Background: The use of radial access in cardiac interventions is associated with reduced vascular complications, however it demands a longer learning curve and may increase fluoroscopy time. This study aimed to evaluate the fluoroscopy time as a surrogate marker of radiation exposure, during diagnostic cardiac catheterization by radial and femoral routes. Methods: Retrospective observational study including patients who underwent cardiac catheterization from July 2013 to October 2014. Radial and femoral groups were compared for total procedural time, fluoroscopy time, fluoroscopy to procedural time ratio and vascular complications. Results: The study included 1,915 procedures, 11.2% of which performed by radial approach and 88.8%, by femoral approach. A male prevalence was found in the radial group (80% vs. 54.1%, p < 0.01), but age (61.6 ± 9.7 years vs. 62.4 ± 11.6 years, p = 0.13), total procedural time (8.7 ± 3.8 vs. 8.1 ± 4.1 minutes, p = 0.91), fluoroscopy time (4.8 ± 2.7 vs. 4.1 ± 2.6 minutes, p = 0.89), fluoroscopy/ procedure time ratio (0.56 ± 0.24 vs. 0.49 ± 0.32, p = 0.89), and major complications (0.0% vs. 0.3%, p = 0.55) were similar between groups. Conclusions: The use of the transradial approach for diagnostic procedures by experienced operating physicians may be used with an acceptable total procedural time without increasing the radiation exposure of the patient and staff, and with a low incidence of complications.
Introdução: O coronavírus (COVID-19) possui características desconhecidas, com alta disseminação e letalidade. Nesse contexto, medidas de contenção e distanciamento foram impostas para diminuir a rápida velocidade de transmissão da doença e retardar o colapso do sistema de saúde. Objetivos: Analisar os impactos da pandemia causada pela COVID-19 através da avaliação da saúde mental dos estudantes de medicina, com foco na investigação da ansiedade e depressão. Métodos: Foram coletados dados entre os estudantes das Faculdades de Medicina do Espírito Santo, no período de 18/04 a 03/05/2020, mediante um formulário anônimo de autopreenchimento online, composto de três seções: dados sociodemográficos e informações sobre o coronavírus; escala Hospital Anxiety and Depression Scale (HAD); comportamento e habilidades durante o distanciamento social. Resultados: A amostra final compreendeu 476 pessoas, 70,2% do sexo feminino e 29,1% de sexo masculino, com predomínio de 59,7% na faixa etária de 21 a 25 anos. De acordo com a escala HAD, 7,1% apresentaram provável quadro de depressão e 36,1% ansiedade. O aumento do consumo de álcool e outras drogas foi relatado por 46,8% dos entrevistados, e 6,1% afirmam terem considerado fazer mal a si mesmos. Conclusão: O distanciamento social pode contribuir para o desencadeamento ou intensificação dos transtornos depressivos, ansiosos e aumento no consumo de álcool e outras drogas. Assim, medidas preventivas e de apoio, durante períodos de pandemias, se tornam necessárias para evitar o adoecimento do estudante de medicina e futuro profissional.
Background Approaching the congestive patient is a complex task that requires the combination of different assessment methods. The Strauss formula uses variations in haemoglobin and haematocrit to estimate plasma volume variations (PVV) and haemoconcentration. However, this formula was only validated in outpatients followed with chronic heart failure. We aimed to assess the applicability of this formula to hospitalized patients for acute heart failure (AHF). Methods We conducted a single-centre, retrospective, observational study of 302 patients who were admitted to our hospital for AHF during 2016 and were discharged alive. Baseline clinical, laboratory and demographic characteristics were evaluated at admission and the Strauss formula was applied, as PVV (%) = 100 x [(Hb A / Hb D) x (1 − Hct D) / (1 − Hct A)] − 100), where A = admission and D = discharge. At discharge, we considered that a positive change (≥0%) in PV regarding the admission was linked to an increase in PV (haemodilution); a negative change (<0%) correlated to a decrease in the PV (haemoconcentration). The primary endpoint was a composite of cardiovascular death (CV-death) and HF readmission at 3-months. Results Mean age was 76±11 years and 57% were male. At baseline, 92% were on clinical-haemodynamic profile B, with a median NT-proBNP of 2157 (IQR 1161–4242) pg/dL, a mean of glomerular filtration rate (GFR) of 63±57 mL/min/m2, a mean haemoglobin of 12±2 g/dL and a mean haematocrit of 38±6%. At discharge, the median plasma volume variation was −1.1% (IQR – 9.6 to 7.8) and the distribution of PVV values in the histogram reveals that a large proportion of patients (44%) increased or maintained plasma volume (PVV ≥0% – haemodilution). The group of patients who decreased plasma volume at discharge was slightly younger (75 vs 78 years, p=0.044), showing higher numerical decreases in NT-proBNP, gamma-glutamyl transferase (gGT) and bilirubin at discharge. A positive change in PV (PVV >0%) during admission almost doubled the risk for readmission and CV-death at 3-months [OR 1.9 (95% CI: 1.1 to 3.1, p=0.026], after adjusting for age and sex. Conclusions In this work, we demonstrate that PVV, as calculated by the Strauss formula, increases or is unchanged in 44% of patients admitted with AHF and is strongly associated with a composite of 3-months CV death and HF readmission. Tools to guide the management of residual congestion are of great importance to assess the optimal discharge timing. Funding Acknowledgement Type of funding source: None
Introduction Patients with persistent chest discomfort or other symptoms suggestive of ischaemia and ST segment elevation in two contiguous leads on electrocardiography should be prompt managed to revascularization and emergent angiography for percutaneous intervention in two hours is the preferred reperfusion strategy. Purpose Our aim is to show the importance of differential diagnosis in a patient with an initial diagnosis of ST segment elevation myocardial infarction (STEMI). Clinical case We present a case of 67 years old women with a past medical history of dyslipidemia and polymyalgia rheumatica, treated with rosuvastatin 10mg id and prednisolone 5 mg id. The patient was admitted to emergency department complaining of chest pain with 3 hours of evolution that started after a period of nausea and vomiting. Physical examination showed slight tachypnea with 22 breath per minute, blood pressure 93/40 mmHg, heart rate 110 beats per minute, oxygen saturation in room air 90%, heart sounds with a systolic murmur II/VI and lung crackles in inferior lobes, with no peripheral oedema. Electrocardiography showed sinus rhythm and ST segment elevation in DI, DII and V2-6. Patient was treated with aspirin 300mg, ticagrelor 180mg, furosemide 40mg, oxygen therapy and was scheduled for emergent coronariography. This procedure revealed no significant coronary lesions and ventriculography identified apical ballooning, diagnosing takotsubo myocardiopathy. Clinical condition starts to deteriorate, and an echocardiography identified akinetic apical and midventricular segments and hyperkinetic basal segments with systolic anterior motion of mitral valve, significant mitral regurgitation and left ventricular outflow tract obstruction (LVOTO) with an intraventricular gradient superior to 60 mmHg. Adequate hemodynamic monitoring and heart rate control allowed a substantial clinical improvement. Two days later a cardiac magnetic ressonance was done, confirmed the diagnosis and identified an apical thrombus. The patient was later discharged stable with oral hypocoagulation with anti-vitamin K antagonist. Discussion and Conclusion Takotsubo cardiomyopathy is a unique cardiac syndrome characterized by transient systolic dysfunction witch often mimics acute coronary syndromes (ACS). After exclusion of an ACS, echocardiography is of primordial importance in the assessment of these patients. Left heart failure with pulmonar oedema, mitral regurgitation, LVOTO and thrombus formation were all complications that were present in this clinical case and established the indication to proper therapeutic attitudes.
