RESUMO

Abstract Background There has been an increase in the number of cases of Takotsubo syndrome (TTS) and of scientific publications on the theme over the last years. However, little is known about the status of this disease in Brazilian hospitals. Objective To assess mortality and major adverse cardiovascular events (MACE) during hospitalization and follow-up of TTS patients seen in a tertiary hospital in Brazil. Methods This was a retrospective, observational study on 48 patients. Clinical data, signs and symptoms, complementary tests, MACE and all-cause mortality were assessed on admission and during follow-up. Kaplan-Meier curves were used for analysis of all-cause mortality and risk for MACE at median follow-up. The 95% confidence interval was also calculated for a significance level of 5%. Results Mean age of patients was 71 years (SD±13 years), and most patients were women (n=41; 85.4%). During hospitalization, four patients (8.3%) died and five (10.4%) developed MACE. At median follow-up of 354.5 days (IQR of 81.5-896.5 days), the risk of all-cause mortality and MACE was 11.1% (95% CI= 1.8-20.3%) and 12.7% (95% CI= 3.3-22.3%), respectively. Conclusion TTS was associated with high morbidity and mortality rates in a tertiary hospital in Brazil, which were comparable to those observed in acute coronary syndrome. Therefore, the severity of TTS should not be underestimated, and new therapeutic strategies are required. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

RESUMO

BACKGROUND: Evidence regarding biomarkers for risk prediction in patients with infective endocarditis (IE) is limited. We aimed to investigate the value of a panel of biomarkers for the prediction of in-hospital mortality in patients with IE. METHODS: Between 2016 and 2018, consecutive IE patients admitted to the emergency department were prospectively included. Blood concentrations of nine biomarkers were measured at admission (D0) and on the seventh day (D7) of antibiotic therapy: C-reactive protein (CRP), sensitive troponin I (s-cTnI), procalcitonin, B-type natriuretic peptide (BNP), neutrophil gelatinase-associated lipocalin (NGAL), interleukin 6 (IL6), tumor necrosis factor α (TNF-α), proadrenomedullin, alpha-1-acid glycoprotein, and galectin 3. The primary endpoint was in-hospital mortality. RESULTS: Among 97 patients, 56% underwent cardiac surgery, and in-hospital mortality was 27%. At admission, six biomarkers were independent predictors of in-hospital mortality: s-cTnI (OR 3.4; 95%CI 1.8-6.4; P<0.001), BNP (OR 2.7; 95%CI 1.4-5.1; P=0.002), IL-6 (OR 2.06; 95%CI 1.3-3.7; P=0.019), procalcitonin (OR 1.9; 95%CI 1.1-3.2; P=0.018), TNF-α (OR 1.8; 95%CI 1.1-2.9; P=0.019), and CRP (OR 1.8; 95%CI 1.0-3.3; P=0.037). At admission, S-cTnI provided the highest accuracy for predicting mortality (area under the ROC curve: s-cTnI 0.812, BNP 0.727, IL-6 0.734, procalcitonin 0.684, TNF-α 0.675, CRP 0.670). After 7 days of antibiotic therapy, BNP and inflammatory biomarkers improved their performance (s-cTnI 0.814, BNP 0.823, IL-6 0.695, procalcitonin 0.802, TNF-α 0.554, CRP 0.759). CONCLUSION: S-cTnI concentration measured at admission had the highest accuracy for mortality prediction in patients with IE.

RESUMO

There is limited evidence in the literature regarding the administration of clopidogrel to acute coronary syndrome (ACS) in patients over 75 years of age. Most studies excluded this age group, making the subject controversial due to the increased risk of bleeding in this population. Objective: This is a retrospective, unicentric, and observational study aimed at assessing whether the administration of clopidogrel loading dose increases bleeding rates in patients over 75 years of age. Methods: Patients were divided into two groups: group I: 75 mg of clopidogrel; group II: 300-to 600-mg loading dose of clopidogrel. A total of 174 patients (129 in group I and 45 in group II) were included between May 2010 and May 2015. Statistical analysis: The primary outcome was bleeding (major and/or minor). The secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). The comparison between groups was performed through Q-square and T-test. The multivariate analysis was performed by logistic regression, being considered significant p < 0.05. Results: Comparisons between groups I and II showed differences in the prevalence of diabetes (46.5% vs. 24.4%, p = 0.01), arterial hypertension (90.7% vs. 75, p = 0.01), dyslipidemia (62% vs. 42.2%, p = 0.021), ST segment elevation (11.6% vs. 26.6%, p = 0.016) and coronary intervention percutaneous (16.5% vs. 62.2%, p < 0.0001), respectively. In the multivariate analysis, significant differences were observed between groups I and II in relation to the occurrence of bleeding (8.5% vs. 20%, OR = 0.173, 95% CI: 0.049 - 0.614, p = 0.007). Conclusion: A loading dose of 300 mg or more of clopidogrel

RESUMO

AIMS: The diagnosis of acute aortic syndromes (AASs) is challenging and requires integrated strategies. Transthoracic focused cardiac ultrasound (FoCUS) is endorsed by guidelines as a first-line/triage tool allowing rapid bedside assessment of the aorta. However, the performance of FoCUS in the European Society of Cardiology-recommended workup of AASs awaits validation. METHODS AND RESULTS: This was a prespecified subanalysis of the ADvISED multicentre prospective study. Patients with suspected AAS underwent FoCUS for detection of direct/indirect signs of AAS. Clinical probability assessment was performed with the aortic dissection detection risk score (ADD-RS). Case adjudication was based on advanced imaging, surgery, autopsy, or 14-day follow-up. An AAS was diagnosed in 146 (17.4%) of 839 patients. Presence of direct FoCUS signs had a sensitivity and specificity of 45.2% [95% confidence interval (CI) 37-53.6%] and 97.4% (95% CI 95.9-98.4%), while presence of any FoCUS sign had a sensitivity and specificity of 89% (95% CI 82.8-93.6%) and 74.5% (95% CI 71-77.7%) for AAS. The additive value of FoCUS was most evident within low clinical probability (ADD-RS ≤1). Herein, direct FoCUS signs were identified in 40 (4.8%) patients (P < 0.001), including 29 with AAS. ADD-RS ≤1 plus negative FoCUS for AAS rule-out had a sensitivity of 93.8% (95% CI 88.6-97.1%) and a failure rate of 1.9% (95% CI 0.9-3.6%). Addition of negative D-dimer led to a failure rate of 0% (95% CI 0-1.2%). CONCLUSION: FoCUS has additive value in the workup of AASs. Direct FoCUS signs can rapidly identify patients requiring advanced imaging despite low clinical probability. In integrated bundles, negative FoCUS is useful for rule-out of AASs.

RESUMO

OBJECTIVE: Cardiac myxoma is a benign neoplasm, which corresponds to the most common primary heart tumour, responsible for about 50% of the cases. In general, 75-80% of myxomas are located in the left atrium, 18% in the right atrium, and more rarely in the ventricles or multicentric. Right atrial myxoma, in particular, can obstruct the tricuspid valve, causing symptoms of right heart failure, peripheral oedema, hepatic congestion, and syncope. Systemic embolization occurs in 30% of cases, by either tumour fragmentation or total tumour detachment. CONCLUSIONS: In the present report, we present a case of a symptomatic patient, who showed a large right intra-atrial lesion, with consequent superior vena cava syndrome, and then underwent surgical resection at admission.

RESUMO O mixoma cardíaco é uma neoplasia benigna, que corresponde ao tumor primário mais comum do coração, responsável por cerca de 50% dos casos. De modo geral, 75 a 80% dos mixomas estão localizados no átrio esquerdo, 18% no átrio direito, e mais raramente, nos ventrículos ou multicêntricos. O mixoma atrial direito, em particular, pode obstruir a válvula tricúspide, causando sintomas de insuficiência cardíaca direita, edema periférico, congestão hepática e síncope. A embolização sistêmica ocorre em 30% dos casos, quer pela fragmentação do tumor ou pelo desprendimento total do mesmo. No presente relato, apresentamos um caso de uma paciente sintomática, que evidenciou grande lesão intra-atrial direita, com consequente síndrome da veia cava superior, sendo, então, submetida a ressecção cirúrgica na internação.

RESUMO

Abstract Background: Gender-related differences have been reported in patients with acute coronary syndrome. The description of this comparative finding in a Brazilian registry has not yet been documented. Objective: To compare male vs. female patients regarding the baseline characteristics, coronary findings, treatment and in-hospital and long-term prognosis. Methods: This is a retrospective, multicenter and observational study that included 3,745 patients (2,437 males and 1,308 females) between May 2010 and May 2015. The primary in-hospital outcome was all-cause mortality. The secondary outcome consisted of combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). The comparison between groups was performed using the chi-square and the t test, considering p < 0.05 as significant. In the long term, mortality and combined events were assessed using the Kaplan-Meier method, with a mean follow-up of 8.79 months. Results: The mean age was 60.3 years for males and 64.6 for females (p < 0.0001). The most prevalent risk factor was systemic arterial hypertension in 72.9% of the women and 67.8% of the men (p = 0.001). Percutaneous coronary intervention was carried out in 44.9% of the males and 35.4% of the females (p < 0.0001), and coronary artery bypass grafting (CABG) was performed in 17% of the males and 11.8% of females (p < 0.0001), with a higher prevalence of three-vessel coronary artery disease in males (27.3% vs. 16.2%, p < 0.0001). Approximately 79.9% of the female patients received a diagnosis of acute coronary syndrome without ST-segment elevation, while in the male patients, this diagnosis was attained in 71.5% (p < 0.0001). No significant differences were observed between the groups in the short and long term, regarding both mortality and the combined events. Conclusion: Several gender-related differences were observed in patients with acute coronary syndrome regarding the demographic characteristics, coronary artery disease pattern and implemented treatment. However, the prognostic evolution was similar between the groups.


Resumo Fundamento: Existem diferenças relatadas entre pacientes com síndrome coronariana aguda, de acordo com o sexo. A descrição deste achado comparativo em registro brasileiro ainda não foi documentada. Objetivo: Comparar pacientes do sexo masculino vs. feminino quanto a características basais, achados coronarianos, tratamento e prognóstico intra-hospitalar e em longo prazo. Métodos: Trata-se de estudo retrospectivo, multicêntrico e observacional, no qual foram incluídos 3.745 pacientes (2.437 do sexo masculino e 1.308 do sexo feminino) entre maio de 2010 e maio de 2015. O desfecho primário intra-hospitalar foi mortalidade por todas as causas. O desfecho secundário foi eventos combinados (choque cardiogênico, reinfarto, morte, acidente vascular cerebral e sangramento). A comparação entre grupos foi realizada por meio de qui-quadrado e teste t, sendo considerado significativo p < 0,05. Em longo prazo, foram avaliados a mortalidade e os eventos combinados pelo método Kaplan-Meier, com seguimento médio de 8,79 meses. Resultados: A média de idade foi de 60,3 anos no sexo masculino e 64,6 no feminino (p < 0,0001). O fator de risco mais prevalente foi hipertensão arterial sistêmica em 72,9% das mulheres e 67,8% nos homens (p = 0,001). Intervenção coronária percutânea foi realizada em 44,9% no sexo masculino e 35,4% no feminino (p < 0,0001), e revascularização miocárdica cirúrgica em 17% no sexo masculino e 11,8% no feminino (p < 0,0001), com maior prevalência de padrão coronariano triarterial no sexo masculino (27,3% vs. 16,2%; p < 0,0001). Cerca de 79,9% dos pacientes do sexo feminino enquadraram-se no diagnóstico de síndrome coronariana aguda sem supradesnivelamento do segmento ST, enquanto no sexo masculino este número foi de 71,5% (p < 0,0001). Em curto e longo prazos não se observaram diferenças significativas entre os grupos, tanto em mortalidade quanto em eventos combinados. Conclusão: Observaram-se múltiplas diferenças relacionadas ao sexo em pacientes com síndrome coronariana aguda no que se refere a características demográficas, padrão coronariano e tratamento adotado. No entanto, a evolução prognóstica foi semelhante entre os grupos.

RESUMO

Objetivo: As doenças cardiovasculares são responsáveis pela principal causa de óbitos na população adulta mundial, sendo a síndrome coronariana aguda (SCA) a mais prevalente entre elas. Resultados: Sabemos que hoje, do ponto de vista epidemiológico, a coronariopatia aguda sem supradesnivelamento de ST tornou-se a forma mais frequente de apresentação clínica da SCA, aproximadamente, em 62% dos casos. Nos últimos anos, houve importantes avanços em relação à terapêutica antiplaquetária e anticoagu-lante capazes de reduzir a mortalidade associada à doença coronariana. Além disso, a estratificação invasiva precoce teve papel fundamental nesse incremento de prognóstico. Conclusão:Dessa forma, atualmente, a escolha terapêutica e de estratificação devem ser avaliadas individual


Cardiovascular diseases are the main cause of death in the adult population worldwide, with acute coronary syndrome (ACS) being the most prevalent. We know that, presently, from an epidemiological point of view, non-ST elevation ACS is the most frequent form of clinical presentation of ACS, in about 62% of cases. Recently, important advances regarding antiplatelet and anticoagulant therapy exist, capable of reducing mortality associated with coronary heart disease. Moreover, early invasive stratification has played a key role in the improvement in prognosis. Thus, the choice of therapy and stratification should be evaluated individually and can modify short- and long-term outcome
