ABSTRACT

Introdução: Mulheres com infarto agudo do miocárdio (IAM) evoluem com maior mortalidade que os homens. A intervenção coronária percutânea (ICP) primária tem papel fundamental na redução da mortalidade no IAM. Buscou-se saber se há diferenças nos resultados hospitalares da ICP primária entre mulheres e homens. Métodos: Entre janeiro de 2002 e outubro de 2008, foram realizadas 428 ICPs primárias, das quais 125 (29,2%) em pacientes do sexo feminino. A técnica e a escolha do material durante o procedimento ficaram a cargo dos operadores. Todos os pacientes receberam terapia antiplaquetária dupla pré-procedimento. Resultados: Pacientes do sexo feminino eram mais idosas (65,1 anos vs. 59,2 anos; P < 0,001), apresentando-se mais frequentemente em Killip III/IV (11,2% vs. 3,3%; P = 0,002). O diâmetro dos stents foi menor nas mulheres (3,1 ± 0,4 mm vs. 3,3 ± 0,5 mm; P < 0,001), mas não foram observadas diferenças quanto à extensão desses stents (19,1 ± 6,5 mm vs. 18,7 ± 6,2 mm; P = 0,55), tempo porta-balão (159,4 ± 110,1 minutos vs. 138,9 ± 138,3 minutos; P = 0,19), uso de inibidores da glicoproteína IIb/IIIa (32% vs. 31%; P = 0,58) ou cateteres de aspiração de trombos (10,4% vs. 9,9%; P = 0,65). O sucesso do procedimento foi similar (97,1% vs. 96,7%) e as mulheres tenderam a evoluir com maior chance de óbito (5,6% vs. 2%; P = 0,06) e acidente vascular cerebral (0,8% vs. 0,3%; P = 0,09). A ocorrência de complicações vasculares maiores (6,4% vs. 5,6%; P = 0,49) foi semelhante nos dois sexos. Conclusões: Neste estudo as mulheres representam um terço dos pacientes submetidos a ICP primária, têm perfil clínico-angiográfico mais complexo e tendência para evoluir com maior chance de eventos cardiovasculares adversos maiores.


Background: Women with acute myocardial infarction (AMI) have higher mortality rates than men. Primary percutaneous coronary intervention (PCI) plays a major role in reducingAMI mortality rates. We tried to identify whether there are differences in in-hospital outcomes of primary PCI between women and men. Methods: From January 2002 and October2008, 428 primary PCIs were performed, 125 (29.2%) in female patients. The technique and device selection were at the operator’s discretion. All of the patients received dual antiplatelet therapy before the procedure. Results: Female patients were older (65.1 years vs. 59.2 years; P < 0.001), and more frequently presented Killip III/IV (11.2% vs.3.3%; P = 0.002). Stent diameter was smaller in women (3.1 + 0.4 mm vs. 3.3 + 0.5 mm; P < 0.001), but there wereno differences in stent length (19.1 + 6.5 mm vs. 18.7 + 6.2 mm; P = 0.55), door-to-balloon time (159.4 + 110.1minutes vs. 138.9 + 138.3 minutes; P = 0.19), use of glycoprotein IIb/IIIa inhibitors (32% vs. 31%; P = 0.58) orthrombus aspiration catheters (10.4% vs. 9.9%; P = 0.65). Procedure success was similar (97.1% vs. 96.7%) and women had a higher likelihood of death (5.6% vs. 2%; P = 0.06) and stroke (0.8% vs. 0.3%; P = 0.09). Major vascular complications (6.4% vs. 5.6%; P = 0.49) were similar in both genders. Conclusions: In this study women represent a third of the patients undergoing primary PCI, have a more complex clinical-angiographic profile and tend to evolve with a higher probability of major adverse cardiovascular events.

ABSTRACT

INTRODUÇÃO: O tabagismo é um importante fator de risco aterotrombótico, presente em um terço dos pacientes submetidos a intervenção coronária percutânea (ICP) em nosso serviço. O objetivo do presente trabalho foi analisar o perfil clínico-angiográfico e os resultados do procedimento nessa população. Método: No período de janeiro de 2002 a outubro de 2009, 5.466 ICPs foram realizadas, sendo 1.745 em pacientes tabagistas e 3.721 em não tabagistas. Todos os dados foram obtidos prospectivamente e os pacientes foram acompanhados durante a fase hospitalar. Resultados: No grupo de tabagistas, houve predomínio de sexo masculino (75,2 por cento vs. 62,1 por cento; P< 0,001), pacientes mais jovens (56,4 anos vs. 64,5 anos; P< 0,001), infarto agudo do miocárdio (IAM) com supradesnivelamento de ST (37,5 por cento vs. 19,5 por cento; P< 0,001), uniarteriais (56,5 por cento vs. 47 por cento; P< 0,001). Lesões longas (14,7 por cento vs. 12 por cento; P< 0, 001), bifurcações (5,6 por cento vs. 3,9 por cento; P= 0,002), lesões trombóticas...


BACKGROUND: Smoking is an important atherothrombotic risk factor, observed in one third of patients undergoing per-cutaneous coronary intervention (PCI) at our service. The objective of the present study was to analyze the clinical angiographic profile and the results of the procedure in this population. METHOD: From January 2002 to October 2009, 5,466 PCI procedures were carried out, of which 1,745 in smokers and 3,721 in non-smokers. All data were prospectively obtained and patients were followed-up during hospitalization. RESULTS: In the group of smokers, there was prevalence of males (75.2% vs. 62.1%; P < 0.001), younger patients (56.4 years vs. 64.5 years; P < 0.001), acute myocardial infarction (AMI) with ST-segment elevation (37.5% vs. 19.5%; P < 0.001), single-vessel disease (56.5% vs. 47%; P < 0.001), long lesions (14.7% vs. 12%; P < 0.001), bifurcations (5.6% vs. 3.9%; P = 0.002), thrombotic lesions (15.4% vs. 9%; P < 0.001), total occlusions (18.2% vs. 11.2%; P < 0.001) and greater use of IIb/IIIa inhibitors (2.5% vs. 1.6%; P = 0.04). Clinical success (96.5% vs. 96.1%; P = 0.5) as well as the need of emergency surgical revascularization (0.06% vs. 0.05%; P = 0.22), AMI (0.74% vs. 1.02%; P = 0.32) or death (0.63% vs. 0.73%; P = 0.69) were similar in both groups. Smokers, however, showed a trend towards a greater number of strokes during hospitalization (0.11% vs. 0.05%; P = 0.07). CONCLUSION: Smokers undergoing coronary angioplasty are eight years younger than non-smokers, present AMI with ST-segment elevation more frequently and have greater angiographic complexity. The use of modern technological resources allowed comparable in-hospital results, with the exception of stroke, whose incidence tends to be twice as high in smokers.

ABSTRACT

INTRODUÇÃO: O aumento da expectativa de vida da população e o risco de sangramento com o uso de trombolíticos têm permitido que pacientes casa vez mais idosos com infarto agudo do miocárdio sejam tratados pela intervenção coronária percutânea (ICP) primária. Analisamos os resultados hospitalares da ICP primária em pacientes com idade >ou igual a 80 anos. Métodos: No período de janeiro de 2002 a outubro de 2008, foram realizadas 4.788 ICPs, sendo 428 ICPs primárias. Destas, 34 foram em pacientes com idade > igual a 80 anos. Resultados: O sexo feminino (47,1 por cento vs. 27,7 por cento = 0,017), a classe funcional Killip IV (11,8 por cento vs. 4,1; P = 0,002) e o fluxo coronário TIMI 2/3 pré-ICP (60 por cento vs. 44,4 por cento; P = 0,032) foram mais frequentes nos idosos. Tabagismo (44,9 por cento vs. 8 por cento; P = 0,001)e uso de inibidores...


BACKGROUND: Improvements in life expectancy of the overall population and the risk of bleeding with thrombolytics have enabled very elderly patients with acute myocardial infarction to be treated by primary percutaneous coronary intervention (PCI). We analyzed the primary PCI in-hospital results in patients > 80 years of age. METHOD: From January 2002 to October 2008, 4,788 PCIs were performed, of which 428 were primary PCIs. Of these, 34 were performed in patients > 80 years of age and 394 in patients < 80 years of age. RESULTS: Females (47.1% vs. 27.7%; P = 0.017), Killip IV functional class (11.8% vs. 4.1%; P = 0.002) and pre-procedure TIMI 2/3 flow (60% vs. 44.4%; P = 0.032) were more frequent in elderly patients. Smoking (44.9% vs. 8%; P < 0.001) and use of glycoprotein IIb/IIIa inhibitors (32.5% vs. 11.7%; P = 0.04) were prevalent in the group < 80 years of age. There were no significant differences for door-to-balloon time (117.4 ± 125.7 minutes vs. 179.3 ± 169.8 minutes; P = 0.095), use of stents (91.2% vs. 98.2%; P = 0.78), or drug-eluting stents (0 vs. 2.8%; P = 0.067) and thrombus aspiration devices (11.7% vs. 12.2%; P = 0.65). Angiographic success rate was equal between the groups (97.1% vs. 96.5%; P > 0.99), but patients > 80 years old had a higher mortality rate (11.8% vs. 2.3%; P = 0.014). Reinfarction, stroke, major vascular complications and acute renal failure were similar between groups. CONCLUSION: PCI usually presents high angiographic success and low complication rates, reinforcing its role as a method of choice for reperfusion in the acute phase of myocardial infarction. Very elderly patients (> 80 years of age) have higher mortality rates, possibly due to the greater comorbidity in this group.
