Abstract Background The SARS-CoV-2 outbreak has led to radical transformation in social, economic, and healthcare systems. This may lead to profound indirect consequences on clinical presentation and management of patients with ST-segment–elevation myocardial infarction. Objectives The objective of this study was to describe the characteristics, management, and outcomes of patients admitted with acute myocardial infarction with ST-segment elevation (STEMI), in two tertiary reference hospitals during the SARS-CoV-2 outbreak and compare them with patients admitted in the previous year. Methods We analyzed data from a multicenter STEMI registry from reference centers in the South Region of Brazil from March 2019 to May 2021. The beginning of the COVID-19 outbreak was considered to be March 2020 and compared to the same period in 2019. Only patients with STEMI submitted to primary percutaneous coronary intervention (PCI) were included in the analysis. Mortality rates were compared with chi-square test. All hypothesis tests had a two-sided significance level of 5%. Results A total of 1169 patients admitted with STEMI were enrolled in our registry, 635 of whom were admitted during the pandemic period. The mean age of our sample was 61.6 (± 12.4) years, and 66.7% of patients were male. Pain-to-door time and door-to-balloon time were longer during the pandemic period. However, there was no difference in mortality rates or major adverse cardiovascular outcomes (MACE). Conclusions We observed a stable incidence of STEMI cases in our registry during the SARS-CoV-2 outbreak with higher pain-to-door time and door-to-balloon time, without any influence on mortality rates however.

Abstract Fulminant necrotizing eosinophilic myocarditis (FNEM) is a rare form of EM characterized by biventricular heart failure with hemodynamic deterioration, often requiring inotropes or mechanical circulatory support. Here, we report a case of a 43-year-old healthy woman with FNEM who was admitted with acute heart failure that rapidly progressed to cardiogenic shock and electrical storm, culminating in cardiac arrest. Early diagnosis and prompt administration of corticosteroids in combination with veno-arterial extracorporeal membrane oxygenation allowed complete recovery of biventricular systolic function.

Abstract Background Firefighters are regularly exposed to stress and have a high incidence of cardiovascular events. Investigating cardiovascular and autonomic reactivity to acute mental stress (AMS) and its association with adiposity may contribute to explaining the increased cardiovascular risk in these professionals. Objectives To evaluate cardiovascular and autonomic reactivity to AMS in firefighters while considering adiposity parameters. Methods This study recorded the blood pressure and heart rate (HR) of twenty-five firefighters (38±8 years) at rest, while performing the Stroop color-word test to induce AMS, and recovery. Cardiac autonomic modulation (HR variability), baroreflex sensitivity (BRS — sequential method), and adiposity (electrical bioimpedance) were assessed. One-way or two-way analysis of variance followed by Tukey’s post hoc test and multiple linear regression were performed. The significance level was P<0.05. Results The AMS increased mean arterial pressure (MAP — Δ16±13 mmHg) and HR (Δ14±7 bpm) ( P <0.05). These responses were associated with parasympathetic modulation withdrawal (RMSSD: baseline: 29.8±18 vs. AMS: 21.5±14 ms; High-frequency: baseline: 5.2±1.4 vs. AMS: 4.5±1.3 Ln ms 2 ; P <0.05) and decreased in the Up gain of the baroreflex (baseline: 8.9±5.1 vs. AMS: 6.3±3.0 mmHg/ms; P <0.05). Groups divided by HR reactivity peak showed parasympathetic modulation withdrawal only in firefighters with lower adiposity (RMSSD: baseline: 27.8±17.6 vs. AMS: 14.4±9.2 ms; High-Frequency: baseline: 5.3±1.2 vs. AMS: 3.8±1.4 Ln ms 2 ; P <0.05). Fat percentage (β = -0.499), BRS (β = 0.486), and sympathetic/parasympathetic balance (β = -0.351) were predictors of HR reactivity ( P <0.05). Conclusion Our results demonstrated that HR reactivity to AMS modulated by cardiac vagal withdrawal seems to be influenced by body composition in this group of firefighters. events (AMS professionals parameters twentyfive twenty five 38±8 388 38 8 (38± years rest colorword color word recovery variability, variability , variability) method, method method) electrical bioimpedance assessed Oneway One way twoway two Tukeys Tukey s performed P005 0 05 P<0.05 MAP Δ1613 Δ Δ16 13 Δ16±1 mmHg Δ14±7 Δ147 Δ14 7 (Δ14± bpm <0.05. 005 <0.05 .

Abstract Background: People with haemophilia (PwH) are living longer. Therefore, they can develop atherosclerotic cardiovascular disease (ASCVD). Electrocardiogram (ECG) alterations may be a sign of initial ASCVD before the occurrence of symptoms. Objective: To describe the prevalence of resting ECG alterations among PwH adults asymptomatic for ASCVD. Methods: PwH aged ≥ 30 years without previous ASCVD events were considered for the analysis. Resting ECG traces were analysed according to international reference values and the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) results for asymptomatic Brazilian men. Based on the established normal values and using the QT index, we further described the altered ECGs as minor or major changes, according to the Minnesota Code. Differences between prevalences were evaluated by Pearson's χ2 test. Differences between medians were evaluated by the Mann-Whitney U test. A p-value < 0.05 was accepted as statistically significant. Results: A total of 64 PwH were included in the study. Median age was 44 years (interquartile range 35-52). Most patients had haemophilia A (81%) and 47% were severe. The prevalence of obesity, systemic arterial hypertension (SAH), diabetes mellitus (DM), and dyslipidaemia were 16%, 56%, 14%, and 72%, respectively. All the PwH had sinus rhythm, except for one, who had an implanted pacemaker due to idiopathic third-degree atrioventricular block. Altered ECGs were found in 25% and 30% of PwH, according to established criteria and ELSA-Brasil criteria, respectively. Major changes were found in eight (13%) PwH according to the Minnesota Code, including two ECGs with ischaemia-like wall inactivity. Conclusions: The prevalence of altered ECG varied from 25% to 30% among asymptomatic PwH. Background (PwH longer Therefore .

Abstract Breast cancer (BC) is the most common malignant neoplasia in women and is responsible for one in six deaths from cancer in the female population. Five years after diagnosis, BC survival rates currently exceed 80%. Cardiovascular disease (CVD) is a frequent cause of morbidity and mortality in BC, mainly in patients receiving cardiotoxic drugs (anthracyclines, immunotherapy) and radiotherapy (RT). CVD and BC have common risk factors (RF), which are related to aging, traditional and cardiometabolic RFs (obesity, dyslipidemia, consumption of alcoholic beverages), and others associated with sex and reproductive women's age, such as early menarche, late menopause, nulliparity, use of oral contraceptives, as well as hormone replacement therapy in postmenopause. Risk stratification and the promotion of an ideal state of cardiovascular (CV) health are fundamental in preventing CVD in survivors. Therapeutic management and follow-up of patients with BC require a multidisciplinary team to reduce complications and mortality of CV origin.

Abstract Background Garlic is an herbal medicinal plant with several pharmacological properties used for the management of various ailments. However, its potential in the reversal of ischemic heart disease induced by combined oral contraceptive pills is not well reported. Objective This study investigated the cardioprotective potential of aqueous garlic extract against cardiotoxicity induced by oral contraceptive pills. Methods Forty-six rats were used for this study. Six were used to determine the lethal dose (LD50), and 40 rats were divided randomly into 5 groups of 8 rats each. Group A received feed and distilled water. Group B received 0.6 mg/kg of oral contraceptive pills. Group C received 500 mg/kg of garlic extract. Group D received 0.6 mg/kg of oral contraceptive pills + 500 mg/kg garlic extract. Group E received 0.6 mg/kg of oral contraceptive pills + 700 mg/kg garlic extract. The animals were sacrificed, and blood and tissue samples were collected for biochemical and histological analysis. Statistical analysis was done using SPSS, and p values < 0.05 were considered significant. Results The acute toxicity dose of combined oral contraceptive pills was 1.5 mg/kg for albino rats. Combined oral contraceptive pills induced ischemic necrosis as revealed by the photomicrographs, in addition to elevation of serum cardiac troponin-1, lactate dehydrogenase, creatine kinase, and malondialdehyde levels. Treatment with garlic extract demonstrated significant reduction in cardiac troponin-1 (p = 0.000), lactate dehydrogenase (p = 0.002), creatine kinase (p = 0.001), and malondialdehyde (p = 0.001) levels, as well as restoration of the cardiac cytoarchitecture changes caused by the combined oral contraceptive pills. Conclusion This study has demonstrated that aqueous garlic juice can reverse ischemic heart disease, lessen cytoarchitectural alterations of the heart caused by combined oral contraceptive pills, and thus ameliorate cardiac dysfunction. ailments However reported Fortysix Forty six LD50, LD50 LD , (LD50) 4 each water 06 0 6 0. mgkg mg kg 50 70 sacrificed SPSS 005 05 0.0 15 1 1. photomicrographs troponin1, troponin1 troponin 1, levels troponin- 0.000, 0000 0.000 000 0.000) 0.002, 0002 0.002 002 0.002) 0.001, 0001 0.001 001 dysfunction LD5 (LD50 7 00 0.00 (LD5 (LD

Abstract Introduction: Metabolic syndrome (MS) and obesity are risk factors for cardiovascular diseases (CVD). However, the development of cardiovascular pathologies in obese individuals without MS is being investigated. Objective: To investigate whether there are similar electrocardiographic (ECG) and echocardiographic changes in individuals with obesity with and without MS. Methodology: A retrospective, descriptive cross-sectional study was carried out with obese patients at a university hospital in Belém, Pará, Brazil. Anthropometric, laboratory, ECG and echocardiographic data were evaluated in both populations. The chi-square test was used to describe the relationship between variables among groups; hypothesis tests with p < 0.05 were considered statistically significant values. Results: The study evaluated 100 individuals with obesity, 60 of whom had MS. The average age was 54 years, and the female sex was prevalent. Systolic blood pressure, HDL, and waist circumference were altered in both groups. Systemic arterial hypertension and low HDL demonstrated 4.27 times and 3.32 times greater likelihood of presenting changes in the ECG and echocardiogram for both groups. On the ECG, diffuse changes in ventricular repolarization were observed in both groups. On echocardiography, left ventricular diastolic dysfunction and left ventricular hypertrophy were present in both populations studied. Conclusion: Obese individuals without MS present a similar risk, requiring adequate attention to their cardiac health. Introduction (MS CVD. CVD .
