The mechanism involved in the pathophysiology of the disease and its possible etiologies are important objects of study due to their impact on the morbidity and mortality of affected patients. Objectives : The aim of this study was to systematically review MINOCA and its characteristics, with emphasis on the clinical profile of patients, etiology, pathophysiology, diagnosis, and treatment of the syndrome. Methods : Relevant articles related to MINOCA were analyzed in the PubMed and LILACS databases. In the initial search stage, 619 eligible articles were obtained, with final inclusion criteria being: original systematic reviews with clinical, epidemiological, diagnostic, or treatment data on MINOCA, published in Portuguese or English, with an abstract, and a publication date limit of September 2020. Results : A total of 10 articles classified as systematic reviews that considered clinical data on MINOCA were included in this review. Conclusion : After analyzing various literature, the present study provided a tool to better understand MINOCA, not only regarding its casuistry but also in grouping parameters and information that contribute to a healthy approach to this clinical situation. It was possible to identify and better outline the clinical profile of patients who presented this condition and the use of appropriate tools for correct diagnosis and ideal treatment.","PeriodicalId":32690,"journal":{"name":"International Journal of Cardiovascular Sciences","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86653303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2017, 12% of deaths caused by infarction in Brazil occurred in the state of Rio de Janeiro, characterizing it as an important “hotspot” in the country. Objectives : This study aimed to characterize the population affected by AMI over the past decade within the state so as to guide future public policies related to CVDs. Methods : Secondary data of patients affected by AMI between 2010 and 2019 were obtained by DATASUS. In-hospital case-fatality rates, mortality rates, and proportional mortality were calculated using information gathered by the Mortality Information System (SIM) and demographic statistics produced by the Brazilian Institute of Geography and Statistics (IBGE). Results : The main results showed that in-hospital case-fatality rates were higher in women, patients aged 60 years and over, the black color/race, and the state's Northwest region. The mortality rate was higher among men, especially in the South-central region and those over 50 years of age. People aged 40-49 years presented a considerable risk of death by infarction. The major categories of data classified as “ignored” in hospital admissions and death certificates were those related to race and education level. Conclusions : Prevention should not only focus on the elderly, but also on people over 40, especially men. The incompleteness of electronic public data systems can affect the use of race/color or education level as epidemiological variables. New studies should be conducted to understand why the South-central region is so heavily affected by infarction.","PeriodicalId":32690,"journal":{"name":"International Journal of Cardiovascular Sciences","volume":"57 7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80117533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives : To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA 2 DS 2 VASC) and bleeding (HASBLED) risk scores. Methods : Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results : This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15 . 417; p<0.001), age of 65 years or older (χ2=14 . 584; p<0.001), and anticoagulation (χ2=5 . 715; p<0.01) were associated with AF. The median CHA 2 DS 2 VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion : The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials.","PeriodicalId":32690,"journal":{"name":"International Journal of Cardiovascular Sciences","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76080643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A better understanding of the correlation between monocyte subsets and inflammatory signaling in patients with atherosclerotic disease in acute coronary syndrome (ACS) is essential for the development of more effective therapies for the prevention and treatment of cardiovascular diseases. Objective: To analyze differences between biomarkers and monocyte activation in the setting of ischemic heart disease. Methods: This was a case-control study comparing biomarkers and monocyte subsets between patients with ACS with and without ST-segment elevation and individuals without coronary stenosis. The nonparametric Kruskal-Wallis test was used to assess differences between groups, and Dunn’s post hoc test was used to identify which groups were different. Cuzick’s test for ordered group trends was used to assess falling or rising trends. Participants were classified into 3 groups: control (0); non-ST-elevation myocardial infarction (NSTEMI) (1); ST-elevation myocardial infarction (STEMI) D1 (2). Results: Forty-seven patients with ACS and 19 controls with no obstructive lesions on coronary angiography were recruited. Monocyte profile assessment was statistically different regarding time of symptom onset and the presence or absence of atherosclerotic disease (Kruskal-Wallis, p = 0.0009). Dunn’s post hoc test showed a significant difference between the control group and the STEMI D1 (p = 0.0014), STEMI D3 (p = 0.0036), and STEMI D7 (p = 0.0195) groups, corresponding to a 2-fold increase in classical (p = 0.0022) and nonclassical (p = 0.0031) monocytes compared with controls. For classical monocytes, there was a difference between the control group and all STEMI groups and between the NSTEMI group and the STEMI D1, D3, and D7 groups. For nonclassical monocytes, there was a difference between the control group and the STEMI D7 group (p = 0.0056) and between the NSTEMI group and the STEMI D7 group (p = 0.0166). Conclusion: This study found that there was an increase in total and classical monocyte mobilization at the time of acute myocardial infarction in patients with ACS.","PeriodicalId":32690,"journal":{"name":"International Journal of Cardiovascular Sciences","volume":"282 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83430348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives : To evaluate the need for an ECG in evaluating children and adolescents before starting physical activities. Methods : We recruited 983 children and adolescents who practiced physical activities for anthropometric assessment, clinical examination and conventional ECG at rest. Variables were analysed using the Goodman test with a significance level of 5%. Results : Participants had a higher incidence of overweight, obesity and severe obesity compared to standard World Health Organization (WHO) values. The most common finding in clinical examination was heart murmur (18.5% of participants).

Objectives The present study assessed the hypothesis that the use of local dental anesthesia with 2% lidocaine with 1:100,000 epinephrine or without a vasoconstrictor can be safe in selected ICD and CCh patients, not resulting in life-threatening events (LTE). Methods Restorative dental treatment under local dental anesthesia was made in two sessions, with a wash-out period of 7 days (cross-over trial), conducting with a 28h - Holter monitoring, and 12-lead electrocardiography, digital sphygmomanometry, and anxiety scale assessments in 3 time periods. Statistical analysis carried out the paired Student’s t test and the Wilcoxon signed-rank test. In all cases, a significance level of 5% was adopted. All patients were in stable condition with no recent events before dental care. Results Twenty-four consecutive procedures were performed in 12 patients (9 women, 3 men) with CCh and ICD: 7 (58.3%) had long QT syndrome (LQTS), 4 (33.3%) Brugada syndrome (BrS), and 1 (8.3%) Catecholaminergic polymorphic ventricular tachycardia (CPVT). Holter analysis showed no increased heart rate (HR) or sustained arrhythmias. Blood pressure (BP), electrocardiographic changes and anxiety measurement showed no statistically significant differences. No LTE occurred during dental treatment, regardless of the type of anesthesia. Conclusion Lidocaine administration, with or without epinephrine, can be safely used in selected CCh-ICD patients without LTE.

One of the main comorbidities associated with complicated forms of the disease is systemic arterial hypertension (SAH). Objective To assess aspects of the clinical, demographic, laboratory, and radiological characteristics of hypertensive patients with COVID-19 to contribute to the knowledge of the relationship between the presence of this comorbidity and the severity of the disease. Methods A total of 380 patients with a diagnosis of acute SARS-CoV-2 infection hospitalized between June and August 2020 were included.
