ABSTRACT

Resumen El momento adecuado para la administración de los inhibidores P2Y12 en pacientes con síndrome coronario agudo sin elevación del segmento ST es tema de debate desde hace dos décadas. Las recomendaciones actuales de las guías europeas sugieren administrar ácido acetilsalicílico y aguardar el momento de la cinecoronariografía, y una vez conocida la anatomía agregar un inhibidor P2Y12 solo en aquellos casos en que se programe una estrategia intervencionista precoz. Sin embargo, en el mundo real la estrategia de realizar o no pretratamiento es más compleja. Existe la incertidumbre respecto a que el paciente pueda acceder o no a una cinecoronariografía dentro de las 24 horas. En este escenario, el pretratamiento al ingreso de un paciente de riesgo intermedio o alto podría ser una opción si no va a ser estudiado con cateterismo dentro de las 2 a 4 horas del ingreso, analizando previamente el riesgo isquémico y de sangrado del paciente. Aún faltan estudios a gran escala que comparen estas dos opciones.


Abstract The appropriate time for the administration of P2Y12 inhibitors in patients with non-ST elevation acute coronary syndrome has been the subject of debate for two decades. The current recommendations of the European guidelines suggest administering acetylsalicylic acid and waiting for the coronary angiography and once the anatomy is known, adding a P2Y12 inhibitor only in those cases in which an early interventional strategy is scheduled. However, in the real world, the strategy to perform pretreatment or not is more complex. There is uncertainty regarding whether the patient can access a coronary angiography within 24 hours. In this scenario, pretreatment upon admission of intermediate or high-risk patients could be an option if it is not studied with catheterization within 2 to 4 hours of admission, previously analyzing the patient's ischemic and bleeding risk. Large-scale studies comparing these two options are still lacking.

ABSTRACT

This review is an update on antiplatelet therapy and its interaction with oral hypoglycemic agents in diabetic patients with ischemic heart disease. We summarize the main pathophysiological mechanisms that intervene in diabetic patients and that increase the ischemic risk, the effects of the combination of oral hypoglycemic agents, their antithrombotic effects and their interaction with antiplatelet, and finally the studies that demonstrated the benefits of antiplatelet in diabetic patients in different scenarios of ischemic heart disease. The different mechanisms of action involve improved glycemic control, increased bioavailability of nitric oxide, reduced oxidative stress and, for certain molecules, direct inhibition of platelet activation and aggregation.


Esta revisión consiste en una puesta al día del tratamiento antiplaquetario y la interacción que presenta con los hipoglucemiantes orales en pacientes diabéticos con cardiopatía isquémica. Resumimos los principales mecanismos fisiopatológicos que intervienen en el aumento del riesgo cardiovascular en este grupo, los efectos de la combinación entre los hipoglucemiantes orales, sus efectos antitrombóticos y su interacción con los antiplaquetarios y, por último, los trabajos que estudiaron los beneficios de los antiplaquetarios en pacientes diabéticos en diferentes escenarios de la cardiopatía isquémica. Los variados mecanismos de acción implican una mejora del control de la glucemia, del aumento de la biodisponibilidad del óxido nítrico, reducción del estrés oxidativo y, para ciertas moléculas, una inhibición directa de la activación y de la agregación plaquetaria.

ABSTRACT

High-output heart failure (HF) is an uncommon condition. This occurs when HF syndrome patients have a cardiac output higher than eight litres per minute. Shunts, such as fistulas and arteriovenous malformations are an important reversible cause. We present the case of a 30-year-old man who presented to the emergency department due to decompensated HF. Echocardiogram showed dilated myocardiopathy with high cardiac output (19.5 L/min calculated on long-axis view). He was diagnosed with arteriovenous malformation by computed tomography (CT) and subsequent angiography, and a multi-disciplinary team decided to perform endovascular embolisation with ethylene vinyl alcohol/dimethyl sulfoxide at different times. The transthoracic echocardiogram showed a significant decrease in cardiac output (9.8 L/min) and his general condition improved significantly.

ABSTRACT

OBJECTIVES: We report a case of a man with tamponade decompression syndrome following pericardial drainage. DATA SOURCES: ICU - Montreal Heart Institute. STUDY SELECTION: Case report. DATA EXTRACTION: Clinical and surgical records. DATA SYNTHESIS: None. CONCLUSIONS: Our case adds further concerns in supporting a patient with tamponade decompression syndrome, including mechanical circulatory support, due to the reversible nature of this condition.
