Takotsubo Syndrome: Clinical Features, Pathogenesis, Treatment, and Relationship with Cerebrovascular Diseases

Abstract

Purpose of Review

This review paper aims to provide a complete and updated overview on the clinical and pathophysiological aspects of Takotsubo syndrome (TTS), including prognosis, therapy, and the association with cerebrovascular conditions.

Recent Findings

TTS is an increasingly recognized non-ischemic cardiomyopathy characterized by sudden, temporary weakening of the myocardium, of which the pathogenesis is unknown.

Summary

Although pathogenesis of TTS remains unclear, a complex interaction between catecholamine-mediated stimulation, myocardial stunning, and subsequent stress-related myocardial dysfunction seems to be the main pathophysiological mechanism. Stroke is linked to TTS by a dual relationship since it may induce TTS by catecholamine release even if TTS itself also may be complicated by left ventricular thrombi leading to stroke. Given its possible complications, including the association with neurological diseases, both cardiologist and neurologists should be aware about TTS in order to diagnose it promptly and to initiate appropriate therapeutic measures.
