Systematic review with meta-analysis: Steatosis severity and subclinical atherosclerosis in metabolic dysfunction-associated steatotic liver disease. Aliment Pharmacol Ther 2024; 59:445-458. [PMID: 38186044 DOI: 10.1111/apt.17869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 11/28/2023] [Accepted: 12/25/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent liver condition recognised as an independent risk factor for cardiovascular disease (CVD). However, there is ongoing debate regarding the effective strategy for cardiovascular risk assessment in MASLD. AIM To investigate the relationship between liver imaging, specifically focusing on the severity of steatosis and subclinical atherosclerosis. METHODS We conducted a thorough search across four databases, from 1950 to April 2023, to identify eligible studies employing imaging to explore the relationship between different degrees of steatosis and subclinical atherosclerosis among MASLD. Additionally, we conducted a quality assessment using the Newcastle Ottawa Scale, performed a meta-analysis employing the DerSimonian-Liard random-effects model, and conducted subgroup analyses for validation. RESULTS In total, 19 studies, encompassing 147,411 middle-aged individuals without previous CVD (74.94% male; mean age 45.53 years [SD 10.69]; mean BMI 24.3 kg/m2 [SD 3.35]), were included. The pooled odds ratio for subclinical atherosclerosis was 1.27 (95% CI: 1.13-1.41, I2 = 76.68%) in mild steatosis and significantly increased to 1.68 (95% CI: 1.41-2.00, I2 = 89.02%) in moderate to severe steatosis. Sensitivity analysis, focusing on high-quality studies, consistently supported this finding and the results remained robust across subgroup analyses. Furthermore, meta-regression revealed that a higher mean AST and ALT, alongside a lower mean HDL, were significant moderators of this association. CONCLUSIONS Even mild steatosis is associated with CVD risk, and steatosis severity further intensifies this association. These findings suggest that liver fat quantification enhances CVD risk stratification in patients with MASLD.

Abstract
INTRODUCTION Fatty liver diseases (FLD), especially defined as metabolic dysfunction-associated FLD (MAFLD), is of growing importance for patients and health-care providers. Extrahepatic comorbidities, predominantly coronary artery disease (CAD), contribute to excess morbidity and mortality in FLD. Although the association of FLD and CAD is well known, underlying pathophysiological links are not fully understood. Non-invasive means of liver diagnostic enable a fast and thorough characterization of FLD. We therefore assessed the severity of FLD in a cohort of patients at risk of CAD. METHODS Patients scheduled for coronary angiography were characterized by anthropometry, serum-based indices of liver fibrosis (NFS, FIB4), abdominal ultrasound and vibration controlled transient elastography (VCTE) including controlled attenuation parameter (CAP) and the Fibroscan-AST (FAST) score. Patients were stratified according to indication of therapeutic coronary intervention. RESULTS 120 patients were recruited, MAFLD was found in 41%, while advanced fibrosis or cirrhosis were present in only 5%. Coronary vascular intervention was indicated in 42% (n = 50). Severity of steatosis assessed by CAP and risk of fibrosis defined by elevated liver stiffness (VCTE>8 kPa) and fibrosis indices were associated with the need for coronary intervention. FAST score, a marker of fibrotic steatohepatitis, was elevated in the intervention group (0.22 vs. 0.12, p<0.001). Multivariate regression analysis revealed FAST score as strongest predictor of CAD (OR 2.3 95%, CI 1.40-2.96). DISCUSSION MAFLD is a frequent comorbidity in patients at CAD risk, but advanced liver disease has a low prevalence in patients undergoing elective coronary angiography. Therefore, a routine VCTE-based screening for FLD cannot be recommended in cardiac patients. The association of indicators of steatohepatitis with advanced CAD points to inflammatory processes as a conjoint mechanism of both diseases.

Abstract
Metabolism-associated fatty liver disease (MAFLD) is a multifaceted disease that involves complex interactions between various organs, including the gut and heart. It is defined by hepatic lipid accumulation and is related to metabolic dysfunction, obesity, and diabetes. Understanding the intricate interplay of the gut-liver-heart crosstalk is crucial for unraveling the complexities of MAFLD and developing effective treatment and prevention strategies. The gut-liver crosstalk participates in the regulation of the metabolic and inflammatory processes through host-microbiome interactions. Gut microbiota have been associated with the development and progression of MAFLD, and its dysbiosis contributes to insulin resistance, inflammation, and oxidative stress. Metabolites derived from the gut microbiota enter the systemic circulation and influence both the liver and heart, resulting in the gut-liver-heart axis playing an important role in MAFLD. Furthermore, growing evidence suggests that insulin resistance, endothelial dysfunction, and systemic inflammation in MAFLD may contribute to an increased risk of cardiovascular disease (CVD). Additionally, the dysregulation of lipid metabolism in MAFLD may also lead to cardiac dysfunction and heart failure. Overall, the crosstalk between the liver and heart involves a complex interplay of molecular pathways that contribute to the development of CVD in patients with MAFLD. This review emphasizes the current understanding of the gut-liver-heart crosstalk as a foundation for optimizing patient outcomes with MAFLD.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome (MetS) and has been correlated with coronary atherosclerosis (CAS). Since NAFLD was renamed metabolic-associated fatty liver disease(MAFLD) in 2020, no studies have evaluated the correlation between MAFLD and CAS. The aim of this study was to evaluate the relationship between MAFLD and CAS. A total of 1330 patients underwent continuous coronary computed tomography angiography (CCTA) and abdominal ultrasound as part of a routine physical examination. Ultrasonography was used to assess fatty liver, and CCTA was used to assess coronary artery plaques, degree of stenosis, and diseased blood vessels. Univariate and multivariate logistic regression analyses were performed with plaque type and degree of stenosis as dependent variables and MAFLD and traditional cardiovascular risk factors as independent variables to analyze the correlation between MAFLD and CAS. Among the 1164 patients, 680 (58.4%) were diagnosed with MAFLD through a combination of ultrasound and auxiliary examinations. Compared with the non-MAFLD group, the MAFLD group had more cardiovascular risk factors,and the MAFLD group had more likely to have coronary atherosclerosis, coronary stenosis and multiple coronary artery stenosis.In the univariate logistic regression, MAFLD was significantly correlated with overall plaque, calcified plaques, noncalcified plaques, mixed plaques,and significant stenosis in the coronary arteries.(p < 0.05). After adjusting for cardiovascular risk factors , MAFLD was correlated with noncalcified plaques (1.67; 95% confidence interval (CI) 1.15-2.43; p = 0.007) and mixed plaques (1.54; 95% CI 1.10-2.16; p = 0.011). In this study, MAFLD group had more cardiovascular risk factors, MAFLD was correlated with coronary atherosclerosis,and significant stenosis.Further study found independent associations between MAFLD and noncalcified plaques and mixed plaques, which suggest a clinically relevant link between MAFLD and coronary atherosclerosis.

Abstract
BACKGROUND AND AIM Changing terminology of non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MAFLD) is recently proposed by expert panels based on metabolic dysregulations. However, clinical evidences for the risk of cardiovascular disease (CVD) in MAFLD are limited. The aim of this study is evaluating the association of cardiovascular risk in these two terminology and subgroups of MAFLD. METHODS A total of 2133 individuals who underwent ultrasound and cardiac computed tomography contemporaneously were included at a single medical checkup center. Ultrasound was used to define fatty liver, and coronary artery calcification (CAC) defined a coronary artery calcium score above 0 was used to estimate the cardiovascular risk. RESULTS Overall, 911 participants were diagnosed with fatty liver. In the unadjusted analysis, NAFLD (OR = 1.4, 95% confidence interval [CI] = 1.05-1.85, p = 0.019) and MAFLD (OR = 1.55, 95% CI = 1.29-1.86, p = 0.046) were significantly associated with CAC. However, in sex and age-adjusted analyses, only MAFLD was associated with CAC (adjusted OR [aOR] = 1.38, 95% CI = 1.14-1.69, p = 0.001). Of the three subgroups of MAFLD (diabetic, nondiabetic overweight/obese, and nondiabetic normal weight/lean with at least two metabolic abnormalities), only diabetic MAFLD was associated with CAC (aOR = 2.65, 95% CI = 1.98-3.55, p < 0.001). When the minimal number of metabolic risk abnormalities increased to three, nondiabetic normal-weight/lean MAFLD was associated with CAC (aOR = 1.35, 95% CI = 1.02-1.77, p = 0.034). CONCLUSION Diabetic MAFLD predicted high-risk CVD phenotypes the best. Metabolic risk abnormalities in nondiabetic MAFLD patients were independently associated with the risk of CVD. The proposed diagnostic criteria for nondiabetic MAFLD need further investigation in terms of CVD risk.

Abstract
OBJECTIVE The aim: To analyze the metabolic status of patients with coronary artery disease and nonalcoholic fatty liver disease depending on body mass index. PATIENTS AND METHODS Materials and methods: The cohort of patients included 107 people with coronary artery disease (CAD), nonalcoholic fatty liver disease (NAFLD) and over¬weight (n=56) or obesity (n=51). In all patients glucose, insulin, HbA1c, HOMA-IR, hsCRP, transaminases, creatinine, urea, uric acid, lipid profile, anthropometric parameters and ultrasound elastography were measured. RESULTS Results: During the analysis of serum lipid spectrum in patients with obesity: lower levels of HDL and higher TG concentration compared with patients who had overweight. The insulin level was almost twice as high as in patients with overweight and the HOMA-IR index was 3.49 (2.13;5.78), where as in patients with overweight it was 1.85 (1.28;3,01), p<0.01. In patients with coronary artery disease and overweight, the of hsCRP was 1.92 (1.18;2.98) mg/l and was significantly different from the hsCRP level in obese patients, which was 3.15 (2.64;3.66) mg/l, p=0,004. CONCLUSION Conclusions: In patients with coronary artery disease, non-alcoholic fatty liver disease and obesity, the metabolic profile was characterized by a more unfa¬vorable lipid spectrum: lower levels of HDL and higher triglicerid concentration. Carbohydrate metabolism in obese patients included disorders such us impared glucose tolerance, hyperinsulinemia and insulin resistance. There was also a correlation between body mass index with insulin and glycated hemoglobin. Higher concentration hsCRP in obese compared with patients with overweight was observed. This confirms the role of obesity in the patogenesis of coronary artery disease, non-alcoholic fatty liver disease and systemic inflammation.

Abstract
Non-alcoholic fatty liver disease (NAFLD) represents the hepatic expression of the metabolic syndrome and is the most prevalent liver disease. NAFLD is associated with liver-related and extrahepatic morbi-mortality. Among extrahepatic complications, cardiovascular disease (CVD) is the primary cause of mortality in patients with NAFLD. The most frequent clinical expression of CVD is the coronary artery disease (CAD). Epidemiological data support a link between CAD and NAFLD, underlain by pathogenic factors, such as the exacerbation of insulin resistance, genetic phenotype, oxidative stress, atherogenic dyslipidemia, pro-inflammatory mediators, and gut microbiota. A thorough assessment of cardiovascular risk and identification of all forms of CVD, especially CAD, are needed in all patients with NAFLD regardless of their metabolic status. Therefore, this narrative review aims to examine the available data on CAD seen in patients with NAFLD, to outline the main directions undertaken by the CVD risk assessment and the multiple putative underlying mechanisms implicated in the relationship between CAD and NAFLD, and to raise awareness about this underestimated association between two major, frequent and severe diseases.

Fatty Liver as Potential Biomarker of Atherosclerotic Damage in Familial Combined Hyperlipidemia. Biomedicines 2022; 10:biomedicines10081770.

Abstract
Familial combined hyperlipidemia (FCH) is a very common inherited lipid disorder, characterized by a high risk of developing cardiovascular (CV) disease and metabolic complications, including insulin resistance (IR) and type 2 diabetes mellitus (T2DM). The prevalence of non-alcoholic fatty liver disease (NAFLD) is increased in FCH patients, especially in those with IR or T2DM. However, it is unknown how precociously metabolic and cardiovascular complications appear in FCH patients. We aimed to evaluate the prevalence of NAFLD and to assess CV risk in newly diagnosed insulin-sensitive FCH patients. From a database including 16,504 patients, 110 insulin-sensitive FCH patients were selected by general practitioners and referred to the Lipid Center. Lipid profile, fasting plasma glucose and insulin were determined by standard methods. Based on the results of the hospital screening, 96 patients were finally included (mean age 52.2 ± 9.8 years; 44 males, 52 females). All participants underwent carotid ultrasound to assess carotid intima media thickness (cIMT), presence or absence of plaque, and pulse wave velocity (PWV). Liver steatosis was assessed by both hepatic steatosis index (HSI) and abdomen ultrasound (US). Liver fibrosis was non-invasively assessed by transient elastography (TE) and by fibrosis 4 score (FIB-4) index. Carotid plaque was found in 44 out of 96 (45.8%) patients, liver steatosis was found in 68 out of 96 (70.8%) and in 41 out of 96 (42.7%) patients by US examination and HSI, respectively. Overall, 72 subjects (75%) were diagnosed with steatosis by either ultrasound or HSI, while 24 (25%) had steatosis excluded (steatosis excluded by both US and HSI). Patients with liver steatosis had a significantly higher body mass index (BMI) compared to those without (p < 0.05). Steatosis correlated with fasting insulin (p < 0.05), liver stiffness (p < 0.05), BMI (p < 0.001), and inversely with high-density lipoprotein cholesterol (p < 0.05). Fibrosis assessed by TE was significantly associated with BMI (p < 0.001) and cIMT (p < 0.05); fibrosis assessed by FIB-4 was significantly associated with sex (p < 0.05), cIMT (p < 0.05), and atherosclerotic plaque (p < 0.05). The presence of any grade of liver fibrosis was significantly associated with atherosclerotic plaque in the multivariable model, independent of alcohol habit, sex, HSI score, and liver stiffness by TE (OR 6.863, p < 0.001). In our cohort of newly diagnosed, untreated, insulin-sensitive FCH patients we found a high prevalence of liver steatosis. Indeed, the risk of atherosclerotic plaque was significantly increased in patients with liver fibrosis, suggesting a possible connection between liver disease and CV damage in dyslipidemic patients beyond the insulin resistance hypothesis.

Abstract
OBJECTIVES The presence of non-alcoholic fatty liver disease (NAFLD) has been associated with major adverse cardiovascular events (MACEs); however, the mechanisms that initiate the risk for MACEs in patients with NAFLD remain unknown. We sought to investigate whether plaque progression (PP), determined by coronary CT angiography (CCTA), moderate the relationship between NAFLD and MACEs. METHODS A total of 1683 asymptomatic participants (mean age, 63.3 ± 9.4 [range, 38-85] years; 1117 men) who underwent baseline and follow-up CCTA examination were prospectively included in our study. All of the participants were divided into the NAFLD and non-NAFLD groups. PP was determined by follow-up CCTA. The primary endpoint was MACEs, defined as the composite of all-cause death, nonfatal myocardial infarction, and unplanned hospitalization for acute coronary syndrome leading to revascularization. RESULTS At follow-up CCTA, participants with NAFLD showed higher incidence of PP than those without [33.0% (248/752) vs. 16.6% (155/931), p < 0.001]. Compared with non-NAFLD participants, participants with NAFLD had a lower 9.7-year event-free survival rate (80.9 vs. 66.4%, log-rank p < 0.001). Cox regression analysis revealed NAFLD was significantly associated with MACEs (HR = 1.63, 95% CI: 1.28 to 2.06, p < 0.001) after adjusting for covariables. However, this association was no longer significant after adjustment for PP (HR = 1.10, 95% CI: 0.84 to 1.45, p = 0.496). The mediation analysis revealed that PP had a significant indirect effect (β = 0.0587, 95% CI: 0.0424 to 0.08, p < 0.001) and mediated 99.8% (p = 0.002) for the relationship between NAFLD and MACEs. CONCLUSIONS Plaque progression, identified by follow-up CCTA, mediates the relationship between NAFLD and MACEs. KEY POINTS The incidence of CCTA-identified PP was higher for participants with NAFLD than those without NAFLD (248/752 [33.0%] vs. 155/931 [16.6%], p < 0.001). Participants with NAFLD had a lower 9.7-year event-free survival rate than those without NAFLD (66.4% vs. 80.9%, log-rank p < 0.001). The mediation analysis revealed that PP had a significant indirect effect (β = 0.0587, 95% CI: 0.0424 to 0.08, p < 0.001) and mediated 99.8% (p = 0.002) for the relationship between NAFLD and MACEs.

[PMID: 35352460 PMCID: PMC9718363 DOI: 10.1111/hepr.13764] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 03/11/2022] [Accepted: 03/28/2022] [Indexed: 01/26/2023]
Abstract
Liver fibrosis is the most important prognostic factor in patients with nonalcoholic fatty liver disease (NAFLD). Several noninvasive markers for fibrosis, including blood-based markers and imaging based-markers have been developed. Indirect fibrosis markers (e.g., fibrosis-4 index and NAFLD fibrosis score) consist of standard laboratory data and clinical parameters. Given its availability and high negative predictive value for advanced fibrosis, these markers are suitable for screening at primary care. Blood-based fibrogenesis markers (enhanced liver fibrosis and N-terminal propeptide of type 3 collagen), ultrasound-based modalities (vibration-controlled transient elastography, point shear wave elastography [SWE], and two-dimensional SWE), and magnetic resonance elastography have high diagnostic accuracy for liver fibrosis and are suitable for diagnosing liver fibrosis at secondary care centers. Sequential use of these markers can increase diagnostic accuracy and reduce health care costs. Furthermore, combining noninvasive makers may assist in identifying candidates for pharmacological trials and reducing screening failure. Emerging data suggest that these noninvasive markers are associated with liver-related events (hepatocellular carcinoma and decompensation) and mortality. Furthermore, delta change in noninvasive markers over time is also associated with time-course change in fibrosis, liver-related event risk, and mortality risk. However, the association between liver fibrosis and cardiovascular disease (CVD) risk is still controversial. CVD risk may decrease in patients with decompensated liver disease and noninvasive markers may be useful for assessing CVD risk in these patients. Therefore, noninvasive markers may be utilized as measures of fibrosis as well as real-time prognostic tools, in place of liver biopsy.

Abstract
Coronary artery disease (CAD) is among the leading causes of death globally. The American Heart Association recommends that people should consume more PUFA-rich plant foods to replace SFA-rich ones to lower serum cholesterol and prevent CAD. However, PUFA may be susceptible to oxidation and generate oxidized products such as oxylipins. In this study, we investigated whether the blood oxylipin profile is associated with the risk of developing CAD and whether including identified oxylipins may improve the predictability of CAD risk. We designed a nested case-control study with 77 cases and 148 matched controls from a 10-year follow-up of the Nutrition and Health Survey in a Taiwanese cohort of 720 people aged 50 to 70. A panel of 46 oxylipins was measured for baseline serum samples. We discovered four oxylipins associated with CAD risk. 13-oxo-ODE, which has been previously found in formed plagues, was positively associated with CAD (OR = 5.02, 95%CI = 0.85 to 15.6). PGE2/PGD2, previously shown to increase cardiac output, was inversely associated (OR = 0.16, 95%CI = 0.06 to 0.42). 15-deoxy-PGJ2, with anti-inflammatory and anti-apoptosis effects on cardiomyocytes (OR = 0.26, 95%CI = 0.09 to 0.76), and 5-HETE, which was associated with inflammation (OR = 0.28, 95%CI = 0.10 to 0.78), were also negatively associated as protective factors. Adding these four oxylipins to the traditional risk prediction model significantly improved CAD prediction.

Abstract
BACKGROUND Magnetic resonance elastography (MRE) has the highest diagnostic accuracy for liver fibrosis; however, the association between MRE-associated liver stiffness and the development of hepatic and extrahepatic complications as well as mortality remains unclear. AIM In this study, we investigated the longitudinal association between MRE-associated liver stiffness and complications and mortality. METHODS This retrospective study included 2373 consecutive patients with chronic liver disease. All patients received standard of care and the development of complications was assessed every 1-6 months. RESULTS Newly diagnosed hepatocellular carcinoma (HCC), decompensation, major adverse cardiovascular events (MACE), extrahepatic cancer and death were observed in 99, 117, 73, 77 and 170 patients respectively. In multivariable analysis, the adjusted hazard ratios (aHR) (95% confidence interval [CI]) for HCC, decompensation, MACE, extrahepatic cancer and mortality were 1.28 (1.2-1.4), 1.34 (1.3-1.4), 0.96 (0.9-1.1), 1.00 (0.9-1.1) and 1.17 (1.1-1.2), respectively, with each 1-kPa increase in liver stiffness. Similarly, the aHR (95% CI) for HCC, decompensation, MACE, extrahepatic cancer and mortality were 4.20 (2.2-8.2), 67.5 (9.2-492), 0.83 (0.4-1.7), 0.90 (0.5-1.7) and 2.90 (1.6-5.4), respectively, in patients with cirrhosis (>4.7 kPa) compared to those with minimal fibrosis (<3 kPa). CONCLUSIONS Increased MRE-associated liver stiffness was associated with increased risk for HCC, decompensation and mortality in a dose-dependent fashion but not with MACE or extrahepatic cancer, implicating a significant role for MRE in liver-related events and mortality; however, further studies are warranted to explore its role in MACE and extrahepatic cancer.

Abstract
Excessive alcohol intake is an established risk factor for chronic liver disease. At the same time, moderate alcohol intake appears to reduce cardiovascular morbidity. Accordingly, recommendations for alcohol intake in patients with nonalcoholic fatty liver disease (NAFLD), who are at increased risk for liver-related and cardiovascular events, are a point of debate. Some studies have shown beneficial effects of alcohol on cardiovascular and overall mortality in this specific subset of patients. Nonetheless, even light alcohol intake appears to aggravate liver disease and increase the risk of hepatocellular cancer. Therefore, patients with nonalcoholic steatohepatitis or advanced fibrosis should be advised against consuming alcohol. On the other hand, only light alcohol consumption (<10 g/day) might be permitted in patients without significant hepatic fibrosis, provided that they are carefully followed-up. As the research field focusing on NAFLD keeps widening, more prospective studies regarding this specific subject are expected, and may provide a basis for less ambiguous recommendations.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is associated with high risk of cardiovascular disease. The prevalence is increasing to 45-65% in the general population with routine health check-up, and most subjects have the mild degree NAFLD in recent years. Moreover, there are no studies on the association between NAFLD severity and coronary atherosclerosis in the real-world setting by ultrasonography. METHODS The aim of this study was to determine the relationship between the severity of NAFLD and subclinical coronary atherosclerosis. Overall, 817 subjects meet criteria for NAFLD were enrolled in the retrospective cohort study (155 subjects were excluded). The severity of NAFLD was divided into the normal, mild, moderate and severe degree based on the finding of abdominal ultrasonography. The assessment of coronary atherosclerosis was based on CAC scan/coronary CT angiography finding in terms of CAC score ≧ 100, CAC score ≧ 400, CAD-RADS ≧ 3 and presence of vulnerable plaque(s). RESULTS A significant linear trend was observed between the severity of NAFLD and subclinical coronary atherosclerosis. Compared with the reference group (including normal, mild, and moderate NAFLD), severe degree NAFLD was the independently associated risk of subclinical coronary atherosclerosis in term of CAC score ≧ 100, CAC score ≧ 400, CAD-RADS ≧ 3 and presence of vulnerable plaque(s) based on binary logistic regression after adjustment for FRS score and body fat percentage. CONCLUSIONS Severe degree, but not mild to moderate, was associated with high risk of subclinical coronary atherosclerosis, independently of FRS score and body-fat percentage.

Liver stiffness by magnetic resonance elastography is associated with increased risk of cardiovascular disease in patients with non-alcoholic fatty liver disease. Aliment Pharmacol Ther 2021; 53:1030-1037.

Abstract
BACKGROUND Magnetic resonance elastography (MRE) is a reliable non-invasive alternative to liver biopsy for assessing liver fibrosis. There are limited data regarding an association between liver fibrosis by MRE and risk of cardiovascular disease (CVD). AIM To investigate the association of high-risk CVD phenotype determined by coronary artery calcification (CAC) with liver fibrosis by MRE in patients with non-alcoholic fatty liver disease (NAFLD). METHOD This was a cross-sectional analysis of well-characterised, prospective cohorts including 105 patients with NAFLD (MR imaging-derived proton density fat fraction ≥ 5%) with contemporaneous cardiac computed tomography (CT) and MRE. Patients were assessed using MRE for liver stiffness, and cardiac CT for the presence of CAC (defined as coronary artery calcium score > 0). Odds of presence of CAC were analysed using logistic regression analysis. RESULTS The average age and body mass index were 54.9 years and 32.9 kg/m2 respectively. In this cohort, 49.5% of patients had CAC and 35.2% had significant liver fibrosis (defined as MRE ≥2.97 kPa). Compared to patients without CAC, those with CAC were older (50.0 [39.0-59.0] vs 63.0 [55.5-67.5], P < 0.001) and had higher Framingham risk score (FRS, 1.0 [0.5-3.5] vs 6.0 [2.0-12.0], P < 0.001). In multivariable-adjusted analysis, liver stiffness as a continuous trait on MRE was independently associated with the presence of CAC in a sex and age-adjusted model (adjusted odd ratios [aOR] = 2.23, 95% confidence interval [CI] = 1.31-4.34, P = 0.007) as well as in a FRS-adjusted model (aOR = 2.16, 95% CI = 1.29-4.09, P = 0.008). When analysed as a dichotomous trait, significant fibrosis (MRE-stiffness ≥2.97 kPa) remained independently associated with the presence of CAC in both FRS-adjusted model and sex and age-adjusted model (aOR = 3.21-3.53, P = 0.013-0.017). In addition, CAC was more prevalent in patients with significant fibrosis than those without as determined by MRE (67.6% vs 39.7%, P = 0.012). CONCLUSION Liver stiffness determined by MRE is an independent predictor for the presence of CAC in patients with NAFLD. Patients with NAFLD and significant fibrosis by MRE should be considered for further cardiovascular risk assessment, regardless of their FRS.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease and considered a liver manifestation of metabolic syndrome. It is in close relationship with insulin resistance, obesity, diabetes mellitus, all of which increase risk of cardiovascular disease (CVD). Besides, many studies point out that NAFLD independently contributes to the development of atherosclerosis and CHD. On the other hand, CVDs are the leading cause of death in NAFLD patients. Many pathophysiological changes and molecular mechanisms play an important role in NAFLD for CVD formation. Atherosclerosis is common in NAFLD, which also mainly contributes to the CVD formation and CHD. Many studies linking atherosclerotic CHD and NAFLD are present in the literature. Subclinical CHD, mainly detected by coronary computed tomography views, have been detected more common in NAFLD patients. Presence of NAFLD has been found to be more common in patients with severe CHD and in stable CHD, NAFLD has been found to be associated with more diffuse disease. In acute coronary syndromes, especially in acute myocardial infarction, patients with NAFLD have been found to have poor prognosis when compared with NAFLD free patients. In this review, our aim is to evaluate the relationship between NAFLD and CHD in detail and go over the pathophysiological mechanisms underlying this relationship.

Abstract
Non-alcoholic fatty liver disease (NAFLD) and cardiovascular diseases (CVD) share similar risk factors. Recent studies have focused on obesity and insulin resistance, but the link between NAFLD and CVD persists regardless of traditional risk factors. Despite the increased incidence and prevalence of NAFLD worldwide, there has been no thorough investigation of gender disparities nor a closer look taken into investigating the role gender may play in increased cardiovascular (CV) mortality in people with NAFLD. We assessed the incidence and prevalence of CV events and mortality based on gender in people with NAFLD, at any stage of fibrosis. A meta-regression was conducted to further analyze the impact of age on both genders. An aggregate analysis was performed on ten studies with NAFLD people. A random-effects model was used to pool the overall incidence and prevalence rates of CV events and mortality as well as all-cause mortality to examine any gender disparity. We also performed a meta-regression analysis to evaluate the effect of age on mortality for men versus women with NAFLD and CV events and mortality. Summary odds ratios (OR) and 95% confidence intervals (CI) were estimated using a random-effects model. In 108,711 people with NAFLD, of which 44% were females and 56% were males, all-cause mortality was 1.5x higher in women compared to men (OR 1.65, 95% CI 1.12-2.43, P<0.012). CV events and mortality were also 2x higher in women compared to men (OR 2.12 95% CI 1.65-2.73, P<0.001)). On meta-regression, females had higher mortality with advancing age starting at age 42 (coefficient =0.0518, P=0.00001). For people with NAFLD, women had a markedly higher incidence and prevalence of CV events, CV mortality, and all-cause mortality when compared to men. As the incidence and prevalence of NAFLD and concomitant CV events increase worldwide, we urge the medical community to increase surveillance and perform rigorous cardiovascular risk assessments for women, especially beginning at age 42. Additionally, we recommend heterogeneous surveys of gender disparities, increased focus on gender as a decisive factor for downstream CV events, the relationship between NAFLD severity and gender-based mortality differences, and larger studies representing equivalent male and female populations.
