Quince años de intervencionismo percutáneo de la oclusión total coronaria crónica.: Experiencia, resultados y pronóstico clínico

Introduction and objectives: Chronic total coronary occlusion (CTO) is often a complex entity to deal with through a percutaneous coronary intervention, and the clinical benefits of successful recanalization still remain uncertain. Most registries feature data in limited time periods and do not reflect the impact that specific dedicated programs have on recanalization. Our study evaluates the results of a CTO program on a long-term period of time. Methods: All patients’ CTOs treated with percutaneous coronary interventions at our center from 2002 through 2017 were prospectively included in the registry. The clinical, angiographic and procedural data were collected, and clinical follow-up was conducted. Three consecutive periods of time were considered for the analysis of temporal trends. Results: A total of 424 CTOs (408 patients) were included. In 339 patients (80%) the procedure was successful. The rate of success increased over time, from 57% in 2002-2006 to 87% in 2012-2017 (P = .001). The most important independent predictor of procedural failure was lesion tortuosity. After a median follow-up of 39.7 months, the rates of major adverse cardiovascular events and cardiovascular mortality in success vs failed groups were 13.9% vs 24.7% (P = .015) and 3.6% vs 14.1% (P = .001), respectively. These were the independent predictors of cardiovascular mortality: chronic kidney disease, left anterior descending artery occlusion, and procedural failure. Conclusions: Our series shows a high rate of success in CTO recanalization, which has increased over the last few years due to greater expertise and improved program-specific technical advances. Several angiographic and procedural variables have been identified as predictors of failure. Successful procedures, especially on the left anterior descendent coronary artery, were associated with lower rates of cardiovascular mortality.Introducción y objetivos: La oclusión total coronaria crónica (OTC) es generalmente compleja de abordar con intervencionismo percutáneo y el beneficio clínico de su recanalización sigue siendo incierto. La mayoría de los registros aportan datos limitados en el tiempo y no reflejan el impacto de un programa específico para su tratamiento. Nuestro estudio evalúa los resultados de un programa de OTC a largo plazo. Métodos: Se incluyeron de forma prospectiva todos los pacientes tratados con un intento de revascularización percutánea de una OTC entre los años 2002 y 2017. Se obtuvieron datos clínicos, angiográficos, intraprocedimiento y del seguimiento. Se consideraron 3 periodos temporales consecutivos para el análisis. Resultados: Se incluyeron 408 pacientes (424 OTC). La desobstrucción tuvo éxito en 339 lesiones (80%). El éxito se incrementó con el tiempo, de un 57% en 2002-2006 a un 87% en 2012-2017 (p = 0,001). El predictor independiente más potente de procedimiento fallido fue la tortuosidad intralesional. Tras una mediana de seguimiento de 39,7 meses, las tasas de eventos adversos cardiacos mayores y de muerte cardiaca en los grupos de éxito y fracaso fueron del 13,9 frente al 24,7% (p = 0,015) y del 3,6 frente al 14,1% (p = 0,001), respectivamente. Los predictores independientes de mortalidad cardiaca fueron la insuficiencia renal crónica, la oclusión de la arteria descendente anterior y el fallo del procedimiento. Conclusiones: Nuestra serie muestra unas tasas elevadas de éxito en la recanalización de una OTC, incrementada en los últimos años debido a la experiencia y al desarrollo técnico del programa. Se han identificado numerosas variables clínicas y angiográficas como predictoras de fallo del procedimiento. El éxito en el procedimiento, en especial en la arteria descendente anterior, se asoció con una menor mortalidad cardiaca

Reperfusion therapies and in-hospital outcomes for ST-elevation myocardial infarction in Europe: The ACVC-EAPCI EORP STEMI Registry of the European Society of Cardiology

Aims: The aim of this study was to determine the contemporary use of reperfusion therapy in the European Society of Cardiology (ESC) member and affiliated countries and adherence to ESC clinical practice guidelines in patients with ST-elevation myocardial infarction (STEMI). Methods and results: Prospective cohort (EURObservational Research Programme STEMI Registry) of hospitalized STEMI patients with symptom onset <24 h in 196 centres across 29 countries. A total of 11 462 patients were enrolled, for whom primary percutaneous coronary intervention (PCI) (total cohort frequency: 72.2%, country frequency range 0-100%), fibrinolysis (18.8%; 0-100%), and no reperfusion therapy (9.0%; 0-75%) were performed. Corresponding in-hospital mortality rates from any cause were 3.1%, 4.4%, and 14.1% and overall mortality was 4.4% (country range 2.5-5.9%). Achievement of quality indicators for reperfusion was reported for 92.7% (region range 84.8-97.5%) for the performance of reperfusion therapy of all patients with STEMI <12 h and 54.4% (region range 37.1-70.1%) for timely reperfusion. Conclusions: The use of reperfusion therapy for STEMI in the ESC member and affiliated countries was high. Primary PCI was the most frequently used treatment and associated total in-hospital mortality was below 5%. However, there was geographic variation in the use of primary PCI, which was associated with differences in in-hospital mortality

The ESC ACCA EAPCI EORP acute coronary syndrome ST-elevation myocardial infarction registry

Aims: The Acute Cardiac Care Association (ACCA)-European Association of Percutaneous Coronary Intervention (EAPCI) Registry on ST-elevation myocardial infarction (STEMI) of the EurObservational programme (EORP) of the European Society of Cardiology (ESC) registry aimed to determine the current state of the use of reperfusion therapy in ESC member and ESC affiliated countries and the adherence to ESC STEMI guidelines in patients with STEMI. Methods and results: Between 1 January 2015 and 31 March 2018, a total of 11 462 patients admitted with an initial diagnosis of STEMI according to the 2012 ESC STEMI guidelines were enrolled. Individual patient data were collected across 196 centres and 29 countries. Among the centres, there were 136 percutaneous coronary intervention centres and 91 with cardiac surgery on-site. The majority of centres (129/196) were part of a STEMI network. The main objective of this study was to describe the demographic, clinical, and angiographic characteristics of patients with STEMI. Other objectives include to assess management patterns and in particular the current use of reperfusion therapies and to evaluate how recommendations of most recent STEMI European guidelines regarding reperfusion therapies and adjunctive pharmacological and non-pharmacological treatments are adopted in clinical practice and how their application can impact on patients' outcomes. Patients will be followed for 1 year after admission. Conclusion: The ESC ACCA-EAPCI EORP ACS STEMI registry is an international registry of care and outcomes of patients hospitalized with STEMI. It will provide insights into the contemporary patient profile, management patterns, and 1-year outcome of patients with STEMI
