ABSTRACT

BACKGROUND: C-reactive protein (CRP) is an inflammation biomarker that can be a predictor of adverse events in cardiovascular procedures. Its use in the assessment of long-term prognosis of transcatheter aortic valve implantation (TAVI) is still incipient. OBJECTIVE: To evaluate CRP as a prognostic marker in the first year after TAVI in aortic stenosis (AoS). METHODS: CRP was assessed on the first postoperative week in a retrospective cohort of patients with AoS. Pre- and post- CRP levels were correlated with mortality, and predictors of 1-year mortality were investigated. Multivariate Cox regression was performed to identify independent factors of 1-year mortality. RESULTS: This study evaluated 130 patients who underwent TAVI, with median age of 83 years, and 49% of women. High pre-TAVI CRP (> 0.5 mg/dL) was observed in 34.5% of the cases. Peak CRP was 7.0 (5.3-12.1) mg/dL no quarto dia. The rate of 1-year mortality was 14.5% (n = 19), being greater in the groups with high pre-TAVI CRP (68.8% vs 29.1%; p = 0,004) and with peak CRP ≥ 10.0 mg/dL (64.7% vs 30.8%; p = 0,009). Independent predictors of mortality were acute renal failure (ARF) (hazard ratio [HR] = 7.43; 95% confidence interval [95%CI], 2.1-24.7; p = 0,001), high pre-TAVI CRP (HR 4.15; 95%CI, 1.3-12.9; p = 0.01), and large blood transfusion [HR 4,68; 1,3-16,7; p = 0.02]. CONCLUSIONS: High pre-TAVI CRP showed to be an independent predictor of 1-year mortality, as well as the presence of ARF and large blood transfusions.


FUNDAMENTO: A proteína C-reativa (PCR) é um biomarcador de inflamação preditor de eventos adversos em procedimentos cardiovasculares. Na avaliação do implante da válvula aórtica transcateter (transcatheter aortic valve implantation, TAVI) em relação ao prognóstico de longo prazo ainda é incipiente. OBJETIVO: Avaliar a PCR como marcador prognóstico no primeiro ano pós-TAVI na estenose aórtica (EAo). MÉTODOS: A PCR foi avaliada na primeira semana do peroperatório numa coorte de casos retrospectiva com EAo. Correlacionou-se a PCR pré- e pós-TAVI com a mortalidade e foram pesquisados fatores preditores de mortalidade em 1 ano. Realizada regressão de Cox multivariada para identificar os preditores independentes de óbito em 1 ano. RESULTADOS: Estudados 130 pacientes submetidos a TAVI, com mediana de idade de 83 anos, sendo 49% deles do sexo feminino. A PCR pré-TAVI elevada (> 0,5 mg/dL) ocorreu em 34,5% dos casos. O pico de PCR foi 7,0 (5,3-12,1) mg/dL no quarto dia. A mortalidade em 1 ano foi 14,5% (n = 19), sendo maior nos grupos com PCR pré-TAVI elevada (68,8% vs 29,1%; p = 0,004) e pico de PCR ≥ 10,0 mg/dL (64,7% vs 30,8%; p = 0,009). Os fatores preditores independentes de mortalidade foram insuficiência renal aguda (IRA) [razão de risco (RR) = 7,43; intervalo de confiança de 95% (IC95%), 2,1-24,7; p = 0,001], PCR pré-TAVI elevada [RR = 4,15; IC95%, 1,3-12,9; p=0,01] e hemotransfusão volumosa [HR = 4,68; 1,3-16,7; p = 0,02]. CONCLUSÕES: A PCR pré-TAVI elevada mostrou-se fator preditor independente de mortalidade no primeiro ano, assim como a ocorrência de IRA e hemotransfusões volumosas.

ABSTRACT

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established procedure; however, atrioventricular block requiring permanent pacemaker implantation (PPI) is a common complication. OBJECTIVES: To determine the incidence, predictors and clinical outcomes of PPI after TAVI, focusing on how PPI affects left ventricular ejection fraction (LVEF) after TAVI. METHODS: The Brazilian Multicenter TAVI Registry included 819 patients submitted to TAVI due to severe aortic stenosis from 22 centers from January/2008 to January/2015. After exclusions, the predictors of PPI were assessed in 670 patients by use of multivariate regression. Analysis of the ROC curve was used to measure the ability of the predictors; p < 0.05 was the significance level adopted. RESULTS: Within 30 days from TAVI, 135 patients (20.1%) required PPI. Those patients were older (82.5 vs. 81.1 years; p = 0.047) and mainly of the male sex (59.3% vs 45%; p = 0.003). Hospital length of stay was longer in patients submitted to PPI (mean = 15.7 ± 25.7 vs. 11.8 ± 22.9 days; p < 0.001), but PPI affected neither all-cause death (26.7% vs. 25.6%; p = 0.80) nor cardiovascular death (14.1% vs. 14.8%; p = 0.84). By use of multivariate analysis, the previous presence of right bundle-branch block (RBBB) (OR, 6.19; 3.56-10.75; p ≤ 0.001), the use of CoreValve® prosthesis (OR, 3.16; 1.74-5.72; p ≤ 0.001) and baseline transaortic gradient > 50 mm Hg (OR, 1.86; 1.08-3.2; p = 0.025) were predictors of PPI. The estimated risk of PPI ranged from 4%, when none of those predictors was present, to 63%, in the presence of all of them. The model showed good ability to predict the need for PPI: 0.69 (95%CI: 0.64 - 0.74) in the ROC curve. The substudy of 287 echocardiograms during the 1-year follow-up showed worse LVEF course in patients submitted to PPI (p = 0.01). CONCLUSION: BRD prévio, gradiente aórtico médio > 50 mmHg e CoreValve® são preditores independentes de implante de MPD pós-TAVI. Ocorreu implante de MPD em aproximadamente 20% dos casos de TAVI, o que prolongou a internação hospitalar, mas não afetou a mortalidade. O implante de MPD afetou negativamente a FEVE pós-TAVI.

ABSTRACT

BACKGROUND: Transcatheter aortic valve implantation has become an option for high-surgical-risk patients with aortic valve disease. OBJECTIVE: To evaluate the in-hospital and one-year follow-up outcomes of transcatheter aortic valve implantation. METHODS: Prospective cohort study of transcatheter aortic valve implantation cases from July 2009 to February 2015. Analysis of clinical and procedural variables, correlating them with in-hospital and one-year mortality. RESULTS: A total of 136 patients with a mean age of 83 years (80-87) underwent heart valve implantation; of these, 49% were women, 131 (96.3%) had aortic stenosis, one (0.7%) had aortic regurgitation and four (2.9%) had prosthetic valve dysfunction. NYHA functional class was III or IV in 129 cases (94.8%). The baseline orifice area was 0.67 ± 0.17 cm2 and the mean left ventricular-aortic pressure gradient was 47.3±18.2 mmHg, with an STS score of 9.3% (4.8%-22.3%). The prostheses implanted were self-expanding in 97% of cases. Perioperative mortality was 1.5%; 30-day mortality, 5.9%; in-hospital mortality, 8.1%; and one-year mortality, 15.5%. Blood transfusion (relative risk of 54; p = 0.0003) and pulmonary arterial hypertension (relative risk of 5.3; p = 0.036) were predictive of in-hospital mortality. Peak C-reactive protein (relative risk of 1.8; p = 0.013) and blood transfusion (relative risk of 8.3; p = 0.0009) were predictive of 1-year mortality. At 30 days, 97% of patients were in NYHA functional class I/II; at one year, this figure reached 96%. CONCLUSION: Transcatheter aortic valve implantation was performed with a high success rate and low mortality. Blood transfusion was associated with higher in-hospital and one-year mortality. Peak C-reactive protein was associated with one-year mortality.

ABSTRACT

BACKGROUND: Transcatheter aortic valve implantation (TAVI) was established as an important alternative for high-risk patients with severe aortic stenosis. However, there are few data in the literature regarding coronary obstruction, that although rare, is a potentially fatal complication. OBJECTIVE: Evaluate this complication in Brazil. METHODS: We evaluated all patients presenting coronary obstruction from the Brazilian Registry of TAVI. Main baseline and procedural characteristics, management of the complication, and clinical outcomes were collected from all patients. RESULTS: From 418 consecutive TAVI procedures, coronary obstruction occurred in 3 cases (incidence of 0.72%). All patients were women, without prior coronary artery bypass grafting (CABG), and with mean age of 85 ± 3 years, logistic EuroSCORE of 15 ± 6% and STS-PROM score of 9 ± 4%. All of the cases were performed with balloon-expandable Sapien XT prosthesis. In one patient, with pre-procedural computed tomography data, coronary arteries presented a low height and a narrow sinus of Valsalva. All patients presented with clinically significant severe maintained hypotension, immediately after valve implantation, and even though coronary angioplasty with stent implantation was successfully performed in all cases, patients died during hospitalization, being two periprocedurally. CONCLUSION: Coronary obstruction following TAVI is a rare but potentially fatal complication, being more frequent in women and with the balloon-expandable prosthesis. Anatomical factors might be related with its increased occurrence, highlighting the importance of a good pre-procedural evaluation of the patients in order to avoid this severe complication.

Conclusion: BRD prévio, gradiente aórtico médio > 50 mmHg e CoreValve® são preditores independentes de implante de MPD pós-TAVI.

Resumo Fundamento: O implante valvar aórtico transcateter (TAVI) está bem estabelecido, porém, o bloqueio atrioventricular, com necessidade de marca-passo definitivo (MPD), é complicação frequente. Objetivo: Determinar a incidência, preditores e desfechos clínicos de implante de MPD após TAVI, focando em como a evolução da fração de ejeção do ventrículo esquerdo (FEVE), após o TAVI, é afetada pelo MPD. Métodos: No registro brasileiro foram incluídos 819 pacientes submetidos a TAVI por estenose aórtica severa em 22 centros entre janeiro/2008 e janeiro/2015. Após exclusões, os preditores de implante de MPD foram avaliados em 670 pacientes por regressão multivariada. Análise da curva ROC foi utilizada para medir a habilidade dos preditores; p < 0,05 foi considerado significativo. Resultados: Aos 30 dias, 135 pacientes (20,1%) necessitaram de MPD. Tais pacientes eram mais velhos (82,5 vs. 81,1 anos; p = 0,047) e predominantemente homens (59,3% vs 45%; p = 0,003). A permanência hospitalar foi maior no Grupo MPD (média= 15,7 ± 25,7 vs. 11,8 ± 22,9 dias; p < 0,001), mas o implante não afetou morte por qualquer causa (26,7% vs. 25,6%; p = 0,80) nem morte cardiovascular (14,1% vs. 14,8%; p = 0,84). Por análise multivariada, a presença prévia de bloqueio de ramo direito (BRD) (OR, 6,19; 3,56-10,75; p ≤ 0,001), o uso da prótese CoreValve® (OR, 3,16; 1,74-5,72; p ≤ 0,001) e gradiente transaórtico basal > 50 mmHg (OR, 1,86; 1,08-3,2; p= 0,025) foram preditores de implante de MPD. O risco estimado de implante de MPD foi 4%, quando nenhum dos fatores de risco estava presente, e 63% na presença de todos. O modelo mostrou boa habilidade de prever a necessidade de MPD: 0,69 (IC95%: 0,64 - 0,74) na curva ROC. Subestudo de 287 ecocardiogramas durante o seguimento de 1 ano mostrou pior evolução da FEVE no Grupo MPD (p = 0,01). Conclusão: Em crianças de 6 a 11 anos, circunferência da cintura aumentada está associada à PA elevada, mesmo quando o IMC é normal. (Arq Bras Cardiol. 2017; [online].ahead print, PP.0-0)

ABSTRACT

BACKGROUND: The monitoring of healthcare quality indicators (HCQI) is a process of utmost importance in patient healthcare services. OBJECTIVE: To evaluate whether the monitoring of HCQI and the root-cause analysis improve the healthcare quality in acute myocardial infarction (AMI). METHODS: A cross-sectional and comparative analysis of HCQI was performed in patients with AMI in the years 2006 and 2007. Of the 1,461 patients admitted with chest pain, 172 (11.7%) had a diagnosis of AMI and were included in the analysis. RESULTS: The rate of primary angioplasty was 8.47% higher in 2007 (97.3%) when compared to that in 2006 (89.7%), but this difference was not statistically significant (p = 0.35). Moreover, there was no difference regarding the time of hospitalization (4 vs 5 days, p = 0.15) and the in-hospital mortality (7.8% vs 5.1%, p = 0.67) between 2007 and 2006, respectively. However, the time to the first troponin level was 27% shorter in 2007 (69 min.; 95%CI = 44-94 min.) when compared to 2006 (95 min.; 53-136 min.) (p = 0.025). The door-to-balloon time was 12% shorter (72 +/- 29 min. vs 109 +/- 85 min.; p = 0.03), the rate of ASA prescription at hospital discharge was 35% higher (94.7% vs 70.3%; p = 0.002) and the rate of PCA shorter than 90 minutes was 52% higher (78.3 vs 51.4%; p = 0.03) in 2007, when compared to 2006. CONCLUSION: Our results suggest that the strategy of monitoring the HCQI and the implementation of the root-cause analysis methodology can improve the healthcare process in patients with AMI.

INTRODUÇÃO: A via de acesso transfemoral é preferencial para o implante por cateter de bioprótese valvar aórtica. Entretanto, algumas situações, como a presença de doença vascular periférica, impossibilitam a utilização desse acesso. Nesses casos, o acesso por dissecção da artéria subclávia é uma alternativa para a realização do procedimento. Nosso objetivo foi avaliar a experiência brasileira com a utilização da artéria subclávia como via de acesso para o implante por cateter da bioprótese CoreValve®. MÉTODOS: Foram requisitos para o procedimento área valvar aórtica < 1 cm², ânulo valvar aórtico ≥ 20 mm e ≤ 27 mm (CoreValve® de 26 mm e 29 mm), aorta ascendente ≤ 43 mm e artéria subclávia com diâmetro ≥ 6 mm, isenta de lesões obstrutivas significativas, tortuosidade acentuada e calcificação excessiva. O acesso pela artéria subclávia foi obtido por dissecção cirúrgica e, sob visão direta, punção da artéria subclávia. Obtido o acesso arterial, empregou-se a técnica padrão. RESULTADOS: Entre janeiro de 2008 e abril de 2012, 8 pacientes com doença vascular periférica foram submetidos a implante de prótese CoreValve® pela artéria subclávia em 4 instituições. O procedimento foi realizado com sucesso em todos os casos, com redução do gradiente transvalvar aórtico médio de 46,4 ± 17,5 mmHg para 9,3 ± 3,6 mmHg (P = 0,0018) e melhora dos sintomas. Aos 30 dias e no seguimento de 275 ± 231 dias, 87,5% e 62,5% dos pacientes, respectivamente, apresentavam-se livres de complicações maiores (óbito, infarto do miocárdio, acidente vascular cerebral e cirurgia cardíaca de urgência). CONCLUSÕES: Na experiência brasileira, o acesso pela artéria subclávia mostrou-se seguro e eficaz como via alternativa para o implante por cateter da bioprótese CoreValve®.


BACKGROUND: Transfemoral access is the preferred approach for transcatheter aortic valve implantation. However, some situations, such as the presence of peripheral vascular disease, preclude the use of such access. In these cases, subclavian access is an alternative approach for this procedure. This study aimed at evaluating the Brazilian experience using the subclavian approach for transcatheter CoreValve® prosthesis implantation. METHODS: Aortic valve area < 1 cm², aortic valve ring ≥ 20 mm and ≤ 27 mm (26 mm and 29 mm CoreValve®), ascending aorta ≤ 43 mm and subclavian artery with a diameter ≥ 6 mm, without significant obstructive lesions, marked tortuosity and excess calcification were requisites for the procedure. The access through the subclavian artery was obtained by surgical dissection and, under direct vision, a subclavian artery puncture was performed. Once artery access was obtained, the standard technique was used. RESULTS: Between January 2008 and April 2012, 8 patients with peripheral vascular disease underwent CoreValve® prosthesis implantation through the subclavian artery in 4 institutions. The procedure was successful in all cases with reduction of the mean transvalvular pressure gradient from 46.4 ± 17.5 mmHg to 9.3 ± 3.6 mmHg (P = 0.0018) and improvement of symptoms. At 30 days and after 275 ± 231 days of follow-up, 87.5% and 62.5% of the patients, respectively, were free from major adverse events (death, myocardial infarction, stroke and urgent cardiac surgery). CONCLUSIONS: In the Brazilian experience, the subclavian access was a safe and effective alternative for transcatheter CoreValve® implantation.

ABSTRACT

A substituição cirúrgica da valva aórtica é o tratamento de eleição para pacientes com estenose aórtica sintomática acentuada. Entretanto, o risco cirúrgico aumenta expressivamente com o avançar da idade e com a associação de comorbidades. Nessa situação clínica, o implante por cateter de bioprótese valvar aórtica deve ser considerado uma alternativa terapêutica válida e eficaz. O propósito deste Consenso é oferecer uma revisão crítica do conjunto de evidências e dos avanços mais recentes relacionados ao implante por cateter de bioprótese valvar aórtica e sumarizaro estado da arte atual, com o intuito de melhor guiar a tomada de decisão terapêutica. A seleção dos pacientes para o implante por cateter de prótese valvar aórtica deve obedecer aos seguintes critérios: 1) presença de estenose valvar aórtica acentuada, sintomática, definida como orifício valvar aórtico com área < 1 cm² (ou < 0,6 cm²/m²); 2) idade > 75 anos e alta probabilidade de morbidade e mortalidade cirúrgicas pela presença de comorbidades; e 3) presença de condição anatômica e morfológica favorável para o procedimento por cateter. As evidências científicas atuais indicam que esse procedimento melhora os sintomas e reduz a mortalidade de pacientes com estenose aórtica e com contraindicação cirúrgica, quando comparado ao tratamento conservador. Adicionalmente, em pacientes com estenose aórtica acentuada e alto risco cirúrgico, o implante por cateter apresenta-se como alternativa terapêutica eficaz, capaz de alterar o curso natural da doença deforma equivalente ao tratamento cirúrgico convencional.


Surgical replacement of the aortic valve is the therapy of choice for patients with severe symptomatic aortic stenosis.However, surgical risk increases significantly with age and with the association of comorbidities. In this clinical context, transcatheter aortic-valve implantation must be consideredas a valid and effective therapeutic alternative. The purpose of this Consensus is to provide a critical review of all the evidence and recent advances related to transcatheter aortic valveimplantation and summarize the current state of the art, in order to better guide therapeutic decision-making. Patient selection for transcatheter aortic-valve implantation must meet the following criteria: 1) presence of severe symptomatic aortic valve stenosis, defined as aortic valve orifice area < 1 cm² (or < 0.6 cm²/m²); 2) age > 75 years and a high probability of surgical morbidity and mortality due to pre-existing comorbidities; and 3) the presence of anatomical and morphological conditions favorable for transcatheter interventions. Current scientific evidence indicates that thisprocedure improves symptoms and reduces mortality in patients with aortic stenosis who were not suitable candidates for surgery, as compared to standard therapy. Additionally, inpatients with severe aortic stenosis and high surgical risk, transcatheter aortic-valve implantation is an alternative effective treatment, able to alter the natural course of disease in a manner equivalent to conventional surgical treatment.

ABSTRACT

Introdução: A substituição cirúrgica da valva aórtica é o tratamento de eleição para pacientes com estenose aórtica acentuada. Entretanto, o risco cirúrgico aumenta expressivamente com o avançar da idade e com a associação de comorbidades. Recentemente, iniciou-se a experiência com o implante por cateter de biopróteses aórticas no Brasil. Justifica-se, portanto, a criação de um registro nacional para conhecimento dos resultados desse tipo de procedimento em nosso meio. Descrevemos o racional e o desenho do Registro Brasileiro de Implante de Bioprótese Aórtica por Cateter. Métodos: Trata-se de um registro multicêntrico, prospectivo, que incluirá 200 pacientes portadores de estenose valvar aórtica sintomática de alto risco cirúrgico submetidos a implante por cateter de bioprótese valvular aórtica em centros brasileiros. O desfecho primário do estudo é a mortalidade por qualquer causa aos 30 dias, 12 meses e 24 meses. Os desfechos secundários avaliados incluem, entre outros: 1) sucesso técnico do implante da bioprótese;2) mortalidade cardiovascular aos 30 dias, 12 meses e 24 meses; 3) desfecho combinado de segurança aos 30 dias; e 4) desfecho combinado de eficácia aos 12 meses e 24 meses. Conclusões: A análise dos resultados desse registro nacional permitirá avaliar os defechos do implante percutâneo de biopróteses aórticas em nosso meio.


Background: Surgical replacement of the aortic valve is the therapy of choice for patients with severe aortic stenosis.However, the surgical risk increases dramatically as age advances and with the association of comorbidities. Recently, transcatheter aortic valve implantation has been introduced in Brazil. Therefore, it was important to create a national registry to determine the outcomes of this procedure in our country. The rationale and design of the Brazilian Transcatheter Aortic Valve Implantation Registry is described.Methods: This is a multicenter prospective registry, including 200 patients with symptomatic aortic valve stenosis and high surgical risk submitted to transcatheter aortic valve implantation in Brazilian institutions. The primary endpoint of the study is all cause mortality at 30 days, 12 and 24 months. Secondary endpoints, among others, are: 1) technical success of transcatheter valve implantation; 2)cardiovascular mortality at 30 days, 12 and 24 months; 3) composite safety endpoint at 30 days; and 4) compositeefficacy endpoint at 12 and 24 months. Conclusions: The analysis of the results of this national registry will enable us to evaluate the outcomes of transcatheter aortic valve implantation in our country.

ABSTRACT

Introdução: Pacientes submetidos a intervenção coronária percutânea (ICP) em enxertos de veia safena caracteristicamente exibem maior risco de eventos cardiovasculares adversos maiores (ECAM). Foram avaliados a incidência e os preditores de ECAM no cenário atual, em que dispositivos de proteção distal e de aspiração de trombos e o uso de stents farmacológicos fazem parte da prática diária. Métodos: Neste estudo foram avaliados 69 casos consecutivos de pacientes com enxertos de veia safena, tratados com stents, entre janeiro de 2005 e dezembro de 2008. Foram avaliadas as características clínicas, angiográficas e relacionadas ao procedimento, bem como a incidência e preditores de ECAM na evolução tardia. Resultados: A média de idade dos pacientes foi de 72 + 10,2 anos, 79,7% eram do sexo masculino, 31,9% eram diabéticos, e 56,5% foram tratados na vigência de síndrome coronária aguda. Foram abordados 71 enxertos de veia safena, com lesões predominantemente localizadas no corpo (35,3%), tratadas mais frequentemente com stents farmacológicos (82,8%). Dispositivos de proteção distal foram utilizados em 31,9% e de aspiração de trombo em 1,4% dos pacientes, e em 30,4% foram utilizados inibidores da glicoproteína IIb/IIIa. No-reflow ocorreu em 8,7% e o sucesso do procedimento foi constatado em 89,9% dos casos. Na evolução tardia, ECAM, óbito, infarto agudo do miocárdio e revascularização do vaso-alvo ocorreram em 15,9%, 7,2%, 4,3% e 14,5%, respectivamente, e trombose de stent foi observada em 2,9% dos pacientes. Na regressão de Cox apenas o uso de stents não-farmacológicos foi associado a ECAM [hazard ratio (HR) 4,1, intervalo de confiança de 95% (IC 95%) 1,2-13,3; P = 0,02]. Conclusões: Pacientes com lesões em enxertos de veia safena, tratados percutaneamente, exibiram elevada taxa de eventos adversos a médio prazo e o uso de stents não-farmacológicos esteve associado a pior evolução.


Background: Patients undergoing percutaneous coronary interventions(PCI) in saphenous vein grafts tipically have a higher risk of major adverse cardiac events (MACE). MACE incidence and predictors were evaluated in the current scenario, where distal protection and thrombus aspirationdevices and the use of drug-eluting stents are part of the daily practice. Methods: Sixty-nine consecutive patients undergoing coronary stenting in saphenous vein grafts from January 2005 to December 2008 were evaluated. Clinical, angiographic and procedure-related variables were evaluated as well as the incidence and predictors of MACE in the late follow-up. Results: Mean age was 72 + 10.2 years, 79.7% were male, 31.9% were diabetic, and 56.5% presented withacute coronary syndromes. Seventy-one saphenous vein grafts were treated, with lesions located mainly in the body of the graft (35.3%) and more frequently treated with drug-elutingstents (82.8%). Distal protection devices were used in 31.9% and thrombus aspiration in 1.4% of the patients, and 30.4% received glycoprotein IIb/IIIa inhibitors. No-reflow was observed in 8.7% and procedure success was observed in 89.9% of the cases. In the late follow-up, MACE, death, acutemyocardial infarction and target vessel revascularization were observed in 15.9%, 7.2%, 4.3%, and 14.5%, respectively and stent thrombosis was observed in 2.9% of the patients.In the Cox regression analysis only the use of bare metal stents was associated with MACE [hazard ratio (HR) 4.1, 95% confidence interval (95% CI) 1.2-13.3; P = 0.02]. Conclusions: Patients with lesions in saphenous vein grafts treated by percutaneous interventions had a high rate of mid-term adverse events and the use of bare metal stents was associated to a worse clinical outcome.

ABSTRACT

FUNDAMENTO: A monitoração dos indicadores de qualidade no cuidado com a saúde (IQS) é um processo de fundamental importância na atenção à saúde dos pacientes. OBJETIVO: Avaliar se a monitoração dos IQS e a análise da causa-raiz melhoram a qualidade do cuidado no infarto agudo do miocárdio (IAM). MÉTODOS: Foi realizada uma análise transversal e comparativa dos IQS em pacientes com IAM nos anos de 2006 e 2007. Dos 1.461 pacientes admitidos com dor torácica, 172 (11,7 por cento) tiveram o diagnóstico de IAM e foram incluídos na análise. RESULTADOS: A taxa de angioplastia primária foi 8,47 por cento maior em 2007 (97,3 por cento) do que em 2006 (89,7 por cento), mas esta diferença não alcançou significado estatístico (p = 0,35). Também não houve diferença estatística no tempo de hospitalização (4 vs 5 dias, p = 0,15) e na mortalidade intra-hospitalar (7,8 por cento vs 5,1 por cento, p = 0,67) entre 2007 e 2006, respectivamente. No entanto, o tempo até o resultado da primeira troponina foi 27 por cento menor em 2007 (69 min.; IC 95 por cento = 44-94 min.) do que em 2006 (95 min.; 53-136 min.) (p = 0,025). O tempo porta-balão foi 12 por cento menor (72 ± 29 min. vs 109 ± 85 min.; p = 0,03), a taxa de prescrição de aspirina na alta foi 35 por cento maior (94,7 por cento vs 70,3 por cento; p = 0,002) e a taxa de APCP, menor do que 90 minutos, foi 52 por cento maior (78,3 vs 51,4 por cento; p = 0,03) em 2007, quando comparada a 2006. CONCLUSÃO: Nossos resultados sugerem que a estratégia de monitorar os IQS e a de implementação da metodologia de análise da causa-raiz melhora o processo de cuidado com a saúde no IAM.


BACKGROUND: The monitoring of healthcare quality indicators (HCQI) is a process of utmost importance in patient healthcare services. OBJECTIVE: To evaluate whether the monitoring of HCQI and the root-cause analysis improve the healthcare quality in acute myocardial infarction (AMI). METHODS: A cross-sectional and comparative analysis of HCQI was performed in patients with AMI in the years 2006 and 2007. Of the 1,461 patients admitted with chest pain, 172 (11.7 percent) had a diagnosis of AMI and were included in the analysis. RESULTS: The rate of primary angioplasty was 8.47 percent higher in 2007 (97.3 percent) when compared to that in 2006 (89.7 percent), but this difference was not statistically significant (p = 0.35). Moreover, there was no difference regarding the time of hospitalization (4 vs 5 days, p = 0.15) and the in-hospital mortality (7.8 percent vs 5.1 percent, p = 0.67) between 2007 and 2006, respectively. However, the time to the first troponin level was 27 percent shorter in 2007 (69 min.; 95 percentCI = 44-94 min.) when compared to 2006 (95 min.; 53-136 min.) (p = 0.025). The door-to-balloon time was 12 percent shorter (72 ± 29 min. vs 109 ± 85 min.; p = 0.03), the rate of ASA prescription at hospital discharge was 35 percent higher (94.7 percent vs 70.3 percent; p = 0.002) and the rate of PCA shorter than 90 minutes was 52 percent higher (78.3 vs 51.4 percent; p = 0.03) in 2007, when compared to 2006. CONCLUSION: Our results suggest that the strategy of monitoring the HCQI and the implementation of the root-cause analysis methodology can improve the healthcare process in patients with AMI.

ABSTRACT

This study aimed to analyze the effect of backpack load carriage over the spine. The studies that have investigated load carriage using backpacks have analyzed the lower limb dynamics and have not focused on the spine. In addition, the strategies applied by children may differ from adults as the relative weight differs between adolescents and adults. Methods: Ten schoolboys (13.9 ± 0.6 years-old; 1.53 ± 0.05 m; 44.9 ± 3.3 kg) volunteered to participate after their parents sign an informed consent form. Participants walked in a treadmill during approximately 15 minutes carrying a specially built backpack with a load that corresponded to 0.10 and 20 percent BW. A number of landmarks were placed over the subjects back and allowed reconstruction of the spinal profiles in the sagittal and frontal planes. The relation between the segments formed between acromium markers and the posterior superior iliac crest markers was used as a spinal rotation index. The maximum, minimal, mean and range of motion of the thoracic and lumbar regions and the whole spine were analyzed. The gait cycle was applied to normalize the gait cycle. Results indicated differences between the two loads (10 percent) BW and 20 percent BW. A number of changes in the spinal kinematics was found. In the saggital plane the range of movement was unaltered, although there was an increased in the flexion, which was interpreted as a compensatory strategy to counteract the effect of the load. These results are in line with the idea that the use of a backpack increases anterior leaning of the trunk, but are in disagreement with the notion that pronounced changes in the range of motion occur. Carrying a backpack did not produce a clear effect over the variables selected to identify thoracic and lumbar spine regions in the sagittal plane. Conclusion: Carrying a load that corresponded to 20 percent BW influences spinal kinematics in all planes of movements. These changes may impose an important change in posture and stress applied over the posterior aspect of the vertebral column. The slow walking speed used in the present study may have not induced large changes in the kinematics of the vertebral column as in other studies in which walking was performed in greater speeds. Thus, it is suggested that weight of the backpack is not the only factor that determines the movements of the vertebral column.


Este estudo visou analisar o efeito do carregamento de cargas por meio de mochilas sobre a coluna. Os estudos que investigaram o carregamento de cargas utilizando mochilas têm analisado a dinâmica de membros inferiores e não tem focado a coluna vertebral. Em adição, as estratégias aplicadas por crianças podem diferir visto que as cargas relativas podem diferir entre adolescentes e adultos. Métodos: dez escolares (13,9 ± 0,6 anos; 1,53 ± 0,05 m; 44,9 ± 3,3 kg) foram voluntários para participar do estudo após seus pais consentirem e assinarem um formulário livre e esclarecido. Os participantes caminharam em uma esteira. Durante aproximadamente 15 minutos carregando uma mochila especialmente feita que correspondia a 0,10 e 20 por cento do peso corporal. Um número de marcas corporais foi colocada nas costas dos sujeitos que permitiram a reconstrução dos perfis da coluna nos planos sagital e frontal. A relação entre os segmentos formados pelas marcas entre os acrômios e as cristas ilíacas foi usada como um índice de rotação da coluna. Os valores máximos, mínimos, médios e as amplitudes de movimento das regiões torácica e lombar e a coluna toda foram analisados. O ciclo da marcha foi normalizado pelo contato sucessivo de dois contatos do calcanhar com o solo. Resultados indicaram diferenças entre as cargas (10 e 20 por cento) PC). Um número de mudanças na cinemática da coluna foi encontrada. No plano sagital a amplitude de movimento permaneceu inalterada, todavia, houve um aumento na flexão a qual foi interpretada como uma estratégia compensatória em resposta ao efeito da carga. Os resultados estão em linha com a idéia que o uso de mochilas aumenta a inclinação anterior do tronco, mas em discordância com a noção que pronunciadas mudanças na amplitude de movimento ocorrem. O carregamento de cargas não produz um efeito claro sobre as variáveis selecionadas para identificar as alterações nas regiões lombar e torácica no plano sagital. Conclusão: o carregamento de cargas que correspondem a 20 por cento PC influenciam a cinemática da coluna em todos os planos de movimento. Essas mudanças podem impor importantes mudanças sobre a postura e o estresse aplicado sobre os aspectos anteriores e posteriores da coluna vertebral. A baixa velocidade de deslocamento usada no presente estudo podem não ter induzido grandes mudanças na cinematica da coluna vertebral, como demonstrado em outros estudos que usaram maiores velocidades de deslocamento. Desta forma, sugere-se que o peso da mochila não é o único ator que determina os movimentos da coluna vertebral.

ABSTRACT

Relata-se o caso de paciente octogenária, com infarto agudo do miocárdio (IAM) em evolução, que desenvolveu quadro inflamatório pulmonar agudo, compatível com diagnóstico de pneumonia em organização secundária ao uso de abciximab intracoronariano, em angioplastia percutânea coronariana (APC). Esse diagnóstico foi firmado por meio de alterações clínicas, radiográficas e tomográficas típicas e pela regressão dessas alterações após terapia com corticosteroide.


This report presents the case of an octogenarian female patient with acute myocardial infarction who developed an acute inflammatory pulmonary condition compatible with a diagnosis of secondary organizing pneumonia after intracoronary abciximab during percutaneous coronary angioplasty. This diagnosis was grounded on typical clinical, radiographic and tomographic alterations and the regression of these alterations after corticoid treatment.
