ABSTRACT

Abstract The incidence of mitral regurgitation in acute myocardial syndromes is variable. Echocardiographic evaluation is fundamental in making a proper diagnosis of mechanical complications and to offer timely treatment. We present a case of a 64-year-old male who was admitted to the ER in acute pulmonary edema. The electrocardiogram showed negative ST-segment deviation from V4-V6, positive ST-segment deviation in aVR. Multivessel disease with severe mitral regurgitation was seen in catheterization. A transthoracic echocardiogram revealed important mitral regurgitation showing the "tiger stripes" sign, seen in the presence of intracardial oscillating structures, in this case, suspected papillary muscle rupture. Echocardiographic evaluation is necessary in every case of myocardial infarction who present with new-onset mitral regurgitation. Treatment is complex and must be determined with an interdisciplinary group.

ABSTRACT

Abstract: Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times. Early pharmacological reperfusion of the culprit coronary artery and early coronary angiography (pharmacoinvasive strategy) can be the solution to the logistical problem that primary angioplasty rises. Several studies have demonstrated pharmacoinvasive strategy as effective and safe as primary angioplasty ST-elevation myocardial infarction, which is postulated as the choice to follow in communities where access to PPCI is limited. The Mexico City Government together with the National Institute of Cardiology have developed a pharmaco-invasive reperfusion treatment program to ensure effective and timely reperfusion in STEMI. The model comprises a network of care at all three levels of health, including a system for early pharmacological reperfusion in primary care centers, a digital telemedicine system, an inter-hospital transport network to ensure primary angioplasty or early percutaneous coronary intervention after fibrinolysis and a training program with certification of the health care personal. This program intends to reduce morbidity and mortality associated with myocardial infarction.


Resumen: México se ha posicionado como el país con mayor mortalidad atribuible al infarto del miocardio entre los países de la Organización de Cooperación y Desarrollo Económico. Esta tasa responde a múltiples factores, incluyendo una baja tasa de reperfusión y la ausencia de un sistema único y coordinado para la atención del infarto. Aun cuando la angioplastia es el método de reperfusión recomendado, requiere un sistema coordinado con personal entrenado y recursos materiales, condiciones que no siempre pueden ser alcanzadas. La reperfusión farmacológica temprana, seguida de angiografía coronaria temprana (estrategia farmacoinvasiva) es la solución al problema logístico que representa la angioplastia primaria. Múltiples estudios han demostrado que la estrategia farmacoinvasiva es tan segura y efectiva como la angioplastia primaria en el infarto agudo del miocardio con elevación del segmento ST, y se plantea como la estrategia de elección en comunidades donde el acceso a angioplastia está limitado por factores económicos, geográficos o socioculturales. El gobierno de la Ciudad de México en conjunto con el Instituto Nacional de Cardiología ha desarrollado un programa de estrategia farmacoinvasiva para asegurar la reperfusión temprana en el infarto del miocardio. El modelo comprende una red de atención en los 3 niveles, incluyendo un sistema de reperfusión farmacológica en centros de primer contacto, transferencia de electrocardiogramas mediante telemedicina entre el primer nivel y el Instituto Nacional de Cardiología, una red de transporte interhospitalario y un programa de entrenamiento y educación continua. El objetivo de este programa es reducir la morbilidad y la mortalidad asociadas al infarto del miocardio.

ABSTRACT

Introduction: Patients with ST elevation acute myocardial infarction (STEMI) comprise a heterogeneous population with respect to the risk for adverse events. Primary percutaneous coronary intervention (PCI) has shown to be better, mainly in high-risk patients. Objective: The purpose of this study was to determine if the Thrombolysis in Myocardial Infarction (TIMI) risk score for STEMI applied to patients undergo primary PCI identifies a group of patients at high risk for adverse events. Methods: We identifed patients with STEMI without cardiogenic shock on admission, who were treated with primary PCI. The TIMI and CADILLAC (Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications) risk scores were calculated to determine their predictive value for in hospital mortality. Patients were divided into two groups according to their TIMI risk score, low risk being 0-4 points and high risk ≥5 points, and the frequency of adverse events was analyzed. Results: We analyzed 572 patients with STEMI. The c-statistics predictive value of the TIMI risk score for mortality was 0.80 (p=0.0001) and the CADILLAC risk score was 0.83, (p=0.0001). Thirty-two percent of patients classifed as high risk (TIMI ≥5) had a higher incidence of adverse events than the low-risk group: mortality 14.8% vs. 2.1%, (p=0.0001); heart failure 15.3% vs. 4.1%, (p=0.0001); development of cardiogenic shock 10.9% vs. 1.5%, (p=0.0001); ventricular arrhythmias 14.8% vs. 5.9%, (p=0.001); and no-refow phenomenon 22.4% vs. 13.6%, (p=0.01). Conclusions: The TIMI risk score for STEMI prior to primary PCI can predict in hospital mortality and identifes a group of high-risk patients who might develop adverse events.


Introducción: Los pacientes con infarto agudo del miocardio con elevación del segmento ST (IAM CEST), son una población heterogénea por lo que toca al riesgo de eventos adversos. La intervención coronaria percutánea (ICP) primaria mostró ser mejor, principalmente en los pacientes de riesgo alto. Objetivo: La propuesta de este estudio fue determinar si la escala de riesgo de trombólisis en infarto del miocardio (TIMI) para IAM CEST, aplicado a los pacientes sometidos a ICP primaria, identifica a grupos de pacientes de riesgo alto de eventos adversos. Métodos: Se identificaron a pacientes con IAM CEST sin choque cardiogénico al ingreso, quienes fueron tratados con ICP primaria. Se calcularon las escalas de riesgo TIMI y CADILLAC (Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications), para determinar su valor predictivo de mortalidad intrahospitalaria. Los pacientes se dividieron en dos grupos de acuerdo a su escala de riesgo TIMI, riesgo bajo con 0-4 puntos y riesgo alto con ≥5 puntos, se analizó la frecuencia de eventos adversos. Resultados: Se analizaron 572 pacientes con IAM CEST. El valor predictivo del estadístico C de la escala de riesgo TIMI para mortalidad fue de 0.80 (p=0.0001), y la escala de riesgo CADILLAC fue de 0.83, (p=0.0001). El 32% de los pacientes clasificados como riesgo alto (TIMI ≥5), tuvo una alta incidencia de eventos adversos comparada con el grupo de riesgo bajo: la mortalidad 14.8% vs. 2.1%, (p=0.0001); falla cardiaca 15.3% vs. 4.1%, (p=0.0001); desarrollo de choque cardiogénico 10.9% vs. 1.5%, (p=0.0001); arritmias ventriculares 14.8% vs. 5.9%, (p=0.001), y fenómeno de no reflujo 22.4% vs. 13.6%, (p=0.01). Conclusiones: La escala de riesgo TIMI para IAM CEST, previo a ICP primaria puede predecir mortalidad intrahospitalaria e identificar a un grupo de pacientes de riesgo alto, los cuales pueden desarrollar eventos adversos.

ABSTRACT

Objetivo: Conocer las características, estrategia de tratamiento y mortalidad en pacientes con infarto agudo al miocardio y ruptura del septum interventricular posinfarto. Métodos: Se incluyeron 40 pacientes atendidos en un periodo de ocho años por infarto agudo al miocardio complicado con ruptura del septum interventricular posinfarto. Se utilizó ecocardiograma para confirmar la ruptura del septum interventricular posinfarto. Se evaluaron las características clínicas, el tipo de tratamiento y la mortalidad hospitalaria. Las variables se compararon con prueba U de Mann-Withney o prueba exacta de Fisher. Resultados: Edad 64 años (56 a 73), 67% hombres, 53% diabetes, 43% hipertensión, 40% tabaquismo. Los tratamientos fueron: conservador 45%, quirúrgico 38% o dispositivo Amplatzer 17%. La mortalidad general fue de 65%, con manejo conservador 54%, con cirugía 35% y con Amplatzer 12% (p = 0.02), y estuvo asociada a menor tiempo entre infarto agudo al miocardio y ruptura del septum interventricular posinfarto (p <0.001) y menor tiempo entre ruptura del septum interventricular posinfarto y tratamiento de cierre (p <0.001). Todos los pacientes con Killip Kimbal III o IV murieron. Conclusiones: Hasta el momento no existe una estrategia de manejo en la ruptura del septum interventricular posinfarto que demuestre ventajas sobre las demás. El único marcador de buen pronóstico podría ser el mayor tiempo entre la ruptura y el tratamiento de cierre. Es probable que la indicación de manejo de las guías internacionales no aplique para todos los pacientes y estos deban estratificarse de acuerdo a su estado hemodinámico.


Objective: To identify the characteristics, management strategy and mortality of patients with acute myocardial infarction (AMI) and rupture of ventricular septum (RVS). Methods: The study included 40 patients admitted during a period of 8 years, due to AMI complicated with RVS. RVS was confirmed by echocardiogram. The clinical characteristics, type of treatment and hospital mortality were evaluated. Variables were compared by Mann-Withney U tests or Fisher exact test. Results: Patients were 64 years old (56 - 73), 67% men, 53% diabetes mellitus, 43% hypertension, 40% smokers. Treatments were medical (45%), surgical (38%) or Amplatzer (17%). Overall mortality was 65%, in conservative group was 45%, in surgery group 38%, and Amplatzer group 17% (p = 0.02), it was associated to shorter time between AMI and RVS (p <0.001) and shorter time between and treatment (p <0.001). All patients with Killipp Kimbal III or IV died. Conclusions: Currently there is no management strategy in RSV with demonstrated advantage over other strategies. The only marker with good prognosis could be a long time between rupture and treatment. It is likely that the indication of management of International guidelines does not apply to all patients and these should be stratified according to their hemodynamic status.
