RESUMEN
SUMMARY OBJECTIVE: Hydroxychloroquine and Ivermectin are advocated as potential treatments for coronavirus disease 2019 (COVID-19) despite the lack of supportive clinical evidence. In this study, outcomes associated with Hydroxychloroquine and/or Ivermectin were determined in a series of patients with confirmed COVID-19 from a single institution in Brazil. METHODS: Consecutive patients admitted between March and July 2020 were retrospectively analyzed and divided into four treatment categories: no treatment (Group 0), Ivermectin only (Group I), Hydroxychloroquine only (Group II), and Hydroxychloroquine and Ivermectin (Group III). Intensive care unit admission, mechanical ventilation, and death were compared between the Groups. RESULTS: A total of 230 patients were included, with the following treatment distribution: 35.2% (0), 9.1% (I), 48.3% (II), and 7.4% (III). Groups I, II, and III had the higher rates of Intensive care unit admission, mechanical ventilation, or death (0: 23.5% versus I: 38.1% versus II: 37.8% versus III: 70.6%, p=0.002), and the greatest mortality was found in Group III (0 versus III: 13.6% versus 35.3%, p=0.03). In the multivariate analysis, Hydroxychloroquine remained significantly associated with death (OR 3.3, 95%CI 1.1-9.6, p=0.03). CONCLUSION: In a series of consecutive hospitalized patients with COVID-19, Ivermectin was not associated with improved outcomes and Hydroxychloroquine may have resulted in a harmful effect.

The prognostic value of atrial thrombi (AT) among elective patients with atrial fibrillation (AF) referred for a rhythm control strategy is unclear. In this study, clinical variables were correlated with the presence of AT and long term survival among 205 patients submitted to transesophageal echocardiography before elective AF cardioversion or ablation. Atrial thrombi were present in 7.8% of cases and were significantly associated with reduced survival. Obesity was the only independent clinical predictor of AT [OR 4.27 (1.15-15.79), p = 0.03]. In patients with AF, AT appear to be associated with adverse outcomes, possibly indicating more advanced atrial cardiomyopathy.

BACKGROUND: Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. OBJECTIVE: To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. METHODS: This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed this condition. Evaluated outcomes included triggering factor, analysis of exams, use of medications, complications, in-hospital mortality, and mortality during 1 year of follow-up. A significance level of 5% was adopted. RESULTS: The registry included 169 patients from 12 centers in the state of Rio de Janeiro, Brazil. Mean age was 70.9 ± 14.1 years, and 90.5% of patients were female; 63% of cases were primary TTS, and 37% were secondary. Troponin I was positive in 92.5% of patients, and median BNP was 395 (176.5; 1725). ST-segment elevation was present in 28% of patients. Median left ventricular ejection fraction was 40 (35; 48)%. We observed invasive mechanical ventilation in 25.7% of cases and shock in 17.4%. Mechanical circulatory support was used in 7.7%. In-hospital mortality was 10.6%, and mortality at 1 year of follow-up was 16.5%. Secondary TTS and cardiogenic shock were independent predictors of mortality. CONCLUSION: The results of the REMUTA show that TTS is not a benign pathology, as was once thought, especially regarding the secondary TTS group, which has a high rate of complications and mortality.

FUNDAMENTO: A síndrome de takotsubo (takotsubo) é uma forma de cardiomiopatia adquirida. Dados nacionais sobre essa condição são escassos. O Registro REMUTA é o primeiro a incluir dados multicêntricos dessa condição no nosso país. OBJETIVO: Descrever as características clínicas, prognóstico, tratamento intra-hospitalar e mortalidade hospitalar e em 1 ano de seguimento. MÉTODOS: Estudo observacional, retrospectivo, tipo registro. Incluídos pacientes internados com diagnóstico de takotsubo ou que desenvolveram esta condição durante internação por outra causa. Os desfechos avaliados incluíram fator desencadeador, análise dos exames, uso de medicações, complicações e óbito intra-hospitalar e em 1 ano de seguimento. O nível de significância adotado foi de 5%. RESULTADOS: Foram incluídos 169 pacientes, em 12 centros no Estado do Rio de Janeiro. A idade média foi de 70,9 ± 14,1 anos e 90,5% eram do sexo feminino; 63% dos casos foram de takotsubo primário e 37% secundário. Troponina I foi positiva em 92,5% dos pacientes e a mediana de BNP foi de 395 (176,5; 1725). Supradesnivelamento do segmento ST esteve presente em 28% dos pacientes. A fração de ejeção do ventrículo esquerdo teve mediana de 40 (35; 48)%. Observamos taxa de 25,7% de ventilação mecânica invasiva e 17,4% de choque. Suporte circulatório mecânico foi utilizado em 7,7%. A mortalidade intra-hospitalar foi de 10,6% e a mortalidade ao final de 1 ano foi de 16,5%. Takotsubo secundário e choque cardiogênico foram preditores independentes de mortalidade. CONCLUSÃO: Os resultados do REMUTA mostram que takotsubo não se trata de patologia benigna como se pensava, especialmente no grupo de takotsubo secundário que acarreta elevada taxa de complicações e de mortalidade.

The prevalence of coronary artery disease in young adults (<45 years of age) has been increasing steadily in recent decades. Although traditional cardiovascular risk factors can be identified in most cases, newly recognized associations are becoming progressively more relevant. The relationship between the factor V Leiden mutation and atherosclerosis has been a matter of debate due to conflicting data presented in previous studies. Presently described is the case of a previously asymptomatic 37-year-old woman with a significant family history of coronary artery disease who developed rapidly progressive angina within 1 month. After a positive non-invasive evaluation, coronary angiography demonstrated a significant obstruction in the proximal left anterior descending artery. Optical coherence tomography revealed a highly vulnerable lipid-rich atherosclerotic plaque. Coronary angioplasty followed by the implantation of 1 drug-eluting stent was successfully performed. A subsequent thrombophilia screening identified a heterozygous factor V R506Q mutation (factor V Leiden). Since there was no history of thromboembolic events, the patient was discharged using only aspirin, clopidogrel, atorvastatin, and atenolol. Further studies are needed to define the most appropriate management of young patients who manifest clinically significant atherosclerotic disease in association with hereditary thrombophilia.

OBJECTIVE: Complications after percutaneous coronary interventions (PCI) are associated with significant morbidity and mortality, although institutional discrepancies can occur when public and private hospitals coexist within the healthcare system. The aim of this study was to compare the in-hospital complication rates and mortality in addition to long-term survival following elective PCI in two reference public and private cardiology hospitals in Rio de Janeiro, Brazil. METHODS: From January 1st 2013 to December 31st 2014, a total of 440 procedures were identified in both hospitals (public: 328 vs. private: 112) and retrospectively analyzed by chart review. RESULTS: There were no significant differences between the two hospitals regarding the total number of procedures with at least one complication (public: 23.8 vs. private: 17.9%, p=0.2) or in-hospital mortality rates (public: 0.6% vs. private: 0%, p=0.5). Post-procedural renal insufficiency was more frequent in the private hospital, whereas coronary-related complications were more prevalent in the public hospital. After a mean follow up of 30.3 months (SD±9.2), the survival rate was also similar. CONCLUSIONS: Clinical complications after elective PCI are common both in public and private hospitals. Meticulous pre-procedural clinical assessment and patient selection as well as adherence to guideline-based practices could minimize the risk of PCI-related adverse events.

Contrast-induced thrombocytopenia is a rare complication distinguished by acute and severe platelet consumption, with spontaneous recovery within days. We describe a case of acute thrombocytopenia 6 hours after coronary angioplasty in a patient with a negative antiplatelet factor 4 test. The count reached 1 × 103/µL, but improved spontaneously to 210 × 103/µL after 8 days. In conclusion, physicians should be aware of this complication, particularly when dual antiplatelet therapy is being considered.
