Echocardiography was employed to measure the serial effects of jogging on resting left ventricular dimensions and function. Twelve men were exercised (mean age 36.8 yr) and 10 served as controls (mean age 34.8 yr). Increases of 14 and 18% were observed for predicted aerobic capacity in the training group (TG) after 3 and 6 mo of training, respectively; the control group (CG) displayed a small detraining effect. Echocardiographic findings included a significant (P less than 0.05) reduction in resting heart rate and a moderate increase in stroke volume (SV) in the TG compared to the CG. The increased SV appeared to be due to increased end-diastolic dimensions (LVIDd, LVEDV), secondary to greater ventricular filling rather than a more vigorous ventricular contraction. Posterior wall thickness, septal thickness, and calculated left ventricular muscle mass were not significantly increased in the TG compared to CG after either 3 or 6 mo training. It was concluded that left ventricular structure and resting contractile status are not altered by 6 mo of jogging training in healthy, previously sedentary men.

Introduction: Left ventricular diastolic dysfunction (DD) is an entity in which the ventricle fails to fill up properly due to impaired ventricular relaxation and/or decreased compliance. The diagnosis of diastolic dysfunction is based on a variety of parameters in doppler echocardiograpy. However, some parameters like interventricular septal thickness in diastole (IVSd), posterior wall thickness in diastole (PWd), left ventricular internal end diastolic and systolic diameters (LVIDD and LVISD) along with left atrial diameters (LAD) have yet to be evaluated for the diagnostic workup of DD. Methods: A case control study was done in the cardiology department from patient records from 2016 to 2018. Patients were diagnosed as diastolic dysfunction grade II and above by doppler echocardiography. IVSd, PWd, LVIDD, LAD, LVISD were obtained through 2-D echocardiography. Results: Patients with DD had greater LAD, IVSd and PWd and decreased LVIDD and LVISD as compared to control group. Overall, IVSD was the most significant predictor (OR 1.52 95%CI 1.35-1.71) of DD followed by PWd and LAD. Similarly, LAD, IVSd and PWd had higher sensitivity and specificity than LVIDD and LVIDS. Conclusion: IVSd, LAD and PWd showed significant performance in the diagnosis of diastolic dysfunction and hence can be used as a screening and diagnostic tool in diastolic dysfunction of grade ll and above.

AbstractBackground:Previous studies have demonstrated structural changes in the heart and cardiac dysfunction in foetuses with intrauterine growth restriction. There are no available data that evaluated left ventricular dimensions and mass in neonates with symmetric and asymmetric intrauterine growth restriction. Therefore, we aimed to evaluate left ventricular dimensions, systolic functions, and mass in neonates with symmetric and asymmetric intrauterine growth restriction. We also assessed associated maternal risk factors, and compared results with healthy appropriate for gestational age neonates.Methods:In all, 62 asymmetric intrauterine growth restriction neonates, 39 symmetric intrauterine growth restriction neonates, and 50 healthy appropriate for gestational age neonates were evaluated by transthoracic echocardiography.Results:The asymmetric intrauterine growth restriction group had significantly lower left ventricular end-systolic and end-diastolic diameters and posterior wall diameter in systole and diastole than the control group. The symmetric intrauterine growth restriction group had significantly lower left ventricular end-diastolic diameter than the control group. All left ventricular dimensions were lower in the asymmetric intrauterine growth restriction neonates compared with symmetric intrauterine growth restriction neonates (p>0.05), but not statistically significant except left ventricular posterior wall diameter in diastole (3.08±0.83 mm versus 3.54 ±0.72 mm) (p<0.05). Both symmetric and asymmetric intrauterine growth restriction groups had significantly lower relative posterior wall thickness (0.54±0.19 versus 0.48±0.13 versus 0.8±0.12), left ventricular mass (9.8±4.3 g versus 8.9±3.4 g versus 22.2±5.7 g), and left ventricular mass index (63.6±29.1 g/m2versus 54.5±24.4 g/m2versus 109±28.8 g/m2) when compared with the control group.Conclusions:Our study has demonstrated that although neonates with both symmetric and asymmetric intrauterine growth restriction had lower left ventricular dimensions, relative posterior wall thickness, left ventricular mass, and mass index when compared with appropriate for gestational age neonates, left ventricular systolic functions were found to be preserved. In our study, low socio-economic level, short maternal stature, and low maternal weight were found to be risk factors to develop intrauterine growth restriction. To our knowledge, our study is the first to evaluate left ventricular dimensions, wall thicknesses, mass, and systolic functions in neonates with intrauterine growth restriction and compare results with respect to asymmetric or symmetric subgroups.

AbstractDilated cardiomyopathy (DCM) is the third leading cause of heart failure in pediatrics. The exact etiology of DCM is unknown in more than half of the cases. Vitamin D receptors are represented in cardiac muscles, endothelium, and smooth muscles of blood vessels suggesting that vitamin D could have a vital cardioprotective function. This study aimed to assess serum level of vitamin D in children with idiopathic DCM and to correlate the serum level of vitamin D with the left ventricular dimensions and function. This study is a descriptive cross-sectional single-center study, includes 44 children of both sexes, diagnosed as idiopathic DCM. Serum level of vitamin D was assessed and correlated with the left ventricular dimensions and function. Mean age of studied children was 6.08 ± 4.4 years. Vitamin D deficiency was found in 90.9% of children with idiopathic DCM with a mean level 13.48 ng/mL. There was a negative correlation between vitamin D level and fraction shortening and left ventricular end-diastolic diameter in children with DCM. Vitamin D level is not only significantly low in children with idiopathic DCM but it is also significantly correlated with the degree of left ventricular dysfunction.

We hypothesized that cardiac dysfunction was responsible for the high perinatal lethality that we previously reported in fibrinogen-like protein 2 ( Fgl2) knockout (KO) mice. We therefore used ultrasound biomicroscopy to assess left ventricular (LV) cardiac structure and function during development in Fgl2 KO and wild-type (WT) mice. The only deaths observed between embryonic day (E)8.5 (onset of heart beating) and postnatal day (P)28 (weaning) were within 3 days after birth, when 33% of Fgl2 KO pups died. Histopathology and Doppler assessments suggested that death was due to acute congestive cardiac failure without evidence of valvular or other obvious cardiac structural abnormalities. Heart rates in Fgl2 KO embryos were significantly reduced at E8.5 and E17.5, and irregular heart rhythms were significantly more common in Fgl2 KO (21/26) than WT (2/21) embryos at E13.5. Indexes of systolic and/or diastolic cardiac function were also abnormal in KO mice at E13.5 and E17.5, in postnatal mice studied at P1, and in KO mice surviving to P28. M-mode analysis showed no difference in LV diastolic chamber dimension, although posterior wall thickness was thinner at P7 and P28 in Fgl2 KO mice. We conclude that Fgl2 deficiency is not associated with obvious structural cardiac defects but is associated with a high incidence of neonatal death as well as contractile dysfunction and rhythm abnormalities during embryonic and postnatal development in mice.

The aim of this study was to evaluate clinical and echocardiographic characteristics of patients with diabetic cardiomyopathy. The study included 72 patients, divided into two groups. The experimental group consisted of 32 diabetics, while 40 gender and age-matched healthy subjects were in the control group. In the experimental group there were 17 patients with insulin-dependent diabetes mellitus, and 15 patients with non-insulin-dependent diabetes mellitus. The average duration of diabetes mellitus was 9.53 years. All the patients underwent the following diagnostic procedures: standard laboratory tests, 12-lead ECG, chest X-ray, 24-h Holter ECG, and complete echocardiographic examination. More frequent appearance of ventricular rhythm disturbances (65,6% vs. 47,5%), increased heart rate (78.3 ? 8.2 vs. 72.1 ? 4.6 beats per minute), and alteration of diastolic (56.25% vs. 12.5%) and systolic function (43.8% vs. 0%) was registered in patients with diabetes, compared to the control group. Experimental group was divided, according to their left ventricular dimensions, into two subgroups: the subgroup with normal left ventricular dimensions, and the subgroup with the increased left ventricular dimensions. Patients with the increased left ventricular dimensions not only had significantly lower ejection fraction (37.4 ? 7.0 vs. 61.3 ? 4.2%), but also had significantly longer duration of diabetes (12.6 ? 5.8 vs. 8.01 ? 3.01 years), worse quality of glycoregulation (13.1 ? 2.5 vs. 10.4 ? 2.1%), and higher Shapiro?s microvascular complications index (2.7 ? 1.26 vs. 0.68 ? 0.56). High degree of correlation was also found between the duration of diabetes left ventricular ejection fraction (-0.86), and left ventricular mass (0.86). The similar level of correlation was shown with Shapiro?s index (-0.77 and 0.88), as well as with morning glycaemia (-0.57 and 0.41). According to the obtained results it could be concluded that the changing rate of diabetic cardiomyopathy was in direct correlation with the quality of diabetes control, the duration of diabetes, and the presence of complications in other organs.
