CONSECUENCIAS CLINICAS, BIOQUIMICAS Y ELECTROFISIOLOGICAS DE LA OCLUSION AGUDA DE LAS ARTERIAS CORONARIAS AURICULARES EN EL SER HUMANO

Abstract

This thesis aims to test the hypothesis that atrial ischemia is itself a promoting factor to develop atrial arrhythmias. To answer this question, the study takes as research model the performance of coronary angioplasty, a common clinical scenario. The thesis consists of two distinct parts:_x000D_ In the first, the different anatomical patterns of atrial coronary circulation are reviewed and the scientific interest of the hypothesis is justified. Subsequently, the results of a retrospective cohort study are shown. This analysis determines, for the first time, the incidence and predictors of atrial branch occlusion during elective percutaneous coronary intervention._x000D_ In the second part, the results of a prospective cohort describe the clinical, biochemical and electrophysiological consequences of this complication. Thus, the incidence of myocardial infarction due to occlusion of atrial branch occlusion is determined and the risk of acute atrial arrhythmias during the early phase of this entity is clarified. Finally, the major findings of the thesis are compared with those found by other authors in previous literature and the scopes of the clinical implications are discussed.
