ABSTRACT
Resumen Introducción: La ectasia coronaria (EC) es una remodelación patológica con una prevalencia mundial baja. Se define como una dilatación difusa mayor a 1.5 veces el diámetro de los segmentos adyacentes de esta o diferentes arterias coronarias. Objetivo: Documentar las características clínicas y angiográficas, y el tratamiento médico que reciben los pacientes con diagnóstico de EC en el Instituto Nacional de Cardiología (INC). Métodos: Estudio de tipo transversal con diseño no experimental descriptivo, con un muestreo por conveniencia no probabilístico. Resultados: De 69 pacientes que asistieron al INC con diagnóstico de EC la mayor parte eran hombres, con una media de edad de 56 ± 11 años, el factor de riesgo coronario más común en los pacientes con EC fue el tabaquismo, en 40 (58%); se asoció un infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en 45 (65.2%), de localización frecuente en la cara inferior 18 (40%), relacionado con la arteria más afectada, la coronaria derecha 48 (69.6%), seguida de la circunfleja 39 (56.5%). Destaca el uso preferente de la terapia antiplaquetaria dual con anticoagulante (APD+ACO) en 40 (58%) al egreso de cada paciente del INC. Conclusión: La EC es una remodelación patológica no infrecuente en el INC. En este estudio se evidenció que el SCA-IAMCEST es la manifestación más típica de la EC, la coronariografía diagnóstica identificó un Markis tipo 3, por lo que se esperaría una tasa baja de mortalidad y recurrencia de eventos cardiovasculares y a pesar de no existir un consenso sobre la terapia ideal, en el INC se prefiere el tratamiento individualizado, recomendando modificación en el estilo de vida y empleando como tratamiento médico el uso de la triple terapia (APD+ACO) solo al momento de egreso del paciente.
Abstract Introduction: Coronary Ectasia (CE) is a pathological remodeling with a low worldwide prevalence. It is defined as a diffuse dilatation greater than 1.5 times the diameter of the adjacent segments of the same or different coronary arteries. Objective: To document the clinical and angiographic characteristics, and medical treatment at the discharge of patients diagnosed with coronary ectasia who attended the National Institute of Cardiology (INC). Methods: Cross-sectional study with a non-experimental descriptive design, with a non-probabilistic convenience sampling. Results: Of 69 patients who attended the INC with a diagnosis of CD, most were men, with a mean age of 56 + 11 years, the most common coronary risk factor in patients with CE was smoking 58% (40); it was associated mostly with an acute myocardial infarction ST-segment elevation (STEMI) 65.2% (45), of frequent location in the lower face 40% (18), correlated with the most affected artery is the Right Coronary Artery (CD) 69.6% (48), followed by the circumflex (Cx) 56.5% (39). A mean LVEF of 47 + 9.72 was evident within the ventricular function. As well as the preferential use of dual antiplatelet therapy with anticoagulant (DAP + OAC) in 58% (40) at the discharge of each patient from the INC. Conclusion: CE is a not uncommon pathological remodeling in INC. This study showed that STEMI is the most typical manifestation of CE, diagnostic coronary angiography identified a type 3 Markis, so a low rate of mortality and recurrence of cardiovascular events would be expected, and despite the lack of consensus on the ideal therapy, at the INC individualized treatment is preferred, recommending lifestyle changes, and using triple therapy (DAP + OAC) as a medical treatment only at the time of patient discharge.
ABSTRACT
Los aneurismas de las arterias coronarias son muy raros. Ocurren más frecuentemente en la arteria coronaria derecha, seguidos por los de la arteria coronaria descendente anterior y circunfleja. Los aneurismas del tronco de la arteria coronaria izquierda son aún más raros. La enfermedad más frecuentemente asociada a esta entidad es la aterosclerosis coronaria con estenosis severas en las zonas adyacentes a los mismos. La sífilis terciaria con manifestaciones cardiovasculares puede producir aortitis, insuficiencia aórtica, miocarditis y aneurismas o estenosis de las coronarias. El estándar de oro para el diagnóstico de los aneurismas coronarios es la angiografía coronaria y su tratamiento dependerá de la etiología y localización de los mismos. El tratamiento antibiótico en sífilis terciaria es imperativo; sin embargo no existe consenso en cuanto al tratamiento de los aneurismas coronarios en ausencia de obstrucciones. El tratamiento a largo plazo con anticoagulantes orales puede estar recomendado en este tipo de pacientes.
Aneurysms of the coronary arteries are very rare. Occur more frequently in the right coronary artery, followed by those of the left anterior descending coronary artery and circumflex. Aneurysms of the left main coronary artery are even more rare. The disease most often associated with this pathology is coronary atherosclerosis with severe stenosis in the section adjacent to them. Tertiary syphilis with cardiovascular manifestations can produce aortitis, aortic insufficiency, myocarditis and aneurysms or coronary stenosis. The gold standard for diagnosis of coronary aneurysms is coronary angiography and treatment depends on the etiology and location thereof. Antibiotic treatment in tertiary syphilis is imperative; however there is no consensus on the treatment of coronary aneurysms in the absence of obstructions. The long-term treatment with oral anticoagulants may be recommended in these patients.

O tratamento prolongado com anticoagulantes orais pode ser recomendado nestes pacientes.
ABSTRACT
Kawasaki disease (KD) is an acute systemic vasculitis of unknown aetiology that has largely replaced rheumatic heart disease as a cause of acquired heart disease in children of many developed countries. We report a case of incomplete KD in a threemonth- old girl. The diagnosis of incomplete KD was made after exclusion of conditions with similar presentation. She was treated with intravenous immunoglobulin following which she made an uneventful recovery but demonstrated thrombocytosis in the second week of convalescence. It is important for the treating physicians to become aware of the incomplete KD as prompt diagnosis and early treatment of these patients with intravenous immunoglobulin is vital for the prevention of lethal coronary complications. Physicians need to have a "high index of suspicion" for KD and even, higher for IKD.
