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