Desempenho do Escore SHARPEN e do Índice de Comorbidade de Charlson para Predição de Mortalidade durante a Internação Hospitalar e após a Alta na Endocardite Infecciosa / Performance of the SHARPEN Score and the Charlson Comorbidity Index for In-Hospital and Post-Discharge Mortality Prediction in Infective Endocarditis

Resumo Fundamento O SHARPEN foi o primeiro escore desenvolvido especificamente para a predição de mortalidade hospitalar em pacientes com endocardite infecciosa (EI), independentemente da realização de cirurgia cardíaca. Objetivos Analisar a capacidade do escore SHARPEN na predição de mortalidade hospitalar e mortalidade após a alta e compará-la à do Índice de Comorbidade de Charlson (ICC). Métodos Estudo retrospectivo do tipo coorte incluindo internações por EI (segundo os critérios de Duke modificados) entre 2000 e 2016. A área sob a curva ROC (AUC-ROC) foi calculada para avaliar a capacidade preditiva. Curvas de Kaplan-Meier e regressão de Cox foram realizadas. Um valor de p < 0,05 foi considerado estatisticamente significativo. Resultados Estudamos 179 internações hospitalares. A mortalidade hospitalar foi 22,3%; 68 (38,0%) foram submetidos à cirurgia cardíaca. Os escores SHARPEN e ICC (mediana e intervalo interquartil) foram, respectivamente, 9(7-11) e 3(2-6). O escore SHARPEN mostrou melhor predição de mortalidade hospitalar em comparação ao ICC nos pacientes não operados (AUC-ROC 0,77 vs. 0,62, p = 0,003); não foi observada diferença no grupo total (p=0,26) ou nos pacientes operados (p=0,41). Escore SHARPEN >10 na admissão foi associado a uma menor sobrevida hospitalar no grupo total (HR 3,87; p < 0,001), nos pacientes não operados (HR 3,46; p = 0,006) e de pacientes operados (HR 6,86; p < 0,001) patients. ICC > 3 na admissão foi associada a pior sobrevida hospitalar nos grupos total (HR 3,0; p = 0,002), de pacientes operados (HR 5,57; p = 0,005), mas não nos pacientes não operados (HR 2,13; p = 0,119). A sobrevida após a alta foi pior nos pacientes com SHARPEN > 10 (HR 3,11; p < 0,001) e ICC > 3 (HR 2,63; p < 0,001) na internação; contudo, não houve diferença na capacidade preditiva entre esses grupos. Conclusão O SHARPEN escore foi superior ao ICC na predição de mortalidade hospitalar nos pacientes não operados. Não houve diferença entre os escores quanto à mortalidade após a alta.

Abstract Background SHARPEN was the first dedicated score for in-hospital mortality prediction in infective endocarditis (IE) regardless of cardiac surgery. Objectives To analyze the ability of the SHARPEN score to predict in-hospital and post-discharge mortality and compare it with that of the Charlson comorbidity index (CCI). Methods Retrospective cohort study including definite IE (Duke modified criteria) admissions from 2000 to 2016. The area under the ROC curve (AUC-ROC) was calculated to assess predictive ability. Kaplan-Meier curves and Cox regression was performed. P-value < 0.05 was considered statistically significant. Results We studied 179 hospital admissions. In-hospital mortality was 22.3%; 68 (38.0%) had cardiac surgery. Median (interquartile range, IQR) SHARPEN and CCI scores were 9(7-11) and 3(2-6), respectively. SHARPEN had better in-hospital mortality prediction than CCI in non-operated patients (AUC-ROC 0.77 vs. 0.62, p = 0.003); there was no difference in overall (p = 0.26) and in operated patients (p = 0.41). SHARPEN > 10 at admission was associated with decreased in-hospital survival in the overall (HR 3.87; p < 0.001), in non-operated (HR 3.46; p = 0.006) and operated (HR 6.86; p < 0.001) patients. CCI > 3 at admission was associated with worse in-hospital survival in the overall (HR 3.0; p = 0.002), and in operated patients (HR 5.57; p = 0.005), but not in non-operated patients (HR 2.13; p = 0.119). Post-discharge survival was worse in patients with SHARPEN > 10 (HR 3.11; p < 0.001) and CCI > 3 (HR 2.63; p < 0.001) at admission; however, there was no difference in predictive ability between these groups. Conclusion SHARPEN was superior to CCI in predicting in-hospital mortality in non-operated patients. There was no difference between the scores regarding post-discharge mortality.

Analysis of the SHARPEN Score in the Prediction of In-Hospital Mortality of Patients With Infective Endocarditis Undergoing Cardiac Surgery

Abstract Background The SHARPEN score was developed to predict in-hospital mortality in patients hospitalized for infective endocarditis (IE), undergoing or not undergoing cardiac surgery. A comparison with other available scores has not yet been carried out. Objective To evaluate the performance of the SHARPEN score in predicting in-hospital mortality in patients hospitalized for IE undergoing cardiac surgery and compare it with that of both nonspecific and IE-specific surgical scores. Methods Retrospective cohort study including all admissions of patients ≥18 years who underwent cardiac surgery due to active IE (modified Duke criteria) at a tertiary care university hospital between 2007 and 2016. The SHARPEN score was compared to the EuroSCORE, EuroSCORE II, STS-IE, PALSUSE, AEPEI, EndoSCORE and RISK-E scores. Differences P<0.05 were considered statistically significant. Results A total of 105 hospitalizations of 101 patients (mean age 57.4±14.6 years; 75.2% male) were included. The median SHARPEN score was 11 (9-13) points. The observed in-hospital mortality was 29.5%. There was no statistically significant difference in observed vs. estimated mortality (P = 0.147), with an area under the ROC curve of 0.66 (P = 0.008). In comparison with the other scores, no difference was observed in discriminative ability. The statistics of the SHARPEN score at a cutoff >10 points — positive predictive value (PPV): 38.1%, 95%CI:30.4-46.6; negative predictive value (NPV): 80.0%, 95%CI:69.8-87.4; and accuracy: 58.1%, 95%CI:48.1-67.6 — showed overlapping 95%CIs, indicating no significant difference between scores. Conclusions The SHARPEN score did not present parameters with a significant difference in relation to the other scores analyzed; despite the easy obtainment of its few variables, it has limited applicability in clinical practice, like other existing scores.

Valvuloplasty Without Prosthetic Ring or Band in Patients with Degenerative Mitral Regurgitation: Long-Term Results and Predictive Factors for Outcomes

Abstract Introduction: Mitral valvuloplasty including ring/band support is widely performed despite potential drawbacks of rings. Unsupported valvuloplasty is performed in only a few centers. This study aimed to report long-term outcomes of patients undergoing unsupported valvuloplasty for degenerative mitral regurgitation (MR) and to identify predictive factors for outcomes. Methods: This is a retrospective cohort including patients undergoing mitral valve repair for degenerative MR from 2000 to 2018. The main techniques were Wooler annuloplasty and quadrangular resection. Kaplan-Meier curves and Cox regression models were used for statistical analysis. Results: One hundred fifty-eight patients were included (median age: 64.0 years). In-hospital mortality was 2.5%. Maximum follow-up was 19.6 years, with a median of 4.7 years (992 patient-years). Overall survival at 5, 10, and 15 years was 91.0% (95% confidence interval [CI]: 85.7-96.3), 87.6% (95% CI: 80.7-94.5), and 78.1% (95% CI: 65.9-90.3), respectively. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II was an independent predictor of late death (hazard ratio [HR] 1.42; P=0.016). Freedom from mitral reoperation at 5, 10, and 15 years was 88.1% (95% CI: 82.0-94.2), 82.4% (95% CI: 74.6-90.2), and 75.7% (95% CI: 64.1-87.3), respectively. Left atrial diameter > 56 mm was associated with late reintervention in univariate analysis (HR 1.06; P=0.049). Conclusion: Degenerative MR can be successfully treated with repair techniques without annular support, thus avoiding the technical and logistical drawbacks of ring/band implantation while maintaining good long-term results. EuroSCORE II was a risk factor for late death, and larger left atrium was associated with late reoperation.

Análise de Escores de Risco para Predição de Mortalidade em Pacientes Submetidos à Cirurgia Cardíaca por Endocardite / Analysis of Risk Scores to Predict Mortality in Patients Undergoing Cardiac Surgery for Endocarditis

Resumo Fundamento Escores de risco estão disponíveis para uso na prática clínica diária, mas saber qual deles escolher é ainda incerto. Objetivos Avaliar o EuroSCORE logístico, o EuroSCORE II e os escores específicos para endocardite infecciosa STS-IE, PALSUSE, AEPEI, EndoSCORE e RISK-E na predição de mortalidade hospitalar de pacientes submetidos à cirurgia cardíaca por endocardite ativa em um hospital terciário de ensino do sul do Brasil. Métodos Estudo de coorte retrospectivo incluindo todos os pacientes com idade ≥ 18 anos submetidos à cirurgia cardíaca por endocardite ativa no centro do estudo entre 2007 e 2016. Foram realizadas análises de calibração (razão de mortalidade observada/esperada, O/E) e de discriminação (área sob a curva ROC, ASC), sendo a comparação das ASC realizada pelo teste de DeLong. P < 0,05 foi considerado estatisticamente significativo Resultados Foram incluídos 107 pacientes, sendo a mortalidade hospitalar de 29,0% (IC95%: 20.4-37.6%). A melhor razão de mortalidade O/E foi obtida pelo escore PALSUSE (1,01, IC95%: 0,70-1,42), seguido pelo EuroSCORE logístico (1,3, IC95%: 0,92-1,87). O EuroSCORE logístico apresentou o maior poder discriminatório (ASC 0,77), significativamente superior ao EuroSCORE II (p = 0,03), STS-IE (p = 0,03), PALSUSE (p = 0,03), AEPEI (p = 0,03) e RISK-E (p = 0,02). Conclusões Apesar da disponibilidade dos recentes escores específicos, o EuroSCORE logístico foi o melhor preditor de mortalidade em nossa coorte, considerando-se análise de calibração (mortalidade O/E: 1,3) e de discriminação (ASC 0,77). A validação local dos escores específicos é necessária para uma melhor avaliação do risco cirúrgico. (Arq Bras Cardiol. 2020; 114(3):518-524)

Abstract Background Risk scores are available for use in daily clinical practice, but knowing which one to choose is still fraught with uncertainty. Objectives To assess the logistic EuroSCORE, EuroSCORE II, and the infective endocarditis (IE)-specific scores STS-IE, PALSUSE, AEPEI, EndoSCORE and RISK-E, as predictors of hospital mortality in patients undergoing cardiac surgery for active IE at a tertiary teaching hospital in Southern Brazil. Methods Retrospective cohort study including all patients aged ≥ 18 years who underwent cardiac surgery for active IE at the study facility from 2007-2016. The scores were assessed by calibration evaluation (observed/expected [O/E] mortality ratio) and discrimination (area under the ROC curve [AUC]). Comparison of AUC was performed by the DeLong test. A p < 0.05 was considered statistically significant. Results A total of 107 patients were included. Overall hospital mortality was 29.0% (95%CI: 20.4-37.6%). The best O/E mortality ratio was achieved by the PALSUSE score (1.01, 95%CI: 0.70-1.42), followed by the logistic EuroSCORE (1.3, 95%CI: 0.92-1.87). The logistic EuroSCORE had the highest discriminatory power (AUC 0.77), which was significantly superior to EuroSCORE II (p = 0.03), STS-IE (p = 0.03), PALSUSE (p = 0.03), AEPEI (p = 0.03), and RISK-E (p = 0.02). Conclusions Despite the availability of recent IE-specific scores, and considering the trade-off between the indexes, the logistic EuroSCORE seemed to be the best predictor of mortality risk in our cohort, taking calibration (O/E mortality ratio: 1.3) and discrimination (AUC 0.77) into account. Local validation of IE-specific scores is needed to better assess preoperative surgical risk. (Arq Bras Cardiol. 2020; 114(3):518-524)

SAMe-TT2 R2 Score: a useful tool in oral anticoagulation decision-making for venous thromboembolism patients? / Escore SAMe-TT2 R2: uma ferramenta útil na tomada de decisão de anticoagulação oral para pacientes com tromboembolismo venoso?

Background: The SAMe-TT2R2 score was introduced to identify atrial fibrillation patients with a high risk of not achieving a good time in therapeutic range (TTR) during vitamin K antagonists (VKA) therapy. Objective: The aim of this study was to evaluate this score in venous thromboembolism (VTE) patients. Patients and methods: A retrospective cohort study of patients receiving care at the outpatient anticoagulation clinic of a tertiary care teaching hospital. Patients were classified as having low (score 0-1) or high risk (score ≥2) of not achieving a good TTR. The area under the ROC curve was calculated to assess the ability of the score to predict a TTR ≥ 65%. Adverse event-free survival curves according to the SAMe-TT2 R2 score were calculated by the Kaplan-Meier method and compared by the log-rank test. A p-value < 0.05 was considered statistically significant. Results: We investigated 111 patients during a median follow-up of 2.3 (0.7-6.4) years. Mean age was 54.1 ± 15.7 years and 71 (64.0%) were women. Low- and high-risk groups had similar mean TTR (51.9 vs. 49.6%; p = 0.593). The two groups did not differ significantly in the percentage of patients achieving a TTR ≥ 65% (35.6 vs. 25.8%; p =0.370). The c-statistic was 0.595 (p = 0.113) for TTR ≥ 65%. Adverse event-free survival during anticoagulation was also similar in both groups (p = 0.136).Conclusions: The SAMe-TT2R2 score does not seem to be a useful tool in oral anticoagulation decision-making for patients with VTE and should not be used in this setting

Comparação de escores anatômicos e clínicos na predição de desfechos em intervenções coronárias percutâneas primárias / Comparison of anatomical and clinical scores in predicting outcomes in primary percutaneous coronary intervention

Fundamento: Diferentes escores baseados em variáveis anatômicas e/ou clínicas têm sido desenvolvidos para estratificação de risco em pacientes submetidos à intervenção coronariana percutânea (ICP). Estudos comparando a capacidade desses modelos na predição de eventos cardíacos e cerebrovasculares adversos maiores (ECCAM) em pacientes submetidos à ICP primária são escassos. Objetivo: O objetivo desse estudo foi o de comparar os escores SYNTAX (SS), Clinical SYNTAX (CSS), ACEF e ACEF modificado (ACEF Mod ) na predição de ECCAM em pacientes com infarto agudo do miocárdico com supradesnivelamento do segmento ST (IAMCSST) submetidos à ICP primária. Métodos: Foram analisados 311 pacientes consecutivos com IAMCSST submetidos a ICP primária entre abril/2011 e dezembro/2015. As áreas sob a curva característica de operação do receptor (ROC) foram calculadas para avaliar a habilidade desses escores em predizer ECCAM. O nível de significância adotado em todos os testes foi de 5%. Resultados: Os pacientes apresentaram idade média de 60,2 ± 12,0 anos, 35,4% eram do sexo feminino e 22,5% eram diabéticos. A ocorrência de ECCAM foi observada em 23,8% dos participantes. A área sob a curva ROC foi 0,586 (p = 0,028) para ACEF, 0,616 (p = 0,003) para SS, 0,623 (p = 0,002) para ACEF Mod e 0,658 (p < 0,001) para CSS. Na análise multivariada, apenas SS (p = 0,011) e CSS (p = 0,002) foram preditores independentes de ECCAM. Conclusões: SS e CSS elevados foram preditores independentes de ECCAM. Em nossa coorte de pacientes com IAMCSST submetidos à ICP primária, o SS calculado à cineangiocoronariografia inicial mostrou-se uma ferramenta útil para predizer ECCAM

Background: Different scores based on anatomical and/or clinical features have been developed for risk stratification of patients undergoing percutaneous coronary intervention (PCI). Studies comparing the ability of these different models in predicting major adverse cardiac and cerebrovascular events (MACCE) in patients submitted to primary PCI are limited. Objectives: The aim of this study was to compare the ability of the scores SYNTAX (SS), Clinical SYNTAX (CSS), age, creatinine and ACEF, and modified ACEF (ACEF Mod ) to predict MACCE in patients with ST-elevation myocardial infarction (STEMI) submitted to primary PCI. Methods: We analyzed 311 consecutive patients with STEMI submitted to primary PCI between April/2011 and December/2015. The area under the ROC curve was calculated to evaluate the ability of these scores in predicting MACCE. P-values were considered significant at < 0.05. Results: Mean age of the patients was 60.2 ± 12.0 years, 35.4% were females, and 22.5% had diabetes. MACCE occurred in 23.8% of the patients. The area under the ROC curve was 0.586 (p = 0.028) for ACEF, 0.616 (p = 0.003) for SS, 0.623 (p = 0.002) for ACEF Mod , and 0.658 (p < 0.001) for CSS. In multivariate analysis, only high SS (p = 0.011) and CSS (p = 0.002) were independent predictors of MACCE. Conclusions: High SS and CSS were independent predictors of MACCE. In our cohort of STEMI patients undergoing primary PCI, pure anatomical SS calculated at the baseline coronary angiography was a useful tool to predict MACCE

Uso do escore HAS-BLED em um ambulatório de anticoagulação de um hospital terciário / Use of HAS-BLED score in an anticoagulation outpatient Clinic of a tertiary hospital

Fundamento: O escore HAS-BLED foi desenvolvido para avaliar o risco em um ano de sangramento maior em pacientes com fibrilação atrial (FA) anticoagulados com antagonistas da vitamina K (AVK). Objetivo: O objetivo deste estudo foi avaliar a capacidade do escore HAS-BLED e de seus componentes em predizer sangramento maior em pacientes atendidos em um ambulatório de anticoagulação de um hospital terciário. Métodos: Foi realizado um estudo coorte retrospectivo com pacientes com FA tratados com AVK. Análise de regressão logística foi realizada para avaliar a capacidade de cada componente do escore em predizer sangramento maior. O nível de significância adotado em todos os testes foi de 5%. Resultados: Foram estudados 263 pacientes com média de idade de 71,1 ± 10,5 anos ao longo de um período de tratamento de 237,6 pacientes-ano. A mediana do escore HAS-BLED foi de 2 (1-3). A incidência de sangramento maior foi de 5,7%, sendo mais elevada nos pacientes de alto risco que nos pacientes de baixo risco (9,6 vs. 3,1%; p = 0,052). A área sob a curva ROC foi de 0,70 (p = 0,01). Um ponto de corte ≥ 3 mostrou sensibilidade de 66,7%, especificidade de 62,1%, valor preditivo positivo de 9,6% e valor preditivo negativo de 96,9%. Sobrevida livre de sangramento maior foi menor no grupo de alto risco (p = 0,017). Na análise multivariada, o único preditor independente de sangramento maior entre os componentes do escore foi o uso concomitante de antiplaquetários (OR 5,13, IC95%: 1,55-17,0; p = 0,007). Conclusão: O escore HAS-BLED foi capaz de prever sangramento maior na população de pacientes com FA estudada. Entre os componentes do escore, atenção especial deve ser dada para o uso concomitante de antiplaquetários, que mostrou associação independente. Em pacientes com FA em uso de AVK como terapia anticoagulante, o uso de antiplaquetários deve ser realizado somente naqueles pacientes com avaliação risco-benefício favorável

Background: HAS-BLED s core was developed to assess 1-year major bleeding risk in patients anticoagulated with vitamin K antagonists (VKA) due to atrial fibrillation (AF). Objective: Of this study was to assess the ability of HAS-BLED score and its components to predict major bleeding in patients treated in an anticoagulation outpatient clinic of a tertiary hospital. Methods: A retrospective cohort study on AF patients treated with VKA was conducted. Logistic regression analysis was performed to evaluate the ability of individual score components to predict major bleeding. The significance level adopted in all tests was 5%. Results: We studied 263 patients with a mean age of 71.1 ± 10.5 years over a period of 237.6 patients-year. Median HAS-BLED score was 2 (1-3). The overall incidence of major bleeding was 5.7%, and it was higher among high-risk HAS-BLED score patients than in low risk patients (9.6 vs. 3.1%; p = 0.052). Area under the ROC curve was 0.70 (p = 0.01). Cut-off point ≥ 3 showed sensibility of 66.7%, specificity of 62.1%, positive predictive value of 9.6% and negative predictive value of 96.9%. Major bleeding-free survival was lower in high-risk group (p = 0.017). In multivariate analysis, concurrent antiplatelet use was the only independent predictor of major bleeding among score components (OR 5.13, 95%CI: 1.55-17.0; p = 0.007). Conclusion: HAS-BLED score was able to predict major bleeding in this cohort of AF patients. Among score components, special attention should be given for concomitant antiplatelet use, which was independently associated to this outcome. Antiplatelets in AF patients under VKA anticoagulation should be used in selected patients with favorable risk-benefit assessment

Cardiac surgery in Jehovah's witness patients: experience of a Brazilian Tertiary Hospital

Abstract Introduction: The outcomes of Jehovah's Witness (JW) patients submitted to open heart surgery may vary across countries and communities. The aim of this study was to describe the morbidity and mortality of JW patients undergoing cardiac surgery in a tertiary hospital center in Southern Brazil. Methods: A case-control study was conducted including all JW patients submitted to cardiac surgery from 2008 to 2016. Three consecutive surgical non-JW controls were matched to each selected JW patient. The preoperative risk of death was estimated through the mean EuroSCORE II. Results: We studied 16 JW patients with a mean age of 60.6±12.1 years. The non-JW group included 48 patients with a mean age of 63.3±11.1 years (P=0.416). Isolated coronary artery bypass graft surgery was the most frequent surgery performed in both groups. Median EuroSCORE II was 1.29 (IQR: 0.66-3.08) and 1.43 (IQR: 0.72-2.63), respectively (P=0.988). The mortality tended to be higher in JW patients (18.8% vs. 4.2%, P=0.095), and there was a higher difference between the predicted and observed mortality in JW patients compared with controls (4.1 and 18.8% vs. 2.1 and 4.2%). More JW patients needed hemodialysis in the postoperative period (20.0 vs. 2.1%, P=0.039). Conclusion: We showed a high rate of in-hospital mortality in JW patients submitted to cardiac surgery. The EuroSCORE II may underestimate the surgical risk in these patients.

Aneurysm and dissection in a patient with syphilitic aortitis

ABSTRACT In the antibiotic era, aortic aneurysm is a rare complication of syphilis, what makes the diagnostic assumption even more difficult. Nonetheless, this condition should be suspected in patients with aortic aneurysm. Reports of aortic dissection complicating syphilitic aortitis have been distinctly rare in the literature, and their cause-effect relationship has not been definitely established. In this case report, we present a 62-year-old woman with aortic aneurysm and dissection associated with an unexpected diagnosis of syphilitic aortitis.

SAMe-TT2R2 Score in the Outpatient Anticoagulation Clinic to Predict Time in Therapeutic Range and Adverse Events / Uso do Escore SAMe-TT2R2 em Ambulatório de Anticoagulação para Predição de Tempo na Faixa Terapêutica e de Eventos Adversos

Abstract Background: The SAMe-TT2R2 score was developed to predict which patients on oral anticoagulation with vitamin K antagonists (VKAs) will reach an adequate time in therapeutic range (TTR) (> 65%-70%). Studies have reported a relationship between this score and the occurrence of adverse events. Objective: To describe the TTR according to the score, in addition to relating the score obtained with the occurrence of adverse events in patients with nonvalvular atrial fibrillation (AF) on oral anticoagulation with VKAs. Methods: Retrospective cohort study including patients with nonvalvular AF attending an outpatient anticoagulation clinic of a tertiary hospital. Visits to the outpatient clinic and emergency, as well as hospital admissions to the institution, during 2014 were evaluated. The TTR was calculated through the Rosendaal´s method. Results: We analyzed 263 patients (median TTR, 62.5%). The low-risk group (score 0-1) had a better median TTR as compared with the high-risk group (score ≥ 2): 69.2% vs. 56.3%, p = 0.002. Similarly, the percentage of patients with TTR ≥ 60%, 65% or 70% was higher in the low-risk group (p < 0.001, p = 0.001 and p = 0.003, respectively). The high-risk group had a higher percentage of adverse events (11.2% vs. 7.2%), although not significant (p = 0.369). Conclusions: The SAMe-TT2R2 score proved to be effective to predict patients with a better TTR, but was not associated with adverse events.

Resumo Fundamento: O escore SAMe-TT2R2 foi desenvolvido visando predizer quais pacientes em anticoagulação oral com antagonistas da vitamina K (AVKs) atingirão um tempo na faixa terapêutica (TFT) adequado (> 65%-70%) no seguimento. Estudos também o relacionaram com a ocorrência de eventos adversos. Objetivos: Descrever o TFT de acordo com o escore, além de relacionar a pontuação obtida com a ocorrência de eventos adversos adversos em pacientes com fibrilação atrial (FA) não valvar em anticoagulação oral com AVKs. Métodos: Estudo de coorte retrospectivo incluindo pacientes com FA não valvar em acompanhamento em ambulatório de anticoagulação de um hospital terciário. Foi realizada uma avaliação retrospectiva de consultas ambulatoriais, visitas a emergência e internações hospitalares na instituição no período de janeiro-dezembro/2014. O TFT foi calculado aplicando-se o método de Rosendaal. Resultados: Foram analisados 263 pacientes com TFT mediano de 62,5%. O grupo de baixo risco (0-1 ponto) obteve um TFT mediano maior em comparação com o grupo de alto risco (≥ 2 pontos): 69,2% vs. 56,3%, p = 0,002. Da mesma forma, o percentual de pacientes com TFT ≥ 60%, 65% ou 70% foi superior nos pacientes de baixo risco (p < 0,001, p = 0,001 e p = 0,003, respectivamente). Os pacientes de alto risco tiveram um percentual maior de eventos adversos (11,2% vs. 7,2%), embora não significativo (p = 0,369). Conclusões: O escore SAMe-TT2R2 foi uma ferramenta eficaz na predição do TFT em pacientes com FA em uso de AVKs para anticoagulação, porém não se associou à ocorrência de eventos adversos.

Miocardite aguda sob a forma de síndrome coronariana aguda após infecção do trato urinário / Acute myocarditis presenting as acute coronary syndrome following urinary tract infection

A miocardite é cada vez mais diagnosticada, principalmente pela maior disponibilidade de métodos como a ressonância magnética cardíaca. A apresentação clínica é variável, geralmente posterior a uma infecção respiratória ou gastrointestinal, manifestando-se como síndrome coronariana aguda (SCA), insuficiência cardíaca aguda ou crônica, arritmias cardíacas ou mesmo choque cardiogênico inexplicável. Relatos de casos de miocardite após infecção do trato urinário (ITU) são escassos. Neste relato, descrevemos o caso de um paciente masculino de 24 anos com miocardite após ITU que se apresentou sob a forma de SCA(AU)

The diagnosis of myocarditis has increased mainly due to greater availability of methods such as cardiac magnetic resonance (CMR). Its clinical presentation varies, usually following respiratory or gastrointestinal tract infection, in patients presenting with acute coronary syndrome (ACS), acute or chronic heart failure, cardiac arrhythmias, or even unexplained cardiogenic shock. Case reports of patients with myocarditis following urinary tract infection (UTI) are scarce. This is a case report of a 24-year-old male patient with myocarditis with symptoms of ACS following UTI(AU)

Left ventricular noncompaction and pre-excitation: an unusual finding in adults

Left ventricular noncompaction (LVNC) is a rare form of cardiomyopathy characterized by prominent left ventricular (LV) trabeculae, deep intertrabecular recesses, and the thin compacted layer. The disease is potentially associated with sudden cardiac death due to LV dysfunction and ventricular arrhythmias. The presence of accessory pathway and Wolff-Parkinson-White syndrome is particularly rare in adults. Here we describe the rare association of LVNC and ventricular pre-excitation in an 18-year-old female with neonatal hypoxic brain injury (AU)

Desfechos cardiovasculares em pacientes tratados com intervenção percutânea coronária primária em hospital geral terciário / Cardiovascular outcomes in patients treated with primary percutaneous coronary intervention in a general tertiary hospital

Introdução: Existem poucos dados nacionais a respeito dos resultados da intervenção coronária percutânea (ICP) primária, e os registros são uma ótima ferramenta para a avaliação do perfil dos pacientes e dos desfechos pós-procedimento. O objetivo deste estudo foi descrever o perfil dos pacientes com ICP primária em um hospital geral terciário, bem como avaliar os desfechos cardiovasculares hospitalares e em 30 dias. Métodos: Foram incluídos todos os pacientes submetidos à ICP primária entre 2012 a 2015. Trata-se de um registro prospectivo, no qual os desfechos clínicos analisados foram a ocorrência de morte, infarto ou acidente vascular cerebral, e eventos cardiovasculares e cerebrovasculares maiores (ECCAM). Resultados: Foram incluídos 323 pacientes, com idade 60 ± 12 anos, sendo 66,7% do sexo masculino, 28,5% diabéticos. Na admissão, 13,5% dos pacientes apresentavam-se em Killip III/IV. O tempo dor-porta foi de 4,4 ± 2,5 horas e o tempo porta-balão foi 68,0 ± 34,0 minutos. A mortalidade hospitalar foi de 9,9%, e 18,3% dos pacientes apresentaram ECCAM em 30 dias. Conclusões: Os pacientes submetidos à ICP primária apresentaram taxas elevadas de ECCAM, que podem ser atribuídas à apresentação clínica mais grave e a um longo tempo de isquemia. Um atendimento mais rápido destes pacientes, variável modificável, demanda uma atenção imediata do sistema de saúde

Background: There are few national data on the results of primary percutaneous coronary intervention (PCI), and registries are a great tool for assessing patient profiles and post-procedure outcomes. The aim of this study was to describe the profile of patients with primary PCI in a general tertiary hospital, as well as to evaluate in-hospital and 30-day cardiovascular outcomes. Methods: The study included all patients submitted to primary PCI between 2012 and 2015. This was a prospective registry, in which the analyzed clinical outcomes were the occurrence of death, infarction, or stroke, and major cardiovascular and cerebrovascular events (MACCE). Results: The study included 323 patients, aged 60 ± 12 years, of whom 66.7% were males, 28.5% diabetics. At admission, 13.5% of the patients were classified as Killip class III/IV. The pain-to-door time was 4.4 ± 2.5 hours and the door-to-balloon time was 68.0 ± 34.0 minutes. Hospital mortality was 9.9%, and 18.3% of the patients presented MACCE in 30 days. Conclusions: Patients submitted to primary PCI had high rates of MACCE, which can be attributed to the more severe clinical presentation and to a long time of ischemia. The faster treatment of these patients, a modifiable variable, demands immediate attention from the health system

Large aortic aneurysm and dissection in a patient with Marfan’s syndrome

Marfan’s syndrome is an autosomal dominant disorder of connective tissue affecting approximately 1 in 5000 people. In individuals with this syndrome, more than 90% of deaths from known causes result from cardiovascular complications, such as aortic dissection, aortic regurgitation, and congestive cardiac failure. In this report, we present a patient with a large symptomatic aortic aneurysm and chronic dissection, severe aortic regurgitation and cardiomegaly, treated successfully with resection of the proximal aorta and placement of a mechanic aortic valved graft...

Major bleeding risk assessment in atrial fibrillation patients taking vitamin K antagonists

The use of risk scores for the assessment of major bleeding and stroke in patients with atrial fibrillation (AF) helps evaluate the risks and benefits of oral anticoagulation therapy. The aim of this study was to describe the percentage of patients receiving anticoagulants for non-valvular AF with a high risk of major bleeding based on the HAS-BLED score, as well as identify potential modifiable risk factors of bleeding and compare the risk of major bleeding with the risk of stroke. Methods: Retrospective cohort study involving patients of the anticoagulation outpatient clinic of the Division of Internal Medicine at Hospital de Clínicas de Porto Alegre. Major bleeding risk was estimated based on the HAS-BLED score and stroke risk was determined using the CHADS2 and CHA2 DS2 -VASc scores. Results: Sixty-three patients were investigated (mean age 74.3±10.9 years). The median HAS-BLED score was 2 points, 19 (30.2%) patients had a score ≥ 3 (high risk). The most prevalent modifiable risk factors were labile TP/INR (36.5%) and concomitant use of drugs (30.2%). The absolute risk of major bleeding based on the HAS-BLED score was higher than the risk of stroke in three (4.8%) and four (6.3%) patients in comparison with the CHADS2 and CHA2 DS2 -VASc score, respectively. Conclusions: We concluded that the percentage of patients with high risk of major bleeding is similar to the rate found in the national literature (30.2%). In addition, the most prevalent modifiable risk factors in our cohort were labile TP/INR and concomitant drug use...

Infarto com supradesnivelamento do segmento ST e trombo coronariano extenso em paciente com anemia falciforme / ST-segment elevation myocardial infarction with extensive coronary thrombus in a patient with sickle cell anemia

O infarto agudo do miocárdio em pacientes com anemia falciforme é, muitas vezes, subdiagnosticado em virtude de fatores de confusão (por exemplo, doença vaso-oclusiva, levando a crises dolorosas). Na maioria dos casos relatados na literatura, as artérias coronárias estavam pérvias e sem lesões. Neste relato de caso, descrevemos a presença de trombo coronariano extenso em paciente com anemia falciforme, apresentando-se sob a forma de infarto agudo do miocárdio com supradesnivelamento do segmento ST, manejado satisfatoriamente com a associação de anticoagulantes e antiplaquetários.

Myocardial infarction in patients with sickle cell anemia is often underdiagnosed due to confounding factors (e.g., vasoocclusive disease leading to painful crisis). In the majority of reported cases, the coronary arteries were pervious and without stenotic lesions. In this case report, we describe the presence of an extensive coronary thrombus in a patient with sickle cell anemia presenting with ST elevation myocardial infarction, managed satisfactorily with the association of anticoagulants and antiplatelet drugs.

Cardiomiopatia Hipertrófica Obstrutiva Médio-Ventricular / Mid-Ventricular Hypertrophic Obstructive Cardiomyopathy

Idade avançada e incidência de fibrilação atrial em pós-operatório de troca valvar aórtica / Advanced age and incidence of atrial fibrillation in the postoperative period of aortic valve replacement

Objetivo: Descrever, em idosos, a correlação entre faixa etária e ocorrência de fibrilação atrial após cirurgia por estenose aórtica, além de avaliar a influência da ocorrência de fibrilação atrial na incidência de acidente vascular cerebral, tempo de internação e mortalidade hospitalar. Métodos: Estudo transversal retrospectivo incluindo pacientes com idade > 70 anos submetidos à cirurgia de troca valvar aórtica isolada. Resultados: Foram estudados 348 pacientes com idade média de 76,8±4,6 anos. A incidência de fibrilação atrial no pós-operatório foi 32,8% (n=114), sendo superior nos pacientes > 80 anos (42,9 vs. 28,8% 70-79 anos, P=0,017) e havendo significância estatística limítrofe (P=0,055) para tendência linear na correlação idade e incidência de fibrilação atrial. Verificou-se significativo maior tempo de internação na Unidade de Terapia Intensiva e hospitalar total, porém, não se observou maior taxa de acidente vascular cerebral ou de mortalidade hospitalar decorrente da fibrilação atrial. Conclusão: A incidência de fibrilação atrial no pós-operatório de cirurgia para estenose valvar aórtica em pacientes idosos com > 70 anos foi elevada e linearmente correlacionada ao avanço da idade, especialmente após 80 anos, causando aumento dos tempos de internação total e em Unidade de Terapia Intensiva, sem aumento significativo da morbimortalidade. O conhecimento desses dados é importante para evidenciar a necessidade de medidas profiláticas e de tratamento precoce dessa arritmia nesse subgrupo. .

Objective: This study aims to describe the correlation between age and occurrence of atrial fibrillation after aortic stenosis surgery in the elderly as well as evaluate the influence of atrial fibrillation on the incidence of strokes, hospital length of stay, and hospital mortality. Methods: Cross-sectional retrospective study of > 70 year-old patients who underwent isolated aortic valve replacement. Results: 348 patients were included in the study (mean age 76.8±4.6 years). Overall, post-operative atrial fibrillation was 32.8% (n=114), but it was higher in patients aged 80 years and older (42.9% versus 28.8% in patients aged 70-79 years, P=0.017). There was borderline significance for linear correlation between age and atrial fibrillation (P=0.055). Intensive Care Unit and hospital lengths of stay were significantly increased in atrial fibrillation (P<0.001), but there was no increase in mortality or stroke associated with atrial fibrillation. Conclusion: Post-operative atrial fibrillation incidence in aortic valve replacement is high and correlates with age in patients aged 70 years and older and significantly more pronounced in patients aged 80 years. There was increased length of stay at Intensive Care Unit and hospital, but there was no increase in mortality or stroke. These data are important for planning prophylaxis and early treatment for this subgroup. .

Infective endocarditis with spondylodiscitis after prostate biopsy

Transrectal ultrasound-guided prostate needle biopsy is the ideal method of obtaining prostate specimens for histological analysis and is therefore often used in clinical practice. In most studies, prostate biopsy is considered a safe procedure with few major complications. In the present report, we describe a case of endocarditis with spondylodiscitis, two very rare complications associated with prostate biopsy. In the present report, we describe a case of infective endocarditis (IE) with spondylodiscitis (SD), two very rare complications of prostate biopsy. Only a few cases have been described in the literature reporting IE or SD as complications of prostate biopsy.
