ABSTRACT
INTRODUÇÃO: A estratificação de risco, pré intervenção coronária percutânea, é um elemento-chave para auxiliar na tomada de decisão oferecendo o nível de expectativas de resultados imediatos e tardios. Esta investigação tem como objetivo desenvolver o escore DESIRE para predizer o risco de ocorrência de eventos cardíacos maiores(ECM) em pacientes(P) submetidos ao implante de stents farmacológicos(SF) na prática clínica diária. MÉTODOS: Desde 2002 todos os pacientes consecutivos, tratados com 1 SF , foram incluídos no Registro DESIRE (Drug-Eluting Stents In REal world), não-randomizado. Desenvolvemos o escore DESIRE, a partir da análise retrospectiva dos dados dos P incluídos entre janeiro de 2007 e dezembro de 2012 uma vez que esta população representava melhor a prática contemporânea da cardiologia intervencionista. As associações das variáveis com os eventos foram testadas pelos testes chi-quadrado e t de Student. Devido às diferenças entre as fases analisadas, decidimos por dois modelos de predição de riscos: hospitalar (Regressão logística) e tardio (Cox) estimando o tempo até o primeiro evento. Após o desenvolvimento, o escore foi aplicado prospectivamente nos pacientes incluídos entre janeiro de 2013 e dezembro de 2014. As estimativas de risco obtidas foram comparadas às taxas de ECM observadas, validando o escore DESIRE nas duas fases...

BACKGROUND: Appropriate use criteria (AUC) for coronary revascularization were developed to deliver high-quality care; however, the prognostic impact of these criteria remains unclear. We sought to assess the outcomes of patients treated with second-generation drug-eluting stent (DES) classified according to the updated American College of Cardiology Foundation/American Heart Association/Society for Cardiac Angiography and Intervention AUC for percutaneous coronary intervention (PCI). METHODS: Between January 2012 and December 2013, a total of 1108 consecutive patients treated only with second-generation DES were categorized according to the AUC in three groups, using the new proposed terminology: appropriate ("A"); uncertain ("U"); and inappropriate ("I"). Major adverse cardiac event (MACE, defined as cardiac death, non-fatal myocardial infarction, and ischemia-driven target-lesion revascularization) and stent thrombosis up to 3 years were compared. RESULTS: PCI was categorized as A in 33.8%, U in 46.8%, and I in 19.4% of all cases. PCI-A patients had a higher prevalence of acute coronary syndromes, while PCI-I involved the treatment of more diabetics and patients with stable coronary disease. There were no differences in procedural complications among the three groups, with comparable rates of in-hospital MACE (9.3% for A vs 9.0% for U vs 7.0% for I; P=.70) and 2-year MACE (13.9% for A vs 9.0% for U vs 8.6% for I; P=.40). In the multivariable analysis, AUC classification was not associated with adverse outcomes...

INTRODUÇÃO: Os stents farmacológicos (SFs) modificaram a prática intervencionista contemporânea, permitindo abordar cenários clínicos e angiográficos progressivamente mais complexos. O objetivo deste estudo foi demonstrar as modificações ocorridas nos últimos 10 anos na forma de indicar e de realizar a intervenção coronária percutânea (ICP) em um hospital privado, terciário, do Estado de São Paulo. MÉTODOS: O DESIRE é um registro unicêntrico, prospectivo, com o objetivo de acompanhar os desfechos agudos e tardios de pacientes consecutivos tratados com SFs. RESULTADOS: No período de 2002 a 2011, foram incluídos 4.229 pacientes, com média de idade de 64,3 ± 11,2 anos, 23% eram do sexo feminino e 30,5%, diabéticos. Foram tratadas 6.518 lesões, das quais 61,5% eram do tipo B2/C. Os SFs foram utilizados em proporção crescente, alcançando penetração de 88,4% em 2011. A complexidade das ICPs aumentou, sendo tratada no último ano 1,76 lesão por paciente, com média de 1,89 SF. O escore SYNTAX, no período de 2002-2006, foi de 12,3 ± 4,4, enquanto entre 2007-2011 elevou-se para 15,7 ± 4,7. O seguimento clínico foi obtido em 98,2% dos pacientes, com mediana de 5,2 anos, sendo observada, nesse período, revascularização da lesão-alvo em 5%, infarto do miocárdio em 6,7% e óbito cardiovascular em 4,1% dos pacientes. A trombose do stent ocorreu em 2,4% dos casos. CONCLUSÕES: Nossos resultados demonstram marcante incremento no perfil de complexidade dos pacientes tratados nos últimos 10 anos e, ao mesmo tempo, confirmam a efetividade a longo prazo dos SFs, a despeito dos perfis clínico e angiográfico tratados.
BACKGROUND: Drug-eluting stents (DES) have changed contemporary interventional cardiology practice, enabling the approach of increasingly more complex clinical and angiographic scenarios. The objective of this study was to demonstrate the changes observed in the last 10 years in the indication and practice of percutaneous coronary intervention (PCI) at a tertiary private hospital in the State of São Paulo. METHODS: DESIRE is a single-center prospective registry aiming at following the acute and late outcomes of consecutive patients treated by DES. RESULTS: From 2002 to 2011, 4,299 patients were included, with mean age of 64.3 ± 11.2 years, 23% were female and 30.5 were diabetic. The total number of lesions treated was 6,518 of which 61.5% were type B2/C. During the course of the study, DES were progressively more used, reaching a penetration of 88.4% in 2011. The complexity of PCIs has increased and in the past year 1.76 lesions per patient were treated with an average of 1.89 DES. The SYNTAX score increased from 12.3 ± 4.4 (2002-2006) to 15.7 ± 4.7 (2007-2011). Clinical follow-up was obtained in 98.2% of the patients, with a median of 5.2 years, and during this period target-lesion revascularization rate was 5%, myocardial infarction was 6.7% and cardiovascular death was 4.1%. Stent thrombosis was observed in 2.4% of the cases. CONCLUSIONS: Our results showed a marked increment in the complexity profile of patients treated in the last 10 years and at the same time confirm the long-term effectiveness of DES, despite the clinical and angiographic profile of patients.

BACKGROUND: Despite the increasing number of elderly people, this high-complexity subset of patients is often excluded from randomized trials of percutaneous coronary intervention (PCI) and, therefore, limited data are available about their outcomes after drug-eluting stent (DES) implantation. We sought to compare the very long-term (> 1 year) clinical follow up of octogenarians treated with DES compared to younger individuals. METHODS: The DESIRE registry is a prospective, nonrandomized, single-center registry with consecutive patients treated solely with DES between May 2002 and May 2007. The only exclusion criteria were the treatment of patients in the setting of acute myocardial infarction (MI) (< 72 hours) and lesions located in non-native coronary arteries. The primary endpoint was the occurrence of combined major adverse cardiac events (MACE) (cardiac death, non-fatal MI and target vessel revascularization) in-hospital and in very long term (> 1 year) follow up. Patients were clinically evaluated at 1, 3 and 6 months and then annually up to 5 years. Stent thrombosis was classified according to the ARC definition. RESULTS: A total of 1,364 patients matched the inclusion/exclusion criteria and were sorted into 3 groups according to their ages: Group I = patients < 70 years of age (n = 914); Group II = patients greater than or equal to 70 and < 80 years of age (n = 334); and Group III = patients greater than or equal to 80 years old (n = 116). As expected, octogenarians had significantly more comorbid and complex anatomic lesion presentation. Nevertheless, in-hospital success was comparable among the 3 groups. Long-term (2.6 +/- 1.2 years) follow up was obtained from 97% of the total population and showed equivalent cumulative MACE in all age ranges (7.6% for < 70 years old vs. 5.4% for septuagenarians and 6.0% for octogenarians, p = 0.7). However, octogenarians had markedly more cardiac death, reflecting the severity of their comorbidity and the natural evolution of coronary disease. Of note, very few cases of stent thrombosis were noticed in the overall population (20 patients, 1.5%), with no difference among the groups. CONCLUSIONS: PCI with DES represents an efficient and safe approach to treat coronary artery disease in the elderly, with low rates of combined MACE comparable to other age ranges.

Fundamentos: O diabetes melito está relacionado à ocorrência de desfechos desfavoráveis após intervenções coronárias percutâneas. Os stents farmacológicos podem conferir melhor evolução tardia a esse subgrupo de pacientes. O objetivo deste estudo foi avaliar o desempenho desses instrumentais em pacientes diabéticos. Métodos: O DESIRE é um registro unicêntrico, prospectivo, que inclui 2,365 pacientes tratados consecutivamente com stents farmacológicos, entre maio de 2002 e janeiro de 2008. Para a presente análise foram excluídos pacientes com diagnóstico de infarto do miocárdio, aqueles com lesão tratada em ponte de safena e os com período de evolução inferior a 6 meses. Resultados: Assim 1.705 pacientes foram divididos em dois grupos: não-diabéticos (n igual 1.211 pacientes, 71,1 por cento) e diabéticos (n igual 494 pacientes, 28,9 por cento),sendo 109 (6,4 por cento) pacientes em uso de insulina. Dentre os diabéticos havia mais idosos (64,8 mais ou menos 9,8 anos vs. 63,4 mais ou menos11,7 anos; p igual 0,025), mulheres (28,9 por cento vs. 22,5 por cento; p igual 0,005), obesos (35,2 por cento vs. 23,5 por cento; p menor 0,001)...
Background: Diabetes mellitus is related to the occurrence of unfavorable outcomes after percutaneous coronary interventions. Drug-eluting stents can confer a better late evolution to this subgroup. The aim of this study was to assess the performance of these devices in diabetic patients. Methods: The DESIRE is a single-center, prospective registry that included 2,365 consecutive patients treated with drug-eluting stents between May 2002 and January 2008. For the present analysis, patients with a diagnosis of acute myocardial infarction, those with saphenous vein grafts lesions and those within 6 months of the index procedure, were excluded. Results: Therefore, 1,705 patients were divided into two groups: non-diabetics (n = 1,211 P/71.1%) and diabetics (n = 494 P/28.9%), of which 109 P (6.4%) were insulin-dependent. Among the diabetics there was a higher number of older people (64.8 ± 9.8 years old vs. 63.4 ± 11.7 years old; p = 0.025), females (28.9 vs. 22.5%; p = 0.005), patients with obesity (35.2 vs. 23.5%; p < 0.001), hypertension (86.6 vs. 73.7%; p < 0.001), multi-vessel disease (63.4 vs. 54.4%; p = 0.001), small-vessel disease (2.70 ± 0.51 mm vs. 2.75 ± 0.42 mm; p < 0.001) and calcified lesions (32.3 vs. 27.1%; p = 0.009).In the late clinical follow up (2.2 ± 1.1 years), the combined cardiac events occurred more frequently in the diabetic patients (9.8 vs. 7.0%; p = 0.048). The multivariate analysis showed that diabetes mellitus (OR = 1.45; 95% confidence interval 1.0 to 2.1) and the presence of a calcified lesion
