Resumo Fundamento A angiotomografia coronária (ATC) tem sido usada para avaliação de dor torácica principalmente em pacientes de baixo risco, e poucos dados existem com pacientes em risco intermediário. Objetivo Avaliar o desempenho de medidas seriadas de troponinas sensíveis e de ATC em pacientes de risco intermediário. Métodos Um total de 100 pacientes com dor torácica, TIMI score 3 ou 4 e troponina negativa foram prospectivamente incluídos. Todos os pacientes foram submetidos à ATC, e aqueles com obstruções ≥ 50% foram encaminhados à cineangiocoronariografia. Pacientes com lesões < 50% recebiam alta hospitalar, receberam alta e foram contatados 30 dias depois por telefonema para avaliação dos desfechos clínicos. Os desfechos foram hospitalização, morte, e infarto agudo do miocárdio em 30 dias. A comparação entre os métodos foi realizada pelo teste de concordância kappa. O desempenho das medidas de troponina e da ATC na detecção de lesões coronárias significativas e desfechos clínicos foi calculado. Os resultados foram considerados estatisticamente significativos quando p <0,05. Resultados Estenose coronária ≥ 50% na ATC foi encontrada em 38% dos pacientes e lesões coronárias significativas na angiografia coronária foram encontradas em 31 pacientes. Dois eventos clínicos foram observados. A análise de concordância Kappa mostrou baixa concordância entre as medidas de troponina e ATC na detecção de lesões coronárias significativas (kappa = 0,022, p = 0,78). O desempenho da ATC para detectar lesões coronárias significativas na angiografia coronária ou para prever eventos clínicos em 30 dias foi melhor que as medidas de troponina sensível (acurácia de 91% versus 60%). Conclusão ATC teve melhor desempenho que as medidas seriadas de troponina na detecção de doença coronariana significativa em pacientes com dor torácica e risco intermediário para eventos cardiovasculares.

Abstract Background Coronary tomography angiography (CTA) has been mainly used for chest pain evaluation in low-risk patients, and few data exist regarding patients at intermediate risk. Objective To evaluate the performance of serial measures of sensitive troponin and CTA in intermediate-risk patients. Methods A total of 100 patients with chest pain, TIMI risk scores of 3 or 4, and negative troponin were prospectively included. All patients underwent CTA and those with coronary stenosis ≥ 50% were referred to invasive coronary angiography. Patients with coronary lesions <50% were discharged and contacted 30 days later by a telephone call to assess clinical outcomes. Outcomes were hospitalization, death, and myocardial infarction at 30 days. The comparison between methods was performed by Kappa agreement test. The performance of troponin measures and CTA for detecting significant coronary lesions and clinical outcomes was calculated. Results were considered statistically significant when p < 0.05. Results Coronary stenosis ≥ 50% on CTA was found in 38% of patients and significant coronary lesions on coronary angiography were found in 31 patients. Two clinical events were observed. Kappa agreement analysis showed low agreement between troponin measures and CTA in the detection of significant coronary lesions (kappa = 0.022, p = 0.78). The performance of CTA for detecting significant coronary lesions on coronary angiography or for predicting clinical events at 30 days was better than sensitive troponin measures (accuracy of 91% versus 60%). Conclusion CTA performed better than sensitive troponin measures in the detection of significant coronary disease in patients with chest pain and intermediate risk for cardiovascular events.

Abstract: En | Text: En | PDF: En

OBJECTIVES: Recent studies have revealed a relationship between beta-blocker use and worse prognosis in acute coronary syndrome, mainly due to a higher incidence of cardiogenic shock. However, the relevance of this relationship in the reperfusion era is unknown. The aim of this study was to analyze the outcomes of patients with acute coronary syndrome that started oral beta-blockers within the first 24 hours of hospital admission (group I) compared to patients who did not use oral beta-blockers in this timeframe (group II). METHODS: This was an observational, retrospective and multicentric study with 2,553 patients (2,212 in group I and 341 in group II). Data regarding demographic characteristics, coronary treatment and medication use in the hospital were obtained. The primary endpoint was in-hospital all-cause mortality. The groups were compared by ANOVA and the chi-square test. Multivariate analysis was conducted by logistic regression and results were considered significant when p<0.05. RESULTS: Significant differences were observed between the groups in the use of angiotensin-converting enzyme inhibitors, enoxaparin, and statins; creatinine levels; ejection fraction; tabagism; age; and previous coronary artery bypass graft. Significant differences were also observed between the groups in mortality (2.67% vs 9.09%, OR=0.35, p=0.02) and major adverse cardiovascular events (11% vs 29.5%, OR=4.55, p=0.02). CONCLUSIONS: Patients with acute coronary syndrome who underwent early intervention with oral beta-blockers during the first 24 hours of hospital admission had a lower in-hospital death rate and experienced fewer major adverse cardiovascular events with no increase in cardiogenic shock or sustained ventricular arrhythmias compared to patients who did not receive oral beta-blockers within this timeframe.

Objetivo No Brasil, há poucas descrições na literatura referentes ao padrão angiográfico e a características clínicas em pacientes jovens com síndrome coronariana aguda, apesar do número evidente de casos nessa população. O objetivo deste trabalho foi avaliar quais as características clínicas que mais se associam com a síndrome coronariana aguda em pacientes jovens e quais os desfechos a longo prazo nessa população.Métodos Trata-se de estudo prospectivo observacional com 268 pacientes com menos de 55 anos de idade com síndrome coronariana aguda, realizado entre maio de 2010 e maio de 2013. Foram obtidos dados demográficos, laboratoriais, angiográficos e do tratamento coronário adotado. Análise estatística foi apresentada sob a forma de porcentagens e valores absolutos.Resultados Aproximadamente 57% eram homens e a mediana de idade foi de 50 anos (30 a 55). Observou-se como principais fatores de risco hipertensão (68%), tabagismo (67%) e dislipidemia (43%). Dor típica esteve presente em 90% dos pacientes. Nos indivíduos jovens, observou-se supradesnivelamento de ST em 25,7% dos casos. Aproximadamente 56,5% dos pacientes apresentaram padrão angiográfico uniarterial. Cerca de 7,1% foram submetidos à cirurgia de revascularização miocárdica e 42,1% à angioplastia coronária. A mortalidade intra-hospitalar encontrada foi de 1,5%, e o índice de desfechos combinados (acidente vascular cerebral, choque cardiogênico, reinfarto e arritmias) foi de 13,8%. Após seguimento médio de 10 meses, a mortalidade foi de 9,8%, enquanto 25,4% dos pacientes apresentaram novos eventos isquêmicos e 37,3%, necessidade de reinternação.Conclusão A curto prazo, pacientes jovens apresentam índices de mortalidade abaixo do esperado, quando comparados os índices observados em outros estudos. No entanto, observou-se aumento importante no número de eventos no seguimento de 10 meses.

Objective In Brazil, there are few descriptions in the literature on the angiographic pattern and clinical characteristics of young patients with acute coronary syndrome, despite the evident number of cases in the population. The objective of this study was to evaluate which clinical characteristics are most closely related to the acute coronary syndrome in young patients, and what long-term outcomes are in this population.Methods This is a prospective observational study with 268 patients aged under 55 years with acute coronary syndrome, carried out between May 2010 and May 2013. Data were obtained on demographics, laboratory test and angiography results, and the coronary treatment adopted. Statistical analysis was presented as percentages and absolute values.Results Approximately 57% were men and the median age was 50 years (30 to 55). The main risk factors were arterial hypertension (68%), smoking (67%), and dyslipidemia (43%). Typical pain was present in 90% of patients. In young individuals, 25.7% showed ST segment elevation. Approximately 56.5% of patients presented with a single-vessel angiographic pattern. About 7.1% were submitted to coronary bypass surgery, and 42.1% to percutaneous coronary angioplasty. Intrahospital mortality was 1.5%, and the combined event rate (cerebrovascular accident/stroke, cardiogenic shock, reinfarction, and arrhythmias) was 13.8%. After a mean follow-up of 10 months, mortality was 9.8%, while 25.4% of the patients had new ischemic events, and 37.3% required readmission to hospital.Conclusion In the short-term, young patients presented with mortality rates below what was expected when compared to the rates noted in other studies. However, there was a significant increase in the number of events in the 10-month follow-up.

FUNDAMENTO: Os pacientes com insuficiência cardíaca (IC) que necessitam ser hospitalizados para compensação constituem grupo de maior gravidade, que evoluem com alta mortalidade e alta taxa de re-hospitalizações. OBJETIVO: Procuramos avaliar a atual história natural da IC por meio da taxa de mortalidade e de re-hospitalizações, nessa nova era do bloqueio neuro-hormonal. MÉTODOS: Acompanhamos a evolução de 263 pacientes com FE média de 27,1%, internados para compensação, entre janeiro de 2005 e outubro de 2006. Foram hospitalizados somente os pacientes que após avaliação e medicação no PS não estavam em condições de ter alta. Os pacientes encontravam-se em CF III/IV, a idade média foi de 59,9±15,2 anos, a maioria homens e 63,1% necessitaram de inotrópicos para compensação na fase aguda. RESULTADOS: O tempo médio de internação foi de 25,1±16,7 dias. Durante a internação 23 (8,8%) morreram. Após a alta, no período médio de seguimento de 370 dias, dos 240 que tiveram alta, 123 (51,2%) procuraram o PS de 1 a 12 vezes (total de passagens: 350), sendo 76 re-internados, sendo a média de dias da re-hospitalização de 23,5±18,0. No primeiro ano de seguimento 62 (25,8%) pacientes morreram. CONCLUSÃO: A IC continua evoluindo com alta mortalidade e alta taxa de re-hospitalização. Ao final do primeiro ano 44,5% desses pacientes não necessitaram passar no PS ou morreram, números que indicam que devemos continuar dando grande atenção aos portadores de IC, na tentativa de mudar a história natural dos portadores dessa síndrome, cada vez mais freqüente.

BACKGROUND: Patients who require hospitalization because of decompensated HF represent a group of the most seriously ill individuals who evolve with high mortality and hospital readmission rates. OBJECTIVES: We sought to evaluate the current natural course of HF by analyzing mortality and readmission rates in this new era of neurohormonal blockage. METHODS: We followed the progress of 263 patients with a mean EF of 27.1%, admitted for decompensated HF between January 2005 and October 2006. Patients readmitted were only those whose health status precluded discharge after assessment and drug treatment in the Emergency Department. Patients were classified as HF-FC III/IV, mean age was 59.9±15.2 years, most were men, and 63.1% required inotropic drugs for cardiac compensation in the acute phase. RESULTS: Average hospital stay was 25.1±16.7 days. During hospitalization, 23 (8.8%) patients died. After discharge, over an average follow-up period of 370 days, of the 240 patients who were discharged 123 (51.2%) returned to the Emergency Department 1 to 12 times (total number of visits: 350); 76 of them were readmitted, and the average length of readmission stay was 23.5±18.0 days. Over the first year of follow-up, 62 (25.8%) patients died. CONCLUSIONS: HF remains a condition associated with high mortality and high hospital readmission rates. At the end of the first year, 44.5% of these patients had not needed to visit the ER or had died, which indicates that we should provide HF patients with the best possible care in an attempt to change the natural course of this increasingly frequent syndrome.

Homem de 65 anos com insuficiência cardíaca causada por hipertensão e cardiopatia isquêmica foi internado com dispnéia, escarro sanguinolento e dor pleurítica após uma viagem de ônibus com duração de 52 horas. A avaliação clínica e laboratorial incluiu tomografia helicoidal do tórax, que demonstrou um defeito de enchimento do principal ramo da artéria pulmonar direita e uma opacidade periférica regular de formato triangular no lobo inferior da parte inferior do pulmão. Após o diagnóstico de tromboembolia pulmonar, foi instituída terapia com heparina, seguida por varfarina. O paciente recebeu alta hospitalar. O diagnóstico de embolia pulmonar deve ser levado em consideração em pacientes com sintomas semelhantes aos deste paciente após longa viagem de ônibus.

A 65 year-old man with heart failure due to hypertensive and ischemic heart disease was admitted to the hospital with dyspnea, bloody sputum and pleuritic chest pain after a 52-hour bus trip. Clinical and laboratory evaluation included chest helical tomography that demonstrated a filling defect of the right main branch of the pulmonary artery and a regular peripheral opacity of triangular shape in the inferior lobe of the lower lung. The diagnosis of pulmonary thromboembolism was made and therapy with heparin, followed by warfarin was introduced. The patient was discharged from the hospital. The diagnosis of pulmonary embolism should be considered in patients with complaints like this patient after long-distance bus travel.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

OBJETIVO: Verificar se o tratamento com levosimendan seria mais dispendioso que o usual com dobutamina, uma vez que o preço dos medicamentos não representa a maior despesa no tratamento da descompensação cardíaca. MÉTODOS: Comparou-se o custo do tratamento de 18 pacientes hospitalizados devido a descompensação cardíaca, 9 tratados com dobutamina (grupo dobuta) e 9 com levosimendan (grupo levo). Os grupos foram semelhantes quanto à idade, sexo, classe funcional e função cardíaca. RESULTADOS: O custo do tratamento foi semelhante para os dois grupos. No grupo levo as despesas com medicamentos foram maiores, mas as relativas ao período de terapia intensiva e do material empregado foram menores. Levo - medicamentos: R$ 5.414,00; materiais: R$ 399,90; diárias hospitalares: R$ 5.061,20; serviços profissionais: R$ 3.241,80; final: R$ 14.117,00. Dobuta - medicamentos: R$ 2.320,10; materiais: R$ 1.665,70; diárias hospitalares: R$ 6.261,90; serviços profissionais: R$ 3.894,30; final: R$ 14.142,00. CONCLUSÃO: Apesar do preço mais elevado da droga, o custo global do tratamento foi semelhante para os pacientes tratados com dobutamina ou levosimendan. O paciente tratado com levosimendan permaneceu menos tempo em terapia intensiva.

OBJECTIVE: To assess whether the treatment with levosimendan is more expensive than the usual one with dobutamine, since price of medications does not usually represent the greatest expense in the treatment of cardiac decompensation. METHODS: The cost of treatment of 18 inpatients with cardiac decompensation, 9 of which treated with dobutamine (dobuta group) and 9 with levosimendan (levo group), was compared. Groups were similar concerning age, sex, functional class and cardiac function. RESULTS: Treatment costs were similar for both groups. In the levo group, the costs with the drug were higher than in the dobuta group, but those related to the length of stay in intensive care unit and to the material used during admission were lower. Levo - drug: R$ 5,414.00; material: R$ 399.90; hospital daily rates: R$ 5,061.20; professional honorarium: R$ 3,241.80; total costs: R$ 14,117.00. Dobuta - drug: R$ 2,320.10; materials: R$ 1,665.70; hospital daily rates: R$ 6,261.90; professional honorarium: R$ 3,894.30; total costs: R$ 14,142.00. CONCLUSION: Despite the higher price of levosimendan, the global cost of the treatment was similar for patients who were treated either with dobutamine or levosimendan. Patients who were treated with levosimendan had a shorter length of stay in intensive care unit.

OBJETIVO: Estudar as principais características clínicas dos pacientes com insuficiência cardíaca sobreviventes há mais de 24 meses após hospitalização para compensação. MÉTODOS: Estudados 126 pacientes com insuficiência cardíaca, em classe funcional III ou IV, com idade média de 51,7 anos, a maioria homens (73%), com fração de ejeção (FE) média de 0,36 e diâmetro diastólico (DD) do VE de 7,13 cm. Avaliaram-se as principais características clínicas e laboratoriais e no seguimento identificaram-se 25 (19.8%) pacientes que sobreviveram mais de 24 meses após a alta hospitalar. Compararam-se os dados dos sobreviventes (G1) aos dos que faleceram (G2) antes de 24 meses. RESULTADOS: No G1 encontraram-se níveis mais elevados do sódio sérico (138,3±3,4 vs 134,5±5,8 mEq/l; p=0,001), da pressão arterial (120,0 vs 96,7 mmHg; p=0,003) e da FE do VE (0,40±0,08 vs 0,34±0,09; p=0,004) e valores menores da uréia (59,8 vs 76,3 mg/dl; p=0,007), do tempo de protrombina (12,9 vs 14,8s; p=0,001), do DDVE (6,78±0,55 vs 7,22±0,91; p=0,003) e do diâmetro do AE (4,77 vs 4,99cm; p=0,0003). Houve mais sobreviventes entre os portadores de cardiomiopatia idiopática e hipertensiva do que entre os chagásicos e doença coronariana. Na análise multivariada permaneceram como variáveis preditoras independentes da mortalidade o DDVE > 7,8 cm (HR 1,95), o Na < 132 mEq/l (HR 2,30) e o tempo de protrombina > 14 seg (HR 1,69). CONCLUSÃO: O estudo permite predizer quais os pacientes com insuficiência cardíaca que poderão apresentar uma boa sobrevida após a alta e os com maior possibilidade de longa sobrevivência após a alta.

OBJECTIVE: To study the major clinical characteristics of patients with heart failure who survived more than 24 months after hospitalization for compensation. METHODS: The study comprised 126 patients with heart failure in functional class III or IV, with a mean age of 51.7 years. Most patients were men (73%), had a mean ejection fraction (EF) of 0.36 and left ventricular diastolic diameter (DD) of 7.13 cm. The major clinical and laboratory characteristics were assessed, and, on follow-up, 25 (19.8%) patients, who survived more than 24 months after hospital discharge, were identified. Data of survivors (G1) were compared with those of patients who died (G2) before 24 months. RESULTS: In G1, the following levels were greater: serum sodium (138.3±3.4 vs 134.5±5.8 mEq/L; P=0.001); blood pressure levels (120.0 vs 96.7 mm Hg; P=0.003); and LVEF levels (0.40±0.08 vs 0.34±0.09; P=0.004); and the following levels were lower: urea (59.8 vs 76.3 mg/dL; P=0.007); prothrombin time (12.9 vs 14.8 seconds; P=0.001); LVDD (6.78±0.55 vs 7.22±0.91; P=0.003); and LA diameter (4.77 vs 4.99cm; P=0.0003). More survivors were found among patients with idiopathic cardiomyopathy and arterial hypertension than among patients with Chagas' disease and coronary artery disease. In multivariate analysis, the following variables remained as independent predictors of mortality: LVDD > 7.8 cm (HR 1.95); Na < 132 mEq/L (HR 2.30); and prothrombin time > 14 seconds (HR 1.69). CONCLUSION: The study allowed predicting which patients with heart failure will have a good survival after hospital discharge and those with a greater chance of a long survival after discharge.

OBJECTIVE: To verify whether the serum levels of N-Terminal ProBNP fraction (ProBNP) allow us to identify with accuracy the clinical functional status of patients with heart failure (HF), because the clinical diagnosis of this syndrome is based basically on clinical data when the complementary tests have lower specificity. METHODS: Sixty-nine patients with a history of HF were studied. Their mean age of was 53.5 years and 78.3% were males. All underwent clinical and echocardiographic evaluations and a test to determine the serum dosage of ProBNP. According to clinical manifestation, patients were in the following functional classes (FC), 14% FC I, 40.6% FC II, 28.1% FC III, and 23.4% FC IV. The mean ejection fraction (EF) was 0.28. RESULTS: ProBNP did not differ according to age, sex, and cause of cardiopathy. No correlation existed between EF and the ProBNP serum level. ProBNP levels were significantly lower in patients in FC I than those in FC II (42 vs 326.7 pmol/L; P=0.0001), and in FC II than those in FC III (P=0.01). ProBNP levels did not differ statically between FC III and IV patients (888.1 vs 1082.8 pmol/L; P=0.25). ProBNP values greater than 100 pmol/L identify patients with decompensated HF with a sensitivity of 98%. CONCLUSION: ProBNP values over 100 pmol/L were indicative of HF, and patients with advanced HF had values over 270 pmol/L. A ProBNP dosage test was an excellent auxiliary in the clinical characterization of patients with HF.

OBJETIVO: Quantificar a influência do diurético na capacidade funcional em portadores de insuficiência cardíaca congestiva (ICC) descompensada, através do teste de caminhada. MÉTODOS: Estudamos 10 pacientes internados, com idade média de 47 anos, sendo cinco do sexo masculino, com ICC descompensada, em classe funcional III e IV (NYHA), submetidos ao teste de caminhada de 6 e 9min na admissão e alta. Foram obtidos registros na admissão e alta, do peso, do ecocardiograma, sódio, potássio, uréia, creatinina séricos, hematócrito e hemoglobina. O tratamento instituído foi o aumento da dose prévia de furosemida EV e/ou VO, associado ou não a diurético tiazídico, tendo sido mantidas as doses prévias de digital, captopril ou da associação de nitrato e hidralazina. RESULTADOS: O período de compensação variou entre 4 a 30 dias (média 8,7±7,8 dias). Ao ecocardiograma bidimensional apresentaram diâmetro do ventrículo esquerdo que variou de 47 a 81mm e a fração de ejeção de 0,26 a 0,74. A distância caminhada em 6min passou de 193,4±71,5m para 341,8±67,7m (p<0,00002 ) e em 9min passou de 268,1±119,6m para 518,0±114,8m (p<0,00005 ). Não houve diferença estatística entre os valores, na admissão e alta, do hematócrito, hemoglobina, uréia, creatinina e sódio. O potássio sérico médio à admissão era de 4,0±0,91mEq/l e na alta 4,69±1,00mEq/l (p= 0,01) e o peso dos pacientes na admissão e na alta foi de 58,9±6,42kg para 52,9±5,31kg, respectivamente (p<0,0006 ). CONCLUSÃO: A compensação da ICC com o uso de diurético induziu a uma melhora importante, a curto prazo, da capacidade física dos pacientes, demonstrada pelo aumento da distância caminhada em 6 e 9min. O diurético melhorou significativamente o desempenho físico.

PURPOSE: The 6-9 minute walking test was used in this study to evaluate the impact of these drugs on functional capacity of patients admitted to the Hospital because of Heart Failure (CHF). METHODS: Ten patients (5 males and 5 females) with mean age of 47 years and NYHA CHF functional class III or IV underwent a 6-9 minute walking test at admission and on the day of discharge from the Hospital. The following parameters were evaluated both at admission and discharge: body weight, echocardiography-derived LV dimensions and function, plasmatic levels of sodium, potassium, BUN, creatinine, hemoglobin and hematocrit. Treatment consisted of increasing outpatient dose of furosemide (IV and/or PO) plus the association of thiazide if necessary. The previous dose regimen of digitalis, ACE inhibitors or the association nitrate and hydralazine was kept unchanged. RESULTS: Time to compensation of CHF varied from 4 to 30 days (mean 8.7±7.8 days). LV end diastolic dimension varied from 47 to 81mm. LV EF spanned from 0.26 to 0.74. The 6min walking distance improved from 193.4± 71.5m to 341.8±67.7m (p<0.00002) and the 9min walking distance from 268.1±119.6m to 518.0±114.8m (p<0.00005). Hemoglobin, hematocrit, BUN, creatinine and sodium levels were unchanged from admission to discharge, whereas plasma potassium level increased from 4.0±0.91mEq/l to 4.69±1.00mEq/l (p=0.01), and body weight was reduced from 58.9±6.42kg to 52.9±5.31kg (p<0.0006). CONCLUSION: Compensating CHF with diuretics leads to a significant improvement in physical capacity. This benefit is already evident in the in-hospital phase.
