The aim of this study was to assess echocardiographic changes in female patients with untreated dysfunctional thyroid states and whether the therapy aimed to normalize the thyroid dysfunction could lead to improvement in cardiac systolic and diastolic function. The study included 90 female subjects who performed control of thyroid hormonal status at the Institute of Nuclear Medicine at the University of Sarajevo Clinics Centre and who previously were untreated for the thyroid functional disorders. The study sample was divided in three groups based on the thyroid hormones levels: a) hyperthyroid group (n= 30) b) hypothyroid group (n=30) and c) euthyroid (control). Echocardiography measurements were performed on commercially available Toshiba, SSH 140.Before the therapy no statistically significant differences in the peak early and late mitral inflow velocities (E/A) values between the study groups was observed, but the mean left ventricular ejection fraction (LVEF) in hypothyroid group was significantly lower (58,30±1,05) compared to control (64,96±0,71) and hyperthyroid group (64,69±1,31) (p<0,001). In hypothyroid group we found significant increase in mean LVEF (58,30±1,05 vs. 64,95±0,86, p<0,01) and E/A (1,06±0,07 vs. 1,17±0,08; p=0,01) values after the normalization of thyroid hormone status. Thyroid dysfunctional states were not associated with impaired diastolic function, probably due to the short duration of thyroid dysfunction and timely and successful conversion therapy. Systolic function however was significantly reduced in hypothyroid patients but subsequently improved after the adequate therapy. Early diagnostic approach in patients with thyroid dysfunctional states is important for avoidance of cardiac complications that accompany these disorders.

Antiangiogenic Drugs

Therapy with angiogenesis inhibitors is undoubtedly an advancement in cancer treatment; however, it is associated with a risk of developing cardiotoxicity, which most often manifests in myocardial contractile dysfunction or an increased risk of thromboembolic events. Heart failure is observed in 2–4% of patients treated with bevacizumab and in 3–8% of patients on antiangiogenic tyrosine kinase inhibitors. The proposed pathomechanisms underlying the impairment in systolic function during antiangiogenic drug treatment include mitochondrial dysfunction, a secondary reduction in cardiomyocyte ATP production and redox imbalance, which may contribute to pathological states known as “free radical diseases”. Additionally, therapy with angiogenesis inhibitors may also cause cardiac oxidative stress. The risk factors for cardiac complications include arterial hypertension, which is a known “class effect” of this class of drugs, as well as a number of other factors such as age, comorbidities, prior radiotherapy and baseline left ventricular ejection fraction. The cardiovascular diseases are still the first cause of death in the world. The more effective oncological treatment becomes, the more often comorbidities occur. This fact seems to demand interdisciplinary approach from investigators and practitioners. This article presents the current state of knowledge on the molecular mechanisms of cardiotoxicity of antiangiogenic drugs used in routine clinical practice.

Diastolic function assessed my CMR feature tracking is a predictor for outcomes in patients with suspected myocarditis and preserved left ventricular ejection fraction Background Impairment of left ventricular (LV) systolic function was reported to be a valuable predictor for outcomes in patients with myocarditis. However, in patients with myocarditis and preserved LV systolic function, prediction of outcomes remains challenging. So far, minimal data exists about the prognostic role of diastolic function, as assessed by cardiac magnetic resonance imaging (CMR) in the clinical setting of suspected myocarditis. Purpose To determine the predictive value of LV diastolic function in patients with suspected myocarditis and preserved LV ejection fraction (LVEF). Methods In patients referred for CMR with clinically suspected myocarditis and LVEF≥50%, diastolic function was assessed by CMR feature tracking (FT). The primary endpoint was defined as a composite of major adverse cardiovascular events (MACE) including hospitalization for heart failure, recurrent myocarditis, sustained ventricular tachycardia and all-cause death. Results Of 381 patients included with clinically suspected myocarditis (216, 56.7% male, mean age 45.7 ± 16.4 years) late gadolinium enhancement (LGE) was present in 124 (32.4 %) of patients (mean LGE extent 4.9 ± 5.0 g). MACE occurred in 25 (6.6%) individuals at a median follow-up time of 4.5 years. In a univariate cox-regression model, radial, circumferential and longitudinal early diastolic strain rate (EDSR) and circumferential late diastolic strain rate were significantly associated with MACE. After adjustment for age, gender and extent of LGE, radial EDSR remained an independent predictor for MACE (HR = 2.26, 95% CI 1.06 to 4.8; p = 0.034). Conclusion Diastolic strain rate, as assessed by CMR-FT, can be useful in the prediction of outcomes in patients with myocarditis and preserved LVEF.

Purpose: The purpose of this study was to evaluate whether a association exits among overweight and obesity and left ventricular systolic and diastolic functions in patients admitted with first ST-elevation myocardial infarction (STEMI). Methods: The present study was performed on 451 consecutive patients diagnosed with first STEMI (376 men, 75 women; mean age 56.1±10.8 years). The patients were classified into three groups based on their body mass index (BMI) as normal weight (BMI < 25 kg/m2), overweight (BMI: 25-29.9 kg/m2) and obese (BMI > 30 kg/m2). Echocardiographic features were evaluated and compared among the three groups. Results: Mitral annulus E velocities were higher in obese individuals than normal weight group (p < 0.01). In contrast, mitral A velocities were lower (p =0.03); consequently, E\A and E'\A' ratios were lower (both p =0.01) in the obese group with respect to normal weight group. When the correction of entire variations existing among the groups were performed using multivariate linear regressions analyses, it turned out that BMI was independently associated with E/A (β= -0.19, p =0.044) and with E'/A' (β= -0.016, p=0.021). Ejection fraction, wall motion score index and myocardial S velocities were comparable among the study groups (p > 0.05). Conclusion: These results suggest that while obesity has no adverse effect on the left ventricular systolic function, it has unfavorable consequences on the left ventricular diastolic function in the patients with first STEMI. In contrast, no unfavorable effects of overweight on the left ventricular systolic and diastolic function were detected.

Background: The prognostic importance of right ventricular (RV) dysfunction has been suggested in patients with systolic heart failure (due to primary or secondary dilated cardiomyopathy - DCM). Tricuspid annular plane systolic excursion (TAPSE) is a simple, feasible, reality, non-invasive measurement by transthoracic echocardiography for evaluating RV systolic function. Objectives: To evaluate TAPSE in patients with primary or secondary DCM who have left ventricular ejection fraction ≤ 40% and to find the relation between TAPSE and LVEF, LVDd, RVDd, RVDd/LVDd, RA size, severity of TR and PAPs. Materials and Methods: 61 patients (36 males, 59%) mean age 58.6 ± 14.4 years old with clinical signs and symtomps of chronic heart failure which caused by primary or secondary DCM and LVEF ≤ 40% and 30 healthy subject (15 males, 50%) mean age 57.1 ± 16.8 were included in this study. All patients and controls were underwent echocardiographic examination by M-mode, two dimentional, convensional Dopler and TAPSE. Results: TAPSE is significant low in patients compare with the controls (13.93±2.78 mm vs 23.57± 1.60mm, p<0.001). TAPSE is linearly positive correlate with echocardiographic left ventricular ejection fraction (r= 0,43; p<0,001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation was found with LVDd and PAPs. Conclusions: 1. Decreased RV systolic function as estimated by TAPSE in patients with systolic heart failure primary and secondary DCM) compare with controls. 2. TAPSE is linearly positive correlate with LVEF (r= 0.43; p<0.001) and linearly negative correlate with RVDd (r= -0.39; p<0.01), RVDd/LVDd (r=-0.33; p<0.01), RA size (r=-0.35; p<0.01), TR (r=-0.26; p<0.05); however, no correlation is found with LVDd and PAPs. 3. TAPSE should be used routinely as a simple, feasible, reality method of estimating RV function in the patients systolic heart failure DCM (primary and secondary).

Abstract Background Angiogenesis participates in re-establishing microcirculation after myocardial infarction (MI). Purpose In this study, we aim to further understand the role of the anti-angiogenic isoform vascular endothelial growth factor (VEGF)-A165b after MI and explore its potential as a co-adjuvant therapy to coronary reperfusion. Methods Two mice MI models were formed: 1) permanent coronary ligation (non-reperfused MI), 2) transient 45-min coronary occlusion followed by reperfusion (reperfused MI); in both models, animals underwent echocardiography before euthanasia at day 21 after MI induction. Serum and myocardial VEGF-A165b levels were determined. In both experimental MI models, functional and structural implication of VEGF-A165b blockade was assessed. In a cohort of 104 ST-segment elevation MI patients, circulating VEGF-A165b levels were correlated with cardiovascular magnetic resonance-derived left ventricular ejection fraction at 6-months and with the occurrence of adverse events (death, heart failure and/or re-infarction). Results In both models, circulating and myocardial VEGF-A165b presence was increased 21 days after MI induction. Serum VEGF-A165b levels inversely correlated with systolic function evaluated by echocardiography. VEGF-A165b blockage increased capillary density, reduced infarct size, and enhanced left ventricular function in reperfused, but not in non-reperfused MI experiments. In patients, higher VEGF-A165b levels correlated with depressed ejection fraction and worse outcomes. Conclusions In experimental and clinical studies, higher serum VEGF-A165b levels associates with a worse systolic function. Its blockage enhances neoangiogenesis, reduces infarct size, and increases ejection fraction in reperfused, but not in non-reperfused MI experiments. Therefore, VEGF-A165b neutralization represents a potential co-adjuvant therapy to coronary reperfusion. Funding Acknowledgement Type of funding source: Public grant(s) – National budget only.

AbstractTo evaluate the effect of age and parity on maternal cardiac diastolic function in second trimester among pregnant women with normal left ventricular ejection fraction. To analyze the correlation between impaired diastolic function and pre-eclampsia. It had been suggested that maternal cardiac adaptations during pregnancy differed between nulliparous and primiparous women and also varied according to age. Impaired cardiac function may precede pre-eclampsia. Therefore, we examined the effects of parity and age on cardiac diastolic function during pregnancy and whether impaired diastolic function during the second trimester correlates with pre-eclampsia. Women with singleton pregnancies at 13 + 0 to 27 + 6 weeks’ gestation and left ventricular ejection fraction (LVEF) ≥ 50% were retrospectively identified. Diastolic function parameters were assessed using transthoracic echocardiography. Pre-eclampsia was identified from medical records. The effect of age and parity on maternal cardiac diastolic function as well as the correlation between impaired diastolic function and occurrence rate of pre-eclampsia were examined. 376 pregnant women were included (median age: 30 years; median gestational age: 14 weeks; 171 primiparous women). LVEF was 66%. Impaired cardiac diastolic function was seen in 7.8% of pregnant women < 35 years compared with 28.6% of those ≥ 35 years (p = 0.000). ROC curve showed women with maternal age over 32 began to have a higher rate of impaired cardiac diastolic function (AUC = 0.704, p = 0.000, sensitivity = 54.5%, specificity = 75.3%). There was no difference in diastolic function indices between maternal women grouped by parity. Higher maternal age was an independent risk factor of declining Em (p < 0.05). Em < 13 cm/s was significantly associated with pre-eclampsia occurrence (HR 8.56; 95% CI 3.40–21.57) after being adjusted for confounders. Maternal age is an independent risk factor for diastolic function decline. There is no difference in cardiac diastolic function between nulliparous women and primiparous women. Pre-eclampsia occurrence is significantly higher in patients with impaired diastolic function at mid-gestation. The application of risk grading using diastolic function at mid-gestation may improve the survival outcomes of pregnant women.

Background. While the mitral annular plane systolic excursion (MAPSE) has been suggested as a surrogate measurement of left ventricular ejection fraction, less is known about the relative value of mitral annular ascent (MAa).Methods. Our database was queried for complete transthoracic echocardiograms performed for any clinical indication. Baseline echocardiographic measurements were compared to determine any correlation between MAa and traditional Echo-Doppler echocardiographic measures to characterize left ventricular diastolic dysfunction (LVDD).Results. Patients with normal LV diastolic function were younger (41±13years) than patients with LVDD (stage 1:61±13years; stage 2:57±14years; and stage 3:66±17years;p=0.156). LV ejection fraction decreased in patients with stage 2 LVDD (63±17%) and was further reduced in patients with stage 3 LVDD (28±21;p=0.003).Discussion. While a vigorous MAa excursion was seen in patients with stage 1 LVDD, MAa significantly decreased in stage 2 and stage 3 LVDD patients. Our results highlight the importance of atrioventricular coupling, as MAa motion seems to reflect changes in left atrial pressure. Additional studies are now required to better examine atrioventricular interactions and electromechanical coupling that might improve our assessment of LV diastolic function.

Microvascular obstruction (MVO) is negatively associated with cardiac structure and worse prognosis after ST-segment elevation myocardial infarction (STEMI). Epithelial cell adhesion molecule (EpCAM), involved in endothelium adhesion, is an understudied area in the MVO setting. Purpose. We aimed to evaluate whether EpCAM is associated with the appearance of cardiac magnetic resonance (CMR)-derived MVO and long-term systolic function in reperfused STEMI. Methods. We prospectively included 106 patients with a first STEMI treated with primary percutaneous coronary intervention, quantifying serum levels of EpCAM 24 hours post-reperfusion. All patients underwent CMR imaging 1 week and 6 months post-STEMI. The independent correlation of EpCAM with MVO, systolic volume indices, and left ventricular ejection fraction (LVEF) was evaluated. Results. The mean age of the sample was 59 ± 13 years and 76% were male. Patients were dichotomized according to EpCAM median (4.48 pg/mL). At 1-week CMR, lower EpCAM was related to extensive MVO (p-value = 0.02) and greater infarct size (p-value = 0.02). At presentation, only EpCAM values were significantly associated with the presence of MVO in univariate (Odds Ratio [95% confidence interval] (OR [95% CI]): 0.58 [0.38-0.88], p-value = 0.01) and multivariate logistic regression models (OR [95% CI]: 0.54 [0.34-0.85], p-value = 0.007). Although MVO tends to resolve at chronic phases, decreased EpCAM was associated with worse systolic function: depressed LVEF (p-value = 0.009) and higher left ventricular end-systolic volume (p-value = 0.04). Conclusions. EpCAM is associated with occurrence of CMR-derived MVO at acute phases and long-term adverse ventricular remodeling post-STEMI. Future studies are needed to confirm EpCAM as biomarker, and eventually biotarget in STEMI pathophysiology.

Introduction: Dengue, a vector borne viral infection transmitted by Aedes mosquito has recently become a major public health concern in the tropical regions of the world. In addition to the two major life threatening complications- Dengue Haemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), a variety of cardiac complications have been recognised, the most common being myocarditis. Aim: To study and compare the quantity of different cardiac biomarkers in patients of Dengue Fever with and without myocarditis. Materials and Methods: This was a hospital-based retrospective observational study done in a Tertiary Care Hospital, Kolkata, West Bengal, India from June 2019 to November 2019. Dengue patients with diagnosed myocarditis on day 7 of fever based on electro and echocardiogram changes of left ventricular ejection fraction less than 50% were considered as cases (n=41). Age and sex matched dengue patients with normal electro and echocardiogram changes were considered as control (n=43). After obtaining Institutional Ethics Committee Clearance, laboratory data were collected from samples coded and assayed for markers of acute cardiac myocyte damage such as total Creatine Kinase (CK), CK-Muscle Brain (CK-MB), Troponin T (Trop T) and cardiac failure biomarker N-Terminal pro Brain Natriuretic Peptide (NT-proBNP). Statistical analysis of the data was performed using Statistical Package for Social Sciences (SPSS 20). Results: Cardiac biomarkers CK, CK-MB, Trop T and NT-proBNP levels in cases were higher compared to controls (p-value <0.05). Trop T and NT-proBNP were positively correlated to each other (r-value: 0.44). Trop T changes could also predict significantly the rise in NT-proBNP in circulation (p<0.05). Conclusion: It reconfirmed the need of routine monitoring of cardiac biomarkers in conjunction with other cardiac function tests in early diagnosis and or management of myocarditis, a severe complication of Dengue Viral Infection (DENV).
