Abstract ObjectiveThe study was aimed to evaluate the levels of NT-proBNP in mild, moderate and frequent ventricular ectopic burden in patients with preserved left ventricular function.Material and methodsA case control study was conducted in Islamic International Medical College (IIMC) in collaboration with Armed Forces Institute of Cardiology (AFIC) after approval from ethical review committee (ERC) of Riphah University (Ref #Riphah/IIMC/ERC/17/0230). It comprised of 120 Premature ventricular contractions (PVCs) patients with 40 patients in each group of mild (<10%), moderate (10-20%) and frequent (>20%) PVCs burden. 40 healthy subjects with no PVCs were taken as a control group. NT-proBNP levels were measured in all groups and statistical analysis was done by applying ANOVA and Pearson correlation tests to evaluate its association with PVCs burdenResultsNT-proBNP levels were found to be raised in all PVCs burden of <10%, 10-20% and >20% as compare to control group with p value of 0.039, 0.02 and 0.009 respectively. p value of ≤0.05 was considered significant. Symptomatic and asymptomatic patients show higher NT-proBNP levels as compared to control group with p-value of .002 and .04.Conclusion It is concluded that NT-proBNP levels are raised in patients of PVCs. This finding can be helpful for diagnostic purposes of PVCs.

Objective: In Vietnam, obesity is increasing particularly in many large cities. Adult cardiovascular diseases are often derived from cardiovascular disorders during the children period. The implementation of early measures to prevent atherosclerosis, such as weight control, better lipid control will reduce the cardiovascular complications, such as hypertension (HTA), coronary heart diseases and some other diseases. Materials and Methods: Overweight - obese children from 5 to 15 years old who visited the Children's Hospital in Can Tho from May 2009 to May 2010. Total number of patients were chosen as 50 children. Method: Descriptive cross-sectional. Children in the study underwent Doppler ultrasound exam to evaluate cardiac morphology and cardiac function. Results: There were increases in left ventricular systolic diameter, left ventricular diastolic diameter, LV mass in overweight-obese children in the study compared with controls at all ages (p <0.05 ). Left ventricular ejection fraction in overweight-obese children in the study was lower than the control group at all ages (p> 0.05). The average rate of left ventricular shortening of overweight-obese children in the study was 34.8 ± 4.5(%). There was no difference in the rate of shortening of the left ventricle in overweight-obese children in the study compared with controls (p>0.05). There was no relationship between variation in morphology and left ventricular function with the degree of overweight-obesity in this study. Conclusion: The study showed that disturbances in morphology and left ventricular function in overweight-obese children but did not find a strong association with the disorder degree of overweight-obesity.

AbstractBackground: In some inherited connective tissue diseases with involvement of the cardiovascular system, for example, Marfan syndrome, early impairment of left ventricular function, which have been described as Marfan-related cardiomyopathy has been reported. Our aim was to evaluate the left ventricular function in young adults with mitral valve prolapse without significant mitral regurgitation using two-dimensional strain imaging and to determine the possible role of the transforming growth factor-β pathway in its deterioration. Methods: We studied 78 young adults with mitral valve prolapse without mitral regurgitation in comparison with 80 sex-matched and age-matched healthy individuals. Longitudinal strain and strain rates were defined using spackle tracking. Concentrations of transforming growth factor-β1 and β2 in serum were determined by enzyme-linked immunosorbent assays. Results: In 29 patients, classic relapse was identified with a leaflet thickness of ≥ 5 mm; 49 patients had a non-classic mitral valve prolapse. Despite the similar global systolic function, a significant reduction in global strain was found in the classic group (−15.5 ± 2.9%) compared with the non-classic group (−18.7 ± 3.8; p = 0.0002) and the control group (−19.6 ± 3.4%; p < 0.0001). In young adults with non-classic prolapse, a reduction in longitudinal deformation was detected only in septal segments. Transforming growth factor-β1 and β2 serum levels were elevated in patients with classic prolapse as compared with the control group and the non-classic mitral valve prolapse group. Conclusions: These changes in the deformations may be the first signs of deterioration of the left ventricular function and the existence of primary cardiomyopathy in young adults with mitral valve prolapse, which may be caused by increased transforming growth factor-β signalling.

Cardiac complications are the most important cause of mortality and morbidity in Beta-Thalassemia Major (B-TM). The aim of our study was to determine the influence of Average Annual Mean Serum Ferritin (AAMSF) levels on cardiac function in patients suffering from B-TM. In this cross-sectional study, 50 patients of 5-15 years with B-TM were enrolled in the absence of clinical signs and symptoms of cardiac dysfunction. Left ventricular function was studied by using tissue Doppler image (TDI), pulse wave Doppler (PWD). AAMSF level was measured for 12 months. Patient groups were subdivided into two groups, group A with AAMSF level below 1000 ng/ml and group with B with AAMSF level above 1000 ng/ml. The Case group included 24(48%) males and 26(52%) females which were compared with 50 healthy subjects composed of 27(54%) males and 23 (46%) females (control group). The AAMSF Levels were 1054.60±687.95 ng/ml. By using PDW, in patients with AAMSF below 1000 ng/ml, The Parameters of the E, A, E/A E-DT had no significant difference with health groups (P=0.808, P=0.820, P=0.231 and P=0.061, respectively). No significant difference was revealed in parameters of E’, IVCT and ET in patients with AAMSF below 1000 ng/ml by using TDI in comparison to control (P=0.155, P=0.683, P=0.222, respectively).however, other TDI indexes including A’, E’/A’, IVRT, S,’ LVMPI, E/E’ had a significant difference with health group (P=0.014, P=0.041, P=0.045, P=0.002, P=0.021, and P=0.002, respectively). At patients with above AAMSF 1000 ng/mL, both PDW and TDI parameters had significant differences with the health group. There was no correlation among AAMSF levels and PWD or TDI indexes. The evidence from this study suggests that subclinical systolic and diastolic LV dysfunction has happened with AAMSF level above 1000 ng/ml, and according to our result, TDI is found more useful than PWD for subclinical cardiac evaluation.

Cardiomyopathy is the leading cause of increased mortality in diabetes. In the present study, we investigated the effects of decorin (DCN) gene therapy on left ventricular function, cardiac inflammation and fibrosis in type 2 diabetes. Type 2 diabetes was induced in male Wistar rats by high fat diet (HFD, 60% of calories as fat) and STZ (20 mg/kg, intraperitoneal). Diabetic rats were divided into (n=6 for each group) the control group, the GFP-treated group and the DCN-treated group, received intravenous injection of saline solution, recombinant adeno-associated viral (rAAV)-GFP, and rAAV-DCN, respectively. We evaluated cardiac inflammation, fibrosis, left ventricular function at 6 months after gene delivery. Results turned out that rAAV-DCN treatment attenuated diabetic cardiomyopathy with improved LV function compared with control animals, which might be related to the reduced cardiac inflammation and fibrosis. These protective effects were associated with TGFβ1 pathway (ERK1/2 and smad-2) and NF-κB pathway, which may due to the decreased activation level of IGF-IR, increased expression of PKC-α and Hsp70. In conclusion, our results show that rAAV-mediated DCN therapy may be beneficial in the treatment of Diabetic Cardiomyopathy.
