The prognostic significance of heart-type fatty acid binding protein in patients with stable coronary heart disease

Markers of cardiac injury in patients with liver cirrhosis

Liver cirrhosis is an increasing public health problem and a major cause of morbidity and mortality. Accordingly, cirrhotic cardiomyopathy, a frequently underdiagnosed condition, is becoming a growing health problem. In the last 20 years, cardioselective biomarkers have been investigated for their diagnostic and prognostic properties for numerous conditions. The aim of this article is to review the literature on the relationship between the most commonly used cardioselective biomarkers (cardiac troponins I and T, N-terminal pro-B-type natriuretic peptide, brain natriuretic peptide, and heart-type fatty-acid binding protein) and the presence, functional stage, and clinical outcomes of liver cirrhosis. Elevated plasma levels of these biomarkers have been reported in patients with liver cirrhosis, and there is mounting evidence on their predictive value for clinical outcomes in this disease. In addition, elevated plasma levels of these biomarkers have been reported in patients before, during, and after liver transplantation, but in fewer studies. Due to their predictive value for clinical outcomes, we advocate the use of these markers in patients with liver cirrhosis and cirrhotic cardiomyopathy, as well as in candidates for liver transplant.

The clinical significance of osteopontin on the cardiovascular outcomes in patients with stable coronary artery disease

BACKGROUND

Osteopontin (OPN) is a noncollagenous matricellular protein which is mainly present in bone matrix. A high OPN level has been associated with heart failure and acute coronary syndrome, however data on patients with chronic coronary syndrome (CCS) are lacking. The present study aimed to evaluate the association between OPN and the prognosis of Taiwanese patients with CCS.

METHODS

We enrolled participants from the Biosignature Registry, a nationwide prospective cohort study conducted at nine different medical centers throughout Taiwan. The inclusion criteria were participants who had received successful percutaneous coronary intervention at least once previously, and stable under medical therapy for at least 1 month before enrollment. They were followed for at least 72 months. Logistic regression and Cox proportional hazard model were used to investigate the association between OPN and clinical outcomes. The outcomes of this study were the first occurrence of hard cardiovascular events and composite cardiovascular outcomes including cardiovascular mortality, revascularization, hospitalization for acute myocardial infarction (AMI) or heart failure.

RESULTS

A total of 666 patients with both hs-CRP and osteopontin measurements were enrolled and followed for 72 months. OPN was correlated positively with AMI-related hospitalization, where the highest tertile (Tertile 3) of baseline OPN had the highest risk of AMI-related hospitalization, which remained significant after multivariate adjustments (HR 3.20, p = 0.017). In contrast, combining OPN and hs-CRP did not improve the prediction of CV outcomes.

CONCLUSION

OPN may be a potentially valuable biomarker in predicting CV outcomes. During 6 years of follow-up period, an OPN level >4810 pg/ml was associated with a significantly higher incidence of AMI-related hospitalization in CCS patients who received successful PCI before the enrollment.

Cerebrospinal fluid levels of fatty acid-binding protein 3 are associated with likelihood of amyloidopathy in cognitively healthy individuals

INTRODUCTION

Fatty acid-binding protein 3 (FABP3) is a biomarker of neuronal membrane disruption, associated with lipid dyshomeostasis-a notable Alzheimer's disease (AD) pathophysiological change. We assessed the association of cerebrospinal fluid (CSF) FABP3 levels with brain amyloidosis and the likelihood/risk of developing amyloidopathy in cognitively healthy individuals.

METHODS

FABP3 levels were measured in CSF samples of cognitively healthy participants, > 60 years of age (n = 142), from the Australian Imaging, Biomarkers & Lifestyle Flagship Study of Ageing (AIBL).

RESULTS

FABP3 levels were positively associated with baseline brain amyloid beta (Aβ) load as measured by standardized uptake value ratio (SUVR, standardized β = 0.22, P = .009) and predicted the change in brain Aβ load (standardized β = 0.32, P = .004). Higher levels of CSF FABP3 (above median) were associated with a likelihood of amyloidopathy (odds ratio [OR] 2.28, 95% confidence interval [CI] 1.12 to 4.65, P = .023).

DISCUSSION

These results support inclusion of CSF FABP3 as a biomarker in risk-prediction models of AD.

The prognostic significance of the presence of tenascin-C in patients with stable coronary heart disease

BACKGROUND

We investigated the prognostic value of tenascin-C in patients with stable coronary heart disease.

METHODS

A total of 666 patients were enrolled and followed for 72 months. The primary outcome was a composite of cardiac events. The secondary outcomes were all-cause death, cardiovascular death, acute myocardial infarction (AMI), and heart failure hospitalization.

RESULTS

The area under the curve of tenascin-C to discriminate the occurrence of composite cardiac events was 70 % (95 % CI: 64.2 % to 75.8 %), and the corresponding optimal cutoff value was 19.91 ng/ml. A higher concentration of tenascin-C was associated with a greater risk of composite cardiac events (P trend < 0.001). Similar results were observed in all-cause death, AMI, and heart failure hospitalization.

CONCLUSION

Tenascin-C was found to be an independent predictor of total cardiovascular events in patients with stable coronary heart disease at 72 months, and also for all-cause death, AMI, and heart failure hospitalization.

From Classic to Modern Prognostic Biomarkers in Patients with Acute Myocardial Infarction

Despite all the important advances in its diagnosis and treatment, acute myocardial infarction (AMI) is still one of the most prominent causes of morbidity and mortality worldwide. Early identification of patients at high risk of poor outcomes through the measurement of various biomarker concentrations might contribute to more accurate risk stratification and help to guide more individualized therapeutic strategies, thus improving prognoses. The aim of this article is to provide an overview of the role and applications of cardiac biomarkers in risk stratification and prognostic assessment for patients with myocardial infarction. Although there is no ideal biomarker that can provide prognostic information for risk assessment in patients with AMI, the results obtained in recent years are promising. Several novel biomarkers related to the pathophysiological processes found in patients with myocardial infarction, such as inflammation, neurohormonal activation, myocardial stress, myocardial necrosis, cardiac remodeling and vasoactive processes, have been identified; they may bring additional value for AMI prognosis when included in multi-biomarker strategies. Furthermore, the use of artificial intelligence algorithms for risk stratification and prognostic assessment in these patients may have an extremely important role in improving outcomes.

Novel Biomarkers of Kidney Disease in Advanced Heart Failure: Beyond GFR and Proteinuria

PURPOSE

Kidney disease is a common finding in patients with heart failure and can significantly impact treatment decisions and outcomes. Abnormal kidney function is currently determined in clinical practice using filtration markers in the blood to estimate glomerular filtration rate, but the manifestations of kidney disease in the setting of heart failure are much more complex than this. In this manuscript, we review novel biomarkers that may provide a more well-rounded assessment of kidney disease in patients with heart failure.

RECENT FINDINGS

Galectin-3, ST2, FGF-23, suPAR, miRNA, GDF-15, and NAG may be prognostic of kidney disease progression. L-FABP and suPAR may help predict acute kidney injury (AKI). ST2 and NAG may be helpful in diuretic resistance. Several biomarkers may be useful in determining prognosis of long-term kidney disease progression, prediction of AKI, and development of diuretic resistance. Further research into the mechanisms of kidney disease in heart failure utilizing many of these biomarkers may lead to the identification of therapeutic targets.

Cardiovascular Biomarkers: Lessons of the Past and Prospects for the Future

Cardiovascular diseases (CVDs) are a major healthcare burden on the population worldwide. Early detection of this disease is important in prevention and treatment to minimise morbidity and mortality. Biomarkers are a critical tool to either diagnose, screen, or provide prognostic information for pathological conditions. This review discusses the historical cardiac biomarkers used to detect these conditions, discussing their application and their limitations. Identification of new biomarkers have since replaced these and are now in use in routine clinical practice, but still do not detect all disease. Future cardiac biomarkers are showing promise in early studies, but further studies are required to show their value in improving detection of CVD above the current biomarkers. Additionally, the analytical platforms that would allow them to be adopted in healthcare are yet to be established. There is also the need to identify whether these biomarkers can be used for diagnostic, prognostic, or screening purposes, which will impact their implementation in routine clinical practice.

Prognostic indicators for the onset of ischaemic versus haemorrhagic stroke in stable coronary artery disease

The incidence of stroke may be increased in patients with coronary artery disease (CAD). We aimed to investigate the specific risk factors for the development of ischaemic and haemorrhagic stroke in stable CAD patients.Patients with stable CAD were prospectively enrolled for future cardiovascular events in Taiwan. All the patients had received coronary interventions and were stable for least 1 month before enrolment. The incidence of ischaemic stroke was identified and confirmed by telephone and hospital records. Baseline characteristics, including demographic data, lipid profiles, medications, and biomarkers for potential inflammatory and atherosclerosis, were analysed.In total, 1428 patients (age, 63.07 ± 11.4 years; 1207 males) were under standard medical treatment and regularly followed-up for at least 4 years. Multivariate logistic regression analysis showed that baseline serum myeloperoxidase (MPO) level (hazard ratio [HR]: 1.89, 95% CI: 1.16-3.10, P = .01) and statin use (HR: 0.37; 95% CI: 0.17-0.79, P = .01) were independently associated with the onset of ischaemic stroke. Age (HR: 1.07, 95% CI: 1.00-1.14, P = .04) and angiotensin receptor blocker (ARB) use (HR: 0.37, 95% CI: 0.17-0.79, P = .01) were independently associated with future onset of intracranial haemorrhage (ICH), implying the different mechanisms of ischaemic stroke and ICH.Age and ARB use were related to ICH onset. Baseline MPO level and statin use were independently associated with longer and shorter future ischaemic stroke onset in stable CAD patients, respectively. Further studies are indicated to confirm the potential mechanisms and advance individual risk stratification for the onset of different types of stroke in clinical CAD.

[New cardiac biomarkers for early detection of myocardial infarction in cardiac surgery]

In-hospital mortality after cardiac surgery ranges from 2% to 8%. Many patients suffer from major adverse cardiovascular events, e.g. myocardial infarction, which in the long term can result in severe limitations in routine activities. Troponin plays the central role in identifying myocardial infarction; however, interpretation after cardiac surgery is difficult due to ischemia reperfusion injury and direct surgical trauma. Thus, the distinction between procedure-related myocardial injury and additional myocardial injury due to a new event is difficult. The fourth universal definition of type 5 myocardial infarction uses the 10 × upper limit of normal (ULN) as cut-off and notably > 90% of patients after on-pump procedures exceed this cut-off. Clinical consequences are mostly unclear. The dynamics of copeptin and heart-type fatty acid binding protein (H-FABP) concentrations start very early, i.e. several hours before troponin. The characteristics of copeptin and H‑FABP might help to overcome the limitations of troponin. This short narrative review gives a concise overview on this topic. Moreover, a brief view of future perspectives in this field is given.

Promising Novel Biomarkers in Cardiovascular Diseases

Cardiovascular diseases remain the most common causes of death globally, according to the World Health Organization. In recent years, a great number of biomarkers have been investigated, whereas only some have gained value in the diagnosis, prognosis, and risk stratification of different cardiovascular illnesses. As numerous studies have investigated the diagnostic yield of novel biomarkers in various disease entities every year, this review aims to provide an overview of the current status of four promising representatives. In particular, this manuscript refers to soluble suppression of tumorigenicity 2 (sST2), heart-type fatty acid binding protein (H-FABP), growth differentiation factor (GDF-15) and soluble urokinase-type plasminogen activator receptor (suPAR). These markers are of special interest as they are thought to provide an accurate estimate of cardiovascular risk in certain patient populations, especially those with pre-existing diseases, such as obesity or diabetes mellitus. We sought to give an overview of their function, individual diagnostic and predictive value and determination in the laboratory. A review of the literature regarding the aforementioned cardiovascular biomarkers yielded manifold results with respect to their individual diagnostic and prognostic value. Yet, the clinical relevance of these findings remains unclear, warranting further studies to identify their optimal use in clinical routine.

Heart-type fatty acid binding protein predicts cardiovascular events in patients with stable coronary artery disease: a prospective cohort study

Background

Heart-type fatty acid binding protein (H-FABP) has been reported to be a prognostic predictor for cardiovascular outcome in acute coronary syndrome (ACS). However, its prognostic utility in patients with stable coronary artery disease (CAD) has not been well established. The aim of this study was to assess the association between H-FABP with the severity of coronary disease and cardiovascular events (CVEs) in patients with stable CAD.

Methods

A total of 4,370 angiography-proven CAD patients were consecutively enrolled. The severity of CAD was assessed by Gensini Score (GS) and the numbers of diseased vessels. The CVEs included cardiovascular death, myocardial infarction, stroke and coronary revascularization. Cox regression analysis with adjusted hazard ratios (HRs) and Kaplan-Meier analysis were used to evaluate the relation of H-FABP to CVEs in this cohort.

Results

During a median follow-up of 51 months, 353 CVEs occurred. Overall, patients in the highest levels of H-FABP group had increased rate of multi-vessel stenosis and higher GS compared with those in the lowest group (P<0.05, respectively). Moreover, H-FABP levels were significantly higher in patients with events compared to those without (P<0.001). In Cox regression analysis, elevated H-FABP levels were found to be independently associated with a high risk of CVEs [adjusted HRs: 1.453; 95% confidence intervals (CIs): 1.040–2.029, P=0.028], especially with cardiovascular death (adjusted HRs: 2.865; 95% CI: 1.315–6.243, P=0.008).

Conclusions

Our results demonstrated that H-FABP was also a useful predictor for CVEs in patients with stable CAD, which needed to be verified by further studies.

H-FABP: A beacon of hope for prediabetic heart disease

Background:

Prediabetes is increasingly being studied in the context of its association with cardiovascular disease (CVD). Besides raised HbA1c and sugar levels, the major underlying defect seems to be insulin resistance (IR). Subclinical atherosclerosis, measured by high sensitivity C reactive protein (hsCRP) and carotid artery intima media thickness (CIMT) underlies the pathogenesis of CVD in prediabetes. Heart-type fatty acid binding protein (H-FABP), a novel cardiac biomarker also might have a role in predictin prediabetic heart disease.

Aims:

The aim of the study is to compare serum levels of H-FABP in prediabetics and controls and correlate them with the atherosclerotic markers, hsCRP and CIMT.

Setting and Design:

50 prediabetic patients and 50 age, sex and BMI matched controls were employed in the case control study. Serum F & PPBS, (HbA1c), fasting insulin levels were measured in cases and controls. Serum H-FABP was measured in both cases and controls. All cases and controls were subjected to bilateral CIMT measurements and Serum hsCRP levels. The values were compared between both the groups and subjected to appropriate statistical analysis.

Statistical Analysis Used:

Categorical variables were presented in number and percentage (%) and continuous variables were presented as mean ± SD and median. Normality of data was tested by Kolmogorov-Smirnov test. If the normality was rejected then non parametric test was used. Quantitative variables were compared using Independent t test/Mann-Whitney Test (when the data sets were not normally distributed) between the two groups. Qualitative variables were correlated using Chi-Square test/Fisher's Exact test. Spearman rank correlation coefficient was used to find out the correlation of various parameters with each other. Univariate linear regression was used to find out the cause and effect relationship between various parameters. A p <0.05 was considered statistically significant. The data analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0.

Results:

The mean serum levels of H-FABP among cases and controls were 6.38± 2.76ng/ml and 3.24 ± 2.47 ng/ml respectively (p <0.0001). Mean CIMT was found to be higher in prediabetics (0.59 ± 0.11 mm ) compared to controls (0.45 ± 0.07mm) (p<0.0001). Serum hsCRP levels were also statistically higher in prediabetics (5.75± 4.16 mg/l) then that of controls (1.86± 1.67 mg/l) (p <0.0001). The correlations of the two variables, hsCRP and CIMT with H-FABP were both strongly positive (r = 0.687) & (r = 0.779) respectively [both cases (p < 0.0001)].

Conclusion:

The novel cardiac biomarker H-FAPB might be a good predictor of cardiovascular risks in prediabetics.

Association of Biomarker Level with Cardiovascular Events: Results of a 4-Year Follow-Up Study

Background

Given the high rates of morbidity and mortality from cardiovascular disease (CVD), the primary and secondary CVD prevention is one of the public health priority. Inflammation and endothelial dysfunction are the major drivers of atherosclerosis development and progression. In this regard, the study of the biomarker application as a tool to better identify high-risk individuals is an up-to-date sector of modern cardiology. The simultaneous measurement of multiple biomarkers can increase the risk stratification for people who are not known to have cardiovascular events in their history. The study aimed to investigate the predictive value of chemokine (C-X-C motif) ligand 16 (CXCL16), endocan, and heart-type fatty acid binding protein (H-FABP) in the cardiovascular event development in people who are not known to have cardiovascular events in their history.

Method

We examined 363 people aged 30 to 65 who have been living permanently in the city of Saran, Karaganda region. The selected participants were people registered at a clinic at the city of Saran, who were screened between August and September 2014.

Results

The follow-up period was 48 months (from August-September 2014 to November 2018). The results showed that CXCL16 (p < 0.001), endocan (p < 0.001), and H-FABP (p=0.002) biomarker levels are significantly higher in outcome groups compared with those of the no-outcome group. Univariate regression analysis proved the prognostic significance of all biomarkers in cardiovascular events development. The multivariate regression analysis after the adjustment confirmed that the CXCL16 increase was associated with the "composite endpoint" (CE) development (p < 0.001) while the endocan increased due to the development of major cardiovascular events (MACE) (p=0.008); we did not find the association of the risks of event development with the H-FABP level increase (p=0.83).

Biomarkers in heart failure: the past, current and future

Despite the enhanced knowledge of the pathophysiology of heart failure (HF), it still remains a serious syndrome with substantial morbidity, mortality, and frequent hospitalizations. These are due to the current improvements in other cardiovascular diseases (like myocardial infarction), the aging population, and growing prevalence of comorbidities. Biomarker-guided management has brought a new dimension in prognostication, diagnosis, and therapy options. Following the recommendation of natriuretic peptides (B-type natriuretic peptide and N-terminal-proBNP), many other biomarkers have been thoroughly studied to reflect different pathophysiological processes (such as fibrosis, inflammation, myocardial injury, and remodeling) in HF and some of them (like cardiac troponins, soluble suppression of tumorigenesis-2, and galectin 3) have subsequently been recommended to aid in the diagnosis and prognostication in HF. Consequently, multi-marker approach has also been approved owing to the varied nature of HF syndrome. In this review, we discussed the guidelines available for HF biomarkers, procedures for evaluating novel markers, and the utilities of both emerging and established biomarkers for risk stratification, diagnosis, and management of HF in the clinics. We later looked at how the rapidly emerging field-OMICs, can help transform HF biomarkers discoveries and establishment.

Potential impacts of high-sensitivity creatine kinase-MB on long-term clinical outcomes in patients with stable coronary heart disease

This study aimed to investigate the prognostic value of high-sensitivity creatine kinase-myocardial band or fraction (hsCK-MB) in comparison with other well-established biomarkers including heart type-fatty acid binding protein (H-FABP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with stable coronary heart disease (SCHD). A total of 1,785 patients were enrolled and followed for 36 months. The primary outcome was all-cause mortality. The secondary outcomes included cardiovascular (CV) death, acute myocardial infarction (AMI), angina-related hospitalizations, and hospitalizations for heart failure. The all-cause mortality rate was significantly higher in the high hsCK-MB group compared to the low hsCK-MB group (4.64% vs. 1.88%, p = 0.0026). After adjusting for baseline covariates, there were no significant differences for the secondary outcomes. H-FABP (≥4.226 ng/mL) was the best predictor for all-cause mortality (HR = 2.68, 95% CI = 1.28-5.62, p = 0.009) and CV death (HR = 6.84, 95% CI = 1.89-22.14, p = 0.003). The high NT-proBNP group had a higher AMI-related hospitalization rate (HR = 1.91, 95% CI = 1.00-3.65, p = 0.05). Neither the addition of hsCK-MB to any other markers nor combinations of the three markers improved the prognostic significance of CV outcomes. In conclusion, hsCK-MB was an independent predictor for all-cause mortality but not CV outcomes in patients with SCHD. Combination of hsCK-MB, H-FABP and NT-proBNP failed to improve the prognostic power for all-cause mortality or CV outcomes.

Heart-Type Fatty Acid-Binding Protein (H-FABP) and its Role as a Biomarker in Heart Failure: What Do We Know So Far?

BACKGROUND

Heart failure (HF) remains one of the leading causes of death to date despite extensive research funding. Various studies are conducted every year in an attempt to improve diagnostic accuracy and therapy monitoring. The small cytoplasmic heart-type fatty acid-binding protein (H-FABP) has been studied in a variety of disease entities. Here, we provide a review of the available literature on H-FABP and its possible applications in HF. Methods: Literature research using PubMed Central was conducted. To select possible studies for inclusion, the authors screened all available studies by title and, if suitable, by abstract. Relevant manuscripts were read in full text.

RESULTS

In total, 23 studies regarding H-FABP in HF were included in this review.

CONCLUSION

While, algorithms already exist in the area of risk stratification for acute pulmonary embolism, there is still no consensus for the routine use of H-FABP in daily clinical practice in HF. At present, the strongest evidence exists for risk evaluation of adverse cardiac events. Other future applications of H-FABP may include early detection of ischemia, worsening of renal failure, and long-term treatment planning.

The effect of crocetin supplementation on markers of atherogenic risk in patients with coronary artery disease: a pilot, randomized, double-blind, placebo-controlled clinical trial

BACKGROUND AND PURPOSE

Molecular mechanisms of atherogenesis are considered to be emerging therapeutic targets for atherosclerosis prevention. Cell and animal studies have shown that crocetin can decelerate atherogenesis. However, the anti-atherogenic properties of crocetin in humans are still ambiguous.

METHODS AND RESULTS

Fifty clinically diagnosed CAD patients were randomly divided into two parallel groups, crocetin and placebo, who received one capsule of crocetin (10 mg) and placebo per day, respectively, for two months. Serum circulating homocysteine (Hcy) [-1.09 (-1.64 to -0.54) μM, P = 0.001], heart-type fatty acid binding protein (h-FABP) [-2.07 (-2.72 to -1.43) ng mL^-1, P = 0.001], intercellular adhesion molecule 1 [-14.92 (-21.92 to -7.92) ng mL^-1, P = 0.001], vascular cell adhesion molecule 1 [-18.61 (-29.73 to -7.49) ng mL^-1, P = 0.002], and monocyte chemoattractant protein 1 [-4.67 (-6.50 to -2.83) pg mL^-1, P = 0.001] decreased significantly after the trial in the crocetin group, while high-density lipoprotein (HDL) significantly increased [+4.21 (0.68 to 7.73) mg mL^-1, P = 0.021]. Also, systolic [-0.21 (-0.32 to -0.10) mmHg, P = 0.001] and diastolic [-0.20 (-0.34 to -0.07) mmHg, P = 0.004] blood pressures decreased significantly in the crocetin group. Nevertheless, clinically significant percentage changes were only observed in Hcy (-15.25 ± 3.15, μM), HDL (-10.70 ± 5.06, mg dL^-1), and h-FABP (-21.10 ± 3.09, ng mL^-1) in the crocetin group. Furthermore, the relative increase in the gene expressions of sirtuin1 and AMP-activated protein kinase and a decrease in the lectin-type oxidized LDL receptor 1 and nuclear factor-kappa B expression in isolated peripheral blood mononuclear cells in the crocetin group were significant at the end of the trial in comparison with the placebo.

CONCLUSION

As the first human study, we showed the ability of crocetin to alter the expression of atherogenic genes and endothelial cell adhesion molecules in CAD patients. It appears that crocetin could be considered as a promising anti-atherogenic candidate for future studies.

Circulating TNFSF14 (Tumor Necrosis Factor Superfamily 14) Predicts Clinical Outcome in Patients With Stable Coronary Artery Disease

Objective—

Basic research indicates that TNFSF14 (tumor necrosis factor superfamily 14) may be involved in the pathogenesis of atherosclerosis. Given the requirements of new biomarkers for risk classification in coronary artery disease (CAD), we conducted a longitudinal analysis to investigate if TNFSF14 levels are associated with the risk of cardiovascular events among patients with stable CAD.

Approach and Results—

In total, 894 patients with CAD were enrolled in a multicenter prospective study. The primary outcome was the occurrence of cardiovascular death, nonfatal myocardial infarction, and stroke. The secondary outcome was the occurrence of all-cause death, nonfatal myocardial infarction, stroke, revascularization, and hospitalization because of angina or heart failure. During the mean follow-up period of 22±9 months, 32 patients reached the primary outcome and 166 patients reached the secondary outcome. Kaplan-Meier analysis showed that the event-free survival was significantly different in the first and fourth quartile groups in subjects categorized by TNFSF14 levels. In multivariate Cox proportional hazard regression analysis, TNFSF14 was independently associated with the risk of cardiovascular events after adjustment for various relevant factors (adjusted hazard ratio, 1.14; 95% CI, 1.04–1.25). In the validation cohort of 126 multivessel patients with CAD, TNFSF14 was confirmed to provide good prognostic predictive value for composite cardiovascular events (adjusted hazard ratio, 1.11; 95% CI, 1.04–1.19).

Conclusions—

This is the first study to demonstrate that increased TNFSF14 levels were independently associated with the occurrence of cardiovascular events in patients with stable CAD. Future studies are worthy to validate if TNFSF14 could be a novel prognostic biomarker for CAD outcomes over different populations.
