A Coronary Artery Anomaly Presenting as Acute Coronary Syndrome: A Case Report.

BACKGROUND Coronary artery anomalies (CAAs) are rare congenital malformations with different clinical presentations and pathophysiological mechanisms. These anomalies are frequently the cause of sudden death in young patients. Most CAAs are incidental findings owing to the lack of symptoms; however, they may be associated with acute coronary syndrome in rare cases. CASE REPORT We describe the case of a 47-year-old man who presented with a 1-day history of progressive typical chest pain and elevated troponin levels. The patient underwent a coronary angiography, which unveiled the anomalous origin of the left main coronary artery arising from the right coronary artery, with an interarterial course between the ascending aorta and the pulmonary artery, without coronary artery disease. Coronary computed tomography angiography confirmed the CAA and its relationship with the symptoms. An uneventful coronary artery bypass graft was undertaken, and at the 1-year follow-up, the patient was asymptomatic, with a normal stress test. CONCLUSIONS This case depicts the presentation of atypical acute coronary syndrome in a young patient with a rare CAA. In such patients, coronary angiography and coronary computed tomography angiography are essential tools to confirm the diagnosis and to determine treatment. Although controversial, in young individuals presenting CAA with an interarterial course, such as the left main coronary artery arising from the right coronary artery, coronary artery bypass graft may be an important treatment option to avoid sudden death in the future.

Safe and effective protocol for discharge 3 days after cardiac surgery.

The Enhanced Recovery After Surgery (ERAS) protocol affected traditional cardiac surgery processes and COVID-19 is expected to accelerate its scalability. The aim of this study was to assess the impact of an ERAS-based protocol on the length of hospital stay after cardiac surgery. From January 2019 to June 2020, 664 patients underwent consecutive cardiac surgery at a Latin American center. Here, 46 patients were prepared for a rapid recovery through a multidisciplinary institutional protocol based on the ERAS concept, the "TotalCor protocol". After the propensity score matching, 46 patients from the entire population were adjusted for 12 variables. Patients operated on the TotalCor protocol had reduced intensive care unit time (P < 0.025), postoperative stay (P ≤ 0.001) and length of hospital stay (P ≤ 0.001). In addition, there were no significant differences in the occurrence of complications and death between the two groups. Of the 10-central metrics of TotalCor protocol, 6 had > 70% adherences. In conclusion, the TotalCor protocol was safe and effective for a 3-day discharge after cardiac surgery. Postoperative atrial fibrillation and renal failure were predictors of postoperative stay > 5 days.

Acute Myocarditis Associated with Acute Myocardial Infarction.

Concomitant acute myocarditis and acute coronary thrombosis is a rare presentation of acute chest pain in the emergency department, although the association between acute infections with a variety of pathogens and an increased risk of myocardial infarction has been reported. A case of acute myocardial infarction associated with acute myocarditis caused by coronavirus 229E in a middle-aged man without risk factors for coronary artery disease is described here. Coronary CT angiography with late enhancement protocol revealed areas of myocarditis and infarction, and cardiac MRI and coronary angiography were then performed. © RSNA, 2021.

Clinical outcomes and need for intensive care after non-ST-segment-elevation myocardial infarction.

BACKGROUND: The decision on whether non-ST-segment elevation myocardial infarction (NSTEMI) patients should be admitted to intensive care units (ICU) takes into account several factors including hospital routines. The Acute Coronary Treatment and Intervention Outcomes Network (ACTION) ICU score was developed to predict complications requiring ICU care post-NSTEMI. METHODS: We described patient characteristics and clinical outcomes of 1263 NSTEMI patients admitted to a private hospital in Sao Paulo, Brazil, from 2014 to 2018. We also aimed to retrospectively identify NSTEMI patients who might not have needed to be admitted to the ICU based on the ACTION ICU risk score. We defined complications requiring ICU care post-NSTEMI as cardiac arrest, cardiogenic shock, stroke, re-infarction, death, heart block requiring pacemaker placement, respiratory failure, or sepsis. RESULTS: Mean age was 62.3 years and 35.8% were female. A total of 94.6% of NSTEMI patients were admitted to the ICU. Most NSTEMI patients (91.9%) underwent coronary angiography. Percutaneous coronary intervention was performed in 47.1% and coronary artery bypass graft surgery in 10.3%. Complications requiring ICU care occurred in 62 patients (4.9%). In-hospital mortality rate was 1.3%. Overall, 70.4% had an ACTION ICU score ≤ 5. The C-statistics for the ACTION risk score to predict complications was 0.55 (95% confidence interval 0.47-0.63). CONCLUSIONS: Complications requiring ICU care were infrequent in a cohort of NSTEMI patients who were routinely admitted to the ICU over a 4-year period. The ACTION risk score had low accuracy in the prediction of complications requiring ICU care in our population.

COVID-19-Related Restrictions and Quarantine COVID-19: Effects on Cardiovascular and Yo-Yo Test Performance in Professional Soccer Players.

The present study aimed to verify the quarantine's effects during a serious viral outbreak on the cardiovascular and performance associated with the Yo-Yo test in a sample of professional soccer players. 20 high-level soccer players (n = 20; age: 26 ± 4 years-old; weight: 76.85 ± 6.7 kg; height: 179 ± 6 cm) participated in this study. The intermittent Yo-Yo test was performed pre- and post- COVID-19 quarantine in a random order. During each test, the soccer players' running performance outcomes were monitored using a portable 5-Hz GPS with a 100 Hz accelerometer and a paired t-test was conducted at a p-value of ≤ 0.05. The main results demonstrated significant differences between pre- versus post-COVID-19 quarantine in the following variables: relative distance (161.7 ± 5.9 > 141.1 ± 33.8 m/min), maximal speed (18.7 ± 0.9 > 18.2 ± 0.6 km/h), acceleration (60 ± 20 frequency > 52 ± 16 frequency), deceleration (34 ± 13 frequency > 27 ± 6 frequency), sprints > 19 km/h [0.8 (0.2;3)% >0.5 (0;0.5)%], and in high intensity running distance [16.48 (2.68;41.64)m > 0.827 (0.164;3.0)m]. We concluded that COVID-19-related restrictions and quarantine COVID-19 demonstrated adverse effects on professional soccer players' Yo-Yo tests performance.

Cardiomiopatia periparto associada à síndrome do QT longo e síncope por taquicardia ventricular polimórfica: relato de caso / Peripartum cardiomyopathy associated with long QT syndrome and polymorphic ventricular tachycardia syncope: a case report

A cardiomiopatia periparto é uma causa rara de insuficiência cardíaca no período entre o último mês de gestação e os cinco meses após o parto. A síndrome do QT longo caracteriza-se pelo atraso da repolarização ventricular e pode se manifestar com síncope e morte súbita devido a um tipo de taquicardia ventricular polimórfica conhecida como torsades de pointes. Descrição do caso: J.S., 26 anos, sexo feminino, natural e procedente de São Paulo. Paciente puérpera - 40º dia (G3P3A0), procurou o pronto-socorro com queixa de síncope durante amamentação e dispneia em moderados esforços. Durante a avaliação no PS, evoluiu para desconforto torácico e agitação psicomotora, sendo notada taquicardia ventricular não sustentada no monitor cardíaco ( torsades de pointes), que foi controlada com cardioversão elétrica e sulfato de magnésio intravenoso. O eletrocardiograma mostrou ritmo sinusal, alteração difusa da repolarização ventricular e intervalo QTc de 580 ms. O ecocardiograma mostrou disfunção sistólica moderada, com fração de ejeção do ventrículo esquerdo de 43% à custa de hipocinesia difusa. Após avaliação da equipe de arritmologia chegou-se ao diagnóstico de cardiomiopatia periparto associado à síndrome do QT longo. Foi iniciado tratamento otimizado para insuficiência cardíaca e implantado cardiodesfibrilador por causa de episódios recorrentes de arritmia durante a internação. Discussão: A cardiomiopatia periparto é uma doença rara, porém, tem taxa de mortalidade elevada, entre 18% e 56%. A paciente descrita satisfez os quatro critérios para o diagnóstico: sintomas de insuficiência cardíaca nos primeiros 5 meses depois do parto, ausência de cardiomiopatia prévia, etiologia desconhecida e disfunção sistólica com FEVE < 45%. A síndrome do QT longo é uma doença genética de apresentações variáveis. Os fatores que desencadeiam as taquiarritmias são situações de instabilidade elétrica por hiperatividade do sistema simpático e também situações raras, como a cardiomiopatia periparto. Em casos de arritmias ventriculares graves, o tratamento é o implante de cardiodesfibrilador. Conclusão: A associação da cardiomiopatia periparto com a síndrome do QT longo é rara. A gravidade associada a essas condições torna importante o diagnóstico precoce e tratamento imediato pelo potencial risco de morte associado a ambas as condições clínicas

Peripartum cardiomyopathy is a rare cause of heart failure during the period between the last month of pregnancy and five months after delivery. Long QT syndrome is characterized by a delay in ventricular repolarization and may manifest with syncope and sudden death due to a type of polymorphic ventricular tachycardia known as torsades de pointes. Case description: J.S., 26-years-old, female, born and residing in São Paulo, Puerperal - 40th day (G3C3A0), went to the emergency room complaining of syncope during breastfeeding and dyspnea on moderate exertion. During evaluation in the ER, the patient developed thoracic discomfort and psychomotor agitation, with non-sustained ventricular tachycardia on the cardiac monitor (torsades de pointes), which was controlled with electrical cardioversion and intravenous magnesium sulfate. The electrocardiogram showed sinus rhythm, diffuse alteration of ventricular repolarization and QTc interval of 580 ms. The echocardiogram showed moderate systolic dysfunction, with a left ventricular ejection fraction of 43% influenced by diffuse hypokinesia. After evaluation by the arrhythmology team, the diagnosis of peripartum cardiomyopathy associated with long QT syndrome was made. Optimized treatment for heart failure was initiated and a cardioverter-defibrillator was implanted due to recurrent episodes of arrhythmia during hospitalization. Discussion: Peripartum cardiomyopathy is a rare disease, but it has a high mortality rate, between 18% and 56%. The patient described met the 4 diagnostic criteria: symptoms of heart failure in the first 5 months after delivery, absence of prior cardiomyopathy, unknown etiology, and systolic dysfunction with LVEF<45%. Long QT syndrome is a genetic disease of varying presentations. The factors that trigger the tachyarrhythmias are situations of electrical instability due to sympathetic system hyperactivity and rare situations, such as peripartum cardiomyopathy. In cases of severe ventricular arrhythmias, the treatment is a cardioverter-defibrillator implant. Conclusion: The association of peripartum cardiomyopathy with long QT syndrome is rare. The severity associated with these conditions points out early diagnosis and immediate treatment important because of the potential risk of death associated with both clinical conditions

Impact of Chest Pain Protocol with Access to Telemedicine on Implementation of Pharmacoinvasive Strategy in a Private Hospital Network.

BACKGROUND: Brazilian registries have shown a gap between evidence-based therapies and real treatments. We aim to compare the use of the pharmacoinvasive strategy and mortality in patients with ST elevation myocardial infarction (STEMI) transferred pre- and post-chest pain protocol with access to telemedicine (CPPT) in a private hospital network. MATERIALS AND METHODS: A CPPT was implemented in 22 private emergency departments in 2012. Emergency physicians and nurses of all facilities were trained to disseminate the information to comply with a chest pain protocol focusing on reperfusion therapy (pharmacoinvasive strategy) for STEMI. To conduct clinical discussions using telemedicine, a cardiologist from a reference hospital in cardiology (RHC) was available 24 h/day, 7 days/week. Using the database of all consecutive admissions, we compared the data of patients with STEMI transferred to the RHC in 2011 (pre-CPPT) and 2013-2014 (post-CPPT). RESULTS: We included 376 patients (113 pre-CPPT and 263 post-CPPT) with STEMI. All patients admitted in the RHC were transferred from the 22 emergency departments. Comparing pre-CPPT and post-CPPT, we did not find differences regarding age, gender, hypertension, dyslipidemia, diabetes, smoking, previous myocardial infarction, or Killip classification. However, the use of CPPT was associated with a greater use of pharmacoinvasive strategy (55.8% versus 38%; p = 0.002) and a trend toward lower in-hospital mortality (3% versus 8%; p = 0.06). CONCLUSIONS: The implementation of a CPPT was associated with a significant increase in the use of pharmacoinvasive strategy in patients with STEMI and a trend toward reduced in-hospital mortality in a private hospital network.

Comparação de critérios diagnósticos de insuficiência renal aguda em cirurgia cardíaca / Comparison of diagnostic criteria for acute kidney injury in cardiac surgery

FUNDAMENTO: Há grande controvérsia quanto ao diagnóstico de Insuficiência Renal Aguda (IRA), existindo mais de 30 diferentes definições. OBJETIVO: Avaliar a incidência e os fatores de risco para desenvolvimento de IRA no pós-operatório de cirurgia cardíaca de acordo com os critérios RIFLE, AKIN e KDIGO, e comparar o poder prognóstico desses critérios. MÉTODOS: Estudo de corte transversal que incluiu 321 pacientes (62 [53 - 71] anos, 140 homens) consecutivamente submetidos a cirurgia cardíaca entre junho de 2011 e janeiro de 2012. Os pacientes foram acompanhados por 30 dias, com vistas ao desenvolvimento de um desfecho composto (mortalidade, necessidade de diálise e internação prolongada). RESULTADOS: A incidência de IRA variou de 15% - 51%, conforme o critério diagnóstico adotado. Enquanto a idade se associou ao risco de IRA nos três critérios, houve variação nos demais determinantes. Durante o acompanhamento, 89 pacientes apresentaram o desfecho e todos os critérios se associaram ao risco aumentado na análise Cox univariada e após o ajuste para idade, sexo, diabetes e tipo de cirurgia. Contudo, após novo ajuste para tempo de circulação extracorpórea e presença de baixo débito cardíaco, apenas o diagnóstico de IRA pelo critério KDIGO manteve esta associação significativa (HR= 1,89 [95% IC: 1,18 - 3,06]). CONCLUSÕES: A incidência e os fatores de risco para IRA pós-cirurgia cardíaca têm grande variação de acordo com os critérios diagnósticos utilizados. Em nossa análise, o critério KDIGO se mostrou superior ao AKIN e ao RIFLE quanto ao seu poder prognóstico.

BACKGROUND: There is considerable controversy regarding the diagnosis of Acute Kidney Injury (AKI), and there are over 30 different definitions. OBJECTIVE: To evaluate the incidence and risk factors for the development of AKI following cardiac surgery according to the RIFLE, AKIN and KDIGO criteria, and compare the prognostic power of these criteria. METHODS: Cross-sectional study that included 321 consecutively patients (median age 62 [53-71] years; 140 men) undergoing cardiac surgery between June 2011 and January 2012. The patients were followed for up to 30 days, for a composite outcome (mortality, need for dialysis and extended hospitalization). RESULTS: The incidence of AKI ranged from 15% - 51%, accordingly to the diagnostic criterion adopted. While age was associated with risk of AKI in the three criteria, there were variations in the remaining risk factors. During follow-up, 89 patients developed the outcome and all criteria were associated with increased risk in the univariate Cox analysis and after adjustment for age, gender, diabetes, and type of surgery. However, after further adjustment for extracorporeal circulation and the presence of low cardiac output, only AKI diagnosed by the KDIGO criterion maintained this significant association (HR= 1.89 [95% CI: 1.18 - 3.06]). CONCLUSION: The incidence and risk factors for AKI after cardiac surgery vary significantly according to the diagnostic criteria used. In our analysis, AKI the KDIGO criterion was superior to AKIN and RIFLE with regard its prognostic power.

Vocal effort and voice handicap among teachers.

The relationship between voice handicap and professional vocal effort was investigated among teachers in a cross-sectional study of census nature on 4496 teachers within the public elementary education network in Salvador, Bahia, Brazil. Voice handicap (the outcome of interest) was evaluated using the Voice Handicap Index 10. The main exposure, the lifetime vocal effort index, was obtained as the product of the number of years working as a teacher multiplied by the mean weekly working hours. The prevalence of voice handicap was 28.8% among teachers with high professional vocal effort and 21.3% among those with acceptable vocal effort, thus yielding a crude prevalence ratio (PR) of 1.36 (95% confidence interval [CI]=1.14-1.61). In the final logistic model, the prevalence of voice handicap was statistically associated with the professional vocal effort index (PR=1.47; 95% CI=1.19-1.82), adjusted according to sex, microphone availability in the classroom, excessive noise, pressure from the school management, heartburn, and rhinitis.

Intrathecal cytokines in spinal cord schistosomiasis.

We investigate the cytokine profile in the cerebrospinal fluid (CSF) and serum of patients with spinal cord schistosomiasis (SCS). Increased levels of IL-1beta, IL-4, IL-6 and IL-10 and low concentrations of TNF-alpha and IFN-gamma were observed in both CSF and serum. CSF showed higher levels of IL-4 and IL-6 when compared to the paired serum samples. A negative correlation between the concentrations of IL-10 and IFN-gamma was observed in the CSF. These findings suggest an inflammatory as well as a skewed type-2 immune response that probably occur both locally and systemically and may be involved in the pathogenesis of SCS.

Hipertireoidismo manifestando-se como febre de origem indeterminada / Hyperthyroidism presenting as fever of unknowm origin

Trata-se de paciente adulta jovem internada no Hospital das Clínicas da Universidade Federal de Minas Gerais (HC/UFMG) para esclarecimento de doença febril de aproximadamente um ano e oito meses de evolução. Ao lado das manifestações constitucionais apresentava alterações cardíacas, hepatesplenomegalia e icterícia. O diagnóstico de hipertireoidismo foi confirmado através da dosagem dos hormônios tireoidianos. Apesar de ter sido considerado como possibilidade diagnóstica na fase inicial da investigação, não se acreditou, de princípio que tal diagnóstico pudesse explicar todas as alterações observadas. Houve regressão progressiva e completa das manifestações clínicas com o tratamento do hipertireoidismo.

Derivaçäo arterial com veia in situ no membro superior / Arterial bypass with vein in situ in arm

A isquemia crônica grave dos membros superiores é rara, devido à menor incidência das doenças arteriais obstrutiva na extremidade superior e a presença de uma rede colateral competente pré-existente. No caso objeto deste relato, um paciente portador de doença auto-imune apresentou necroses digitais mútiplas associadas à oclusäo da artéria braquial. O tratamento constou de pulsoterapia com corticóides, antibioticoterapia específica, ponte braquioradial com a veia cefálica "in situ" e simpatectomia torácicai T²-T5, além de desbridamento das lesöes necróticas. Os estudos anátomo-patológicos foram compatíveis com esclerodermia. A evoluçäo satisfatória a longo prazo nos leva a recomendar esta técnica nas revascularizaçöes dos membros superiores, sobretudo quando coexista a indicaçäo de longas pontes associada a um deságüe reduzido
