Resumo: Introdução e objetivos: Foi nosso objetivo reportar a evolução da angioplastia coronária no tratamento do enfarte agudo do miocárdio com supradesnivelamento do segmento ST (EAMCST), entre 2002‐2013. Métodos: Os dados prospetivos multicêntricos do Registo Nacional de Cardiologia de Intervenção (RNCI) e os dados oficiais da Direção Geral de Saúde (DGS) foram conjugados para estudar os procedimentos no EAMCST entre 2002 e 2013. Resultados: Em 2013 realizaram‐se 3524 angioplastias primárias (ICP‐P), representando um crescimento de 315% relativamente ao ano de 2002. Em 2002 a ICP‐P representava 16% do total de angioplastias coronárias, passando a representar 25% nos anos de 2012‐2013. Entre 2002‐2013 o número de procedimentos por milhão de habitantes aumentou de 106 para 338 e a angioplastia de recurso decresceu de 70,7 para 2%. Durante o período em análise, a utilização de stents eluidores de fármaco cresceu de 9,9 para 69,5%. Após 2008, observou‐se uma utilização crescente da trombectomia de aspiração, atingindo 46,7% em 2013. Os inibidores das glicoproteínas IIb/IIIa registaram um decréscimo no seu uso, sendo de 73,2% em 2002 e de 23,6% em 2013. O acesso radial cresceu de 8,3% em 2008 até 54,6% em 2013. Conclusões: Durante o período em análise, a taxa de angioplastia coronária por milhão de habitantes triplicou. A angioplastia de recurso foi ultrapassada pela angioplastia primária a partir de 2006. Observaram‐se novas tendências no tratamento do enfarte agudo do miocárdio com supradesnivelamento do segmento ST, salientando‐se a utilização de stents eluidores de fármacos e o acesso radial. Abstract: Introduction and Objectives: The aim of the present paper was to report trends in coronary angioplasty for the treatment of ST‐elevation myocardial infarction (STEMI) in Portugal. Methods: Prospective multicenter data from the Portuguese National Registry of Interventional Cardiology (RNCI) and official data from the Directorate‐General for Health (DGS) were studied to analyze percutaneous coronary intervention (PCI) procedures for STEMI from 2002 to 2013. Results: In 2013, 3524 primary percutaneous coronary intervention (p‐PCI) procedures were performed (25% of all procedures), an increase of 315% in comparison to 2002 (16% of all interventions). Between 2002 and 2013 the rate increased from 106 to 338 p‐PCIs per million population per year. Rescue angioplasty decreased from 70.7% in 2002 to 2% in 2013. During this period, the use of drug‐eluting stents grew from 9.9% to 69.5%. After 2008, the use of aspiration thrombectomy increased, reaching 46.7% in 2013. Glycoprotein IIb‐IIIa inhibitor use decreased from 73.2% in 2002 to 23.6% in the last year of the study. Use of a radial approach increased steadily from 8.3% in 2008 to 54.6% in 2013. Conclusion: During the reporting period there was a three‐fold increase in primary angioplasty rates per million population. Rescue angioplasty has been overtaken by p‐PCI as the predominant procedure since 2006. New trends in the treatment of STEMI were observed, notably the use of drug‐eluting stents and radial access as the predominant approach.

Copyright © The Author(s). 2018, Background: We aimed to evaluate the impact of thrombus aspiration (TA) during primary percutaneous coronary intervention (P-PCI) in ‘real-world’ settings. Methods: We performed a retrospective study, using data from the National Registry of Interventional Cardiology (RNCI 2006–2012, Portugal) with ST-elevation myocardial infarction (STEMI) patients treated with P-PCI. The primary outcome, in-hospital mortality, was analysed through adjusted odds ratio (aOR) and 95% confidence intervals (95%CI). Results: We assessed data for 9458 STEMI patients that undergone P-PCI (35% treated with TA). The risk of in-hospital mortality with TA (aOR 0.93, 95%CI:0.54–1.60) was not significantly decreased. After matching patients through the propensity score, TA reduced significantly the risk of in-hospital mortality (OR 0.58, 95%CI:0.35–0.98; 3500 patients). Conclusions: The whole cohort data does not support the routine use of TA in P-PCI, but the results of the propensityscore matched cohort suggests that the use of selective TA may improve the short-term risks of STEMI.

Introduction and Objectives: The aim of the present paper is to report trends in Portuguese interventional cardiology from 2004 to 2013 and to compare them with other European countries. Methods: Based on the Portuguese National Registry of Interventional Cardiology and on official data from the Directorate-General of Health, we give an overview of developments in coronary interventions from 2004 to 2013. Results: In 2013, 36 810 diagnostic catheterization procedures were performed, representing an increase of 34% compared to 2007 and a rate of 3529 coronary angiograms per million population. Coronary interventions increased by 65% in the decade from 2004 to 2013, with a total of 13 897 procedures and a rate of 1333 coronary interventions per million population in 2013. Primary percutaneous coronary intervention (PCI) increased by 265% from 2004 to 2013 (1328 vs. 3524), an adjusted rate of 338 primary PCIs per million, representing 25% of total angioplasties. Stents were the most frequently used devices, drug-eluting stents being used in 73% in 2013. Radial access increased from 4.1% in 2004 to 57.9% in 2013. Conclusion: Interventional cardiology in Portugal has been expanding since 2004. We would emphasize the fact that in 2013 all Portuguese interventional cardiology centers were participating in the National Registry of Interventional Cardiology, as well as the growth in primary PCI and increased use of radial access. Resumo: Introdução e objetivos: Foi nosso objetivo estudar as tendências da intervenção coronária percutânea entre 2004-2013 e comparar Portugal com outros países europeus. Métodos: Análise dos procedimentos coronários efetuados entre 2004-2013 com base num registo prospetivo, multicêntrico, voluntário, doente a doente – Registo Nacional de Cardiologia de Intervenção (RNCI) da Associação Portuguesa de Intervenção Cardiovascular da Sociedade Portuguesa de Cardiologia (APIC-SPC) – e dos dados oficiais publicados pela Direção Geral de Saúde (DGS). Resultados: Em 2013 realizaram-se 36 810 cateterismos diagnósticos (3529 coronariografias por milhão de habitantes), representando um aumento significativo de 34% relativamente ao ano de 2007 (p

The aim of this prospective registry is to evaluate a new algorithm designed to reduce the percentage of unnecessary ventricular pacing (%VP) in patients implanted with a dual-chamber pacemaker, through a dedicated pacing mode (called AAISafeR2) operating in AAI mode with back-up ventricular pacing in DDD mode, and to describe the incidence and distribution of atrioventricular (AV) block in this population. Investigators were free to assign patients to AAISafeR2 mode or to standard DDD (if AAISafeR was contraindicated, mainly due to permanent high-degree AV block). Patients underwent routine follow-up visits at 3, 6, 12, 18 and 24 months after implantation. At each follow-up visit, data were retrieved from pacemaker memories and analyzed to extract %VP and incidence of AV block. Up to December 2006, 158 patients (94 men, mean age 69 +/- 14 years) from nine Portuguese centers had been consecutively included. We also determined the distribution of AV block (according to the criteria used by the pacemaker to classify AV block and switch to DDD mode). AAISafeR was shown to be effective in reducing unnecessary VP in our patient population. The analysis also reveals a high incidence of paroxysmal AV block, often unknown at the time of implantation. There were no complications associated with AAISafeR programming.
