Abstract Background and Aims The structure and function of the left ventricle (LV) are affected since the early stages of chronic kidney disease (CKD). Our cross-sectional study aimed to estimate the echocardiographic indices of the LV diastolic function and the evaluation of their potential correlation with indices of kidney injury in patients with CKD, before initiation of renal replacement therapy. Method 99 patients with CKD (stage 2 CKD: 31 patients (27%), stage 3 CKD: 47 patients (40.9%) and stage 4 CKD: 37 patients (32.1%)) were enrolled in the study. Anthropometric data, indices of renal function (eGFR-CKD-EPI, urinary protein excretion in mg/24h), biochemical laboratory parameters, comorbidities [hypertension (HT), diabetes mellitus (DM), coronary heart disease (CAD)] and echocardiographic indices of LV diastolic function were recorded. In specific, left atrial (LA) dimensions were measured in M-Mode and were expressed both as absolute values in mm as well as indexed to body surface area ((BSA) and expressed as the LA index in mm/m2. The study sample, after taking into account patient gender, was further divided into separate groups according to the presence or not of LA dilation. Results The average patient age was 62 +/- 13 years and average eGFR (CKD-EPI) was 44.1+/-21.4 ml/min/1.73m2. With regard to comorbidities, 59.3% of the sample population had arterial hypertension, 24.3% had diabetes mellitus and 10.4% had known coronary artery disease. Regarding anti-hypertensive and hypolipidemic treatment, 22.6% of the patients were on ARB and 24% on ACEi, 51.3% on CCB, 29.6% on β-blockers, 37.4% on diuretics and 28.7% of the patients were receiving statin treatment. 28.2% of the patients had dilated LA in terms of absolute value and 13.8% had dilated LA following indexing to BSA (LA index). A positive correlation was observed between the LA size and age (p=0.001), BMI (p=0.041), uric acid levels (p=0.022), PTH (p=0.029), fibrinogen (p=0.035), LV mass (p=0.006) and LV mass/BSA (p=0.005), whereas a negative correlation was observed with serum LDL (p=0.027). Additionally, there was observed a negative correlation of LA index with eGFR (p=0.05), as well as an inverse relationship between LA index and PTH (p=0.012), age (p=0.004), BMI (p=0.037) and LV mass/BSA (p=0.005). No significant correlations between LA size and LA index with proteinuria or with co-morbidities (DM, HT, CAD) were observed. Conclusion In a population of patients with stage 2-4 CKD, LA size correlated to indices of CKD. Larger studies are required in order to further confirm these correlations.

his study was designed to characterize left ventricular (LV) function and mass in a modified cardiomyopathy model in the dog in which right ventricular pacing rates are gradually increased throughout 38 days. On the last day of the pacing protocol, ejection fraction was reduced (25 +/- 3 vs. 60 +/- 1%) and LV end-diastolic diameter index (a ratio of LV end-diastolic diameter to body weight, 2.09 +/- 0.02 vs. 1.79 +/- 0.08 mm/kg) and LV mass index (a ratio of LV mass to body weight, 5.2 +/- 0.3 vs. 4.3 +/- 0.2 g/kg) were greater than in the normal dogs (P < 0.05, respectively). Cardiac filling pressures increased, and LV diastolic function and coronary blood flow were impaired. After 4 wk of recovery from the progressive pacing protocol, LV end-diastolic diameter index (2.12 +/- 0.06 mm/kg) and LV mass index (5.6 +/- 0.2 g/kg) remained increased. Ejection fraction was improved (38 +/- 4%) but still depressed. LV diastolic function, coronary blood flow, and cardiac filling pressures returned to levels seen in the normal dogs. This modified cardiomyopathy model associated with LV hypertrophy complements the conventional tachycardia-induced cardiomyopathy model without LV hypertrophy.

Abstract Background Left ventricular (LV) diastolic dysfunction can be a sole cause of all-cause mortality, while increased epicardial fat thickness (EFT) is significantly correlated with impairment of LV diastolic function. Herein, we examined the relationship between EFT measured by echocardiography and LV diastolic function in a Beijing community population.Methods We included 1004 participants in this study. Echocardiographic parameters including E and A peak velocity, the early diastolic velocities (e’) of the septal and lateral of mitral annulus using tissue doppler imaging, E/e’, and EFT, were measured. EFT1 was measured perpendicularly on the right ventricular free wall at end-diastole in the extension line of the aortic root. EFT2 was the maximum thickness measured perpendicularly on the right ventricular free wall at end-diastole. Multivariate linear regression was used to analyze the relationship between EFT and the mean e’ and E/e’.Results The mean age of the participants was 63.91 ± 9.02 years old (51.4% men). EFT1 and EFT2 were negatively correlated with e’ lat, e’ sep, and e’ mean (p < 0.05), and positively correlated with E/e’ lat, E/e’ sep, and E/e’ mean. Multivariate regression analysis showed that EFT1 and EFT2 were independently and negatively correlated with e’ mean (EFT1: β = −0.089 [95% confidence interval = −0.177, −0.000, p = 0.050]; EFT2: β = −0.078 [95% confidence interval = −0.143, −0.012, p = 0.020]). There were no interactions between EFT and any covariates, including age or heart groups, sex, BMI, or presence of hypertension, diabetes, or coronary heart disease in relation to LV diastolic dysfunction.Conclusions EFT was negatively and independently correlated with e’ mean, suggesting that more attention to this type of adipose fat is required for cardiovascular disease therapy.

Aim: Hypertension is associated with cardiac structural and functional changes, including left ventricular hypertrophy (LVH) and LV systolic dysfunction diastolic dysfunction. Neutrophil-to-lymphocyte ratio (NLR) is a novel inflammatory biomarker associated with cardiovascular diseases. The current study aimed to evaluate NLR in children with newly diagnosed essential hypertension and its relationship between blood pressure and cardiac changes.Methods and Subjects: Sixty-five children with newly diagnosed essential hypertension and 54 healthy children were included. Clinical characteristics, blood cell counts, and biochemical parameters were collected. LVH was assessed by calculation of LV mass index (LVMI), and LV systolic function was evaluated by measuring LV ejection fraction and fractional shortening. LV diastolic function was primarily assessed with E/E′ ratio by Doppler and echocardiography.Results: The hypertension children had significantly higher LVMI and E/E′ ratio than the controls, whereas there was no difference in LV systolic function between the two groups. The NLR was significantly higher in the hypertension group than the control group. Moreover, NLR was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels in the hypertension group. Additionally, a significantly positive correlation between NLR and E/E′ ratio was found in the hypertension group. However, NLR was not related to LVH and LV systolic function indicators in hypertension children.Conclusion: NLR is elevated in hypertension children, and it is associated positively with office blood pressure levels. Moreover, NLR may help assess LV diastolic function in hypertension children.

Abstract Introduction Cardiac involvement in Systemic Lupus Erythematosus (SLE) may lead to left ventricular (LV) hypertrophy with possible impairment of LV diastolic function and left atrial (LA) function, particularly in patients with severe forms of SLE with neuropsychiatric manifestations (NPSLE) and can also be associated with cardiovascular outcome. Purpose We evaluated the prevalence of LV diastolic dysfunction and LA dysfunction in a large cohort of SLE patients including also NPSLE patients, and their association with the occurrence of cardiovascular events (cerebrovascular accidents, lung-embolism, coronary revascularisation, heart failure hospitalisations and development of supraventricular arrhythmias). Methods A total of 102 SLE patients (87% female, 42±15 years) were included, of which 43 (42%) with NPSLE according to a multidisciplinary team assessment. All patients fulfilled the American College of Rheumatology (ACR 1997) and Systemic Lupus Erythematosus International Collaborating Clinics (SLICC 2012) classification criteria for SLE. Echocardiography was performed at the first visit: LV diastolic function was assessed according to current recommendations and including Tissue Doppler Imaging measures; LA volume (LAVI) was also measured and LA function was assessed by LA reservoir strain using 2D speckle tracking imaging. Results In the SLE patients, mean LV mass index was 82±32 g/m2, 29% of patients showed an e'septal <10, 7% an E/e'>14, 16% a LAVI>34 ml/m2 and 5% a tricuspid velocity >2.8m/s. When applying the currently recommended multiparametric approach, only 4% of SLE patients showed LV diastolic dysfunction. In NPSLE patients, the prevalence of LV diastolic dysfunction was not significantly higher (5%). However, an impaired LA reservoir strain (based on the median value of 25%) was observed in 54% of the total SLE population and in 77% of NPSLE patients suggesting higher sensitivity of this parameter to detect impaired LA function and LV diastolic function. During a median follow up of 11 years (Interquartile range: 4–19 years), 43 (42%) patients developed a cardiovascular event. Kaplan-Meier curve analysis showed that SLE patients with impaired LA strain <25% experienced higher cumulative rates of cardiovascular events, as compared to SLE patients with LA strain≥25% (Chi-square 4.350; Log rank p=0.037). At the uni- and multivariate Cox-regression models, LA strain showed significant association with cardiovascular events (hazard ratio [HR]:0.944; 95% confidence interval [CI]: 0.893–0.997; p=0.039) together with age (HR: 1.030; 95% CI: 1.002–1.059; p=0.039) after correcting for LV mass index and LV diastolic dysfunction. LA reservoir strain Conclusions LA dysfunction as assessed by LA reservoir strain is significantly impaired in SLE and particularly in NPSLE patients and improve detection of myocardial involvement in these patients. Furthermore, LA reservoir strain is independently associated with the development of cardiovascular events.

Aims: Eastern Finns have higher risk of coronary heart disease (CHD) and carotid intima-media thickness than western Finns although current differences in CHD risk factors are minimal. Left ventricular (LV) mass and diastolic function predict future cardiovascular events but their east–west differences are unknown. We examined the association of eastern/western baseline origin with LV mass and diastolic function. Methods : The study population included 2045 subjects of the Cardiovascular Risk in Young Finns Study with data from the baseline survey (1980) and the latest follow-up (2011) when echocardiography was performed at the age of 34–49 years. Results: Subjects with eastern baseline origin had in 2011 higher LV mass (139±1.0 vs. 135±1.0 g, p=0.006) and E/e′-ratio indicating weaker LV diastolic function (4.86±0.03 vs. 4.74±0.03, p=0.02) than western subjects. Results were independent of age, sex, area of examination and CHD risk factors such as blood pressure and BMI (LV mass indexed with height: p<0.0001; E/e′-ratio: p=0.01). LV end-diastolic volume was higher among subjects with eastern baseline origin (135±0.9 vs. 131±0.9 ml, p=0.0011) but left atrial end-systolic volume, also indicating LV diastolic function, was not different between eastern and western subjects (43.4±0.5 vs. 44.0±0.5 ml, p=0.45). Most of the subjects were well within the normal limits of these echocardiographic measurements. Conclusions: In our healthy middle-aged population, geographic origin in eastern Finland associated with higher LV mass compared to western Finland. Higher E/e′-ratio suggests that subjects with eastern baseline origin might have higher prevalence of diastolic dysfunction in the future than western subjects.

1. Left ventricular (LV) diastolic function was investigated in three different age groups (15, 28 and 50 weeks) of paired spontaneously hypertensive (SHR) and normotensive (WKY) rats under pentobarbital anaesthesia. A time constant of LV pressure decay, represented by T, was used as an index of LV relaxation. We assessed the relationship between haemodynamic parameters and LV structural components as quantified by microspectrophotometry (MSP), using multivariate analysis. 2. T was significantly prolonged in the 28 and 50 week old SHR compared with their normotensive counterparts (P < 0.05 and P < 0.01, respectively). T was prolonged by volume loading but was not affected with afterload elevation by angiotensin infusion in all age groups of the SHR and WKY. 3. LV wall thickness was greater in the SHR at all ages and was positively correlated with T (r = 0.42, P < 0.05). 4. A significant correlation was found between the increase in cardiac muscle fibre and collagen, the decrease in elastin and glycoprotein, and T on multivariate analysis (r = 0.53, P < 0.05). 5. We conclude that LV relaxation of SHR is disturbed from a relatively young age (28 weeks), for which we consider myocardial hypertrophy and LV structural changes found by MSP as being responsible.

Background:Appearance of microalbuminuria, particularly in patients with hypertension, might be associated with a higher prevalence of left ventricular (LV) dysfunction and geometric abnormalities. This study was undertaken to determine whether high urine albumin to creatinine ratio (UACR) as a sensitive marker for microalbuminuria can be associated with LV hypertrophy (LVH) and systolic and diastolic LV dysfunction.Methods:The study population consisted of 125 consecutive patients with essential uncomplicated hypertension. Urine albumin and creatinine concentration was determined by standard methods. LVH was defined as a LV mass index >100 g/m2 of body surface area in women and >130 g/m2 in men. Echocardiographic LV systolic and diastolic parameters were measured.Results:The prevalence of microalbuminuria in patients with essential hypertension was 5.6 %. UACR was significantly no different in patients with LVH than in patients with normal LV geometry (21.26 ± 31.55 versus 17.80 ± 24.52 mg/mmol). No significant correlation was found between UACR measurement and systolic and diastolic function parameters, including early to late diastolic peak velocity (E/A) ratio (R=-0.192, p=0.038), early diastolic peak velocity to early mitral annulus velocity (E/E') ratio (R=-0.025, p=0.794), LV ejection fraction (R=0.008, p=0.929), and LV mass (R=-0.132, p=0.154). According to the receiver operator characteristic (ROC) curve analysis, UACR measurement was not an acceptable indicator of LVH with areas under the ROC curves 0.514 (95 % confidence interval 0.394–0.634). The optimal cut-off value for UACR for predicting LVH was identified at 9.4, yielding a sensitivity of 51.6 % and a specificity of 48.3 %.Conclusion:In patients with uncomplicated essential hypertension, abnormal systolic and diastolic LV function and geometry cannot be effectively predicted by the appearance of microalbuminuria.
