ABSTRACT: Hyperhidrosis is a condition resulting from a systemic sympathetic hyperactivity. The gold standard treatment is the resection or surgical ablation of the paravertebral sympathetic chain: the endoscopic thoracoscopic sympathectomy (ETS). Non-cardiac thoracic surgeries carry a considerable incidence of pathological postoperative cardiac events, raising attention to possible worsen cardiac functional capacity after the resection of a pair of thoracic sympathetic ganglia. The aim of this study is to investigate literature evidences of postoperative cardiovascular functional changes on patients submitted to ETS as treatment for hyperidrosis. This is a systematic review of the literature. Clinical studies published between January 1999 and April 2019 were analyzed. The PICO strategy was used to construct the question of systematic reviews research. The process of selecting articles was organized according to PRISMA Diagram. The search in electronic databases resulted in seven articles, of which one was excluded for being out of scope of the research, leaving six articles. All studies showed a pattern of heart rate (HR) reduction after endoscopic thoracic sympathectomy. It was suggested a relation between the extension of the procedure and the presence of cardiac functional alterations. There was an improvement in myocardial physical conditioning and maintenance of functional capacity. To elucidate the real mechanisms involved in the maintenance of myocardial function, and even its improvement, it is necessary to develop further studies that directly evaluate them.
