Angiotensin receptor neprilysin inhibitor for patients with heart failure and reduced ejection fraction: Real-world experience from Turkey (ARNi-TR).

OBJECTIVE: Heart failure (HF) is a growing public health problem with high morbidity and mortality. Recently, angiotensin receptor neprilysin inhibitor (ARNi) has emerged as a promising treatment for HF with reduced ejection fraction (HFrEF). Here, we shared our experience with the use of ARNi in HFrEF from multiple centers in Turkey. METHODS: The ARNi-TR is a multicenter, noninterventional, retrospective, observational study. Overall, 779 patients with HF from 22 centers in Turkey who were prescribed sacubitril/valsartan were examined. Initial clinical status, biochemical and echocardiographic parameters, and New York Heart Association functional class (NYHA-FC) values were compared with follow-up values after 1 year of ARNi use. In addition, the effect of ARNi on number of annual hospitalizations was investigated, and the patients were divided into 2 groups, depending on whether ARNi was initiated at hospitalization or under outpatient clinic control. RESULTS: N-terminal pro-brain natriuretic peptide (NT-proBNP), left-ventricle ejection fraction (LV-EF), and NYHA-FC values improved significantly in both groups (all parameters, p<0.001) within 1-year follow-up. In both groups, a decrease in hemoglobin A1c (HbA1c) values was observed in ARNi use (p<0.001), and a decrease in daily diuretic doses and hospitalizations owing to HF were observed after ARNi use (all comparisons, p<0.001). Hypotension (16.9%) was the most common side effect in patients using ARN. CONCLUSION: The ARNi-TR study offers comprehensive real-life data for patients using ARNi in Turkey. The use of ARNi has shown significant improvements in FC, NT-proBNP, HbA1c levels, and LV-EF. Likewise, reductions in the number of annual hospitalizations and daily furosemide doses for HF were seen in this study.

The role of serum interleukin-37 levels, inflammation and blood pressure in patients with preeclampsia.

AIM: Preeclampsia is one of the major causes of perinatal, fetal, and maternal mortality and morbidity. The aim of this study was to investigate the association of serum interleukin 37 (IL 37) with preeclampsia. METHODS: 39 women with preeclampsia were included as the study group. 38 healthy, and normotensive pregnant women, at similar gestational week with similar gravidity volunteered as the control group. Clinical findings, biochemical parameters, maternal and perinatal outcomes, and the serum concentrations of IL37 were compared between the groups. The relationship of IL 37 concentrations with clinical findings and blood pressure outcomes were also investigated. RESULTS: Maternal serum IL 37 concentrations were significantly higher in patients with preeclampsia compared to the healthy pregnant women in the control group (p = .005). IL 37 positively correlated systolic blood pressure (BP) (r = 0.344, p = .002), and diastolic BP (r = 0.332, p = .003). IL 37 was identified as an independent predictor of preeclampsia. CONCLUSIONS: Serum IL 37 concentrations were higher in preeclamptic patients compared to healthy pregnant women. Furthermore, IL 37 concentrations achieved success in identifying preeclampsia with hypertension. Increased IL 37 activity may have a role in the pathophysiology of preeclampsia.

An echocardiographic predictor of contrast-induced nephropathy following percutaneous coronary intervention in acute coronary syndrome: aortic valve sclerosis.

Objective. Aortic valve sclerosis (AVS) is closely related to endothelial dysfunction. The association of AVS with contrast-induced nephropathy (CIN) is unknown. We planned to investigate the relationship of AVS besides known parameters with CIN. Design. Baseline characteristics, biochemical values, and AVS of 292 consecutive patients with acute coronary syndrome (ACS) that underwent percutaneous coronary intervention (PCI) were analyzed. Results. Fifty-three patients (18.2%) had CIN. Patients with CIN were older, less likely to be smokers, and had more prevalent prior bypass surgery, higher Mehran score, creatinine, and uric acid concentrations than those without CIN. AVS was more prevalent in patients with CIN. Logistic regression analysis including all related parameters identified Mehran score (OR = 1.036, p = .033), uric acid concentration (OR = 1.244, p = .023), and AVS (OR: 2.223, p = .027) as independent predictors of CIN. Conclusion. AVS is independently associated with CIN in patients with acute coronary syndrome undergoing percutaneous coronary intervention. AVS may help to identify high-risk patients for CIN, who would benefit from preventive measures.

The relationship between total atrial conduction time and left atrial global strain in patients with psoriasis vulgaris.

INTRODUCTION: Psoriasis vulgaris is a chronic, multisystem disease that results in the development of atrial fibrillation (AF) over time. In this study, our goal was to assess predictors of AF in patients with psoriasis, including total atrial conduction time (TACT) and left atrial global longitudinal strain (LAGLS). MATERIAL AND METHODS: A total of 80 individuals, including 40 psoriasis patients and 40 healthy controls, were enrolled in the study. A physical examination was performed, biochemical parameters were studied, and Holter electrocardiography was carried out. Conventional echocardiography, atrial tissue Doppler, and speckle tracking echocardiography were recorded. RESULTS: No significant difference was observed between psoriasis patients and healthy controls with regard to age, and the average duration of psoriasis was 5.7 years. High-sensitivity C reactive protein levels were higher in the patient group compared to the control group (respectively, group 1: 1 ±0.8; group 2: 0.6 ±0.3, p < 0.05). Atrial arrhythmia was not detected in the Holter ECG monitoring. A significant moderate negative correlation between TACT and LAGLS (r = -0.57, p < 0.05) was observed, and there was a significant moderate positive correlation between the duration of disease and TACT (r = 0.52, p < 0.05). CONCLUSIONS: In the current study, we determined that LAGLS decreased, TACT was prolonged, and P-wave dispersion increased in patients with psoriasis. The current results may improve predictions of AF risk in psoriasis patients in clinical practice.

Hair whitening and obesity are independently related to ascending aorta dilatation in young-middle aged men.

OBJECTIVE: Hair whitening (HW) is strongly linked with aging. Ascending aortic dilation (AAD) and HW share common etiologic factors. We investigated the association of HW with ascending aortic diameters. METHODS: Our study included 93 male subjects aged below 50 years. All patients underwent echocardiography to measure ascending aortic diameter, in addition to routine biochemistry tests, physical examination, and thorough medical history. HW score (HWS) was defined according to the percentage of white hair (HWS 1: <25%; HWS 2: 25-50%; HWS 3: 50-75%; and HWS 4: 75-100). RESULTS: Patients with highest HWS were older and had a higher percentage of hypertension (HT) and family history of HW. Moreover, this subgroup had increased ascending aortic diameter, higher serum uric acid, and lower total bilirubin concentrations. Multivariate analyses including age, HT, height, waist circumference, c-reactive protein, and family history of HW identified body weight and HWS as the independent predictors of ascending aortic diameter. CONCLUSION: An independent association between the degree of HW and AAD exists in middle-aged men, which may depend on coexisting factors that enhance both pathologies rather than causality. We think that oxidative stress may be one of these stressors.

The role of serum bilirubin levels in determining venous thromboembolism.

OBJECTIVE: Venous thromboembolism (VTE) is a disease that includes both deep venous thrombosis (DVT) and pulmonary embolism (PE). Bilirubin is an endogenous anti-inflammatory marker associated with atherothrombosis. The purpose of our study was to investigate the association of serum bilirubin levels with the presence of VTE. METHODS: A total of 103 patients with VTE (distal DVT, n = 34; proximal DVT, n = 30; PE, n = 39) and 50 control patients were cross-sectionally enrolled. Peripheral venous duplex ultrasound and computed tomography were used for the diagnosis of VTE. Fasting blood samples were drawn for biochemical analyses. RESULTS: Baseline characteristics were not different between groups. The VTE group had lower bilirubin level (9.0 ± 2.6 µmol/L vs 7.3 ± 3 µmol/L; P = .001) and higher high-sensitivity C-reactive protein (hs-CRP) concentration (0.8 [0.3-2] mg/L vs 1.1 [0.2-3] mg/L; P = .008) and white blood cell count (7.4 ± 1.5 × 109/L vs 8.2 ± 2.7 × 109/L; P = .02) compared with control patients. In the analysis of variance, the levels of total direct bilirubin and hs-CRP were clearly different between the control group and VTE subgroups (distal and proximal DVT and PE). The receiver operating characteristic curve analysis showed a cutoff value of 8.9 µmol/L for total bilirubin (sensitivity, 74%; specificity, 55%) and an area under the curve of 0.659 (P < .001). CONCLUSIONS: Bilirubin level, hs-CRP concentration, and white blood cell count were independently associated with VTE.

Epicardial Adipose Tissue Predicts Carotid Intima-Media Thickness Independently of Body Mass Index and Waist Circumference.

Background: Visceral obesity is strongly associated with atherosclerosis. Even though waist circumference (WC) is the most common assessment method of total visceral adipose tissue and cardiometabolic risk, this method lacks direct measurement of adipose tissue and has better correlation to subcutaneous fat rather than visceral fat. We intended to investigate whether epicardial adipose tissue (EAT) is clinically superior to body mass index (BMI) and WC in predicting Framingham risk score (FRS) and carotid intima-media thickness (CIMT). Methods: Our study included 331 patients who were admitted to our outpatient clinic for risk factor assessment. We calculated BMI, FRS, and WC, and the patients underwent echocardiographic and carotid examinations to measure EAT and CIMT. The metabolic syndrome (MS) score was calculated by summing the MS risk factor scores. Results: The area under the curve values of EAT were similar to FRS and higher than those of weight, BMI, and WC for both increased CIMT and the presence of carotid plaque. Male gender, age, low-density lipoprotein-cholesterol level, and EAT thickness were independent predictors of CIMT, whereas male gender, age, WC, uric acid concentration, and EAT significantly predicted the presence of carotid plaque. Conclusions: This study demonstrated that epicardial adipose tissue (EAT) has a stronger correlation with CIMT than BMI and WC, and it was a significant predictor of increased CIMT and the presence of carotid plaque. Additional data are required to clarify the diagnostic and therapeutic role of EAT in managing obese patients, and to decrease their cardiometabolic risk.

The effect of epicardial adipose tissue thickness with irritable bowel syndrome.

OBJECTIVE: To investigate the association of epicardial adipose tissue thickness with irritable bowel syndrome. METHODS: This case-control and observational study was conducted in Recep Tayyip Erdogan University between January and December 2014, and comprised patients of irritable bowel syndrome and healthy controls who underwent a complete transthoracic echocardiographic examination as well as measurements of epicardial adipose tissue. They were screened for psychiatric or organic bowel diseases for the sake of precise diagnosis. Epicardial fat thickness was measured perpendicularly in front of the right ventricular free wall at end-diastole.SPSS 15 was used to analyse the data. RESULTS: Of the 75 subjects, 44(59%) were patients and 31(41%) were controls. There was no statistically significant difference between the groups except epicardial adipose tissue thickness, which was significantly elevated in patients (p<0.001). C-reactive protein was significantly higher in patients (p=0.002). Epicardial adipose tissue (p<0.001) and haematocrit (p<0.05) were independent predictors of irritable bowel syndrome. CONCLUSIONS: Increased epicardial adipose tissue thickness, and accompanying low-grade inflammation appeared to be involved in irritable bowel syndrome pathogenesis.

The Relationship between Serum Apelin Levels and the Severity of Calcific Aortic Stenosis.

Background: Apelin, an endogenous peptide, has recently gained attention due to its positive inotropic effects in heart failure physiopathology. We investigated the relationship between serum apelin levels and the severity of calcific aortic stenosis (AS). Methods: A total of 68 consecutive patients diagnosed with calcific AS and a control group of 32 subjects were included in the study. The subjects were divided into three group as follows: the control group, the mild-moderate AS group and the severe AS group. Blood samples were obtained from all of the subjects, which were used for biochemical comparisons of apelin 36 and high-sensitive C-reactive protein (hsCRP) levels. Results: Plasma apelin 36 levels were significantly lower in the patients with severe AS [490 (247-1074) pg/ml] compared to both the mild-moderate AS [209 (97-453) pg/ml] and control [660 (378-1200) pg/ml] groups (p < 0.001). Correlation analysis between the left ventricular mass index and apelin concentrations revealed a significant negative correlation between the two parameters (p < 0.001, r = -0.478). Conclusions: Our study demonstrated decreased apelin levels and increased hsCRP concentrations in patients with severe calcific AS. Our findings may help to clarify the exact pathophysiologic role of apelin in cardiovascular diseases.

Prolonged QRS duration on surface electrocardiogram is associated with left ventricular restrictive filling pattern.

BACKGROUND: Prolonged QRS duration is associated with decreased left ventricular (LV) systolic function. However, the relation between LV restrictive filling pattern (RFP) and QRS duration has not been investigated yet. The purpose of our study was to assess this relationship. METHODS: We analyzed standard 12-lead surface electrocardiogram (ECG) of 155 consecutive patients. Mitral inflow and septal tissue velocities were obtained using the apical 4-chamber view with pulsed Doppler echocardiography. Patients were divided into 2 groups according to measured deceleration time (DT): restrictive (with DT ≤130 ms) or non-restrictive (with DT >130 ms). RESULTS: QRS duration was significantly longer in the restrictive group than in the non-restrictive group (0.101 vs. 0.090 s, p < 0.0001). QRS duration of >0.10 s was highly specific (82.6%), but modestly sensitive (64.7%), for the prediction of LV RFP. Multivariate analyses demonstrated that E/A ratio, peak E, peak A, septal e', and a' velocities were significantly associated with RFP. CONCLUSIONS: Prolonged QRS duration (>0.10 s) obtained from a standard resting 12-lead ECG is associated with LV RFP. However, the relationship of QRS duration with RFP was not independent of echocardiographic parameters.

An increase in epicardial adipose tissue is strongly associated with carotid-intima media thickness and atherosclerotic plaque, but LDL only with the plaque.

OBJECTIVE: Carotid intima-media thickness (CIMT) is reliable marker of subclinical atherosclerosis and cardiovascular events. Until today, there was no study that investigated whether epicardial adipose tissue (EAT), which is a surrogate for lipid depot in a special visceral tissue or circulating lipids, is more important for CIMT and atherosclerotic plaque. METHODS: Our study, having cross-sectional and prospective observational design, included 252 patients who were admitted to our outpatient clinic. EAT identified as an echo-free space under the pericardial layer on 2-dimensional echocardiography, was measured perpendicularly in front of the right ventricular free wall at end-systole. RESULTS: EAT significantly correlated with CIMT (r=0.623, p<0.001). CIMT was significantly increased with rising EAT thickness (0.72±0.15 mm, 0.85±0.16 mm, and 0.95±0.12 mm in patients with EAT <5 mm, 5-7, and >7 mm, p<0.001, respectively). Multiple linear regression analysis revealed that age (Beta: 0.406, p<0.001), male gender (Beta: 0.244, p<0.001), and EAT (Beta: 0.450, p<0.001) as independent correlates of CIMT. Otherwise, in logistic regression analysis, only EAT (OR, 1.386; 95% CI, 1.203-1.597, p<0.001) and LDL cholesterol (OR, 1.013; 95% CI, 1.002-1.013, p=0.02) were independent predictors for presence of carotid plaque. CONCLUSION: Our study showed that EAT has a relationship with both CIMT and the presence of carotid plaque, but LDL is independently related to the plaque. This finding suggests that EAT thickness may be a risk factor and biomarker, playing an important role beginning from early stages of atherosclerosis, unlike LDL cholesterol, which appear to have a role in later stages of atherosclerosis.

Total Bilirubin Levels Predict Subclinical Atherosclerosis in Patients With Prediabetes.

Bilirubin may have important antiatherosclerotic effects. Prediabetes (PD), the intermediate stage before diabetes mellitus, is associated with increased cardiovascular morbidity and mortality. We evaluated the relationship between serum bilirubin levels and carotid intima-media thickness (cIMT), as a surrogate marker of subclinical atherosclerosis, in patients with PD. We enrolled 170 consecutive patients with PD. The patients underwent ultrasonography to evaluate cIMT. The patients were divided into groups according to cIMT values (<0.9 vs ≥0.9 mm). The patients with cIMT ≥ 0.9 mm had significantly higher diastolic blood pressure, neutrophil-lymphocyte ratio (NLR), and glycated hemoglobin values compared with patients having cIMT < 0.9 mm, whereas total and direct bilirubin values were significantly lower in this group. Multivariate regression analyses revealed NLR and total bilirubin as the independent predictors of subclinical atherosclerosis. The present study demonstrated that NLR and lower total bilirubin levels were independent predictors of subclinical atherosclerosis in patients with PD. Simple measures such as NRL and total bilirubin may provide predictive information regarding the risk of cardiovascular disease in patients with PD.

The role of urotensin II and atherosclerotic risk factors in patients with slow coronary flow.

BACKGROUND: Slow coronary flow (SCF) is an angiographic finding characterized with delayed opacification of epicardial coronary arteries without obstructive coronary disease. Urotensin II (UII) is an important vascular peptide, which has an important role in hypertension, coronary artery disease, and vascular remodeling in addition to potent vasoconstrictor effect. OBJECTIVES: We investigated UII levels, hypertension, and other atherosclerotic risk factors in patients with SCF, a variety of coronary artery disease. METHODS: We enrolled 14 patients with SCF and 29 subjects with normal coronary arteries without SCF. We compared the UII levels and the atherosclerotic risk factors between patients with SCF and control subjects with normal coronary flow. RESULTS: UII concentrations were significantly higher in patients with SCF compared to controls (711.0 ± 19.4 vs. 701.5 ± 27.2 ng/mL, p = 0.006). We detected a positive correlation between SCF and age (r = 0.476, p = 0.001), BMI (r = 0.404, p = .002), UII concentrations (r = 0.422, p = 0.006), and hypertension (r = 0.594, p = 0.001). CONCLUSION: We identified increased UII levels in patients with SCF. We think that UII concentrations may be informative on SCF pathogenesis due to relationship with inflammation, atherosclerosis, and vascular remodeling.

The relationship between epicardial adipose tissue and P wave and QT dispersions.

OBJECTIVE: Epicardial adipose tissue (EAT) secretes various pro-inflammatory and atherogenic mediators that have several endocrine and paracrine effects on heart. This study investigated the influence of EAT on QT and P wave dispersions (QTd, PWd), as simple, non-invasive tools of proarrhythmia on surface ECG. METHODS: This was a cross-sectional study and included 70 patients with normal coronary arteries who underwent 12-derivation electrocardiography, echocardiography and biochemical examinations in order for QTd, PWd, and EAT thickness to be measured. RESULTS: Median EAT thickness was 4.1 mm. Correlation analyses revealed that EAT was significantly associated with age (r=0.412, p<0.001), weight (r=0.262, p=0.028), body mass index (r=0.396, p<0.001), left atrium diameter (r=0.518, p<0.001), fasting plasma glucose (r=0.245, p=0.041), maximum P wave duration (r=0.343, p=0.004), minimum P wave duration (r=0.275, p=0.021) and PWd (r=0.265, p=0.026). No relation was found between study parameters and QTd. However, P wave dispersion was significantly related to EAT thickness (r=0.265, p=0.026), left atrium diameter (r=0.483, p<0.001), and the triglyceride levels (r=0.267, p=0.028). Multiple linear regression analyses revealed left atrial diameter as the only independent predictor of PWd. CONCLUSION: A significant association between EAT and PWd was demonstrated in the study. While EAT is related to both increased PWd and left atrial size, left atrial diameter seems to be more important than EAT for prediction of atrial fibrillation (AF) in patients with normal coronary arteries.

Relation of Angiographic Thrombus Burden with Severity of Coronary Artery Disease in Patients with ST Segment Elevation Myocardial Infarction.

BACKGROUND We planned to investigate the relationship of thrombus burden with SYNTAX score in patients with ST elevation myocardial infarction (STEMI). MATERIAL AND METHODS We retrospectively enrolled 780 patients who underwent PPCI in our clinic due to STEMI. Clinical, laboratory, and demographic properties of the patients were recorded. Angiographic coronary thrombus burden was classified using thrombolysis in myocardial infarction (TIMI) thrombus grades. RESULTS Patients with high thrombus burden were older, with higher diabetes prevalence longer pain to balloon time, higher leukocyte count, higher admission troponin, and admission CK-MB concentrations. SYNTAX score was higher and myocardial perfusion grades were lower in patients with high thrombus burden. Multivariate logistic regression analysis revealed SYNTAX score as the strongest predictor of thrombus burden. ROC analysis demonstrated a sensitivity of 75.5%, specificity of 61.2%, and cut-off value of >14 (area under the curve (AUC): 0.702; 95% confidence interval [CI]: 0.773-0.874;P<0.001) for high thrombus burden. CONCLUSIONS SYNTAX score may have additional value in predicting higher thrombus burden besides being a marker of coronary artery disease severity and complexity.

Multiple simultaneous venous and arterial thromboses in a patient with factor V Leiden disorder: Detection by multislice computed tomography.

Arterial thrombosis is extremely rare in patients with factor V Leiden (FVL) mutation. Recent advances in multislice computed tomography (MSCT) technology facilitated diagnosis of thromboembolic events accurately without delay. We report a patient with FVL mutation and acute bilateral lower extremity deep venous thromboses, pulmonary thromboembolism, and acute left anterior descending artery thrombosis, all diagnosed by MSCT. MSCT has been utilized for prompt diagnosis of the concomitant thrombotic pathologies simultaneously.

The relationship of plasma catestatin concentrations with metabolic and vascular parameters in untreated hypertensive patients: Influence on high-density lipoprotein cholesterol.

OBJECTIVE: Catestatin has several cardiovascular actions, in addition to diminished sympatho-adrenal flow. Decreased plasma catestatin levels may reflect a predisposition for the development of hypertension and metabolic disorders. We planned to investigate the possible roles of catestatin in untreated hypertensive patients. As a secondary objective, we compared catestatin concentrations of healthy subjects with those of hypertensive patients in order to understand whether catestatin is increased reactively or diminished at onset. METHODS: Our study was cross-sectional and observational. The patient group, comprising 109 consecutive untreated hypertensive patients without additional systemic or coronary heart disease, underwent evaluations of plasma catestatin, waist circumference, lipid parameters, left ventricular mass, carotid intima-media thickness, and flow-mediated dilation of the brachial artery. Additionally, we measured catestatin concentrations of 38 apparently healthy subjects without any disease using a commercial enzyme-linked immunosorbent assay kit. RESULTS: We documented increased catestatin concentrations in previously untreated hypertensive patients compared to healthy controls (2.27±0.83 vs. 1.92±0.49 ng/mL, p=0.004). However, this association became insignificant after adjustments for age, gender, height, and weight. Within the patient group, catestatin levels were significantly higher in females. Among all study parameters, age, high-density lipoprotein cholesterol (HDL-C) correlated positively to plasma catestatin, whereas triglycerides, hemoglobin, and left ventricular mass correlated negatively to plasma catestatin. We could not detect an association between vascular parameters and catestatin. Catestatin levels were significantly elevated with increasing HDL-C (1.91±0.37, 2.26±0.79, and 3.1±1.23 ng/mL in patients with HDL-C <40, 40-60, and >60 mg/dL, respectively). Multiple linear regression analysis revealed age (beta: 0.201, p=0.041) and HDL-C (beta: 0.390, p<0.001) as independent correlates of plasma catestatin concentration. Additionally, male gender (beta:-0.330, p=0.001) and plasma catestatin (beta: 0.299, p=0.002) were significantly associated with HDL-C concentrations. CONCLUSION: We documented that plasma catestatin is an independent predictor of high-density lipoprotein cholesterol. In addition to antihypertensive effects, catestatin appears to be related to improved lipid and metabolic profiles. Coexistence of low catestatin levels with low HDL-C may provide a probable mechanism for the predictive value of low HDL-C for increased hypertension and cardiovascular events.

Bilirubin Level is Associated with Left Ventricular Hypertrophy Independent of Blood Pressure in Previously Untreated Hypertensive Patients.

BACKGROUND AND OBJECTIVES: Left ventricular hypertrophy (LVH), a sign of subclinical cardiovascular disease, is an important predictor of cardiovascular morbidity and mortality. The aim of our study was to determine the association of left ventricular mass (LVM) with possible causative anthropometric and biochemical parameters as well as carotid intima-media thickness (CIMT) and brachial flow-mediated dilation (FMD) as surrogates of atherosclerosis and endothelial dysfunction, respectively, in previously untreated hypertensive patients. SUBJECTS AND METHODS: Our study included 114 consecutive previously untreated hypertensive patients who underwent echocardiography and ultrasonography to evaluate their vascular status and function via brachial artery CIMT and FMD. RESULTS: Among all study parameters, age, systolic blood pressure (BP), diastolic BP, pulse pressure, plasma glucose, uric acid, total bilirubin, direct bilirubin, hemoglobin, and CIMT were positively correlated with the LVM index. Multiple logistic regression analysis revealed that office systolic BP, age, male gender, and total bilirubin were independent predictors of LVH. CONCLUSION: Bilirubin seems to be related to LVM and LVH. The positive association of bilirubin with these parameters is novel and requires further research.
