Abstract

BACKGROUND:

It is not clarified whether the transient, regional left ventricular dysfunction (TRLVD) associated with several neurological disorders shares the same pathophysiology with the classical tako-tsubo cardiomyopathy occurring without overt neurological disease, and whether it is appropriate to include these patients in a single stress cardiomyopathy (SCM) condition.

METHODS:

In February 2012, we systematically explored major electronic medical information sources to identify cases of TRLVD triggered by neurological disorders.

RESULTS:

The 81 selected papers reported a total of 124 patients, suffering from neurological disorders, in whom TRLVD occurred: 117 with central nervous system diseases, 6 with peripheral nervous system diseases and 1 with both systems involved. Most patients were females (n=102), mean age was 63 ± 15 years, and the majority presented with an apex-involving pattern. The most common disease described was subarachnoid hemorrhage (n=52), followed by stroke/transient ischemic attack (n=24), and seizures (n=18). TRLVD in neurological patients was often associated with need of inotropic support, orotracheal intubation, cerebrovascular spasm and delayed surgery.

CONCLUSIONS:

TRLVD is a complication of neurological diseases, in particular in female patients in post-menopausal phase. The predilection for neurological damage at or close to the insular cortex highlights the pivotal role of sympathetic over-activation. Many other similarities with tako-tsubo support the inclusion in a single SCM category.
