Background: Diabetic patients with normal left ventricular ejection fraction (LVEF)are frequently associated with diastolic dysfunction. However, LVEF is known not to be a sensitive marker for the detection of subclinical LV systolic dysfunction. This study aimed to assess left ventricular systolic and diastolic function in asymptomatic type 1 diabetic patients by conventional, tissue Doppler and two-dimensional speckle tracking echocardiography to assess subclinical left ventricular systolic and diastolic dysfunction. Methods: Case-control study was conducted at 150 patients aged 15-35 y were subdivided into three equal groups: Group A: with type 1 diabetes mellitus (T1DM) with good metabolic control (Hb A1C <7.0), Group B: T1DM with poor metabolic control (Hb A1C>7.0), and Group C: Control group: included 50 normal healthy subjects. Results: Tissue Doppler, diastolic function and strain parameters, AP4C LS, AP2C LS, AP3C LS, and GLS were significantly impaired among the three groups. AP4C LS, AP2C LS, AP3C LS, and GLS were significantly lower in group B than group A and group C and was significantly lower in group A than group C, A velocity was significantly impaired among the three groups. A velocity was significantly higher in group B than group A and group C and was insignificantly impaired in group A than group C. Conclusion: Conventional echocardiography parameters were insignificantly different between the study groups. 2D speckle tracking and tissue Doppler echocardiography showed that subclinical left ventricular systolic function may be affected even before affection of diastolic function. Longer duration and poor glycemic control of diabetes significantly affect GLS.

OBJECTIVE: To determine which of two simplified blood glucose monitoring schemes promotes better metabolic control in type1 diabetic patients during 12 months of participation in educational groups. METHODS: A crossover clinical trial involving 21 patients divided into two groups was conducted. They were submitted to a two monitoring schemes:2 alternate daily preprandial measurements and 2 alternate daily pre-and postprandial measurements. The effectiveness of the schemes was evaluated based on HbA1c. Variations in mean HbA1c were analyzed by Friedman test. RESULTS: The groups were homogenous in terms of sociodemographic and clinical variables (p>0.05). Mean HbA1c levels ranged from 8.48 (±1.00) to 7.37 (±0.99) over time in Group A and from 9.89 (±0.86) to 8.34 (±1.06) in Group B. The analysis of the HbA1c showed a significant reduction in the first and last 6 months and over the 12 months of the study in two groups (p<0.05). The preprandial scheme demonstrated the largest number and highest percentage of significant drops in HbA1c. CONCLUSIONS: The two monitoring improved the metabolic control and the preprandial scheme was more effective.

Aim — to compare the features of diastolic dysfunction (DD) with preserved left ventricular (LV) ejection fraction (EF) in patients with diabetes mellitus type 2 (DM2) with arterial hypertension (AH) and in patients with essential hypertension (EH) without diabetes.Material and methods. The study involved 87 patients with DD with preserved LV EF: 53 patients with DM2 with AH and 34 patients EH without diabetes. Transthoracic echocardiography was performed by ultrasonic imaging system iE33 xMATRIX («Philips», USA). DD was determined in a complex: type on the basis of the ratio parameters of pulsed-wave (E/A) and tissue (e/a) Doppler; and severity on the Е/e values and pulmonary capillary wedge pressure (PCWP). Myocardial contractile function was assessed by traditional LVEF by Simpson and more exactly, in details on the basis of the longitudinal, radial and circular deformation of the LV myocardium by speckle-tracking echocardiography (using the program Q-lab 3.0 Advanced Ultrasound Quantification software).Results. The groups were comparable in clinical characteristics. The average level of HbA1c in patients with DM2 was 8.2±1.7%. The average LV EF by Simpson in the EH group was 59.9±8.1, in DM2 — 58.3±6.7 (p=0.228). There were more severe disorders of LV Diastolic function in DM2 patients: the values of E/e (p=0.000) and PCWP (p=0.001) were significantly higher in diabetic patients (14,1±5,5 and 15,3±4,7 mm Hg) than in EH (9.7±2.3 and 11.9±1.3 mm Hg). Although that the LV EF (by traditional echocardiographic method of Simpson) was preserved in both groups , the LV global longitudinal strain (12.4±3.0) was significantly lower in DM2 (p=0.005), than patients with EH (16.6±2.0) by speckle-tracking echocardiography.Conclusion. Severity of LV DD are harder in Patients with diabetes and hypertension, than in patients with EH with the similarity of clinical manifestations and data of traditional echocardiographic methods. There were found initial disorders of LV longitudinal myocardial fibers contraction by speckle-tracking echocardiography in patients with DM and preserved LV EF. The combination of impairment of systolic and diastolic function in diabetes is inseparable. Early development of combined systolic and diastolic dysfunction in DM2 is associated with a poor prognosis: a higher risk of early development of atrial fibrillation, ventricular arrhythmias and progressive heart failure.

Abstract Background Malnourished children endure many changes in body composition and lose heart and skeletal muscle mass. Diastolic dysfunction is one of the major causes of heart failure with preserved ejection fraction. Aim To assess left ventricular systolic and diastolic functions in children with severe acute malnutrition using tissue Doppler imaging technique and to evaluate the effect of nutritional rehabilitation. Patients and Methods A follow-up case-control study conducted on 60 severely malnourished children (WHZ < -3SD) and 120 age and sex-matched healthy children as a control group. Tissue Doppler imaging (TDI) was done for all included malnourished children at admission and for control to measure left ventricular systolic and diastolic functions. Nutritional rehabilitation was done according to WHO protocol and tissue doppler was repeated after rehabilitation when (WHZ > -2SD) to detect any changes in systolic or diastolic functions. Results Systolic function was normal in malnourished children and control. Grade I diastolic dysfunction was detected in 40% and grade II in 30% of severely malnourished children in comparison to 100% normal diastolic function in control group. No correlations between diastolic dysfunction and either anthropometric measurements, electrolyte disturbances or Hb% in malnourished children before nutritional rehabilitation. Mortality from sepsis with associated ventricular dysfunction grade II documented in 3.3% of malnourished children. After nutritional rehabilitation diastolic function improved significantly as 65.6% of children attained normal diastolic function, 31% grade1 and 3.4% grade II. Positive correlations between diastolic function and WAZ, HAZ, WHZ and MUAC after rehabilitation. Conclusion Severe acute malnutrition affects diastolic function in children which is reversible in most of these cases with rehabilitation. TDI is an easy and practical method for detection and follow-up of ventricular function in malnourished children.

Abstract The involvement of diabetes in the occurrence of an alteration of the diastolic function of LV is well established. The objective of our study was to evaluate the prevalence of diastolic dysfunction in Type II diabetic patients in light of the latest 2016 recommendations of the American Society of Echocardiography and to identify its associated factors. It was a cross-sectional observational study with a descriptive and analytic focus spread over a 6-month period from July to December 2017.The study included 66 asymptomatic type II diabetic patients, with a normal ECG and a negative stress test ischemia. All hypertensive subjects with an ejection fraction &lt;50%, or those with myocardial, valvular or rhythm disorder, were excluded. The mean age of our patients, was 42 years ± 9 years with extremes ranging from 39 to 84 years, we noted a female predominance (68%) with a sex ratio of 2.14. The prevalence of diastolic dysfunction was 27%. Factors associated with this change in diastolic function were advanced age (p &lt;0.0001), age of diabetes&gt; 10 years (p &lt;0.0001), glycemic imbalance with HbA1c&gt; 7% (p &lt;0) , 0001) and elevated fasting glucose levels (p = 0.039), obesity (p &lt;0.0001), dyslipidemia (p &lt;0.0001) and menopause (p = 0.002). Diastolic dysfunction affects a significant percentage of patients with type II diabetes. Therefore, we propose strict glycemic control in these patients, an early cardiographic echo screening in at-risk subjects, in order to improve their management, and to limit their progression to more serious complications.

Abstract Recently, several studies have demonstrated that tumor necrosis factor microsatellite polymorphism (TNFa) contributes to the susceptibility of type 1 diabetes. This study investigates the influence of TNFa on the predisposition to insulin dependency in adult-onset diabetic patients with type 1 diabetes-protective human leukocyte antigen haplotypes. The TNFa of three groups of DRB1∗1502-DQB1∗0601-positive diabetic patients who had initially been nonketotic and noninsulin dependent for more than 1 yr was analyzed. Group A included 11 antibodies to glutamic acid decarboxylase (GADab)-positive patients who developed insulin dependency within 4 yr of diabetes onset. Group B included 11 GADab-positive patients who remained noninsulin dependent for more than 12 yr. Group C included 12 GADab-negative type 2 diabetes, and a control group included 18 nondiabetic subjects. In the group C and control subjects, DRB1∗1502-DQB1∗0601 was strongly associated with the TNFa13 allele. DRB1∗1502-DQB1∗0601 was strongly associated with the TNFa12 allele among the group A patients, but not among the group B patients. Interestingly, sera from all patients with non-TNFa12 and non-TNFa13 in group B reacted with GAD65 protein by Western blot. These results suggest that TNFa is associated with a predisposition to progression to insulin dependency in GADab/DRB1∗1502-DQB1∗0601-positive diabetic patients initially diagnosed with type 2 diabetes and that determination of these patients’ TNFa genotype may allow for better prediction of their clinical course.

SIGNIFICANCE OF THE PROBLEM: The diagnosis of acute viral myocarditis is one of the diagnoses most difficult to make in cardiology and medicine in general. Echocardiography and cardiomagnetic resonance play a crucial role in the clinical diagnosis and the serum titer of antiviral antibodies to cardiotropic viruses is still unjustifiably used for the diagnosis of myocarditis in everyday practice. RESEARCH OBJECTIVES: To analyze the frequency and significance of echocardiographic parameters in the diagnosis of clinically suspected acute viral myocarditis, to determine the role of antiviral antibody titer (AVA) dynamics for the diagnosis of myocarditis and to compare viral serology and echocardiographic function versus echocardiographic function. METHODOLOGY: A retrograde transverse study was performed in the ten-year period from 2006. to 2015, where 126 consecutive patients from the database of the Office of Internal medicine ''Dr. Bastać'' were analyzed, with a working diagnosis of clinically suspected viral myocarditis. They were clinically, ECG, echocardiographically and serologically monitored for 4 to 8 weeks due to the dynamics of AVA titer. The examined group (A) was divided into subgroups: A1 with elevated AVA class IgM titer in 43 (32%) subjects and subgroup A2 without elevated IgM titer in 83 (68%) patients. The control group of healthy (B) of 103 subjects was comparable.Statistical processing was done in the EXCELL database via descriptive statistics, Student's-T test and Chi2 test. RESULTS: 126 patients had clinically suspected myocarditis (≥2 ESC criteria). Diastolic left ventricular dysfunction in 39/126 (31%) patients was the dominant echocardiographic criterion for clinically suspected myocarditis. Reduced ejection fraction (EF <50%) was measured at 19/126 (15%), followed by left ventricular dilatation. Regional systolic dysfunction was found in 21/126 (17%) and changes in myocardial texture in 17 (13%) subjects. The clinical probability of viral etiology was diagnostically supported by elevated titer of IgM antibodies in 43 (32%) subjects (subgroup A1) where IgM antibodies to Parvo B 19 virus predominate in 36/43 patients (84%). Most were without elevated titer of IgM antibodysubgroup A2 83 (68%). Clear dynamics of IgM antibody titer was observed in 23 persons, a decrease in IgM titer with an increase in IgG titer (seroconversion) in 13 patients. Determination of anti-heart autoantibodies (AHA) was done in 17 severe cases, of which 9 had positive AHA. A comparison of subgroups A1 and A2 did not reveal a statistically significant difference in echocardiographic parameters. The whole group A of clinically suspected myocarditis compared to control group B has statistically highly significantly lower parameters of global systolic (EF=8,7±4,6 vs. 63±7,9; p<0,001), longitudinal systolic (S'=6,9±1,3 vs. 9,9±2,1) and diastolic function (E/e'11,9±4,8 vs. 8,7±4,6; p<0,001), and a highly statistically significant increase in left ventricular telediastolic dimension, myocardial mass index, and left atrial size. CONCLUSION: The diagnosis of acute viral myocarditis in clinical practice is made on the basis of the clinical picture, ECG and echocardiography that indicate myocarditis with the exclusion of cardiac comorbidities, based on the ESC criteria for suspected clinical myocarditis. The whole group A had highly statistically significantly lower parameters of systolic and diastolic function compared to control group B. Normal ECG and echocardiography cannot serve to exclude the diagnosis of myocarditis. Comparison of subgroups A1 and A2 did not reveal a statistically significant difference in echocardiographic parameters.
