RESUMO

AIM: Patients with diabetes mellitus are at high risk of adverse events after percutaneous revascularization, with no differences in outcomes between most contemporary drug-eluting stents. The Cre8 EVO stent releases a formulation of sirolimus with an amphiphilic carrier from laser-dug wells, and has shown clinical benefits in diabetes. We aimed to compare Cre8 EVO stents to Resolute Onyx stents (a contemporary polymer-based zotarolimus-eluting stent) in patients with diabetes. METHODS AND RESULTS: We did an investigator-initiated, randomized, controlled, assessor-blinded trial at 23 sites in Spain. Eligible patients had diabetes and required percutaneous coronary intervention. A total of 1175 patients were randomly assigned (1:1) to receive Cre8 EVO or Resolute Onyx stents. The primary endpoint was target-lesion failure, defined as a composite of cardiac death, target-vessel myocardial infarction, and clinically indicated target-lesion revascularization at 1-year follow-up. The trial had a non-inferiority design with a 4% margin for the primary endpoint. A superiority analysis was planned if non-inferiority was confirmed. There were 106 primary events, 42 (7.2%) in the Cre8 EVO group and 64 (10.9%) in the Resolute Onyx group [hazard ratio (HR): 0.65, 95% confidence interval (CI): 0.44-0.96; Pnon-inferiority < 0.001; Psuperiority = 0.030]. Among the secondary endpoints, Cre8 EVO stents had significantly lower rate than Resolute Onyx stents of target-vessel failure (7.5% vs. 11.1%, HR: 0.67, 95% CI: 0.46-0.99; P = 0.042). Probable or definite stent thrombosis and all-cause death were not significantly different between groups. CONCLUSION: In patients with diabetes, Cre8 EVO stents were non-inferior to Resolute Onyx stents with regard to target-lesion failure composite outcome. An exploratory analysis for superiority at 1 year suggests that the Cre8 EVO stents might be superior to Resolute Onyx stents with regard to the same outcome. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov: NCT03321032.

RESUMO

INTRODUCTION AND OBJECTIVES: Multiple clinical and echocardiographic parameters have been shown to have prognostic value in cases of left ventricular dysfunction. The purpose of this paper was to evaluate the relative predictive power of such parameters. METHODS: Ninety-one patients with systolic dysfunction were prospectively studied. Functional status was evaluated using the New York Heart Association classification and the 6-minute walking test. Other clinical and biochemical parameters were assessed, and an anatomic and functional echocardiographic study was performed. RESULTS: Mean follow-up was 16.5 months (SD: 6.95). Eighteen patients died and two underwent heart transplantation (cardiac death 22%). Multiple regression analysis showed that the only independent predictor of death was functional status. Functional classes I and II showed a 16-month mortality rate of 10%, class III 40% and class IV 83%. The mortality rate was 67% for patients who walked < 300 meters and 0% for those who reached > 500 meters. When echocardiographic results were analyzed separately, the only independent predictors of outcome were left atrial diameter and the E wave deceleration time. Deceleration times < 100 ms or atrial diameters > 5 cm were associated with a mortality rate of 46%. The correlation between E wave deceleration time and the walking test was r = 0.55, p < 0.0001. CONCLUSIONS: Functional status is the main predictor of outcome in patients with systolic dysfunction, whether assessed subjectively or estimated objectively by a walking test. Among echo-Doppler parameters, the deceleration time of the E wave and left atrial diameter gave similar prognostic information, although with less statistical significance. They can confirm or substitute the prognosis obtained by the functional classification.

RESUMO

Uno de los objetivos críticos de la estrategia de salud en la cardiopatía isquémica es la atención urgente del infarto agudo de miocardio con elevación del ST (IAMCEST) y más concretamente del síndrome coronario agudo con elevación del ST, en los que el tiempo asistencial es crítico. Esta inmediatez del tratamiento (ya sea mecánica o farmacológica) se debería reflejar en los resultados de morbimortalidad. En 2003, tras la evidencia científica de la necesidad de una revascularización mecánica (intervención coronaria percutánea primaria) en el infarto agudo de miocardio con elevación del segmento ST, se estableció esta opción terapéutica en el hospital de referencia de nuestra comunidad (programa de intervención coronaria percutánea primaria). En marzo de 2008, tras múltiples reuniones con diferentes estamentos y centros, se puso en marcha el Registro Comunitario de la Asistencia al Síndrome Coronario Agudo con Elevación del ST (Registro Código Infarto de las Illes Balears). Se realiza: a) detección y documentación de todos los casos diagnosticados de IAMCEST en la comunidad autónoma; b) evaluación sistemática de los resultados asistenciales del IAMCEST y su ajuste a los objetivos asistenciales (tiempos, morbimortalidad, complicaciones, tratamientos, etc.); c) identificación y abordaje de las desviaciones respecto a los objetivos; d) conocimiento exhaustivo e implicación en el proyecto de todos los dispositivos asistenciales, y e) seguimiento al mes, a los 6 meses y al año del alta hospitalaria tras el proceso agudo del IAMCEST (AU)


One of the main objectives of any health-care strategy for ischemic heart disease is to provide emergency treatment for acute myocardial infarction and especially for ST-elevation acute coronary syndrome (STEACS), where any delay in treatment is crucial. The speed with which treatment (whether mechanical or pharmacologic) can be implemented will be reflected in morbidity and mortality rates. In 2003, in response to scientific evidence that mechanical revascularization (i.e. primary percutaneous coronary intervention) is essential for ST-elevation acute myocardial infarction, this therapeutic technique was introduced at the referral hospital in our region (in a primary percutaneous coronary intervention program). In March 2008, after several meetings between various stakeholders and institutions, a regional trial of treatment for STEACS (i.e. the Balearic Islands myocardial infarction code trial) started. It involved: a) the identification and reporting of all patients diagnosed with STEACS in the region; b) a systematic analysis of the results of treatment for STEACS in comparison with treatment goals (e.g. treatment times, morbidity, mortality, complications and treatment provided); c) identifying and responding to any deviations from targets; d) thorough understanding of and involvement in the project by all parts of the health-care system, and e) follow-up 1 month, 6 months and 1 year after hospital discharge following the STEACS episode (AU)

RESUMO

Introducción y objetivos. Es conocido el valor pronóstico de múltiples parámetros clínicos y ecocardiográficos para la disfunción ventricular. Nuestro propósito fue estudiar esos parámetros para valorar su potencia predictiva relativa. Métodos. Estudiamos prospectivamente 91 casos de disfunción sistólica. Se valoró la situación funcional: clase funcional de la NYHA y la prueba de marcha de 6 min. Se analizaron criterios clínicos, analíticos, así como anatomofuncionales mediante ecocardiografía. Resultados. El seguimiento fue de 16,5 meses (DE: 6,95). De causa cardíaca murieron 18 pacientes y dos recibieron trasplante (muerte cardíaca: 22 por ciento). El análisis de regresión múltiple demostró como único predictor independiente de mortalidad la situación funcional. La clase funcional presentó una mortalidad a los 16 meses para las clases I-II, III y IV del 10, 40 y 83 por ciento. La prueba de la marcha presentó una mortalidad del 67 por ciento para quienes caminaron 500 m. Analizando sólo el ecocardiograma, los únicos predictores independientes fueron el tiempo de desaceleración de la E y el diámetro auricular izquierdo. Tiempos de desaceleración 5 cm indicaron una mortalidad del 46 por ciento. La correlación entre el tiempo de desaceleración de E y la duración de la marcha presentó un valor de r = 0,55, y de p < 0,0001. Conclusiones. La situación funcional es el dato pronóstico clave en la disfunción sistólica, ya de forma subjetiva, ya objetiva mediante la prueba de la marcha. El tiempo de desaceleración de la E y el tamaño auricular aportan una información pronóstica similar, aunque con menos significación estadística. Puede confirmar o sustituir la valorada según la clasificación funcional (AU)
