Nexo de causalidade nos acidentes de trabalho

: o problema do enfarte do miocárdio

Abstract

This dissertation analyzes the legal classification of acute myocardial infarction (AMI) as an occupational accident, with particular emphasis on the causal nexus and the application of legal presumptions. Based on a technical-legal and jurisprudential approach, the study examines the challenges of recognizing AMI as a compensable work-related accident under Portuguese law, contrasting it with the normative and jurisprudential framework established in Spain, particularly under the Ley General de la Seguridad Social. The conclusion reached is that, while Portuguese jurisprudence has adopted a formalistic and restrictive stance—requiring evidence of abnormal and sudden exertion—Spanish jurisprudence reflects a more protective position, supported by a flexible presumption of work-relatedness. The dissertation ultimately advocates for an interpretative evolution within the Portuguese legal system, promoting a more effective application of occupational accident protection in AMI cases, whenever there are objective indications of a connection with professional activity.
