Abstract
INTRODUCTION Prevalence of cardiac and vascular fibrosis in patients with Idiopathic Pulmonary Fibrosis (IPF) has not been extensively evaluated. AIM In this study, we aimed to evaluate the heart and vessels functional and structural properties in patients with IPF compared to healthy controls. An exploratory analysis regarding disease severity in IPF patients has been done. METHODS We enrolled 50 patients with IPF (at disease diagnosis before antifibrotic therapy initiation) and 50 controls matched for age and gender. Heart was evaluated through echocardiography and plasmatic NT-pro-brain natriuretic peptide that, together with patients' symptoms, allow to define the presence of Heart Failure (HF) and diastolic dysfunction. Vessels were evaluated through Flow Mediated Dilation (FMD - endothelial function) and Pulse Wave Velocity (PWV-arterial stiffness) RESULTS: Patients with IPF had a prevalence of diastolic disfunction of 83.8%, HF of 37.8% and vascular fibrosis of 76.6%. No statistically significant difference was observed in comparison to the control group who showed prevalence of diastolic disfunction, HF and vascular fibrosis of 67.3%, 24.5% and 84.8%, respectively. Disease severity seems not to affect PWV, FMD, diastolic dysfunction and HF. CONCLUSIONS Patients with IPF early in the disease course do not present a significant CV fibrotic involvement when compared with age- and sex-matched controls. Bigger and adequately powered studies are needed to confirm our preliminary data and longitudinal studies are required in order to understand the time of appearance and progression rate of heart and vascular involvement in IPF subjects.

Abstract
Body surface area (BSA) is the most commonly used metric for body size indexation of echocardiographic measures, but its use in patients who are underweight or obese is questioned (body mass index (BMI) < 18.5 kg/m2 or ≥ 30 kg/m2, respectively). We aim to use survival analysis to identify an optimal body size indexation metric for echocardiographic measures that would be a better predictor of survival than BSA regardless of BMI. Adult patients with no prior valve replacement were selected from the National Echocardiography Database Australia. Survival analysis was performed for echocardiographic measures both unindexed and indexed to different body size metrics, with 5-year cardiovascular mortality as the primary endpoint. Indexation of echocardiographic measures (left ventricular end-diastolic diameter [n = 230,109] and mass [n = 224,244], left atrial volume [n = 150,540], aortic sinus diameter [n = 90,805], right atrial area [n = 59,516]) by BSA had better prognostic performance vs unindexed measures (underweight: C-statistic 0.655 vs 0.647; normal weight/overweight: average C-statistic 0.666 vs 0.625; obese: C-statistic 0.627 vs 0.613). Indexation by other body size metrics (lean body mass, height, and/or weight raised to different powers) did not improve prognostic performance versus BSA by a clinically relevant magnitude (average C-statistic increase ≤ 0.02), with smaller differences in other BMI subgroups. Indexing measures of cardiac and aortic size by BSA improves prognostic performance regardless of BMI, and no other body size metric has a clinically meaningful better performance.

Associations of Traditionally Determined Left Ventricular Mass Indices and Hemodynamic and Non-Hemodynamic Components of Cardiac Remodeling with Diastolic and Systolic Function in Patients with Chronic Kidney Disease. J Clin Med 2023; 12:4211. [PMID: 37445246 PMCID: PMC10342723 DOI: 10.3390/jcm12134211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 06/18/2023] [Accepted: 06/19/2023] [Indexed: 07/15/2023] Open
Abstract
We aimed to evaluate the extent to which different left ventricular mass parameters are associated with left ventricular function in chronic kidney disease (CKD) patients. We compared the associations between traditionally determined left ventricular mass indices (LVMIs) and hemodynamic (predicted LVMIs) and non-hemodynamic remodeling parameters with left ventricular function in patients with CKD; non-hemodynamic remodeling was represented by inappropriate left ventricular mass and inappropriate excess LVMIs (traditionally determined LVMIs-predicted LVMIs). Non-hemodynamic left ventricular remodeling parameters were strongly associated with impaired left ventricular systolic function (p < 0.001), whereas hemodynamic left ventricular remodeling was also related strongly (p < 0.001) but directly to left ventricular systolic function. Independent of one another, hemodynamic and non-hemodynamic left ventricular remodeling had associations in opposite directions to left ventricular systolic function and was associated directly with traditionally determined left ventricular mas indices (p < 0.001 for all relationships). Non-hemodynamic cardiac remodeling parameters discriminated more effectively than traditionally determined LVMIs between patients with and without reduced ejection fraction (p < 0.04 for comparison). Left ventricular mass parameters were unrelated to impaired diastolic function in patients with CKD. Traditionally determined LVMIs are less strongly associated with impaired systolic function than non-hemodynamic remodeling parameters (p < 0.04-0.01 for comparisons) because they represent both adaptive or compensatory and non-hemodynamic cardiac remodeling.

Abstract
Abstract
Arterial hypertension remains the most frequent cardiovascular (CV) risk factor, and is responsible for a huge global burden of disease. Echocardiography is the first-line imaging method for the evaluation of cardiac damage in hypertensive patients and novel techniques, such as 2D and D speckle tracking and myocardial work, provide insight in subclinical left ventricular (LV) impairment that would not be possible to detect with conventional echocardiography. The structural, functional, and mechanical cardiac remodelling that are detected with imaging are intermediate stages in the genesis of CV events, and initiation or intensification of antihypertensive therapy in response to these findings may prevent or delay progressive remodelling and CV events. However, LV remodelling—especially LV hypertrophy—is not specific to hypertensive heart disease (HHD) and there are circumstances when other causes of hypertrophy such as athlete heart, aortic stenosis, or different cardiomyopathies need exclusion. Tissue characterization obtained by LV strain, cardiac magnetic resonance, or computed tomography might significantly help in the distinction of different LV phenotypes, as well as being sensitive to subclinical disease. Selective use of multimodality imaging may therefore improve the detection of HHD and guide treatment to avoid disease progression. The current review summarizes the advanced imaging tests that provide morphological and functional data about the hypertensive cardiac injury.

Abstract
AIMS A pattern of reduced basal longitudinal strain (BLS) is often observed with left ventricular (LV) hypertrophy (LVH). Whether this pattern is associated with poor outcome is unclear. We aimed to evaluate the prognostic value of regional longitudinal strain according to LV geometry. METHODS AND RESULTS We investigated participants in the 4th Copenhagen City Heart Study who had an echocardiogram with speckle tracking performed. Participants were stratified according to the presence of LVH (LV mass index ≥116 g/m2 for men and ≥96 g/m2 for women). The outcome was major adverse cardiovascular events (MACE) defined as a composite of myocardial infarction, heart failure, and/or cardiovascular death. The study population consisted of 1090 participants. Mean LVEF was 60% and 160 (15%) had LVH. During a median follow-up of 14.7 years, there were 137 events. Both BLS and midventricular strain, but not apical strain, became incrementally impaired in the spectrum from normal to hypertensives subjects without LVH, and to participants with hypertension and LVH. After multivariable adjustment, BLS and midventricular strain were independently associated with MACE in participants with LVH (BLS: HR 1.08, 95% CI 1.00-1.17, P = 0.041; midventricular strain: HR 1.10, 95% CI 1.00-1.21, P = 0.041) but not in participants without LVH (BLS: HR 0.96, 95% CI 0.90-1.01, P = 0.13; midventricular strain: HR 0.97, 95% CI 0.91-1.03, P = 0.36). CONCLUSION BLS and midventricular strain, but not apical strain, become incrementally impaired in the spectrum from normal geometry to LVH, and are independently associated with MACE in participants with LVH.

Abstract
Introduction The augmentation index (AIx) or central systolic blood pressure (SBP), measured by radial applanation tonometry, has been reported to be independently associated with left ventricular hypertrophy (LVH) in Japanese hypertensive patients. Cuff-based oscillometric measurement of the AIx using Mobil-O-Graph® showed a low or moderate agreement with the AIx measurement with other devices. Methods The AIx measured using the Mobil-O-Graph was validated against the tonometric measurements of the radial AIx measured using HEM-9000AI in 110 normotensive healthy individuals (age, 21-76 years; 50 men). We investigated the relationship between the central hemodynamics assessed using the Mobil-O-Graph and LVH in 100 hypertensive patients (age, 54-75 years; 48 men), presenting a wall thickness of ≥11 mm and ≥10 mm in men and women, respectively. Results Although the Mobil-O-Graph-measured central AIx showed no negative values, it correlated moderately with the HEM-9000AI-measured radial AIx (r = 0.602, p < 0.001) in the normotensive individuals. The hypertensive patients did not show a significant difference in the central SBP between the sexes, but the central AIx was lower in men than in women. The independent determinants influencing left ventricle (LV) mass index (LVMI) (R2 = 0.362; adjusted R2 = 0.329, p < 0.001) were heart rate (β = -0.568 ± 0.149, p < 0.001), central SBP (β = 0.290 ± 0.100, p = 0.005), and aortic root diameter (β = 1.355 ± 0.344, p = 0.001). Age (β = -0.025 ± 0.124, p = 0.841) and the central AIx (β = 0.120 ± 0.131, p = 0.361) were not independently associated with the LVMI. The area under the receiver operator characteristic curve to evaluate the diagnostic performance of the central AIx for the presence of LVH (LVMI >118 g/m2 in men or >108 g/m2 in women) was statistically significant in men (0.875, p < 0.001) but not in women (0.622, p = 0.132). In men, a central AIx of 28.06% had a sensitivity of 83.3% and specificity of 80.0% for detecting LVH. Conclusions AIx measurement in men provided useful prognostic information for the presence of LVH. Pulse-wave analysis assessed using the Mobil-O-Graph may be a valuable tool for detecting LVH in hypertensive patients.

Abstract
OBJECTIVE In this study, we aimed to compare the functional adaptations of the left ventricle in variant forms of left ventricular hypertrophy (LVH) and to evaluate the use of two-dimensional speckle tracking echocardiography (2D-STE) in differential diagnosis and prognosis. METHODS This was a prospective cohort study of 68 patients with LVH, including 20 patients with non-obstructive hypertrophic cardiomyopathy (HCM), 23 competitive top-level athletes free of cardiovascular disease, and 25 patients with hypertensive heart disease (HHD). All the subjects underwent 2D transthoracic echocardiography (TTE) and 2D-STE. The primary endpoint was all-cause mortality. Global longitudinal strain (GLS) below -12.5% was defined as severely reduced strain, -12.5% to -17.9% as mildly reduced strain, and above -18% as normal strain. RESULTS The mean LV-GLS value was higher in athletes than in patients with HCM and HHD with the lowest value being in the HCM group (HCM: -11.4±2.2%; HHD: -13.6±2.6%; and athletes: -15.5±2.1%; p<0.001 among groups). LV-GLS below -12.5% distinguished HCM from others with 65% sensitivity and 77% specificity [area under curve (AUC)=0.808, 95% confidence interval (CI): 0.699-0.917, p<0.001]. The median follow-up duration was 6.4±1.1 years. Overall, 11 patients (16%) died. Seven of these were in the HHD group, and four were in the HCM group. The mean GLS value in patients who died was -11.8±1.5%. LV-GLS was significantly associated with mortality after adjusting age and sex via multiple analysis (RR=0.723, 95% CI: 0.537-0.974, p=0.033). Patients with GLS below -12.5% had a higher risk of all-cause mortality compared with that of patients with GLS above -12.5% according to Kaplan-Meier survival analysis for 7 years (29% vs. 9%; p=0.032). The LV-GLS value predicts mortality with 64% sensitivity and 70% specificity with a cut-off value of -12.5 (AUC=0.740, 95% CI: 0.617-0.863, p=0.012). CONCLUSION The 2D-STE provides important information about the longitudinal systolic function of the myocardium. It may enable differentiation variable forms of LVH and predict prognosis.

Abstract
BACKGROUND Whether in volume-dependent primary hypertension, concentric left ventricular (LV) remodeling beyond hypertrophy (LVH) represents the impact of a pressure rather than a volume overload, is unclear. METHODS Using central arterial pressure, and aortic velocity and diameter measurements in the outflow tract (echocardiography), we determined the factors that associate with concentric LVH or remodeling in a community of African ancestry (n = 709) with prevalent volume-dependent primary hypertension. RESULTS Both left ventricular mass index (LVMI) and relative wall thickness (RWT) were positively and independently associated with end diastolic volume (EDV), stroke volume (SV), and peak aortic flow (Q) (P < 0.05 to <0.0001). However, neither LVMI nor RWT were positively and independently associated with systemic vascular resistance (SVR), or aortic characteristic impedance (Zc) or inversely associated with total arterial compliance (TAC). Consequently, both concentric (P < 0.0001) and eccentric (P < 0.0001) LVH were associated with similar increases in EDV, SV, and either office brachial, central arterial, or 24-hour blood pressures (BP), but neither increases in SVR or Zc nor decreases in TAC. LV RWT, but not LVMI was nevertheless independently and inversely associated with myocardial systolic function (midwall shortening and s') (P < 0.05 to <0.005) and decreases in LV systolic function were noted in concentric (P < 0.05), but not eccentric LVH. CONCLUSIONS In volume-dependent primary hypertension, concentric LVH is determined as much by volume-dependent increases in systemic flow and an enhanced BP as eccentric LVH. Concentric remodeling nevertheless reflects decreases in systolic function beyond LVH.

Evaluation of ventricular systolic function by speckle tracking technique in patients with biliary atresia before and after liver transplantation. Sci Rep 2021; 11:17807. [PMID: 34497314 PMCID: PMC8426491 DOI: 10.1038/s41598-021-97096-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 08/18/2021] [Indexed: 11/28/2022] Open
Abstract
To evaluate the ventricular function of patients with biliary atresia (BA) before and after liver transplantation using two-dimensional speckle tracking. Observational, analytical study with healthy control group, volunteers. We recruited patients from 0 to 18 years old who were candidates for liver transplantation and patients after six months of liver transplantation performed for BA from January 1997 to August 2015 at Children’s Institute of São Paulo University Medical School. The patients were submitted to a complete conventional echocardiographic study. After that, the images were captured for global longitudinal strain (GLS). A blood sample was collected for brain natriuretic peptide (BNP) level. Ejection fraction obtained by Simpson’s method was significantly higher in the hepatic pre-transplantation group (p < 0.001), as well as left atrial size (p < 0.001) and left ventricle size (p = 0.039). The left ventricular mass index was significantly higher in pre-transplantation group (p < 0.001). The left atrium volume (p = 0.008) and the left ventricular mass index (p t = 0.035) were higher in the post-transplant group. It was observed that the lower the BNP, the lower/more negative the GLS in the post-transplant group (p = 0.038 and r = 0.427). Significant reduction in the overall longitudinal strain of the left ventricle was detected before (p = 0.01) and after liver transplantation (p = 0.019). A subclinical left ventricular systolic dysfunction was evidenced by two-dimensional speckle tracking technique before and after liver transplantation, even when compared to normal values of the last pediatric meta-analysis.

Abstract
Purpose of our study was to assess the prevalence of hypertension mediated organ damage (HMOD) in healthy subjects with high-normal Blood Pressure (BP) comparing them with subjects with BP values that are considered normal (<130/85 mmHg) or indicative of hypertension (≥140/90 mmHg). Seven hundred fifty-five otherwise healthy subjects were included. HMOD was evaluated as pulse wave velocity (PWV), left ventricular mass index (LVMI), and carotid intima-media thickness (IMT) and plaque. When subjects were classified according to BP levels we found that the high-normal BP group showed intermediate values of PWV and higher values of IMT. This corresponds to intermediate prevalence of arterial stiffness, while there were no differences for increased IMT or carotid plaque. No subjects showed left ventricular hypertrophy. At multivariable analysis, the odds of having arterial stiffness or carotid HMOD in the high-normal group resulted not different to the normal group. In conclusion, in our otherwise healthy population, high-normal BP values were not related to aortic, carotid or cardiac HMOD.

Abstract
OBJECTIVES The sensitivity of ECG for detecting left ventricular hypertrophy (LVH) is low. The aim of this study was to explore a better ECG criterion for screening LVH in a large general Chinese population. DESIGN Case-control study. SETTING China Medical University in Shenyang, China. PARTICIPANTS All permanent residents in Dawa, Zhangwu and Liaoyang aged 35 years or older were invited. Participants with unqualified data, pacemaker rhythm, frequent premature ventricular beats, Wolff-Parkinson-White syndrome, complete bundle branch block, myocardial infarction or hypertrophic cardiomyopathy were excluded. A total of 10 360 subjects (4630 males) were recruited. INTERVENTIONS A novel ECG criterion (Northeast China Rural Cardiovascular Health Study (NCRCHS)) composed of different ratios of maximum R wave in lead V5 or V6 (RV5/V6), S wave in lead V3 (SV3) and R wave in lead aVL (RaVL) was proposed and validated using multiple linear regression. Receiver-operating characteristic curves were used to compare the NCRCHS criterion with traditional criteria for LVH detection. RESULTS An optimised model (15*RaVL+8*SV3+7*RV5/V6) was constructed (R2 0.192, p<0.001) with the cut-off values of 36.8 mV for males and 26.1 mV for females. The maximum area under the curve was obtained using the NCRCHS criterion (male 0.74, 95% CI 0.73 to 0.75; female 0.73, 95% CI 0.72 to 0.75), followed by Cornell voltage criterion, Sokolow-Lyon criterion, Peguero-Lo Presti criterion, multi-ethnic study of atherosclerosis (MESA)-specific criterion and Syst-Eur voltage criterion. Compared with the Cornell voltage criterion, the NCRCHS criterion had a significantly higher sensitivity for detecting LVH at the same level of specificity (p<0.05). CONCLUSIONS The NCRCHS criterion significantly improved sensitivity for LVH detection in a general Chinese population, with cut-off values of 36.8 and 26.1 mV for males and females, respectively. This criterion can detect LVH earlier and better and may prevent subsequent cardiovascular diseases.

Impact of stroke work on the ability of left ventricular mass to account for pressure effects on function in a community with prevalent systemic flow-dependent hypertension. J Hypertens 2021; 39:2092-2102.

Abstract
AIMS To determine whether the confounding influence of stroke work on left ventricular mass (LVM) limits the ability of LVM to detect hypertensive LV dysfunction in systemic flow-dependent hypertension. METHODS In a community with prevalent systemic flow-dependent hypertension (n = 709), arterial haemodynamics, LVM and LV function were determined using central arterial pressure, aortic velocity and diameter measurements in the outflow tract, and echocardiography with tissue Doppler imaging. RESULTS In multivariate models, stroke work showed markedly stronger relations with LVM index (LVMI) than blood pressure load [central arterial SBP (SBPc), backward wave pressure (Pb), 24-h SBP] (P < 0.0001 for comparisons). In contrast, although SBPc, Pb, and 24-h SBP were inversely associated with myocardial tissue shortening (s') and lengthening (e') velocity, stroke work was not. With adjustments for stroke work, positive relationships between SBPc, Pb, or 24-h SBP and LVMI were eliminated (P = 0.20 to P = 0.89), but strong relations between BP and s', e' or E/e' (P = 0.009 to P < 0.0001) remained. In mediation analysis, stroke work fully accounted for BP effects on LVMI, but explained none of the effects of BP on LV function. Hence LVMI accounted for little of the impact of BP load on LV function. Although LVMI beyond stroke work (inappropriate LVM) improved on relations between LVMI and s', it failed to improve on relations with e' or E/e' and contributed little beyond LVMI to the impact of BP on LV function. CONCLUSION In systemic flow-dependent hypertension, the impact of stroke work markedly limits the ability of LVM to account for adverse effects of hypertension on LV function.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) often have structural abnormalities of the heart due to pressure and volume overload. The aim of this study was to evaluate associations between echocardiographic parameters and renal outcomes (estimated glomerular filtration rate [eGFR] slope and progression to dialysis) in patients with stage 3-5 CKD. METHODS This longitudinal study enrolled 419 patients. Changes in renal function were assessed using the eGFR slope. Rapid renal progression was defined as an eGFR slope < -3 mL/min/1.73 m2/year, and the renal endpoint was defined as commencing dialysis. RESULTS Increased left atrial diameter (LAD), ratio of left ventricular mass to body surface area (LVM/BSA), ratio of LVM to height2.7 (LVM/ht2.7), and ratio of observed to predicted LVM (o/p LVM) were associated with eGFR slope in an adjusted model, but left ventricular ejection fraction (LVEF) was not. Furthermore, LAD ≥ 4.7 cm, LVM/BSA > 115 g/m2 in males and > 95 g/m2 in females, and LVM/ht2.7 > 48 g/ht2.7 in males and > 44 g/ht2.7 in females were correlated with progression to dialysis, but o/p LVM and LVEF were not. The maximum change in χ2 change to predict renal outcomes was observed for LAD, followed by LVM/BSA and LVM/ht2.7. CONCLUSIONS A large LAD and increased LVM, regardless of how it was measured (LVM/BSA, LVM/ht2.7 and o/p LVM), were correlated with adverse renal outcomes in patients with CKD stage 3-5. LAD had superior prognostic value to LVM and LVEF.

Abstract
Background No study has compared the clinical impact of indexation of left ventricular mass (LVM) on adverse clinical outcomes in pre-dialysis patients with chronic kidney disease (CKD). Methods We reviewed 2,101 patients from a large-scale multi-center prospective study that gathered anthropometric and echocardiographic measurements and clinical outcomes. The LVM was indexed as body surface area (LVMI-BSA) and height raised to the power of 2.7 (LVMI-H2.7). The main outcomes were composite renal and cardiovascular events and all-cause mortality. Left ventricular hypertrophy (LVH) was defined as the highest sex-specific quartile of LVMI-BSA or LVMI-H2.7. Results During a mean period of 3.5 years, 692 patients developed composite outcomes (32.9%). The area under the curve at 5 year of LVM (60.6%) for composite outcome was smaller than that for LVMI-BSA (63.2%, P <0.001) and LVMI-H2.7 (63.4%, P <0.001). The hazard ratio (HR) and 95% confidence interval (CI) per one unit increase in LVM (g), LVMI-BSA (g/m2), and LVMI-H2.7 (g/m2.7) for composite outcomes were 1.004 (1.002–1.005, P <0.001), 1.011 (1.006–1.016, P <0.001), and 1.023 (1.012–1.035, P <0.001), respectively. Patients with LVH determined by LVMI-BSA and LVMI-H2.7 (HR 1.352, 95% CI 1.123–1.626, P = 0.001) and LVH determined by only LVMI-BSA (HR 1.908, 95% CI 1.233–2.953, P = 0.004) showed an independent increase in the risk of composite-outcome development, when compared with patients without LVH, according to LVMI-BSA and LVMI-H2.7. Conclusion Indexation of LVM improved the prediction of adverse outcomes. BSA may be as useful as height2.7 in indexing of LVM for predicting adverse outcomes in pre-dialysis patients with CKD.

Abstract
Background To investigate the influence of hyperhomocysteinemia (HHcy) and metabolic syndrome (MetS) on left ventricular hypertrophy (LVH) in residents in rural Northeast China. Methods We performed a cross-sectional baseline data analysis of 6837 subjects (mean age: 54 ± 10 years) recruited from a rural area of China. Anthropometric indicators were measured according to standard methods. MetS was defined by the modified ATP III criteria. HHcy was defined according to the WHO standard: an Hcy level > 15 μmol/L representing HHcy. Four groups were defined: non-HHcy & non-MetS, HHcy & non-MetS, MetS & non-HHcy and HHcy & MetS. Results The left ventricular mass index for height2.7 (LVMH2.7) in both sexes was significantly higher in the HHcy & MetS group than in the non-HHcy & non-MetS group (females: 51.23 ± 16.34 vs. 40.09 ± 10.55 g-2.7, P < 0.001; males: 48.67 ± 12.24 g-2.7 vs. 42.42 ± 11.38 g-2.7, P < 0.001). A similar result was observed in those groups when using the left ventricular mass index (LVMI) for body surface area to define LVH (females: 103.58 ± 31.92 g− 2 vs. 86.63 ± 20.47 g− 2, P < 0.001; males: 106.10 ± 24.69 g− 2 vs. 98.16 ± 23.29 g− 2, P < 0.001). The results of multiple regression analysis indicated that the HHcy & MetS group had a higher risk of LVH than the other three groups (OR: 1.628 for LVMI, P < 0.001, OR: 2.433 for LVMH2.7, P < 0.001). Moreover, subjects in the HHcy & non-MetS group [OR (95% CI): 1.297 (1.058, 1.591) for LVMI, P < 0.05; OR (95% CI): 1.248 (1.044, 1.492) for LVMH2.7, P < 0.05] also had a statistically greater risk of LVH than subjects in the non-HHcy & non-MetS group. The HHcy & non-MetS group was also found to be significantly and independently associated with LVH. Conclusion Hyperhomocysteinemia has an independent effect on LVH. The combined effect of MetS and hyperhomocysteinemia might increase the strength of the abovementioned effects.

Abstract
Abstract
Aims
Accurate assessment of aortic dimensions can be achieved using contrast-enhanced computed tomography. The aim of this study was to define normal values and determinants of aortic dimensions throughout multiple key anatomical landmarks of the aorta in healthy individuals from the Copenhagen General Population Study.
Methods and results
The study group consisted of 902 healthy subjects selected from 3000 adults undergoing cardiovascular thoracic and abdominal computed tomography-angiography (CTA), where systematic measurements of aortic dimensions were performed retrospectively. Individuals included were without any of the following predefined cardiovascular risk factors: (i) self-reported angina pectoris; (ii) hypertension; (iii) hypercholesterolaemia; (iv) taking cardiovascular prescribed medication including diuretics, statins, or aspirin; (v) overweight (defined as body mass index ≥30 kg/m2); (vi) diabetes mellitus (self-reported or blood glucose >8 mmol/L); and (vii) chronic obstructive pulmonary disease. Maximal aortic diameters were measured at seven aortic regions: sinuses of Valsalva, sinotubular junction, ascending aorta, mid-descending aorta, abdominal aorta at the diaphragm, abdominal aorta at the coeliac trunk, and infrarenal abdominal aorta. Median age was 52 years, and 396 (40%) were men. Men had significantly larger aortic diameters at all levels compared with women (P < 0.001). Multivariable analysis revealed that sex, age, and body surface area were associated with increasing aortic dimensions.
Conclusion
Normal values of maximal aortic dimensions at key aortic anatomical locations by contrast-enhanced CTA have been defined. Age, sex, and body surface area were significantly associated with these measures at all levels of aorta. Aortic dimensions follow an almost identical pattern throughout the vessel regardless of sex.

Abstract
BACKGROUND Cardiac size measurements require indexing to body size. Allometric indexing has been investigated in Caucasian populations but a range of different values for the so-called allometric power exponent (b) have been proposed, with uncertainty as to whether allometry offers clinical utility above body surface area (BSA)-based indexing. We derived optimal values for b in normal echocardiograms and validated them externally in cardiac patients. METHODS AND RESULTS Values for b were derived in healthy adult Chinese males (n=1,541), with optimal b for left ventricular mass (LVM) of 1.66 (95% confidence interval 1.41-1.92). LV hypertrophy (LVH) defined as indexed LVM >75 g/m1.66 was associated with adverse outcomes in an external validation cohort (n=738) of patients with acute coronary syndrome (odds ratio for reinfarction: 2.4 (1.1-5.4)). In contrast, LVH defined by BSA-based indexing or allometry using exponent 2.7 exhibited no significant association with outcomes (P=NS for both). Cardiac longitudinal function also varied with body size: septal and RV free wall s', TAPSE and lateral e' all scaled allometrically (b=0.3-0.9). CONCLUSIONS An optimal b of 1.66 for LVM in healthy Chinese was found to validate well, with superior clinical utility both to that of BSA-based indexing and to b=2.7. The effect of allometric indexing of cardiac function requires further study.

Abstract
BACKGROUND Although abnormal left ventricular geometric patterns have prognostic value for morbidity and mortality, their possible association with silent cerebrovascular disease has not been extensively evaluated. METHODS We examined 665 participants in the CABL study who underwent transthoracic echocardiography and brain magnetic resonance imaging. Participants were divided into 4 geometric patterns: normal geometry (n=397), concentric remodeling (n=89), eccentric hypertrophy (n=126), and concentric hypertrophy (n=53). Subclinical cerebrovascular disease was defined as silent brain infarcts (SBIs) and white matter hyperintensity volume (WMHV; expressed as log-transformed percentage of the total cranial volume). RESULTS Silent brain infarcts were observed in 94 participants (14%). Mean log-WMHV was -0.97±0.93. Concentric hypertrophy carried the greatest risk for both SBI (adjusted odds ratio [OR] 3.39, P<.001) and upper quartile of log-WMHV (adjusted OR 3.35, P<.001), followed by eccentric hypertrophy (adjusted ORs 2.52 [P=.001 for SBI] and 1.96 [P=.004] for log-WMHV). Concentric remodeling was not associated with subclinical brain disease. In subgroup analyses, concentric and eccentric hypertrophies were significantly associated with SBI and WMHV in both genders and nonobese participants, but differed for SBI by age (all ages for eccentric hypertrophy, only patients ≥70years for concentric hypertrophy) and by race-ethnicity (Hispanics for eccentric hypertrophy, blacks for concentric hypertrophy; no association in whites). CONCLUSIONS Left ventricular hypertrophy, with both eccentric and concentric patterns, was significantly associated with subclinical cerebrovascular disease in a multiethnic stroke-free general population. Left ventricular geometric patterns may carry different risks for silent cerebrovascular disease in different sex, age, race-ethnic, and body size subgroups.

Abstract
BACKGROUND Left ventricular hypertrophy (LVH) is a risk factor for all-cause mortality. Left ventricular (LV) mass is usually indexed for normalizing the value to the patients phenotype and a correction by body surface area (BSA) is widely utilized being the only approved one according to the last echocardiography guidelines. However indexing LV mass by BSA may cause an underestimation of LVH prevalence in obese subjects and many authors have utilized in the obese subset of patients a correction by height2.7. The aim of our study was to quantify the number of obese patients who, despite having an increased LV mass, fall in the range of normality because they do not reach the LVH cutoff according to the new guidelines. METHODS We reviewed the echocardiograms of 384 white women free from cardiovascular disease. Ninety-six patients (25%) were obese: among them 42 had mild obesity and 54 had moderate or severe obesity. RESULTS In the obese group, the prevalence of LVH using the absolute LV mass value was similar to the one obtained with the height2.7 correction while a significant smaller number of patients had LVH according to BSA correction. Our study confirms that the method used for correcting LV mass significantly influences the diagnosis of LVH in a non-selected female population: using body surface area underestimates the prevalence of LVH as compared to allometric measures in the obese subset of patients. CONCLUSION We recommend that height2.7 be used for LV mass correction in obese patients.

Abstract
Hypertension (HTN) is present in nearly 50 million individuals, or approximately 29% of the adult US population. The prevalence of HTN is higher in men, increases with age, and varies among ethnic groups. Alterations of left ventricular structure and function can be present in patients with HTN and accurately characterized by echocardiography. The presence of left ventricular hypertrophy with increased left ventricular mass has prognostic implications in patients with HTN.

Abstract
AIM We estimated the risk of cardiovascular and all-cause mortality associated with left ventricular geometric patterns, as defined by a new classification system proposed by the Dallas Heart Study, in 1716 representatives of the general population of Monza enrolled in the Pressioni Monitorate e Loro Associazioni (PAMELA) study. METHODS Cut-points for abnormal left ventricular geometric patterns were derived from reference values of the healthy fraction of the PAMELA population by combining left ventricular mass (LVM) index, left ventricular diameter and relative wall thickness. Death certificates were collected over an average 211 months follow-up period. RESULTS During follow-up, 89 fatal cardiovascular events and 264 all-cause deaths were recorded. Concentric remodelling was the most common left ventricular geometric abnormality (9.4%) followed by eccentric nondilated left ventricular hypertrophy (LVH) (6.3%), concentric LVH (4.6%) and eccentric dilated LVH (3.5%). Compared with normal left ventricular geometry, concentric LVH [hazard ratio 2.20, 95% confidence interval (95% CI) 1.44-3.37, P < 0.0003], eccentric dilated LVH (hazard ratio 1.90, 95% CI 1.17-3.08, P = 0.009) and eccentric nondilated LVH (hazard ratio 1.57, 95% CI 1.07-2.31, P = 0.02) predicted the risk of cardiovascular mortality, after adjustment for baseline covariates, including ambulatory blood pressure. Similar findings were observed for all-cause mortality. Only concentric LVH maintained a significant prognostic value for both outcomes after adjustment for baseline differences in LVM index. CONCLUSION The new classification system of left ventricular geometric patterns may improve mortality risk stratification in a general population. The risk is markedly dependent on LVM values; only concentric LVH provides a prognostic information beyond that conveyed by cardiac mass.

Abstract
AIM We estimated the risk of cardiovascular and all-cause mortality associated with left ventricular hypertrophy (LVH) as assessed by left ventricular mass (LVM), normalized by various indexation methods in 1716 representatives of the general population of Monza, enrolled in the Pressioni Arteriose Monitorate E Loro Associazioni study. METHODS LVH was defined according to four sex-specific criteria derived from the upper limits of normality for LVM index in the healthy normotensive fraction of the Pressioni Arteriose Monitorate E Loro Associazioni population. Death certificates were collected over an average 211 months of follow-up. RESULTS During follow-up, 89 fatal cardiovascular events and 264 all-cause deaths were observed. LVH prevalence rates in the whole population ranged from 14.2% [LVM/body surface area (BSA)] to 18.0% (LVM/height). Adjusted risk (for baseline covariates, including ambulatory blood pressure) of cardiovascular mortality was increased in patients with LVH, regardless of the indexation type: LVH/BSA [hazard ratio 3.19, 95% confidence interval (CI) 2.02-5.06, P < 0.0001], LVH/height (hazard ratio 2.39, 95% CI 1.51-3.78, P = 0.0002), LVH/height (hazard ratio 2.38, 95% CI 1.50-3.76, P = 0.0002), LVH/height (hazard ratio 2.28, 95% CI 1.44-3.60 P = 0.0004). Similar findings were observed for all-cause mortality and when LVM was assessed as a continuous variable. The fraction of patients (5%) classified into the LVH group by height, but not by BSA, had a mild increased LVM index and showed no increased risk. CONCLUSIONS LVH, irrespective of indexation methods for LVM, confers an increased risk of cardiovascular and all-cause mortality in the general population. LVH, detected by height-based indexes, but not by BSA-based criteria, was not associated with increased mortality; this finding, however, was based on a small group of patients and will deserve further investigations.

Abstract
Background Cardiovascular disease (CVD) is considered a public health burden and most common cause of mortality in all over the world. The latency time for developing CVD may be several decades. the objective of this study was to examine the relationship between body composition and Left Ventriculare Mass Index (LVMI) in newly diognosed hypertensive patients. Methods We enrolled 120 new-diagnosed hypertensive patients (mean age 45 ± 8 years) who admitted to our nephrology clinic. Body fat percentage (BFP) was measured by bioelectrical impedance (BIA). Echocardiography examinations were performed for all patients. Results Mean values of Waist hip ratio, Body mass ındex, Body fat percentage, Systolic blood pressure, Diastolic blood pressure were significantly higher for females than males (all p values <0.05). The female patients had higher LVMI than male patients (94.8 ± 13.1 vs 89.2 ± 14.6, p < 0.05). The study patients were divided into 3 groups according to their BFP defined by BIA. Group 3 patients, who exhibited higher body fat, had significantly higher BMI (p < 0,05), total leukocyte count (p < 0.05), CRP (p < 0.05), triglyceride (p < 0.05), and female predominance. Group 3 patients were statistically older than group 1 patients (46.2 vs. 40.6 years, p < 0.05). Additionally, LVMI levels were higher in Group 3 than Group 1 (p < 0.05) (Table 3). In logistic regression analysis, independent factors affecting LVMI were age, weight, gender and BFP (all p values were <0.05). Conclusions BFP was associated with higher LVMI, in newly diognosed hypertensive patients. Its use results in significantly lower proportions of individuals with LVH in the population, in particular among hypertensive and the obese patients.

Abstract
In the Losartan Intervention for End Point Reduction in Hypertension (LIFE) study, 4.8 years' losartan- versus atenolol-based antihypertensive treatment reduced left ventricular hypertrophy and cardiovascular end points, including cardiovascular death and stroke. However, there was no difference in myocardial infarction (MI), possibly related to greater reduction in myocardial oxygen demand by atenolol-based treatment. Myocardial oxygen demand was assessed indirectly by the left ventricular mass×wall stress×heart rate (triple product) in 905 LIFE participants. The triple product was included as time-varying covariate in Cox models assessing predictors of the LIFE primary composite end point (cardiovascular death, MI, or stroke), its individual components, and all-cause mortality. At baseline, the triple product in both treatment groups was, compared with normal adults, elevated in 70% of patients. During randomized treatment, the triple product was reduced more by atenolol, with prevalences of elevated triple product of 39% versus 51% on losartan (both P≤0.001). In Cox regression analyses adjusting for age, smoking, diabetes mellitus, and prior stroke, MI, and heart failure, 1 SD lower triple product was associated with 23% (95% confidence interval 13%-32%) fewer composite end points, 31% (18%-41%) less cardiovascular mortality, 30% (15%-41%) lower MI, and 22% (11%-33%) lower all-cause mortality (all P≤0.001), without association with stroke (P=0.34). Although losartan-based therapy reduced ventricular mass more, greater heart rate reduction with atenolol resulted in larger reduction of the triple product. Lower triple product during antihypertensive treatment was strongly, independently associated with lower rates of the LIFE primary composite end point, cardiovascular death, and MI, but not stroke.

Combination of hyperuricemia and metabolic syndrome is an independent and powerful predictor for left ventricular hypertrophy in rural Chinese. ANNALES D'ENDOCRINOLOGIE 2015; 76:264-71. [PMID: 26141680 DOI: 10.1016/j.ando.2015.01.002] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2014] [Revised: 12/20/2014] [Accepted: 01/09/2015] [Indexed: 01/24/2023]
Abstract
OBJECTIVES To investigate the influence of MetS (metabolic syndrome) in combination with hyperuricemia on left ventricular hypertrophy (LVH) in residents in the rural area of Northeast China. METHODS We performed a cross-sectional baseline data analysis of 11,170 subjects (mean age: 54±11years) recruited from the rural area of China. Anthropometric indicators were measured according to standard methods. MetS was defined by the ATP III modified criteria. Hyperuricemia was defined according to sex-specific serum uric acid levels (SUA): SUA≥7.0mg/dL for male and≥6.0mg/dL for female. Four groups were listed: normouricemia non-MetS, hyperuricemia non-MetS, MetS normouricemia and hyperuricemia MetS. RESULTS Left ventricular mass index for height(2.7) (LVMH(2.7)) in female was significantly higher in hyperuricemia MetS group than that in normouricemia non-MetS (52.43±16.60 vs. 40.04±10.72g/m(2.7), P<0.001) group. Similar result was observed in men (48.93±13.17g/m(2.7) vs. 43.63±11.90g/m(2.7), P<0.001). The result of multiple regression analysis indicated that hyperuricemia MetS group had higher risk of LVH than other three groups (OR: 3.427 for female, P<0.001, OR: 1.987 for male, P<0.001). Moreover, female subjects in MetS normouricemia group [OR (95% CI): 2.313 (1.991-2.686)] had greater risk of LVH than that in hyperuricemia non-MetS group [OR (95% CI): 1.917 (1.166-3.151)]. Hyperuricemia non-MetS was found to be significantly and independently associated with LVH in women, but not in men. CONCLUSION Our study finds that the combination of hyperuricemia and MetS are independent and powerful predictor for LVH in rural area of Northeast Chinese. Women with MetS in combination with hyperuricemia have higher risk of LVH than men. It seems that MetS has greater effect on LVH than hyperuricemia does in women but not in men.

Abstract
OBJECTIVES To examine the contribution of body size, biological maturation, and nonelite sports participation to longitudinal changes of left ventricular mass (LVM) in healthy boys. METHODS One hundred and ten boys (11.0-14.5 years at baseline) were assessed biannually for 2 years. Stature, body mass, and four skinfolds were measured. Lean body mass (LBM) was estimated. Biological maturation was assessed as years from age at peak height velocity (APHV). Sports participation was assessed by questionnaire. LVM was obtained from M-mode echocardiograms using two-dimensional images. To account for the repeated measures within individual nature of longitudinal data, multilevel random effects regression analyses were used in the analysis. RESULTS LVM increased on average 42 ± 18 g from 11 to 15 years (P < 0.05) and 76 ± 14 g from 3.5 years pre-APHV to 1.5 years post-APHV (P < 0.05). The multilevel model with the best statistical fit (Model B) showed that changes of 1 cm in stature, 1 year post-APHV, and 1 kg of LBM predicts 4.7, 0.5, and 1 g of LVM (P < 0.05), respectively. CONCLUSIONS Among healthy, male adolescents aged 11-15 years individual differences in growth and biological maturation influence growth of LVM. Subcutaneous adiposity and sports participation were not associated with greater LVM.

Abstract
Residual renal function (RRF) is associated with left ventricular (LV) hypertrophy as well as all-cause and cardiovascular (CV) mortality in patients with end-stage renal disease. However, no studies have yet examined the serial changes in echocardiographic findings according to the rate of RRF decline in incident dialysis patients. A total of 81 patients who started peritoneal dialysis (PD) between 2005 and 2012 at Yonsei University Health System, Seoul, South Korea, and who underwent baseline and follow-up echocardiography within the first year of PD were recruited. Patients were dichotomized into "faster" and "slower" RRF decline groups according to the median values of RRF decline slope (-1.60 mL/min/y/1.73 m(2)). Baseline RRF and echocardiographic parameters were comparable between the 2 groups. During the first year of PD, there were no significant changes in LV end-diastolic volume index (LVEDVI), left atrial volume index (LAVI), or LV mass index (LVMI) in the "faster" RRT decline group, while these indices decreased in the "slower" RRT decline group. The rate of RRF decline was a significant determinant of 1-year changes in LVEDVI, LAVI, and LVMI. The linear mixed model further confirmed that there were significant differences in the changes in LVEDVI, LAVI, and LVMI between the 2 groups (P = 0.047, 0.048, and 0.001, respectively). During a mean follow-up duration of 31.9 months, 4 (4.9%) patients died. Compared with the "slower" RRF decline group, CV composite (20.29/100 vs 7.18/100 patient-years [PY], P = 0.098), technique failure (18.80/100 vs 4.19/100 PY, P = 0.006), and PD peritonitis (15.73/100 vs 4.95/100 PY, P = 0.064) developed more frequently in patients with "faster" RRF decline rate. On multivariate Cox regression analysis, patients with "faster" RRF decline rate showed 4.82-, 4.44-, and 7.37-fold higher risks, respectively, for each clinical outcome. Preservation of RRF is important for conserving cardiac performance, resulting in an improvement in clinical outcomes of incident PD patients.

Abstract
The American Academy of Pediatrics (AAP) recommends that any child diagnosed with hypertension have an echocardiogram to evaluate for the presence of left-ventricular (LV) hypertrophy (LVH) and advocates that LVH is an indication to initiate or intensify antihypertensive therapy. However, there is no consensus on the ideal method of defining LVH in the pediatric population. Many pediatric cardiologists rely on wall-thickness z-score of the LV posterior wall and/or interventricular septum to determine LVH. Yet, the AAP advocates using LV mass indexed to 2.7 (LVMI(2.7)) ≥ 51 g/m(2.7) to diagnose LVH. Recently, age-specific reference values for LVMI ≥ 95% were developed. The objective of the study was to determine the concordance between diagnosis of LVH by wall-thickness z-score and diagnosis by LVMI(2.7) criteria. A retrospective chart review was performed for subjects diagnosed with hypertension at a single tertiary care center (2009-2012). Echocardiogram reports were reviewed, and assessment of LVH was recorded. Diagnosis of LVH was assigned to each report reviewed according to three criteria: (1) LV wall-thickness z-score > 2.00; (2) age-specific reference values for LVMI(2.7) > 95th percentile; and (3) LVMI(2.7) > 51 g/m(2.7). Cohen's kappa statistic was used as a measurement of agreement between diagnosis by wall-thickness z-score and diagnosis using LVMI(2.7). A total of 159 echocardiograms in 109 subjects were reviewed. Subjects included 31 females and 77 males, age 13.2 ± 4.4 years, and 39 (42%) with a diagnosis of secondary hypertension. LVH was diagnosed in 31 cases (20%) based on increased wall-thickness z-score. Using LVMI(2.7) > 95%, LVH was found in 75 (47%) cases (mean LVMI(2.7)42.3 ± 17.2 g/m(2.7) [range 11.0-111 g/m(2.7)]). The wall-thickness z-score method agreed with LVMI(2.7) > 95% diagnosis 71% of the time (kappa 0.4). Using LVH criteria of LVMI(2.7) ≥ 51 g/m(2.7), 33 (21%) subjects were diagnosed with LVH. There was 79% agreement in the diagnosis of LVH between the wall-thickness z-score method and LVMI(2.7) > 51 g/m(2.7) (kappa 0.37). There is poor concordance between the diagnosis of LVH on echocardiogram reports using wall-thickness z-score and diagnosis of LVH using LVMI(2.7) criteria. It is important to establish a consensus method for diagnosing LVH because of the high frequency of cardiovascular complications in children with hypertension.

Abstract
BACKGROUND Framingham risk score (FRS) underestimates risk in young adults. Left ventricular mass (LVM) relates to cardiovascular disease (CVD), with unclear value in youth. In a young biracial cohort, we investigate how FRS predicts CVD over 20 years and the incremental value of LVM. We also explore the predictive ability of different cut-points for hypertrophy. METHODS We assessed FRS and echocardiography-derived LVM (indexed by body surface area or height2.7) from 3980 African-American and white Coronary Artery Risk Development in Young Adults (CARDIA) participants (1990-1991); and followed over 20 years for a combined endpoint: cardiovascular death; nonfatal myocardial infarction, heart failure, cerebrovascular disease, and peripheral artery disease. We assessed the predictive ability of FRS for CVD and also calibration, discrimination, and net reclassification improvement for adding LVM to FRS. RESULTS Mean age was 30±4 years, 46% males, and 52% white. Event incidence (n=118) across FRS groups was, respectively, 1.3%, 5.4%, and 23.1% (p<0.001); and was 1.4%, 1.3%, 3.7%, and 5.4% (p<0.001) across quartiles of LVM (cut-points 117 g, 144 g, and 176 g). LVM predicted CVD independently of FRS, with the best performance in normal weight participants. Adding LVM to FRS modestly increased discrimination and had a statistically significant reclassification. The 85th percentile (≥116 g/m2 for men; ≥96 g/m2 for women) showed event prediction more robust than currently recommended cut-points for hypertrophy. CONCLUSION In a biracial cohort of young adults, FRS and LVM are helpful independent predictors of CVD. LVM can modestly improve discrimination and reclassify participants beyond FRS. Currently recommended cut-points for hypertrophy may be too high for young adults.

Abstract
Periodic limb movements during sleep (PLMS) is a sleep-related movement disorder characterized by repetitive limb movements during sleep, seen predominantly in the legs but also occasionally involving the arms. These movements may be associated with arousals that can lead to increases in sympathetic tone, resulting in tachycardia and elevated systolic blood pressure. Chronic sustained tachycardia and elevated systolic blood pressure are known to be associated with the development of arrhythmias, hypertension, left ventricular hypertrophy, and congestive heart failure. However, the data are not entirely clear on whether untreated PLMS is associated with these cardiovascular risks. This review examines the current evidence on whether PLMS has any effect on the cardiovascular system.

Abstract
BACKGROUND The prognostic importance of anemia for cardiovascular (CV) events and mortality has been extensively investigated. However, little is known about the impact of transferrin saturation (TSAT), a marker reflecting the availability of iron for erythropoiesis, on clinical outcome in dialysis patients. METHODS A total of 879 anemic incident dialysis patients were recruited from the Clinical Research Center for End-Stage Renal Disease in Korea and were divided into 3 groups according to baseline TSAT of ≤20%, 20-40%, and >40%. RESULTS There were no differences in hemoglobin levels and the proportion of patients on erythropoiesis-stimulating agents or iron supplements among the 3 groups. During a mean follow-up duration of 19.3 months, 51 (5.8%) patients died. CV composite (11.71 vs. 5.55 events/100 patient-years, P = 0.001) and all-cause mortality rates (5.38 vs. 2.31 events/100 patient-years, P = 0.016) were significantly higher in patients with TSAT ≤20% compared to those with TSAT 20-40% (reference group). Cox regression analysis revealed that patients with TSAT ≤20% had 1.62- and 2.19-fold higher risks for CV composite outcome (P = 0.046) and all-cause mortality (P = 0.030). Moreover, TSAT ≤20% was significantly associated with left ventricular hypertrophy [odds ratio (OR) = 1.46], high-sensitivity C-reactive protein ≥3 mg/dL (OR = 2.09), N-terminal pro B-type natriuretic peptide ≥10000 pg/mL (OR = 2.04), and troponin-T≥0.1 ng/mL (OR = 2.02), on logistic regression analysis. CONCLUSIONS Low TSAT was a significant independent risk factor for adverse clinical outcome in incident dialysis patients with anemia, which may be partly attributed to cardiac dysfunction and inflammation.

Abstract
UNLABELLED Left ventricular hypertrophy (LVH) has been described in the context of cirrhotic cardiomyopathy. The influence of LVH on survival of liver transplant (LT) recipients has not been clarified. Therefore, we evaluated the effect of LVH on survival in LT recipients. In total, data from 352 LT patients were analyzed. LVH was diagnosed by echocardiographic measurement of left ventricular wall thickness before LT. Patients were followed up for a mean of 4.2 yr. LVH was diagnosed in 135 (38.4%) patients. Patients with LVH had significantly more frequently male gender (p = 0.046), diastolic dysfunction (p < 0.001), and hepatocellular carcinoma (HCC; p = 0.004). Furthermore, LVH patients were older (p < 0.001) and had a higher body mass index (BMI; p = 0.001). There was no difference in frequency of arterial hypertension, pre-transplant diabetes mellitus, or etiology of liver cirrhosis. Patients without LVH had a better survival (log rank: p = 0.05) compared with LVH patients. In a multivariate Cox regression LVH (p = 0.031), end-stage renal disease (ESRD; p = 0.003) and lack of arterial hypertension (p = 0.004) but not MELD score (p = 0.885) were associated with poorer survival. CONCLUSION LVH is frequently diagnosed in patients on the waiting list and influences survival after LT.

Abstract
The function of the transplanted heart will be affected by acute allograft rejection, chronic rejection, high blood pressure and so on, which may induce the reconstruction of the left ventricle and the increase of left ventricular mass (LVM), and eventually lead to left ventricular hypertrophy that will significantly affect the prognosis of heart transplantation (HT). The purpose of this study was to dynamically monitor the changes of left ventricular geometric patterns after HT using two-dimensional echocardiography and to understand the remodeling process and its possible influencing factors. The left ventricular internal diameter, interventricular septal wall thickness, posterior wall thickness at end diastole were measured and the relative wall thickness (RWT), left ventricular mass, left ventricular mass index were calculated respectively in 34 HT patients and 34 healthy volunteers by two-dimensional echocardiography. The type of left ventricular geometry was identified based on the echocardiographic determination of LVM index (LVMI) and RWT. The HT patients were divided into three groups according to the time length after surgery: A (3 months postoperatively), B (6 months postoperatively) and C (12 months postoperatively). We compared the parameters of left ventricle between HT group and normal control group, and explored the risk factors causing the increase of LVM. The results showed that 4 patients (16%) in group A had concentric remodeling. Nine patients (34.62%) in group B had reconstruction, including 5 cases of concentric remodeling, 2 cases of concentric hypertrophy and 2 cases of eccentric hypertrophy. The hypertrophy incidence rate was 15.4% in group B. 15 patients (62.5%) had reconstruction in group C, including 9 cases of concentric remodeling, 5 cases of concentric hypertrophy, and 1 case of eccentric hypertrophy. The prevalence of hypertrophy was 25%. Multivariate analysis showed that hypertension and acute rejection history were the risk factors that resulted in left ventricular hypertrophy. It is concluded that the left ventricular remodeling occurs following cardiac transplantation at an early stage and the incidence of left ventricular hypertrophy increases with survival time. In this study, the one-year prevalence of left ventricular hypertrophy was 25% after surgery. Hypertension and acute rejection history are risk factors that can predict the left ventricular hypertrophy.

Abstract
Obesity is characterized by the disproportionate growth of the components of body size, including adipose tissue and lean body mass. Left ventricular (LV) hypertrophy often develops, due to the coexistence of hemodynamic (cardiac workload) and non-hemodynamic components (including body composition and activity of visceral fat). While the hypertrophy of cardiomyocytes is produced by the hemodynamic load, through sarcomeric replication, there is a parallel growth of non-muscular myocardial components, including interstitial fat infiltration and accumulation of triglycerides in the contractile elements, which are thought to influence LV geometric pattern. Thus, pure intervention on hemodynamic load is unlikely to result in effective reduction of LV hypertrophy in obese. We review pathophysiology and prevalence of LV hypertrophy in obesity, with specific attention to LV geometric abnormalities and relations with body size.

Abstract
BACKGROUND AND AIM Experimentally uric acid may induce cardiomyocyte growth and interstitial fibrosis of the heart. However, clinical studies exploring the relationship between serum uric acid (SUA) and left ventricular (LV) mass yielded conflicting results. The aim of our study was to evaluate the relationships between SUA and LV mass in a large group of Caucasian essential hypertensive subjects. METHODS AND RESULTS We enrolled 534 hypertensive patients free of cardiovascular complications and without severe renal insufficiency. In all subjects routine blood chemistry, including SUA determination, echocardiographic examination and 24 h ambulatory blood pressure (BP) monitoring were obtained. In the overall population we observed no significant correlation of SUA with LV mass indexed for height(2.7) (LVMH(2.7)) (r = 0.074). When the same relationship was analysed separately in men and women, we found a statistically significant correlation in female gender (r = 0.27; p < 0.001), but not in males (r = -0.042; p = NS). When we grouped the study population in sex-specific tertiles of SUA, an increase in LVMH(2.7) was observed in the highest tertiles in women (44.5 ± 15.6 vs 47.5 ± 16 vs 55.9 ± 22.2 g/m(2.7); p < 0.001), but not in men. The association between SUA and LVMH(2.7) in women lost statistical significance in multiple regression analyses, after adjustment for age, 24 h systolic BP, body mass index, serum creatinine and other potential confounders. CONCLUSIONS Our findings do not support an independent association between SUA and LV mass in Caucasian men and women with arterial hypertension.

Abstract
Background: Left ventricular hypertrophy (LVH) as a marker of cardiac damage in hypertension has important prognostic implications. With high prevalence of hypertension in Nigeria and the untoward effect of LVH, it is essential that the prevalence of LVH be determined. Aims: To determine prevalence of LVH and its severity in clinical practice among hypertensive patients referred for echocardiographic assessment in Nigeria. Materials and Methods: Devereux and Troy formulae were used to calculate echocardiographic LV mass (LVM) in 401 subjects and thereafter normalized to body surface area (BSA), heigth2 (ht2) and height2.7 (ht2.7) to define LVH to standard gender-specific thresholds. Results: Mean age was 53.22 ± 16.56 years (male = 53.18 ± 15.80; female = 53.27 ± 17.43; P = 0.958) with a male:female ratio of 1.13:1. Prevalence rates of LVH ranged between 38.9–51.3% using the Devereux Formula and 62.4–71.1% using the Troy formula. LVM/(ht2.7) using the Troy formula gave the highest prevalence rate of LVH. Majority of the patients with LVH had severe form of hypertrophy with the prevalence rates ranging from 22.3% (LVM/BSA; Devereux formula) to 47.1% (LVM/ht2.7; Troy formula). Conclusion: Prevalence of LVH by any echocardiographic criteria is high. There is a need to come to a consensus on the best formula and indexing variables, that will unify the reporting of LVH.

Abstract
BACKGROUND Sleep disturbance caused by obstructive sleep apnea is recognized as a contributing factor to adverse cardiovascular outcomes. However, the effect of restless legs syndrome, another common cause of fragmented sleep, on cardiac structure, function, and long-term outcomes is not known. The aim of this study was to assess the effect of frequent leg movement during sleep on cardiac structure and outcomes in patients with restless legs syndrome. METHODS In our retrospective study, patients with restless legs syndrome referred for polysomnography were divided into those with frequent (periodic movement index > 35/hour) and infrequent (≤ 35/hour) leg movement during sleep. Long-term outcomes were determined using Kaplan-Meier and logistic regression models. RESULTS Of 584 patients, 47% had a periodic movement index > 35/hour. Despite similarly preserved left ventricular ejection fraction, the group with periodic movement index > 35/hour had significantly higher left ventricular mass and mass index, reflective of left ventricular hypertrophy (LVH). There were no significant baseline differences in the proportion of patients with hypertension, diabetes, hyperlipidemia, prior myocardial infarction, stroke or heart failure, or the use of antihypertensive medications between the groups. Patients with frequent periodic movement index were older, predominantly male, and had more prevalent coronary artery disease and atrial fibrillation. However, on multivariate analysis, periodic movement index > 35/hour remained the strongest predictor of LVH (odds ratio, 2.45; 95% confidence interval, 1.67-3.59; P < .001). Advanced age, female sex, and apnea-hypopnea index were other predictors of LVH. Patients with periodic movement index > 35/hour had significantly higher rates of heart failure and mortality over median 33-month follow-up. CONCLUSIONS Frequent periodic leg movement during sleep is an independent predictor of severe LVH and is associated with increased cardiovascular morbidity and mortality.

Abstract
BACKGROUND Left atrial enlargement (LAE) reflects diastolic dysfunction and predicts mortality in end-stage renal disease patients. However, little is known of its prevalence and factors associated with subclinical LAE in earlier stages of chronic kidney disease (CKD). METHODS We conducted a prospective, cross-sectional study in 261 Stage 3-5 non-dialysis CKD patients without symptomatic cardiovascular disease with two-dimensional echocardiography performed to estimate left atrial volume index and other cardiac parameters. RESULTS One hundred and nine (41.8%) patients had LAE. Mild and moderate/severe LAEs were observed in 22.9 and 41.3% of patients with left ventricular (LV) hypertrophy (n = 109) versus 13.2 and 12.5% of patients with no LV hypertrophy (n = 152), respectively (P < 0.001). On univariate analysis, plasma sodium concentration showed a significant association with LAE [odds ratio (OR) 1.22, 95% confidence interval (95% CI) 1.09-1.37; P = 0.001]. In the stepwise multiple logistic regression, plasma sodium concentration emerged as one of the most significant factors associated with LAE (adjusted OR 1.29, 95% CI 1.14-1.47; P < 0.001]. Its significance was well maintained (adjusted OR 1.23, 95% CI 1.07-1.43; P = 0.005) when including LV mass and volume index and N-terminal pro-brain natriuretic peptide in the model, while blood haemoglobin and systolic blood pressure were displaced. CONCLUSIONS This study for the first time alerted to a very high prevalence of subclinical LAE and reported a strong novel, independent relationship between plasma sodium concentration and subclinical LAE in Stage 3-5 CKD patients. Longitudinal studies are needed to establish causality between high plasma sodium concentration and LAE and their usefulness as therapeutic targets in CKD.

Abstract
We sought to determine whether childhood obesity is associated with increased aortic stiffness by measuring the biophysical properties of the aorta in obese children using a noninvasive echocardiographic Doppler method. Increased aortic stiffness is a strong predictor of future cardiovascular events and mortality in adults. Obesity is known to be associated with increased aortic stiffness and arterial disease in adults. We prospectively evaluated a cohort of obese children (n = 61) and compared them to normal-weight controls (n = 55). The anthropometric data were recorded. The pulsewave velocity (PWV), aortic input impedance (Zi), characteristic impedance (Zc), arterial pressure-strain elastic modulus (Ep), arterial wall stiffness index (B index), and peak aortic velocity were calculated. We correlated our echocardiographic Doppler findings with the lipid levels. We assessed the left ventricular (LV) dimensions and standard measures of cardiac function. Cardiopulmonary exercise testing was performed on all obese children. Compared to normal-weight children, obese children had a greater PWV, Zc, B index, Ep, and peak aortic velocity. Obese children had greater systolic blood pressure than normal-weight children but no difference in diastolic blood pressure. The LV dimensions and standard measures of cardiac systolic function were similar in the 2 groups, but the obese children had altered diastolic properties. The LV mass was greater in the obese children. No association was found between the lipid levels and the biophysical properties of the aorta. The relative oxygen consumption was 68% predicted in obese children. In conclusion, measures of the biophysical properties of the aorta are already abnormal in obese children, reflecting increased aortic stiffness at this early stage of disease. Obese children also had an increased LV mass, altered diastolic properties, and an abnormal exercise capacity. PWV might be useful in monitoring the progression of arterial disease or the effect of therapeutic interventions.
