Validação prospectiva do escore de risco dante pazzanese em síndrome coronariana aguda sem supradesnivelamento do segmento ST / Prospective validation of the dante pazzanese risk score in non-ST-segment elevation acute coronary syndrome

FUNDAMENTO: Em Síndrome Coronariana Aguda (SCA) sem Supradesnivelamento do segmento ST (SST) é importante estimar a probabilidade de eventos adversos. Para esse fim, as diretrizes recomendam modelos de estratificação de risco. O escore de risco Dante Pazzanese (escore DANTE) é um modelo simples de estratificação de risco, composto das variáveis: aumento da idade (0 a 9 pontos); antecedente de diabete melito (2 pontos) ou acidente vascular encefálico (4 pontos); não uso de inibidor da enzima conversora da angiotensina (1 ponto); elevação da creatinina (0 a 10 pontos); combinação de elevação da troponina e depressão do segmento ST (0 a 4 pontos). OBJETIVO: Validar o escore DANTE em pacientes com SCA sem SST. MÉTODOS: Estudo prospectivo, observacional, com inclusão de 457 pacientes, de setembro de 2009 a outubro de 2010. Os pacientes foram agrupados em: muito baixo, baixo, intermediário e alto risco de acordo com a pontuação do modelo original. A habilidade preditiva do escore foi avaliada pela estatística-C. RESULTADOS: Foram 291 (63,7%) homens e a média da idade 62,1 anos (11,04). Dezessete pacientes (3,7%) apresentaram o evento de morte ou (re)infarto em 30 dias. Ocorreu aumento progressivo na proporção do evento, com aumento da pontuação: muito baixo risco = 0,0%; baixo risco = 3,9%; risco intermediário = 10,9%; alto risco = 60,0%; p < 0,0001. A estatística-C foi de 0,87 (IC 95% 0,81-0,94; p < 0,0001). CONCLUSÃO: O escore DANTE apresentou excelente habilidade preditiva para ocorrência dos eventos específicos e pode ser incorporado na avaliação prognóstica de pacientes com SCA sem SST.

BACKGROUND: In non-ST-segment elevation acute coronary syndrome (ACS), the likelihood of adverse events should be estimated. Guidelines recommend risk stratification models for that purpose. The Dante Pazzanese risk score (DANTE score) is a simple risk stratification model composed with the following variables: age increase (0 to 9 points); history of diabetes mellitus (2 points) or stroke (4 points); no use of angiotensin-converting-enzyme inhibitor (1 point); creatinine elevation (0 to 10 points); combination of troponin elevation and ST-segment depression (0 to 4 points). OBJECTIVE: To validate the DANTE score in patients with non-ST-segment elevation ACS. METHODS: Prospective, observational study including 457 patients, from September 2009 to October 2010. The patients were grouped in risk categories according to the original model score as follows: very low; low; intermediate; and high. The predictive ability of the score was assessed by using C-statistics. RESULTS: The sample comprised 291 (63.7%) men, the mean age being 62.1 years (SD=11.04). The event death or (re)infarction in 30 days was observed in 17 patients (3.7%). Progressive increase in the proportion of events was observed as the score increased: very low risk = 0.0%; low risk = 3.9%; intermediate risk = 10.9%; high risk = 60.0%; p < 0.0001. C-statistics was 0.87 (95% CI: 0.81-0.94; p < 0.0001). CONCLUSION: DANTE score showed an excellent capacity to predict the specific events, and can be incorporated to the prognostic assessment of patients with non-ST-segment elevation ACS.

Comportamento da síndrome coronariana aguda: resultados de um registro brasileiro / Acute coronary syndrome behavior: results of a Brazilian registry

FUNDAMENTO: O Brasil carece de registros multicêntricos publicados de síndrome coronariana aguda. OBJETIVO: O Registro Brasileiro de Síndrome Coronariana Aguda é um estudo multicêntrico nacional com objetivo de apresentar dados representativos das características clínicas, e manejo e evolução hospitalares dessa síndrome. MÉTODOS: Participaram 23 hospitais de 14 cidades. Foram elegíveis pacientes que se apresentaram com suspeita de síndrome coronariana aguda nas primeiras 24 horas, com quadro clínico sugestivo, associado a alterações eletrocardiográficas compatíveis e/ou marcadores de necrose. O seguimento foi realizado até o óbito ou a alta hospitalar. RESULTADOS: Entre os anos de 2003 e 2008, foram incluídos 2.693 pacientes com diagnóstico de síndrome coronariana aguda, sendo 864 (32,1%) mulheres. O diagnóstico final foi de angina instável para 1.141 (42,4%) pacientes, com mortalidade de 3,06% deles; de infarto agudo do miocárdio sem supradesnível de ST para 529 (19,6%) pacientes, com mortalidade de 6,8% deles; e de infarto agudo do miocárdio com supradesnível de ST para 950 (35,3%) pacientes, com mortalidade de 8,1% deles; tiveram diagnóstico não confirmado 73 (2,7%) pacientes, com mortalidade de 1,36% deles. A mortalidade global foi de 5,53%. O modelo de regressão logística múltipla identificou o gênero feminino (OR=1,45), o diabetes melito (OR=1,59), o índice de massa corporal (OR=1,27) e a intervenção coronariana percutânea (OR=0,70) como fatores de risco de óbito, para demografia e intervenções. Um modelo para óbito por complicações maiores identificou choque cardiogênico/Edema Agudo de Pulmão (OR=4,57), reinfarto (OR=3,48), acidente vascular cerebral (OR=21,56), sangramento grave (OR=3,33), parada cardiorrespiratória (OR=40,27) e classe funcional de Killip (OR=3,37). CONCLUSÃO: Os dados do Registro Brasileiro de Síndrome Coronariana Aguda não diferem de outros coletados fora do país. Seus achados poderão ajudar a promover um melhor planejamento e manejo do atendimento da síndrome coronariana aguda a nível público e privado.

BACKGROUND: Brazil lacks published multicenter registries of acute coronary syndrome. OBJECTIVE: The Brazilian Registry of Acute Coronary Syndrome is a multicenter national study aiming at providing data on clinical aspects, management and hospital outcomes of acute coronary syndrome in our country. METHODS: A total of 23 hospitals from 14 cities, participated in this study. Eligible patients were those who came to the emergency wards with suspected acute coronary syndrome within the first 24 hours of symptom onset, associated with compatible electrocardiographic alterations and/or altered necrosis biomarkers. Follow-up lasted until hospital discharge or death, whichever occurred first. RESULTS: Between 2003 and 2008, 2,693 ACS patients were enrolled, of which 864 (32.1%) were females. T he final diagnosis was unstable angina in 1,141 patients, (42.4%), with a mortality rate of 3.06%, non-ST elevation acute myocardial infarction (AMI) in 529 (19.6%), with mortality of 6.8%, ST-elevation AMI 950 (35.3%), with mortality of 8.1% and non-confirmed diagnosis 73 (2.7%), with mortality of 1.36%. The overall mortality was 5.53%. The multiple logistic regression model identified the following as risk factors for death regarding demographic factors and interventions: female gender (OR=1.45), diabetes mellitus (OR=1.59), body mass index (OR=1.27) and percutaneous coronary intervention (OR=0.70). A second model for death due to major complications identified: cardiogenic shock/acute pulmonary edema (OR=4.57), reinfarction (OR=3.48), stroke (OR=21.56), major bleeding (OR=3.33), cardiopulmonary arrest (OR=40.27) and Killip functional class (OR=3.37). CONCLUSION: The Brazilian Registry of Acute Coronary Syndrome data do not differ from other data collected abroad. The understanding of their findings may help promote better planning and management of acute coronary syndrome care in public and private health services.

Correlação dos escores de risco com a anatomia coronária na síndrome coronária aguda sem supra-ST / Correlation of risk scores with coronary anatomy in non-ST-elevation acute coronary syndrome

FUNDAMENTO:Há poucas publicações sobre a correlação entre escores de risco e anatomia coronária na síndrome coronária aguda (SCA). OBJETIVO: Correlacionar os escores de risco com a gravidade da lesão coronária na SCA sem supra-ST. MÉTODOS: Foram analisados 582 pacientes entre julho de 2004 e outubro de 2006. Avaliou-se a correlação entre os escores de risco TIMI, GRACE hospitalar e em seis meses com lesão coronária > 50%, por método não paramétrico de Spearman. Modelo de regressão logística múltipla foi realizado para determinar a habilidade preditiva dos escores em discriminar quem terá ou não lesão coronária > 50%. RESULTADOS: Foram 319 (54,8%) homens e a média de idade era 59,9 (± 10,6) anos. Correlação positiva foi observada entre a pontuação dos escores de risco e lesão coronária > 50% (escore de risco TIMI r = 0,363 [p < 0,0001]; escore GRACE hospitalar r = 0,255 [p < 0,0001]; escore GRACE em seis meses r = 0,209 [< 0,0001]). A área sob a curva ROC de cada escore para discriminar quem terá ou não lesão coronária > 50% foi: TIMI = 0,704 [IC95% 0,656-0,752; p <0,0001]; GRACE hospitalar = 0,623 [IC 95% 0,573-0,673; p < 0,0001]; GRACE em seis meses = 0,562 [IC95% 0,510-0,613; p = 0,0255]. Na comparação entre as áreas sob a curva ROC, tem-se: TIMI versus GRACE hospitalar: p = 0,01; TIMI versus GRACE em seis meses: p < 0,0001; GRACE hospitalar versus GRACE em seis meses: p = 0,0461. CONCLUSÃO: Os escores de risco se correlacionam com a gravidade das lesões coronárias, sendo o escore de risco TIMI o que demonstrou melhor habilidade preditiva.
