Background: Cardiac remodeling is important issue after surgical closure of ventricular septal defect.Objective: The purpose of the present study was to evaluate cardiac remodeling by echocardiography by measuring the ejection fraction, fractional shortening, left ventricular internal diameter during diastole (LVIDd) and left ventricular internal diameter during systole (LVIDs) after surgical closure of ventricular septal defect in different age group. Methodology: This prospective cohort studies was conducted in the Department of Cardiac Surgery at National Institute of Cardiovascular Disease (NICVD), Dhaka. Patient with surgical closure of VSD were enrolled into this study purposively and were divided into 3 groups according to the age. In group A (n=10), patients were within the age group of 2.0 to 6.0 years; age of group B (n=8) patients were 6.1-18.0 years and the group C (n=6) aged range was 18.1-42.0 years. Echocardiographic variables such as ejection fraction, fractional shortening, LVIDd, LVIDs were taken preoperatively and at 1st and 3rd month of postoperative values. Result: A total number of 24 patients was recruited for this study. The mean ages of all groups were 12.60±12.09. After 1 month ejection fraction were decreased by 5.97%, 6.71% and 5.66% in group A, group B and group C respectively. After 3 months ejection fraction were increased by 6.13%, 5.13% and 5.14% in group A, group B and group C respectively. After 1 month fractional shortening were decreased by 13.55%, 9.30% and 9.09% in group A, group B and group C respectively. After 3 months fractional shortening were increased by 7.23%, 7.35% and 4.55% in group A, group B and group C respectively. After 1 month LVIDd were increased by 1.97%, 1.91% and 1.32% in group A, group B and group C respectively. After 3 months LVIDd were decreased by 10.84%, 9.89% and 7.34% in group A, group B and group C respectively. After 1 month LVIDs were increased by 2.19%, 2.86% and 1.98% in group A, group B and group C respectively. After 3 months LVIDs were decreased by 11.68%, 10.97% and 8.87% in group A, group B and group C respectively.Conclusion: Cardiac remodeling occurred after surgical closure of ventricular septal defect and remodeling were more significant in younger age group.

Purpose. Myocardial regeneration is one of the most ambitious goals in prevention of adverse cardiac remodeling. Macrophages play a key role in transition from inflammatory to regenerative phase during wound healing following myocardial infarction (MI). We have accumulated data on macrophage properties ex vivo and in cell culture. However, there is no clear information about phenotypic heterogeneity of cardiac macrophages in patients with MI. The purpose of the project was to assess cardiac macrophage infiltration during wound healing following myocardial infarction in clinical settings taking into consideration experimental knowledge.Material and Methods. The study included 41 patients with fatal MI type 1. In addition to routine analysis, macrophages infiltration was assessed by immunohistochemistry. We used CD68 as a marker for the cells of the macrophage lineage, while CD163, CD206, and stabilin-1 were considered as M2 macrophage biomarkers. Nine patients who died from noncardiovascular causes comprised the control group.Results. The intensity of cardiac macrophage infiltration was higher during the regenerative phase than during the inflammatory phase. Results of immunohistochemical analysis demonstrated the presence of phenotypic heterogeneity of cardiac macrophages in patients with MI. We noticed that numbers of CD68+, CD163+, CD206+, and stabilin-1+ macrophages depended on MI phase.Conclusion. Our study supports prospects for implementation of macrophage phenotyping in clinic practice. Improved understanding of phenotypic heterogeneity might become the basis of a method to predict adverse cardiac remodeling and the first step in developing myocardial regeneration target therapy.

BACKGROUND. Increased salt intake is associated with a number of cardiovascular events, including increased blood pressure (BP) and the development of left ventricular hypertrophy (LVH). However, there is much evidence that a high content of sodium chloride in the diet does not always lead to an increase in BP, but almost inevitably causes cardiac remodeling, in particular, LVH. Many aspects of myocardial remodeling induced by high sodium content in the food have not been studied enough. THE AIM of the study was to trace the echocardiographic changes in Wistar rats fed the high salt ration and the high salt ration supplemented with soy proteins.MATERIAL AND METHODS. Echocardiography and BP measurements were performed on male Wistar rats, divided into three groups. The first (control; n = 8) included rats that received standard laboratory feed (20.16 % animal protein and 0.34 % NaCl); the second (n = 10) – animals that received standard feed and 8 % NaCl (high salt ration). The third group (n = 10) consisted of rats who consumed a low-protein diet containing 10 % soy protein isolate (SUPRO 760) and 8 % NaCl. The follow-up period was 2 and 4 months.THE RESULTS of the study showed that: (1) the intake of a large amount of salt with a diet does not necessarily lead to the formation of arterial hypertension; (2) despite the absence of a distinct increase in BP, under these conditions signs of cardiac remodeling, in particular, LVH, appear rather quickly; (3) supplementing a high-salt diet with soy isolates counteracts the development of LVH.CONCLUSION. High salt intake with food can cause heart remodeling, regardless of blood pressure, while soy proteins can counteract this process.
