Pericarditis constrictiva y arteria coronaria única: Una rara presentación

Abstract

Pericarditis constrictiva y arteria coronaria única: Una rara presentaciónConstrictive pericarditis and single coronary artery: Rare presentation La pericarditis constrictiva es la etapa final de un proceso inflamatorio que involucra con mayor asiduidad la capa parietal del pericardio y causa constricción. Las enfermedades autoinmunes son la etiología más frecuente 1 . La artritis reumatoide es un trastorno autoinmune sistémico de etiología desconocida. Se caracteriza por sinovitis crónica que afecta principalmente las articulaciones y también la membrana serosa del pericardio. La participación extraarticular es vista en los enfermos con genes HLA-DR1 y DR4 2,3 . El diagnóstico de pericarditis constrictiva requiere de la

Wellens Syndrome: impending acute myocardial infarction

“…1 It has a prevalence of 15% of all ACS. 2 This electrocardiographic pattern described exactly four decades ago, by de Zwaan et al, is especially seen in V2 and V3 leads, and is related to a poor prognosis due to the imminent risk of acute myocardial infarction (MI) and sudden death. 1 Wellens syndrome may present with or without pain, but its early recognition and management with an immediate reperfusion strategy is extremely important to avoid drastic consequences.…”

“…The electrocardiogram may show a type A WS pattern (biphasic T waves in right anterior chest leads, V2-V3), found in about 24% of cases, or a type B WS pattern (negative, deep, and symmetrical T waves in V2-V3, and occasionally in V1, V4, V5 and V6, are most frequent). [1][2][3]5 The differential diagnosis is varied. Other causes of altered T-wave morphology should be considered when approaching a patient with suspected WS, including brain "T's" due to central nervous system injury, left ventricular hypertrophy, right bundle-branch block, hypertrophic cardiomyopathy, pulmonary embolism, coronary vasospasm, and myocardial bridge.…”
