Background: Aluminum Phosphide (AlP) is a well-known rodenticide and insecticide, used as a fumigant to control pests and rodents in grain-storage facilities. Its intoxication presents a medical emergency that requires early rigorous management. This study aimed to investigate cardiac function by Electrocardiogram (ECG) changes in patients with AlP intoxication. We also explored the potential relationship between low bicarbonate and cardiac function. Methods: This cross-sectional study investigated 42 patients in the age range of 17-47 years, with a history of orally-administered AlP poisoning, known as “rice tablet”, admitted to the toxicology ward of Imam Reza Hospital from March 2019 to March 2021. The study patients’ demographic data were collected by trained interviewers, using pretested questionnaires. Systolic and diastolic blood pressure, as well as blood samples, were measured 12 hours from admission. Echocardiography was performed during the first 12 hours and on the fifth-day post-admission. All statistical analysis was performed using R 3.6.1. The significance level was set at 0.05 for all statistical tests. Results: In total, 48.78% of patients presented normal bicarbonate levels, and 24.39% and 26.83% had moderate and severe acidity, respectively. Moderately and severely decreased Left Ventricular Ejection Fraction (LVEF) was observed among 21 (51.2%) and 10 (24.4%) patients, respectively. Furthermore, mild Right Ventricular (RV) function was observed among 11 (26.8%) patients. A statistically significant association was observed between bicarbonate level and RV function (P<0.001) and LVEF (P<0.001). Besides, 19.5% of the explored patients expired. The proportion of expired patients was significantly higher in patients with mild RV function, compared to the other patients (P<0.001). Conclusion: Acute AlP intoxication is a worldwide serious problem. Severe metabolic acidosis and ECG abnormalities are associated with poor outcomes in this respect. Thus, conducting early ECG and echocardiography could be desirable instruments to predict prognosis. There is no antidote for AlP poisoning; thus, the replacement of a safer agent for in-store grain protection is strongly suggested.

Objective There is still a great deal to learn about the influence of gender in systemic sclerosis (SSc). In this respect, national registries provide large and homogeneous patient cohorts for analytical studies. We therefore investigated a wide-ranging and well-characterized SSc series with the aim of identifying gender differences in disease expressions, with a special focus on demographic, clinical and serological characteristics. Methods A multicenter SSc cohort of 2,281 patients, 247 men, was recruited in the Italian SPRING (Systemic Sclerosis PRogression INvestiGation) registry. Demographic data, disease manifestations, serological profile and internal organ involvement were compared. Results The overall female/male ratio was 8.2/1. Female/male ratios for limited SSc, diffuse SSc and sine SSc subsets were 8.7/1, 4.9/1, and 10.7/1 respectively. A shorter Raynaud's onset to SSc diagnosis, an increased prevalence of diffuse cutaneous subset, renal crisis, and digital ulcers were found in males, while a significant higher percentage of sicca syndrome, serum ANA, anti-ENA, anti-La/SSB, and anti-CENP-1 was detected in the female group. Males exhibited lower left ventricular ejection fraction, higher prevalence of conduction blocks, arrhythmias, ground glass and honeycombing. Moreover, forced vital capacity and total lung capacity were medially lower in men than in women. Finally, males were more frequently treated with immunosuppressive drugs. Conclusion Our study further supports the presence of several gender-related differences in SSc patients. These differences were pronounced as regards the severity of cutaneous, peripheral vascular and cardiopulmonary involvement for male patients, whereas an increased prevalence of sicca syndrome and a specific autoantibody profile characterize the female gender.

Aims The purpose of this study was to evaluate whether yoga training in addition to standard medical therapy can improve cardiac function and reduce N terminal pro B-type natriuretic peptide (NT pro BNP) in heart failure (HF). Methods 130 patients were recruited and randomized into two groups: Control Group (CG) ( n = 65), Yoga Group (YG). In YG, 44 patients and in CG, 48 patients completed the study. Cardiac function using left ventricular ejection fraction (LVEF), myocardial performance index (Tei index), and NT pro BNP, a biomarker of HF, was assessed at baseline and after 12 weeks. Result Improvement in LVEF, Tei index, and NT pro BNP were statistically significant in both the groups. Furthermore, when the changes in before and after 12 weeks were in percentage, LVEF increased 36.88% in the YG and 16.9% in the CG, Tei index was reduced 27.87% in the YG and 2.79% in the CG, NT pro BNP was reduced 63.75% in the YG and 10.77% in the CG. The between group comparisons from pre to post 12 weeks were significant for YG improvements (LVEF, P < 0.01, Tei index, P < 0.01, NT pro BNP, P < 0.01). Conclusion These results indicate that the addition of yoga therapy to standard medical therapy for HF patients has a markedly better effect on cardiac function and reduced myocardial stress measured using NT pro BNP in patients with stable HF.

The sympathetic nervous system and proinflammatory cytokines are believed to play independent roles in the pathophysiology of heart failure. However, the recent identification of Epac (exchange protein activated by cyclic AMP), a new cyclic AMP-binding protein that directly activates Rap1, have implicated that there may be a potential cross talk between the sympathetic and cytokine signals. In order to examine the role of Epac in cytokine signal to regulate cardiac function, we have generated transgenic mice expressing the human Epac1 gene under the control of alpha-cardiac myosin heavy chain promoter (Epac1-TG), and examined their response in lipopolysaccharide (LPS)-induced cardiac dysfunction, a well established model for sepsis-induced cardiac dysfunction. Sepsis-induced cardiac dysfunction results from the production of proinflammatory cytokines. At baseline, left ventricular ejection fraction (LVEF) was similar (TG vs. NTG, 67±1.7 vs. 69±2.1%, n =7–9). The degree of cardiac hypertrophy (LV(mg)/tibia(mm)) was also similar at 3 months old (TG vs. NTG 4.0±0.1 vs. 4.2±0.1, n =5–6), but it became slightly but significantly greater in Epac1-TG at 5 month old (TG vs. NTG 4.9±0.1 vs. 4.4±0.1, p< 0.05, n =5–7). LPS (5mg/kg) elicited a significant and robust reduction of LVEF in both Epac1-TG and NTG, but the magnitude of this decrease was much less in Epac1-TG at 6 hr after injection (TG vs. NTG 48±2.4 vs. 57±1.8%, p< 0.01, n =6–9). At 24 hr after injection, cardiac function was restored to the baseline in both Epac1-TG and NTG. We also examined the activation of JAK-STAT pathway at 24 hr after injection. The tyrosine phosphorylation of STAT1 (Tyr701) and STAT3 (Tyr705) in LV, which is an indicator of STAT activation, was reduced to a greater degree in Epac1-TG by 31±8.8% ( p< 0.05, n =4) and 29±5.9% ( p< 0.05, n =7), respectively, relative to that in NTG. Taken together, Epac1 protects the heart from the cytokine-induced cardiac dysfunction, at least in part, through the inhibition of the JAK-STAT pathway, suggesting the beneficial role played by sympathetic signal to antagonize proinflammatory cytokine signal in heart failure.

Background: we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of exercise training on cardiac function and circulating biomarkers outcomes among women with breast cancer (BC) receiving anthracycline or trastuzumab-containing therapy. Methods: PubMed, EMBASE, Cochrane Library, Web of Science and Scopus were searched. The primary outcome was change on left ventricular ejection fraction (LVEF). Secondary outcomes included diastolic function, strain imaging and circulating biomarkers. Results: Four RCTs were included, of those three were conducted during anthracycline and one during trastuzumab, involving 161 patients. All trials provided absolute change in LVEF (%) after a short to medium-term of treatment exposure (≤6 months). Pooled data revealed no differences in LVEF in the exercise group versus control [mean difference (MD): 2.07%; 95% CI: −0.17 to 4.34]. Similar results were observed by pooling data from the three RCTs conducted during anthracycline. Data from trials that implemented interventions with ≥36 exercise sessions (n = 3) showed a significant effect in preventing LVEF decline favoring the exercise (MD: 3.25%; 95% CI: 1.20 to 5.31). No significant changes were observed on secondary outcomes. Conclusions: exercise appears to have a beneficial effect in mitigating LVEF decline and this effect was significant for interventions with ≥36 exercise sessions.

As the impairment of myocardial microenvironments due to coronary microembolization (CME) compromises the treatment effect of percutaneous coronary intervention and leads to adverse prognosis, we hypothesized that endothelial progenitor cells (EPCs) transplantation could improve cardiac function in the condition of CME. Low- (2 × 105) and high- (2 × 106) dose rat bone marrow-derived EPCs were transplanted in a model of CME. To develop a CME model, rats were injected with autologous micro-blood-clots into the left ventricle. Echocardiograph was examined before and 1, 7, and 28 days after EPC transplantation; serum cardiac troponin I (cTNI), von Willebrand factor (vWF), and cardiac microRNA expression were examined one day after EPCs transplantation. Heart morphology and vascular endothelial growth factor (VEGF), vWF, and basic fibroblast growth factor (bFGF) expression were examined one day after EPC transplantation. After 10 days of culture inductions, BM-EPCs have high purity as confirmed by flow cytometry. Cardiac function reflected by left ventricular ejection fraction significantly decreased after CME treatment and rescued by low-dose EPC. Compared to the sham group, cTNI and vWF serum levels increased significantly after CME treatment and rescued by low-dose EPC and high-dose EPC. Low-dose EPC treatment decreased myocardial necrosis and fibrosis and elevated cardiac expression of VEGF and vWF, while decreasing the cardiac expression of bFGF. Low-dose EPC treatment significantly suppressed cardiac expression of microRNA-19a but significantly enhanced microRNA-21, microRNA-214, and microRNA-486-3p expression. In conclusion, our results indicate that low-dose EPC transplantation may play a proangiogenic, antifibroblast, antifibrosis, and antinecrosis role and enhance cardiac function in a rat model of CME through a microRNA-related pathway.

522 Background: Cardiac toxicity associated with anthracylines and more recently herceptin used in adjuvant breast cancer treatment is well recognized. Little is known about long term cardiac function as measured by left ventricular ejection fraction (LVEF) in patients post therapy. We analyzed the database of a randomized Phase 3 NCIC CTG study to assess changes over time in LVEF. Methods: Between 1989–1993, 710 pre/perimenopausal patients with node positive breast cancer were allocated to receive CEF (cyclophosphamide (C) 75 mg/m2 po d 1–14, epirubicin (E) 60 mg/m2 IV and fluorouracil (F) 500mg/m2 IV d1,d8) or CMF (C 100mg/m2 po d1–14, methotrexate (M) 40mg/m2 and F 600mg/m2 IV d1,8) given every 28 days for 6 cycles. The 10 year relapse-free survival was 52% (CEF) vs 45% (CMF), HR 1.31; stratified log rank, P=.007 (JCO, 2005,23;5166). LVEF was measured on both arms at baseline, months 6, 12, 36, and 60. Results: Compliance was good with measurements available on 100% of women at baseline, and 39% and 40% of patients at 60 months on the CEF and CMF arms respectively. Changes in LVEF from baseline are shown in the table . Conclusion: Changes in cardiac function as measured by a decrease in LVEF are not infrequent in patients after adjuvant therapy, even in the absence of anthracyclines. At 60 months, decreases of >10% were seen in up to 25% of patients receiving epirubicin administered at a cumulative dose of 720mg/m2 and in up to 10% of patients receiving CMF on whom measurements were available. The clinical significance of these findings needs to be assessed.

Objectives. Ginsenoside Rg3 is one of the ginsenosides which are the main constituents isolated from Panax ginseng. Previous study demonstrated that ginsenoside Rg3 had a protective effect against myocardial ischemia/reperfusion- (I/R-) induced injury. Objective. This study was designed to evaluate the effect of ginsenoside Rg3 on cardiac function impairment induced by myocardial I/R in rats. Methods. Sprague-Dawley rats were subjected to myocardial I/R. Echocardiographic and hemodynamic parameters and histopathological examination were carried out. The expressions of P53, Bcl-2, Bax, and cleaved caspase-3 and the levels of TNF-α and IL-1β in the left ventricles were measured. Results. Ginsenoside Rg3 increased a left ventricular fractional shortening and left ventricular ejection fraction. Treatment with ginsenoside Rg3 also alleviated increases of left ventricular end diastolic pressure and decreases of left ventricular systolic pressure and ±dp/dt in myocardial I/R-rats. Ginsenoside Rg3 decreased apoptosis cells through inhibiting the activation of caspase-3. Ginsenoside Rg3 also caused significant reductions of the contents of TNF-α and IL-1β in left ventricles of myocardial I/R-rats. Conclusion. The findings suggested that ginsenoside Rg3 possessed the effect of improving myocardial I/R-induced cardiac function impairment and that the mechanism of pharmacological action of ginsenoside Rg3 was related to its properties of antiapoptosis and anti-inflammation.

Basic and clinical studies have shown that bone marrow cell therapy can improve cardiac function following infarction. In experimental animals, reported stem cell-mediated changes range from no measurable improvement to the complete restoration of function. In the clinic, however, the average improvement in left ventricular ejection fraction is around 2% to 3%. A possible explanation for the discrepancy between basic and clinical results is that few basic studies have used the magnetic resonance (MR) imaging (MRI) methods that were used in clinical trials for measuring cardiac function. Consequently, we employed cine-MR to determine the effect of bone marrow stromal cells (BMSCs) on cardiac function in rats. Cultured rat BMSCs were characterized using flow cytometry and labeled with iron oxide particles and a fluorescent marker to allow in vivo cell tracking and ex vivo cell identification, respectively. Neither label affected in vitro cell proliferation or differentiation. Rat hearts were infarcted, and BMSCs or control media were injected into the infarct periphery ( n = 34) or infused systemically ( n = 30). MRI was used to measure cardiac morphology and function and to determine cell distribution for 10 wk after infarction and cell therapy. In vivo MRI, histology, and cell reisolation confirmed successful BMSC delivery and retention within the myocardium throughout the experiment. However, no significant improvement in any measure of cardiac function was observed at any time. We conclude that cultured BMSCs are not the optimal cell population to treat the infarcted heart.

AbstractBackgroundThe global prevalence of obesity in school-age children and adolescents has increased in recent decades. Obesity modifies some aspects of the cardiovascular system in order to preserve the body homoeostasis. Echocardiography to study ventricular function plays an important role in the evaluation of pathological re-modelling associated with left ventricular dysfunction. The aim of this study was to evaluate the left ventricle function and structure with conventional echocardiography and to analyse the longitudinal deformity of the left ventricle using myocardial-tracking signals in a group of severely obese adolescents.Methods and resultsWe carried out a descriptive cross-sectional study. We describe the evaluation of the left ventricle using conventional bi-dimensional echocardiography and the myocardial-tracking signals in severely obese adolescents. There were 34 severely obese adolescents included in our study; 52% had a left ventricular ejection fraction<55%, the left ventricular end-diastolic diameter was increased in 70.5% of patients, and 32.3% had an increase in left ventricular mass. On average, 78.9% had abnormal values of left ventricle longitudinal deformations. The number of segments affected per patient was, on average, 5.8, with the anterior apical segment being the most commonly affected. There was a decrease in global longitudinal deformity in 79.4% of the cases.ConclusionMore than half of this group of asymptomatic severely obese adolescents showed abnormalities in left ventricular structure and function evaluated using traditional echocardiographic methods, but 100% of the cases showed abnormalities in longitudinal deformation in at least one of the 17 left ventricle segments evaluated using myocardial-tracking signals.

Abstract Background: The GH receptor (GHR) exon 3 polymorphism occurs at a genomic level. Approximately 50-60% of the population is homozygous for the exon-3 containing genotype (+3/+3), 30-40% are heterozygous (+3/-3) and 10-20% are homozygous for the exon-3 lacking genotype (-3/-3). Some studies suggest that children homo- and heterozygous for the GHR exon 3 lacking genotype (-more efficient 3/-3 and +3/-3, respectively) respond better to treatment with exogenous rhGH and there is also in vitro evidence showing a more efficient signal transduction through this exon 3 deleted isoform. Some studies have found that patients with acromegaly harboring the exon 3-deleted genotype may have a higher prevalence of diabetes and hypertension. Hypothesis and Objective: Patients with active acromegaly harboring the exon 3-lacking GHR genotype may have more echocardiographic abnormalities than those who are homozygous for the exon 3 containing genotype. Patients and Methods: This is a cross-sectional study of patients with active acromegaly, defined by an IGF-1 level &gt; 1.3 times the upper limit of normal (x ULN), who underwent transthoracic echocardiography. Exon-3 GHR genotype was determined by PCR using previously described sense and antisense primers. Results: The cohort consisted of 28 patients, 54% female, with a mean age of 51 ± 12 years. Mean disease duration at the time of echocardiographic examination was 4.48 ± 4.7 years; median basal GH and IGF-1 were 12 ± 26 ng/mL and 2.4 ± 1.04 x ULN. The prevalence of hypertension and diabetes were 43% and 36%, respectively. Fifty three percent of the patients were homozygous for the exon 3-containaing genotype (+3/+3), 18% were homozygous for the exon 3-lacking genotype (-3/-3) and 29% were heterozygous (+3/-3). Clinical and biochemical features did not differ between patients with the different GHR genotypes, except for hypertension that was more prevalent in the +3/+3 genotype group (60% vs 23%, p= 0.04). The frequency of the different echocardiographic parameters was similar among groups (left ventricular hypertrophy 33% vs 15%, p= 0.27; diastolic dysfunction 47% vs 31%, p= 0.39; subclinical systolic dysfunction 42% vs 54%, p= 0.54; left ventricular ejection fraction 59±10% vs 60±16%, p= 0.83); aortic valve abnormalities 19% vs 15%, p=0.63; mitral valve abnormalities 46% vs 15%, p=0.07). Conclusions: Echocardiographic abnormalities in patients with active acromegaly do not differ among patients with the different GHR exon 3 genotypes. The clinical spectrum of acromegaly varies considerably. Although such variability is usually related to the severity of the hypersomatotropinemia, in many patients this is not the case.
