ABSTRACT
Objetivo: conocer el estado actual de la angioplastia transluminal coronaria primaria (ATC1ª) en Uruguay. Introducción: la ATC1ª es la estrategia de reperfusión preferida en las primeras 12 horas del infarto agudo de miocardio con elevación del segmento ST (IAMcST). Se practica en Uruguay desde la década de 1980, pero desde el año 2002 no se han publicado datos al respecto. Metodología: se analizó una cohorte histórica de pacientes tratados con ATC1ª en las primeras 24 horas de un IAMcST desde enero de 2004 a diciembre de 2012 en Uruguay, bajo cobertura financiera del Fondo Nacional de Recursos (FNR). Se analizaron en forma anonimizada, la procedencia, edad, sexo, tipo de cobertura asistencial, presencia de factores de riesgo vascular, clase de Killip y Kimball, uso de fibrinolíticos previos, presencia de criterios de reperfusión, características angiográficas y aspectos técnicos del procedimiento. La mortalidad se analizó para el mismo día del procedimiento, a los 30 días, al año y a los cinco años. Resultados: de un total de 26.058 angioplastias coronarias en el período, 7.742 fueron bajo el diagnóstico de IAMcST £ 24 horas (29,7%), en 7.337 pacientes, con una mediana de seguimiento de 4,3 años. La edad media fue 62,9 (DE 12,2 años, rango entre 18 y 95) y 69,1% fueron del sexo masculino. En Montevideo residían 5.130 pacientes (66,2%) y los 2.612 (33,7%) restantes en el interior del país. La vía radial (registrada a partir del 2010) se utilizó en el 88,9%. La mortalidad global fue de 2,1% (159/7.742 pacientes) para el mismo día del procedimiento; 7,7% (598/7.742 pacientes) a los 30 días; 12,2% (816/6.694 pacientes) al año, y 22,7% (699/3.079 pacientes) a los cinco años; 567 pacientes (7,3%) fueron pretratados con FBL, con una menor mortalidad al año para aquellos que tuvieron criterios de reperfusión (test de chi cuadrado, p=0,047). La enfermedad severa de un vaso presentó una mortalidad menor que la enfermedad severa de múltiples vasos ...
Objective: to know the current state of Primary Transluminal Coronary Angioplasty (PTCA) in Uruguay. Introduction: The PTCA is the preferred reperfusion strategy in the first 12 hours of acute myocardial infarction with ST segment elevation (STEMI). It has been used in Uruguay since the 80 ‘s, but since 2002 there has been no national published data on this topic. Methods: a historical cohort of patients treated with PTCA within 24 hours of STEMI from January 2004 to December 2012 in Uruguay under financial coverage of the “National Resources Fund” (FNR) were analyzed. Origin, age, sex, type of assistance coverage, presence of vascular risk factors, Killip-Kimbal class, previous use of fibrinolytics (FBL), evidence of reperfusion , angiographic features and technical aspects of the procedure were anonymized and analyzed. Mortality was analyzed for the same day of the procedure, at 30 days, one year and five years. Results: from a total of 26.058 coronary angioplasties in the period, 7.742 were under the diagnosis of STEMI £ 24 hours (29.7 %), in 7.337 patients with a median follow-up of 4.3 years. The mean age was 62.9 (SD 12.2 years , range 18 to 95) and 69.1 % were male. 5.130 patients (66.2 %) lived in Montevideo and 2.612 (33.7%) in the rest of the country. The radial approach (recorded since 2010) was used in 88.9 %. Overall mortality was 2.1 % (159/7.742 patients) for the same day of the procedure, 7.7% (598/7.742 patients) at 30 days , 12.2% (816/6.694 patients) at one year and 22.7 % (699/3.079 patients) at 5 years. 567 patients (7.3%) were pre-treated with FBL, with lower one year mortality for those who had evidence of reperfusion (Chi square test, p = 0.047). Severe one vessel disease had a lower mortality than severe multivessel disease and/or left main disease for each temporary cuts considered (Chi square test, p < 0.0001). Multivessel angioplasty was performed in 657 patients (8.5 %) and was an independent ...

Objetivo: determinar si los valores de la fracción de eyección ventricular (FEV) pre y post procedimiento se relacionan con una mejoría en la calidad de vida (CdV) de los pacientes que fueron sometidos a cirugía de bypass coronario vs. angioplastia coronaria. Diseño: estudio prospectivo observacional realizado en la clínica Guayaquil con 56 pacientes en quienes se llevó a cabo un procedimiento de revascularización coronaria, entre abril de 2010 y marzo de 2011. La CdV fue evaluada por medio del cuestionario SF-36v2 y la FEV mediante ecocardiografía; se hizo una reevaluación de los pacientes 4 a 8 semanas posteriores a la intervención. Resultados: de la muestra, 27 (48.2%) fueron tratados con angioplastia y 29 (51.8%) con cirugía de bypass. Se observó una mejoría en 7 de las 8 dimensiones de la salud, siendo mayor en el grupo de bypass coronario, aunque la diferencia no fue significativa (p>0.05); en cambio, la dimensión de dolor corporal mostró un incremento similar en ambas técnicas (p>0.05). En cuanto a la FEV, el mayor porcentaje de mejoría se obtuvo en aquellos sometidos a bypass (41.4% vs. 25%, p>0.05). No se encontró relación entre FEV y CdV (R2=0.27 para angioplastia, R2=0.07 para bypass). Conclusiones: ambas estrategias resultaron en una mejoría de la CdV durante las cuatro semanas de seguimiento; no se encontró una relación entre los cambios en la CdV y los valores de FEV en los pacientes.
Objective: to determine if the pre and post-procedure ventricular ejection fraction (VEF) values are associated with improved quality of life (QOL) of the patients who underwent coronary bypass surgery vs. coronary angioplasty. Design: prospective observational study conducted in the Guayaquil clinic with 56 patients who underwent a coronary revascularization procedure between April 2010 and March 2011. QOL was assessed using the SF-36v2 questionnaire and the VEF through echocardiography. Patients were re-assessed 4 to 8 weeks after the operation. Results: of the sample, 27 (48.2%) were treated with angioplasty and 29 (51.8%) with bypass surgery. Improvement was observed in 7 of the 8 health dimensions, being higher in the coronary bypass group, although the difference was not significant (p>0.05). The bodily pain dimension showed a similar increase in both techniques (p> 0.05). In terms of VEF, the highest percentage of improvement was obtained with those undergoing the bypass (41.4% vs. 25%, p> 0.05). No relationship was found between VEF and QOL (R2= 0.27 for angioplasty, R2= 0.07 for bypass). Conclusions: both strategies resulted in an improvement of QOL during the four-week follow up; no relationship was found between changes in QOL and FEV values in the patients.

@#Objective To assess the clinical safety and effectiveness of Boomerang closure device (Boomerang Percutaneous Femoral Access Management System) applied to patients undergoing coronary angiography (CAG) and/or percutaneous coronary intervention (PCI).Methods206 patients undergoing CAG and/or PCI were randomly divided into the heparin group and low molecular heparin (LWMH) group. The hemostasia success rate, hemostasia time, manual pressure time, device dwell time, complication rate and time to ambulation with each other of two groups were compared.ResultsThe heparin group and LWMH group both had high hemostasia success rate (98.06% and 99.03%), there wasn't significant difference between two groups. There was one patient with hematoma formation in the heparin group and LWMH group respectively. There was no significant difference between two groups in hemostasia time, manual pressure time, the device dwell time and time to ambulation.ConclusionAfter CAG and/or PCI, administered heparin and low molecular heparin is no effect on Boomerang closure device, and Boomerang closure device has a high hemostasia success rate.
ABSTRACT
Objective To evaluate the efficiency and safety of Percusurge guardwire distal protection system in coronary intervention in patients with acute myocardial infarction. Methods Three male patients with acute myocardial infarction were enrolled in the study. Primary angioplasty was performed for 2 of them, 2 and 7 hours after onset of the infarction symptom, respectively. Selective angioplasty was performed 17 days after infarction for the third case. Percusurge guardwire system was used during the procedure. Results Procedure success was achieved for all of the 3 cases. Lot of thrombus was sucked out. The infarct-related arteries had TIMI 3 flow at the end of the procedures. The patients′ symptoms were resolved soon after the procedure. Minor dissection was seen in one case which did not obstruct the distal flow and was left alone. Conclusion Percusurge guardwire system can be used safely and effectively in coronary intervention in the thrombus-laden arteries such as acute myocardial infarction.
ABSTRACT
The right chest electric admittance plethsmography (RCEAP) is a simple no invasive and reliable method in detecting the blood flow volume in the pulmomary artery and vein, an indirection of the left heart function. In this clinical study, the RCEAP, left heart catheterization for measurement of LVEDP and coronary angiogram and echocardiography for investigating the LVEF were performed on 34 patients with coronary heart disease. Of these 34 patients,24 had single or no left vessel lesion (Group A), 10 had left main coronary artery or its double branches lesions (Group B) ;8 underwent percutaneous trans-lumin coronary angioplasty (PTCA)and 10 had coronary artery bypass graft (CABG).The data obtained were analysed and compared to evaluate their respective diagnostic values. Correlation analysis demonstrated the values of hc/hz ratio, ha/hz ratio were moderated with LVEDP(r = 0. 68 or 0. 73,P
