predialytic values of IDWG (r = 0.983, p < 0.001), proBNP (r = 0.443, p < 0.001), and troponin T (r = 0.296, p = 0.025); and (2) differences in proBNP180-0min (r = 0.572, p < 0.001) and troponin T180-0min (r = 0.400, p = 0.002). UF-ratesadj above a breakpoint of 0.60 caused more release of proBNP180-0min (p = 0.027). Remaining variables in multiple regression analysis with ProBNP180-0min as dependent factor were predialytic proBNP (p < 0.001) and the ultrafiltration-rate (p < 0.001). CONCLUSION Higher UF-rateadj during dialysis was correlated to increased levels of cardiac markers. Data support a UF-rateadj lower than 0.6 to limit such increase. Further studies may confirm if limited fluid intake and a lower UF-rateadj should be recommended to prevent cardiac injury during dialysis.

Abstract
Background Myocarditis is a condition that can have severe adverse outcomes and lead to sudden cardiac death if remaining undetected. This study tested the capability of cardiac magnetic field mapping to detect patients with clinically suspected myocarditis. This could open up the way for rapid, non-invasive, and cost-effective screening of suspected cases before a gold standard assessment via endomyocardial biopsy. Methods Historical cardiac magnetic field maps (n = 97) and data from a state-of-the-art magnetocardiography device (n = 30) were analyzed using the Kullback-Leibler entropy (KLE) for dimensionality reduction and topological quantification. Linear discriminant analysis was used to discern between patients with ongoing myocarditis and healthy controls. Results The STT segment of a magnetocardiogram, i.e., the section between the end of the S wave and the end of the T wave, was best suited to discern both groups. Using a 250-ms excerpt from the onset of the STT segment gave a reliable classification between the myocarditis and control group for both historic data (sensitivity: 0.83, specificity: 0.85, accuracy: 0.84) and recent data (sensitivity: 0.69, specificity: 0.88, accuracy: 0.80) using the KLE to quantify the topology of the cardiac magnetic field map. Conclusion The implementation based on KLE can reliably distinguish between clinically suspected myocarditis patients and healthy controls. We implemented an automatized feature selection based on LDA to replace the observer-dependent manual thresholding in previous studies.

Abstract
BACKGROUND Acute decompensated heart failure (ADHF) is a highly prevalent diagnosis in the emergency department and is associated with high morbidity and mortality. As mortality remains high even in patients discharged from the emergency, it becomes mandatory to identify markers predictive of mortality in order to guide the disposition of such patients. No literature is available on the prognostic significance of Troponin I in ADHF patients in an emergency setting from an Indian standpoint. OBJECTIVES This study was aimed at identifying the ability of Troponin I levels at presentation to predict one-month mortality in patients with ADHF. METHODS The study was conducted in the emergency department of a tertiary healthcare center in north India. Serum cardiac Troponin I (cTnI) levels at presentation were assayed in 101 patients and a one-month follow-up was done. RESULTS cTnI levels were > 0.02 ng/mL in 51 patients (50.5%). ROC analysis showed an accuracy of 63% in predicting mortality (p < 0.05). Univariate and multivariate analysis showed an OR of 2.58 and 2.74, respectively (p - 0.037 and 0.047, respectively), suggesting cTnI to be a significant predictor of mortality in ADHF. N-terminal proBNP (NT-proBNP) (OR - 2.09; p - 0.229) and left ventricular ejection fraction (OR - 2.01; p - 0.157) were not found to be significant predictors of mortality on regression analysis. CONCLUSION cTnI levels at presentation are a significant predictor of short-term mortality in ADHF and can be used in an emergency setting to guide treatment, disposition, and follow-up plans of these patients.

Abstract
Heart failure (HF) is a cardiovascular disease defined by several symptoms that occur when the heart cannot supply the blood needed by the tissues. HF, which affects approximately 64 million people worldwide and whose incidence and prevalence are increasing, has an important place in terms of public health and healthcare costs. Therefore, developing and enhancing diagnostic and prognostic sensors is an urgent need. Using various biomarkers for this purpose is a significant breakthrough. It is possible to classify the biomarkers used in HF: associated with myocardial and vascular stretch (B-type natriuretic peptide (BNP), N-terminal proBNP and troponin), related to neurohormonal pathways (aldosterone and plasma renin activity), and associated with myocardial fibrosis and hypertrophy (soluble suppression of tumorigenicity 2 and galactin 3). There is an increasing demand for the design of fast, portable, and low-cost biosensing devices for the biomarkers related to HF. Biosensors play a significant role in early diagnosis as an alternative to time-consuming and expensive laboratory analysis. In this review, the most influential and novel biosensor applications for acute and chronic HF will be discussed in detail. These studies will be evaluated in terms of advantages, disadvantages, sensitivity, applicability, user-friendliness, etc.

Abstract
Left ventricular assist devices (LVADs) have revolutionized the management of patients with advanced heart failure refractory to medical therapy. Current indications of LVADs include Bridge to Transplantation (BTT), Destination Therapy (DT) for long-term use, Bridge to the Decision (BTD) used as a temporary measure, and lastly Bridge to Recovery (BTR). Here, we briefly review the clinical evidence and the molecular mechanisms behind myocardial recovery following LVAD placement. We also share institutional protocols used at 2 major medical centers in the USA.

Abstract
BACKGROUND Cardiomyopathy is the leading cause of death in Duchenne muscular dystrophy (DMD), but studies suggest heart failure biomarkers correlate poorly with cardiomyopathy severity. DMD clinical trials have used troponin I (cTnI) as a biomarker of toxicity, but it is unclear if asymptomatic DMD patients have elevated cTnI. We longitudinally evaluated cTnI, brain natriuretic peptide (BNP), and N-terminal pro-BNP (NT-proBNP) in a DMD cohort. METHODS DMD patients were prospectively enrolled and followed for 3 years. Serum was drawn at the time of cardiac magnetic resonance (CMR). Normal biomarker values were derived from healthy subjects. Biomarkers were correlated with CMR markers. RESULTS All subjects were asymptomatic at the time of enrollment. Several DMD subjects had transiently elevated cTnI. Those with elevated cTnI were more likely to have late gadolinium enhancement on baseline CMR. NT-proBNP correlated with indexed left ventricular end diastolic and maximum left atrial volumes. Otherwise, standard cardiac biomarkers did not correlate with CMR markers of cardiomyopathy. CONCLUSIONS CTnI, BNP, and NT-proBNP do not correlate with CMR assessment of cardiomyopathy progression. A subset of DMD patients have asymptomatic cTnI leak of uncertain clinical significance, though of critical importance if cTnI is used to assess for cardiac toxicity in future drug trials. IMPACT Asymptomatic patients with Duchenne muscular dystrophy (DMD) exhibit transient troponin I leak. NT-proBNP correlated with indexed left ventricular end diastolic volume and indexed maximum left atrial volume. Other cardiac biomarkers did not correlate with cardiac magnetic resonance (CMR) markers of cardiomyopathy.

Abstract
PURPOSE OF REVIEW Cardiovascular disease is the leading cause of death in individuals with chronic kidney disease (CKD). The mechanisms connecting CKD and cardiovascular disease are complex, and serum biomarkers can help improve our understanding. Nt-proBNP and troponin have documented success as biomarkers to diagnose and provide mechanistic insights in non-CKD populations. The purpose of this review is to summarize evidence suggesting efficacy and potential for clinical application of Nt-proBNP and troponin in individuals with CKD. RECENT FINDINGS Our understanding of how Nt-proBNP and Troponin should be interpreted in those with CKD is evolving. Although both biomarkers are in part cleared by the kidney, elevated levels predominantly reflect cardiovascular disease. Both Nt-proBNP and troponin are associated with risk for future cardiovascular events in CKD. Determining CKD-specific cutoffs and using biomarkers to guide therapy remains under active investigation. SUMMARY Of the many serum biomarkers under investigation, Nt-proBNP and troponin best meet the criteria for effective biomarkers in CKD. Assays are widely available and proven to be accurate in CKD populations. Nt-proBNP and troponin deserve special focus in ongoing research of cardiovascular risk reduction in CKD, especially to identify patients at the highest risk, suggest targetable mechanisms and assess treatment efficacy.

Abstract
Cardiac troponin I (cTnI) is a biomarker widely related to acute myocardial infarction (AMI), one of the leading causes of death around the world. Point-of-care testing (POCT) of cTnI not only demands a short turnaround time for its detection but the highest accuracy levels to set expeditious and adequate clinical decisions. The analytical technique Surface-enhanced Raman spectroscopy (SERS) possesses several properties that tailor to the POCT format, such as its flexibility to couple with rapid assay platforms like microfluidics and paper-based immunoassays. Here, we analyze the strategies used for the detection of cTnI by SERS considering POCT requirements. From the detection ranges reported in the reviewed literature, we suggest the diseases other than AMI that could be diagnosed with this technique. For this, a section with information about cardiac and non-cardiac diseases with cTnI release, including their release kinetics or cut-off values are presented. Likewise, POCT features, the use of SERS as a POCT technique, and the biochemistry of cTnI are discussed. The information provided in this review allowed the identification of strengths and lacks of the available SERS-based point-of-care tests for cTnI and the disclosing of requirements for future assays design.

The relationship between day-to-day variability in home blood pressure measurement and multiple organ function. Hypertens Res 2021; 45:474-482. [PMID: 34934161 DOI: 10.1038/s41440-021-00818-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Revised: 11/05/2021] [Accepted: 11/10/2021] [Indexed: 12/18/2022]
Abstract
Blood pressure variability (BPV) is associated with the prognosis of cardiovascular diseases. However, it is unclear how BPV is related to various organs. The aim of this study is to investigate the association between BPV and multiple organ functions. A total of three hundred fifteen participants (114 males; mean age: 70 ± 9 years) participated in a community health checkup held in Tarumizu City. Home blood pressure (BP) was measured using a HEM-9700T (OMRON Healthcare, Kyoto, Japan). Day-to-day BPV was evaluated by the coefficient of variation (CV) of home BP measured in the morning for one month. N-terminal pro B-type natriuretic peptide (NT-pro BNP) and high-sensitivity (hs-)troponin T were measured as cardiac biomarkers. Liver stiffness and renal function were evaluated using the Fibrous-4 (Fib4) index and estimated glomerular filtration rate (eGFR), respectively. NT-pro BNP and hs-troponin T were divided by the median value. Fib4 index greater than 2.67 and eGFR less than 60 mL/min/1.73 m2 were defined as high Fib4 index and low eGFR, respectively. In a multivariable logistic regression analysis, the CV of systolic BP was significantly associated with high NT-pro BNP, high Fib 4 index, and low eGFR, but not with high hs-troponin T. In contrast, the CV of diastolic BP was not associated with low eGFR, and the other three biomarkers had the same results as systolic BP. In conclusion, day-to-day BPV of systolic BP is independently associated with NT-pro BNP, eGFR, and Fib4 index, but not with hs-troponin T. In contrast, diastolic BPV was not found to be associated with eGFR.

Abstract
The importance of lysosomes in cardiac physiology and pathology is well established, and evidence for roles in calcium signaling is emerging. We describe a label-free proteomics method suitable for small cardiac tissue biopsies based on density-separated fractionation, which allows study of endolysosomal (EL) proteins. Density gradient fractions corresponding to tissue lysate; sarcoplasmic reticulum (SR), mitochondria (Mito) (1.3 g/mL); and EL with negligible contamination from SR or Mito (1.04 g/mL) were analyzed using Western blot, enzyme activity assay, and liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis (adapted discontinuous Percoll and sucrose differential density gradient). Kyoto Encyclopedia of Genes and Genomes, Reactome, Panther, and Gene Ontology pathway analysis showed good coverage of RAB proteins and lysosomal cathepsins (including cardiac-specific cathepsin D) in the purified EL fraction. Significant EL proteins recovered included catalytic activity proteins. We thus present a comprehensive protocol and data set of guinea pig atrial EL organelle proteomics using techniques also applicable for non-cardiac tissue.

Abstract
A unique region of human parvovirus B19 virus-VP1 (B19V–VP1u) has been linked to a variety of cardiac disorders. However, the precise role of B19V–VP1u in inducing cardiac injury remains unknown. The present study investigated the effects of B19V–VP1u and different regions of B19V–VP1u, including B19V–VP1uA (residues 1–60), B19V–VP1uB (residues 61–129), B19V–VP1uC (residues 130–195) and B19V–VP1uD (residues 196–227), on inducing cardiac injury in naïve mice by zymography, immunoblotting, H&E staining and cytokine immunoassay. A significantly higher MMP-9/MMP-2 ratio and increased levels of inflammatory cytokines, including IL-6 and IL-1β, were detected in the left ventricles of the mice injected with B19V-non-structural protein 1 (B19V-NS1) and B19V–VP1u, accompanied by increased expression levels of phosphorylated (p-)ERK and p-P38. Significantly upregulated expression levels of atrial natriuretic peptide (ANP), heart-type fatty acid-binding protein (H-FABP) and creatine kinase isoenzyme-MB (CK-MB), which are well-known cardiac injury markers, as well as increased infiltration of lymphocytes, were detected in the left ventricles of the mice injected with B19V–VP1, B19V-NS1 and B19V–VP1u. Moreover, a significantly higher MMP-9/MMP-2 ratio and increased levels of IL-6 and IL-1β were observed in the left ventricles of the mice injected with B19V–VP1u, B19V–VP1u-A, B19V–VP1u-B and B19V–VP1u-C, accompanied by upregulated p-ERK and p-P38 expression. Notably, significantly lower levels of IL-6 and IL-1β were observed in the left ventricles of the mice injected with B19V–VP1uD. Furthermore, significantly increased ANP, H-FABP and CK-MB expression levels were detected in the left ventricles of the mice injected with B19V–VP1u, B19V–VP1u-A and B19V–VP1u-B, along with enhanced infiltration of lymphocytes. Significantly higher serum IL-1β, IL-6, TNF-α and IFN-γ levels were also detected in the mice injected with B19V–VP1u, B19V–VP1u-A and B19V–VP1u-B. To the best of our knowledge, the findings of the present study were the first to demonstrate that the N-terminal region (residues 1–129) of B19V–VP1u induces an increase in the levels of cardiac injury markers, thus providing evidence for understanding the possible functional regions within B19V–VP1u.

Abstract
Objectives This study aimed to investigate the prognostic value of serum prealbumin, N-terminal pro-B-type natriuretic peptide (NT-proBNP), heart type fatty acid binding protein (hFABP), and cardiac troponin I (cTnI) for heart failure and cardiac death in elderly patients. Methods We studied 426 consecutive patients with New York Heart Association classes I to IV who were recruited between February 2014 and 2018. Cardiac mortality was the primary end point. Receiver operator characteristic curves were created to analyze predictive values. Results When prealbumin, NT-proBNP, hFABP, and cTnI were combined, the areas under the receiver operator characteristic curve reached 0.930 and 0.903 for heart failure and cardiac death, respectively. Prealbumin, NT-proBNP, hFABP, and cTnI levels changed differently during therapy in patients in different prognosis groups. These parameters improved in patients who did not develop major adverse cardiovascular events (MACEs), but were unchanged or deteriorated in patients with MACEs. Multivariate Cox regression analysis showed that these parameters were significant independent risk factors for MACEs and cardiac death. Conclusions Our study shows that serum prealbumin, NT-proBNP, hFABP, and cTnI levels are significant prognostic factors for elderly patients with poor cardiac function. These parameters are more accurate for prognosis when used together.

Abstract
The parasitic nematode Trichinella spiralis causes trichinellosis, a serious food-borne parasitic zoonosis worldwide. Infection with T. spiralis may also cause myocarditis. In the present study, we used mouse models to assess the impact of blockage of galectin-receptor interactions by α-lactose on cardiac immunopathology during acute T. spiralis experimental infection. Our data demonstrated that, after T. spiralis infection, blockage of galectin-receptor interactions resulted in cardiac dysfunction detected by transthoracic conventional echocardiography, and increased serum Gal-3 level, a biomarker of myocardial damage. In addition, there were increased eosinophil number in peripheral blood, and increased eosinophil infiltration in the heart and spleen tissues accompanied with increased mRNA levels of eosinophil granule proteins (including eosinophil cationic protein (ECP) and eosinophil peroxidase (EPO)) and IL-5 in these organs; increased cardiac fibrosis accompanied with increased Gal-3 and collagen 1 expressions in the hearts of mice with blockage of galectin-receptor interactions after T. spiralis infection. Correlation analysis showed that significant positive correlations existed between the mRNA levels of Gal-3 and ECP/EPO/eosinophil major basic protein/IL-5/CCL11/CCR3/α-SMA/collagen 1 in the hearts of both T. spiralis-infected mice and T. spiralis-infected mice with blockage of galectin-receptor interactions. Our data suggest that galectin-receptor interactions play a pivotal role during acute T. spiralis infection, and lack of galectin-receptor interactions upregulates Gal-3 which, in turn, leads to elevated heart eosinophil recruitment, exacerbated heart pathology and fibrosis, and heart functional damage.

Abstract
BACKGROUND In patients treated for refractory cardiogenic shock (RCS) following acute myocardial infarction (AMI), predicting successful weaning from veno-arterial extracorporeal membrane oxygenation (VA ECMO) has important implications for decision-making and prognosis. METHODS We performed a retrospective review of adult VA ECMO patients with RCS complicating AMI at our institution from 2010 to 2019. We evaluated use of peak troponin I as a predictor of successful decannulation. RESULTS Sixty-two patients were analyzed; mean age 61.1 ± 9.8 years, 73% males, 62% presented with STEMI. Forty-five patients were successfully weaned (group I). Seventeen patients did not wean (group II); seven patients received a durable LVAD, 10 died. Patients from group I had significantly lower peak troponin I (89 vs 434 ng/mL, p = 0.0001). Receiver operating characteristic curves showed a peak troponin I cutoff of 400 ng/mL correctly classified patients by weaning status 90% of the time, with associated sensitivity of 71% and specificity of 98%. With each 50 ng/mL increase in troponin I, the likelihood of weaning decreased by 33%. CONCLUSIONS Peak troponin I above 400 ng/mL may be helpful in predicting unsuccessful weaning from VA ECMO support for refractory cardiogenic shock following myocardial infarction and facilitate triage decisions regarding need for advanced therapies.

Pentoxifylline Attenuates Arsenic Trioxide-Induced Cardiac Oxidative Damage in Mice. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6406318.

Abstract
This study was undertaken to evaluate the therapeutic potential effect of pentoxifylline (PTX) against arsenic trioxide (ATO)-induced cardiac oxidative damage in mice. Thirty-six male albino mice were divided into six groups and treated intraperitoneally with normal saline (group 1), ATO (5 mg/kg; group 2), PTX (100 mg/kg; group 3), and different doses of PTX (25, 50, and 100 mg/kg; groups 4, 5, and 6, respectively) with ATO. After four weeks, the blood sample was collected for biochemical experiments. In addition, cardiac tissue was removed for assessment of oxidative stress markers and histopathological changes (such as hemorrhage, necrosis, infiltration of inflammatory cells, and myocardial degeneration). The findings showed that ATO caused a significant raise in serum biochemical markers such as lactate dehydrogenase (LDH), creatine phosphokinase (CPK) and troponin-I (cTnI), glucose, total cholesterol (TC), and triglyceride (TG) levels. In addition to histopathological changes in cardiac tissue, ATO led to the significant increase in cardiac lipid peroxidation (LPO) and nitric oxide (NO); remarkable decrease in the activity of cardiac antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx); and the depletion of the total antioxidant capacity (TAC) and total thiol groups (TTGs). PTX was able to reduce the increased levels of serum cardiac markers (LDH, CPK, cTnI, TC, and TG), cardiac LPO, and improve antioxidant markers (TAC, TTGs, CAT, SOD, and GPx) alongside histopathologic changes. However, no significant changes were observed in elevated serum glucose and cardiac NO levels. In conclusion, the current study showed the potential therapeutic effect of PTX in the prevention of ATO-induced cardiotoxicity via reversing the oxidative stress.

Abstract
Myocardial infarction (MI) is the most common cause of a heart failure, which occurs due to myocardial ischemia leading to left ventricular (LV) remodeling. LV remodeling particularly occurs at the ischemic area and the region surrounds it, known as the border zone. The role of the border zone in initiating LV remodeling process urges the investigation on the correlation between early border zone changes and remodeling outcome. Thus, this study aims to simulate a preliminary conceptual work of the border zone formation and evolution during onset of MI and its effect towards early LV remodeling processes by incorporating the oxygen concentration effect on the electrophysiology of an idealized three-dimensional LV through electro-chemical coupled mathematical model. The simulation result shows that the region of border zone, represented by the distribution of electrical conductivities, keeps expanding over time. Based on this result, the border zone is also proposed to consist of three sub-regions, namely mildly, moderately, and seriously impaired conductivity regions, which each region categorized depending on its electrical conductivities. This division could be used as a biomarker for classification of reversible and irreversible myocardial injury and will help to identify the different risks for the survival of patient. Larger ischemic size and complete occlusion of the coronary artery can be associated with an increased risk of developing irreversible injury, in particular if the reperfusion treatment is delayed. Increased irreversible injury area can be related with cardiovascular events and will further deteriorate the LV function over time.

Cardiac troponin T and NT-proBNP as diagnostic and prognostic biomarkers of primary cardiac involvement and disease severity in systemic sclerosis: A prospective study.

Abstract
OBJECTIVES The aim of our study was to define the role of high-sensitive cardiac troponin T (hs-cTnT) and NT-proBNP in identifying Systemic Sclerosis (SSc) patients with cardiac involvement and at higher risk of cardiac death. METHODS Plasma hs-cTnT and NT-proBNP concentrations were measured in 245 SSc-patients. RESULTS hs-cTnT and NT-proBNP levels were higher in SSc-patients than in healthy controls. Hs-cTnT levels were higher than 0.014 ng/ml in 32.3% SSc-patients, while NT-proBNP was above 125 pg/ml in 31.8% of them, irrespective of classical cardiovascular risk factor and of pulmonary arterial hypertension. Elevated hs-cTnT and NT-proBNP were associated with diffuse skin involvement and directly correlated with the skin score. Patients with increased cardiac markers presented a lower left-ventricular ejection fraction (LVEF) and a higher rate of right bundle branch block (RBBB) on electrocardiogram (ECG) compared to patients with normal cardiac enzymes. During the follow-up, 12 SSc-patients experience a disease-related death; 9 of these were directly related to cardiac involvement (sudden cardiac death or heart failure) and the majority of them occurred among patients with increase of at least one cardiac biomarker. Long-term survival was worse in patients with increase of both cardiac biomarkers. CONCLUSIONS Evaluation of hs-cTnT and NT-proBNP levels may provide a tool to screen non-invasively SSc-patients for heart involvement. A higher incidence of impaired systolic function, ECG abnormalities and a poor outcome in SSc-patients with elevated cardiac enzymes suggests that they may be valuable screening biomarkers to detect a cardiac damage at early stages and to improve risk stratification.

Abstract
BACKGROUND Heart Failure (HF) is accompanied by a high cost of care and gloomy prognosis despite recent advances in its management. Therefore, efforts to minimize HF rehospitalizations is a major focus of several studies. METHODS We conducted a retrospective cohort study of 140 patients 18 years and above who had baseline clinical parameters, echocardiography, NT-ProBNP, troponin I and other laboratory parameters following a 3-year electronic medical record review. Patients with coronary artery disease, preserved ejection fraction, pulmonary embolism, cancer, and end-stage renal disease were excluded. RESULTS Of the 140 patients admitted with HF with reduced Ejection Fraction (HFrEF) secondary to non-ischemic cardiomyopathy, 15 were re-hospitalized within 30 days of discharge while 42 were rehospitalized within 6 months after discharge for decompensated HF. Receiver operating characteristic (ROC) cutoff points were obtained for NT-ProBNP at 5178 pg/ml and serum troponin I at 0.045 ng/ml. After Cox regression analysis, patients with HFrEF who had higher hemoglobin levels had reduced odds of re-hospitalization (p = 0.007) within 30 days after discharge. NT-ProBNP and troponin I were independent predictors of re-hospitalization at 6 months after discharge (p = 0.047 and p = 0.02), respectively, after Cox regression analysis. CONCLUSION Troponin I and NT-ProBNP at admission are the best predictors of re-hospitalization 6 months after discharge among patients with HFrEF. Hemoglobin is the only predictor of 30 -day rehospitalization among HFrEF patients in this study. High-risk patients may require aggressive therapy to improve outcomes.

Abstract
BACKGROUND Echocardiography and 24-hour ECG are the gold standard tests to diagnose dilated cardiomyopathy (DCM) in Doberman Pinschers (DP), but myocardial damage might be detected earlier using a high-sensitivity cardiac troponin I (hs-cTnI) assay. OBJECTIVE To evaluate and compare an hs-cTnI assay (Advia Centaur TnI-Ultra assay) with a conventional cTnI assay in DP with different stages of DCM and in healthy DP. ANIMALS Three hundred forty-five examinations from 162 DP with and 179 DP without DCM. METHODS Prospective longitudinal study. Dogs were allocated into 6 groups based on echocardiographic and 24-hour ECG criteria: (1) healthy group (179 dogs), (2) last-normal group (29 dogs), which included dogs that were considered to be healthy at the time of their examination but were assigned to the last-normal group retrospectively when DCM was diagnosed at their next examination within 1.5 years, (3) only arrhythmias (45 dogs, 119 examinations), (4) only echocardiographic changes (24 dogs, 61 examinations), (5) echocardiographic changes with ventricular premature complexes (41 dogs, 100 examinations), and (6) decompensated (23 dogs, 36 examinations). Hs-cTnI and conventional cTnI concentration measurements were performed and compared. RESULTS A cutoff value of hs-cTnI concentration >0.113 ng/mL had a sensitivity of 81.2% and a specificity of 73.2% to identify the presence of DCM. The conventional cTnI assay showed a similar test performance, but the hs-cTnI assay identified more dogs (21/29 dogs, 72%) in the last-normal group compared to the conventional cTnI test (18/29 dogs, 62%). CONCLUSIONS AND CLINICAL IMPORTANCE The hs-cTnI is an additional test with good potential to identify early DCM.

Abstract
Aim: The present study was designed to probe the cardioprotective effects of nanoyttria (NY). Materials & methods: NY was characterized using various techniques. Isoproterenol (ISO)-induced cardiotoxicity challenged mice were treated with NY for 28 days at two doses (0.4 and 4 mg/kg, intraperitoneally). Results: NY demonstrated free radical scavenging activity as shown by a 2,2-diphenyl-1-picrylhydrazyl assay. NY treatment showed alleviation of ISO-induced cardiotoxicity as evident from the reduction in biochemical parameters. The expression of proinflammatory cytokines (IL-1β, IL-6 and TNF-α) showed significant decrease upon NY treatment. Histopathology and ECG showed protection in histoarchitecture and rhythm of heart, respectively. Reduction in hydroxyproline and TGF-β1 expression indicated antifibrotic activity. Conclusion: We report for the first time that NY ameliorates ISO-induced cardiac remodeling.

Abstract
Background Lipid dysregulation is a classical risk factor for cardiovascular disease (CVD), yet scanty evidence existed regarding cardiac lipid metabolism that is directly related to heart damage. Recently, the relationship between dyslipidemia and pro-inflammatory insults has led to further understanding on the CVD-predisposing effects of dyslipidemia. The aims of the present study were to investigate whether high-fat high-cholesterol (HFHC) diet-induced hyperlipidemia would cause heart damage and to study the potential role of local cardiac lipid dysregulation in the occurrence of cellular injury. Methods Male Sprague–Dawley rats were divided into normal chow or HFHC diet groups, and sacrificed after 2 or 4 weeks, respectively. Lipid peroxidation marker level was measured. Lipid parameters in the rat hearts were detected. Cardiac damage was evaluated. Results HFHC diet increased serum levels of cholesterol and free fatty acids (FFAs) and led to systemic oxidative stress and pro-inflammatory status. Cardiac lipid dysregulation, which was characterized by elevated levels of cholesterol and adipocyte (A)- and heart (H)-fatty acid binding proteins (FABPs), occurred after HFHC diet for 4 weeks. Cardiac damage was further evident with elevated circulating H-FABP levels, increased cardiac interstitial fibrosis and the loss of troponin I. Conclusion Our data demonstrated that HFHC diet led to systemic and cardiac lipid dysregulation, accompanied by systemic oxidative and pro-inflammatory stresses, and these may finally cooperate to cause a series of pathological changes of the heart tissue. Our findings suggest that maintenance of lipid regulation may be essential in the prevention of heart damage.

Abstract
Doxorubicin (DOX), an anthracycline-based antibiotic, is regularly used in the management of carcinomas, and haematological malignancies have been downplayed in chemotherapy because of its ability to induce dilated cardiomyopathy (DCM). Dexrazoxane is approved to combat the cardiotoxicity, but limited by its adverse effects. Redox imbalance and reactive oxygen species generation plays major role in DOX-induced cardiotoxicity. Histamine, known to mediate various cardiovascular effects, but nevertheless the role of histamine or its receptors in DOX-induced DCM is remained obscure. Hence, this study is aimed to examine the effect of Famotidine (FAM), a H2 receptor antagonist on DOX-induced DCM in Wistar rats. Myocardial antioxidant status, stress and apoptosis markers, myocardial morphology and function were evaluated as the end points. Treatment with FAM has alleviated DOX doxorubicin-induced cardiotoxicity by reducing oxidative and nitrosative stress evident from lipid peroxidation and total nitrate-to-nitrite ratio, and enhanced the activity of super oxide dismutase. Cardiac stress markers like LDH and Na+-K+ATPase activities as well as CK-MB and Cardiac troponin levels were reduced by FAM treatment. It also normalised the myocardial function as assessed by 2D echocardiography and myocardial index. Treatment imparted anti-apoptotic effect as evident from decrease in myocardial caspase 3 and 9 activity and cleaved PARP expression. Effect of FAM is found to be comparable to the standard ACE inhibitor Captopril (CAP). The results from this study collectively suggest H2 receptor antagonism as a novel therapeutic strategy to impart biochemical, structural and functional improvement indicating its cardio-protective activity.

Minute Myocardial Injury as Measured by High-Sensitive Troponin T Serum Levels Predicts the Response to Intracoronary Infusion of Bone Marrow-Derived Mononuclear Cells in Patients With Stable Chronic Post-Infarction Heart Failure: Insights From the TOPCARE-CHD Registry. Circ Res 2017; 120:1938-1946. [PMID: 28351842 DOI: 10.1161/circresaha.116.309938] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2016] [Revised: 03/16/2017] [Accepted: 03/27/2017] [Indexed: 12/13/2022]
Abstract
RATIONALE Cell-based therapies are a promising option in patients with chronic postinfarction heart failure (ischemic cardiomyopathy [ICM]). However, the responses after intracoronary infusion of autologous bone marrow-derived mononuclear cells (BMCs) are heterogeneous, which may be related to impaired cell retention in patients with ICM. Ischemic injury is associated with upregulation of prototypical chemoattractant cytokines mediating retention and homing of circulating cells. The development of ultrasensitive tests to measure high-sensitive troponin T (hs-TnT) serum levels revealed the presence of ongoing minute myocardial injury even in patients with stable ICM. OBJECTIVE To test the hypothesis that serum levels of hs-TnT correlate with cell retention and determine the response to intracoronary BMC application in patients with ICM. METHODS AND RESULTS About 157 patients with stable ICM and no substantial impairment of kidney function received intracoronary BMC administration. Immediately prior to cell application, hs-TnT levels to measure myocardial injury and NT-proBNP levels as marker of left ventricular wall stress were determined. Patients with elevated hs-TnT were older and had more severe heart failure. Importantly, only patients with elevated baseline hs-TnT≥15.19 pg/mL (upper tertile) demonstrated a significant (P=0.04) reduction in NT-proBNP serum levels (-250 [-1465; 33] pg/mL; relative reduction -24%) 4 months after BMC administration, whereas NT-proBNP levels remained unchanged in patients in the 2 lower hs-TnT tertiles. The absolute decrease in NT-proBNP at 4 months was inversely correlated with baseline hs-TnT (r=-0.27, P=0.001). Finally, retention of intracoronarily infused, 111Indium-labeled cells within the heart was closely associated with hs-TnT levels in patients with chronic ischemic heart failure (P=0.0008, n=10, triple measurements). CONCLUSIONS The extent of ongoing myocardial injury as measured by serum levels of hs-TnT predicts the reduction of NT-proBNP serum levels at 4 months after intracoronary BMC administration in patients with ICM, suggesting that the beneficial effects of BMC application on LV remodeling and wall stress are confined to patients with ongoing minute myocardial injury.

Abstract
Tnnt2, encoding thin-filament sarcomeric protein cardiac troponin T, plays critical roles in heart development and function in mammals. To develop an inducible genetic deletion strategy in myocardial cells, we generated a new Tnnt2:MerCreMer (Tnnt2(MerCreMer/+)) knock-in mouse. Rosa26 reporter lines were used to examine the specificity and efficiency of the inducible Cre recombinase. We found that Cre was specifically and robustly expressed in the cardiomyocytes at embryonic and adult stages following tamoxifen induction. The knock-in allele on Tnnt2 locus does not impact cardiac function. These results suggest that this new Tnnt2(MerCreMer/+) mouse could be applied towards the temporal genetic deletion of genes of interests in cardiomyocytes with Cre-LoxP technology. The Tnnt2(MerCreMer/+) mouse model also provides a useful tool to trace myocardial lineage during development and repair after cardiac injury.

Abstract
BACKGROUND AND PURPOSE The ability of a chronic treatment with indacaterol, a new ultra-long-acting β2 -adrenoceptor agonist, to reverse cardiac remodelling and its effects in combination with metoprolol, a selective β1 -adrenoceptor antagonist, were investigated on myocardial infarction in a rat model of heart failure (HF). EXPERIMENTAL APPROACH We investigated the effects of indacaterol and metoprolol, administered alone or in combination, on myocardial histology, β-adrenoceptor-mediated pathways, markers of remodelling and haemodynamic parameters in a rat model of HF. Five groups of rats were assessed: sham-operated rats; HF rats; HF + indacaterol 0.3 mg·kg(-1) ·day(-1) ; HF + metoprolol 100 mg·kg(-1) ·day(-1) ; HF + metoprolol + indacaterol. All pharmacological treatments continued for 15 weeks. KEY RESULTS Treatment with either indacaterol or metoprolol significantly reduced the infarct size in HF rats. However, the combination of indacaterol and metoprolol reduced the infarct size even further, reduced both BP and heart rate, reversed the decrease in ejection fraction, normalized left ventricular systolic and diastolic internal diameters, normalized the decreased β1 adrenoceptor mRNA expression as well as cardiac cAMP levels and reduced cardiac GPCR kinase 2 expression, compared with the untreated HF group. CONCLUSION AND IMPLICATIONS The results of our study demonstrated an additive interaction between indacaterol and metoprolol in normalizing and reversing cardiac remodelling in our experimental model of HF. The translation of these findings to clinical practice might be of interest, as this combination of drugs could be safer and more effective in patients suffering from HF and COPD.

Abstract
Troponin is a highly sensitive biomarker of myocardial injury and has been used extensively in everyday clinical practice in the community as well as in hospitals for the diagnosis of acute myocardial infarction (AMI) and for risk stratification of patients with acute coronary symptoms. Dynamic elevations in biomarkers (troponin) are considered fundamental to the diagnosis of AMI. Unfortunately, many clinical conditions can cause troponin elevation in the absence of myocardial ischaemia, and elevated levels sometimes pose a diagnostic dilemma. In some cases, inappropriate diagnosis of 'AMI' based primarily on a raised troponin can have a deleterious impact on an individual, including on driving, insurance and other medicolegal matters. An incorrect diagnosis of myocardial infarction can also lead to the oversight of serious life-threatening alternative causes of troponin elevation (e.g. pulmonary embolism). This article discusses the role of troponin in our everyday clinical practice in the ED.

Abstract
Cardiac troponin (cTn) is the primary biomarker for the diagnosis of myocardial necrosis in an acute coronary syndrome (ACS). cTn levels can also be elevated in many other conditions, including heart failure, with significant prognostic value. An elevated cTn level can be found in both acute and chronic heart failure and its presence is believed to be due to multiple different pathophysiological processes. In acute decompensated heart failure (AHF), an elevated cTn level has been repeatedly shown to correlate with increased short- and long-term mortality and, to a lesser extent, readmission rates. These associations have been demonstrated with both I and T isoforms of cTn, as well as when troponin is measured with conventional assays or new high-sense assays. In multimarker models, cTn has repeatedly been found to be an independent predictive variable enhancing prognostic ability of the model. cTn is therefore an important biomarker for prognosis in AHF.

Abstract
A translational safety biomarker for toxic myocardial injury is needed in drug discovery and development. This need reflects the increasing recognition of occurrence of cardiotoxicities, prior lack of preclinical blood biomarkers for toxic cardiac injury, introduction of troponin as a biomarker, and regulatory and industry drivers. Cardiac troponin is considered the gold-standard biomarker in humans for cardiac injury due to ischemic injury and drug toxicity. It has been demonstrated to correlate highly with histopathological extent of injury, degree of impairment of cardiac function, and prognosis. Numerous studies have now clearly demonstrated that both cardiac troponin T and cardiac troponin I are sensitive and specific biomarkers of cardiac injury in laboratory animals. Their use is highly recommended for incorporation into preclinical drug-safety studies, especially whenever there is any history of cardiac effect in prior studies with a compound of the same or similar chemical or pharmacological class. The main caveats with respect to cross-species use of specific cardiac troponin assays are the need for species-specific validation, definition of cut-offs based on relevant assessments of imprecision and reference ranges or concurrent controls, and knowledge of the species-dependent kinetics of release into, and clearance from, the blood. Future development of high-sensitivity assays should determine whether minimal increases below a threshold concentration of troponin might reflect reversible myocardial effects.

Abstract
Aim: To associate the time-course of h-FABP and N-terminal pro B-type natriuretic peptide (NT-proBNP)after left ventricular assist device (LVAD) implantation to outcome in end-stage heart failure patients. Materials & methods: Patients (n = 14, NYHA class III/IV; left ventricular ejection fraction <25% were enrolled; ten survived up to 1 month after LVAD (survivors) and four died of multiorgan failure within 2 weeks (nonsurvivors). Blood samples were obtained at admission; at 4, 24 and 72 h; and at 1 and 4 weeks after LVAD. Results: h-FABP significantly increases after surgery, decreasing since 72 h in all patients. At 72 h all survivor patients present h-FABP lower than the median value. N-terminal pro B-type natriuretic peptide is not associated with patient outcome at any time. Conclusion: High h-FABP levels, indicating the presence of more severe myocardial damage, are associated with a poor prognosis in patients with LVAD, suggesting that an early cardiac injury marker could improve the prediction of clinical outcome.

Abstract
Human dilated cardiomyopathy (DCM) is characterized by congestive heart failure and altered myocardial gene expression. Epigenetic changes, including DNA methylation, are implicated in the development of DCM but have not been studied extensively. Clinical human DCM and nonfailing control left ventricle samples were individually analyzed for DNA methylation and expressional changes. Expression microarrays were used to identify 393 overexpressed and 349 underexpressed genes in DCM (GEO accession number: GSE43435). Gene promoter microarrays were utilized for DNA methylation analysis, and the resulting data were analyzed by two different computational methods. In the first method, we utilized subtractive analysis of DNA methylation peak data to identify 158 gene promoters exhibiting DNA methylation changes that correlated with expression changes. In the second method, a two-stage approach combined a particle swarm optimization feature selection algorithm and a discriminant analysis via mixed integer programming classifier to identify differentially methylated gene promoters. This analysis identified 51 hypermethylated promoters and six hypomethylated promoters in DCM with 100% cross-validation accuracy in the group assignment. Generation of a composite list of genes identified by subtractive analysis and two-stage computation analysis revealed four genes that exhibited differential DNA methylation by both methods in addition to altered gene expression. Computationally identified genes (AURKB, BTNL9, CLDN5, and TK1) define a central set of differentially methylated gene promoters that are important in classifying DCM. These genes have no previously reported role in DCM. This study documents that rigorous computational analysis applied to microarray analysis of healthy and diseased human heart samples helps to define clinically relevant DNA methylation and expressional changes in DCM.

Abstract
Glucose-insulin-potassium (GIK) is a useful adjunct to myocarditis. Besides its essential action in energy metabolism, insulin also exerts an anti-inflammatory effect. This study investigated the effect of insulin on myocardial inflammation in experimental autoimmune myocarditis (EAM) in mice and its potential role in T cell regulation. Mice were divided randomly into a normal control group, a saline-treated EAM group and an insulin-treated EAM group. The histopathological changes of myocardium, α-myosin heavy chain (MyHCα)(614-629) antigen-specific autoantibody titre, the serum level of cardiac troponin I (cTnI), mitogen-activated protein kinase (MAPK) family members' activity and content were measured. Furthermore, the phenotype of T lymphocyte subsets in splenocytes was analysed to evaluate the immune status of mice. Insulin reduced serum cTnI of EAM mice on days 14 and 21 (P < 0·05) after immunization, with no changes in blood glucose and autoantibody production. Western blot revealed that extracellular signal-regulated protein kinase (ERK1/2) may be a determining factor in this process. Total ERK1/2 and phospho-ERK1/2 (p-ERK1/2) were both up-regulated in insulin-treated mice after immunization. We also found that insulin treatment promoted T cell recovery without changing the naive-to-memory T-cell ratio; in particular, CD3(+) T cells in insulin-treated mice proliferated more vigorously than in control mice (P < 0·05). We report here for the first time that insulin alleviates myocarditis in the EAM model. These data show that insulin has a direct effect on T cell proliferation in EAM. It is possible that GIK or insulin may assist T cell recovery towards normal in myocarditis, especially for diabetic or hyperglycaemic patients.

Abstract
The Joint European Society of Cardiology-American College of Cardiology Foundation-American Heart Association-World Heart Federation Task Force for the Redefinition of Myocardial Infarction recommends cardiac troponin (cTn)-T as a first-line biomarker, and suggests the use of the 99th percentile of a reference population with acceptable precision (i.e. a coefficient of variance≤10%) as a cut-off for the diagnosis of acute myocardial infarction. Recently developed troponin assays fulfill this analytical precision. While conventional cTnT assays have often been used as a positive or negative categorical variable, stepwise rises in high sensitivity (Hs)-cTnT in patients presenting with chronic heart failure (HF) have been associated with a progressive increase in the incidence of cardiovascular events. Similar observations have been made in the general population. Hs-cTnT at baseline and during follow-up is a powerful predictor of cardiac events in patients with HF and in the general population. Whether it is the ideal biomarker remains to be confirmed, however. We review the potential contributions of TnT assays in the assessment of risk of HF, in HF, and in myocardial diseases that cause HF.

Abstract
BACKGROUND It can be difficult to predict which patients will survive and recover cardiac function after valve replacement surgery. We hypothesized that the expression levels of ventricular myosin light chain (MLCv) might reflect the severity of disease or the extent of irreversible myocardial damage and might be useful for predicting the postoperative course. Thus, the aim of this study was to explore the relationship between MLCv expression in specimens obtained during valve replacement surgery and the postoperative New York Heart Association (NYHA) class. METHODS The levels of expression of the regulatory MLCv (MLC-2v) and MLC-1v in papillary muscle specimens from 80 patients who underwent valve replacement surgery for rheumatic valvular disease were evaluated by Western blot analysis. RESULTS The patients were similar with regard to the intraoperative expression of MLC-1v, regardless of postoperative NYHA class. The preoperative NYHA class, the end-systolic left ventricular internal dimension, and the intraoperative expression of MLC-2v emerged as independent risks factors for a NYHA class status of III/IV at 6 months after surgery, with an area under the receiver operating characteristic curve of 0.862. CONCLUSION The intraoperative level of MLC-2v expression was predictive of the patients' NYHA class after valve replacement surgery. This result suggests that future studies evaluating the use of preoperative specimens (such as biopsy or peripheral blood samples) for measurement of MLC-2v levels could lead to a valuable preoperative tool for the assessment of candidates for valve replacement.

Abstract
BACKGROUND Cardiac troponin I (cTnI) is a useful biomarker in patients with chronic heart failure (CHF), and a highly sensitive cTnI (hs-cTnI) commercial assay has become available. However, the prognostic role of serial measurements of hs-cTnI in stable outpatients with CHF remains unknown. METHODS At entry to the study, we evaluated 95 stable outpatients with nonischemic CHF showing a serum hs-cTnI (Centaur TnI-Ultra [Siemens Medical Solution Diagnostics, New York, NY], lower limit of detection 0.006 ng/mL) value ≥0.006 ng/mL. To evaluate the role of repetitive measurements of hs-cTnI, we performed echocardiography and measured serum levels of cTnI and N-terminal proBNP at baseline and 6 months later and then prospectively followed up these patients for 4.25 years. RESULTS During long-term follow-up, there were 27 cardiac deaths. On multivariate analyses, high plasma N-terminal pro-brain natriuretic peptide (≥711 pg/mL, P = .0008), high serum hs-cTnI at baseline (≥0.03 ng/mL, P = .0011), and an increase in hs-cTnI (Δhs-cTnI ≥0 ng/mL, P = .022) after 6 months were independent significant prognostic predictors. The hazard ratio for mortality of patients with high hs-cTnI (≥0.03 ng/mL) and an increase in hs-cTnI (Δhs-cTnI ≥0 ng/mL) was 3.59 (95% CI 1.3-9.9, P = .014) compared with that of those with high hs-cTnI (≥0.03 ng/mL) and a decrease in hs-cTnI (Δhs-cTnI <0 ng/mL). CONCLUSIONS These findings indicated that not only the serum concentration of hs-cTnI at baseline but also an increase in hs-cTnI were independent and useful prognostic predictors in patients with nonischemic CHF.
