In Reply: Dr Gnecchi-Ruscone raises the question of whether the previously reported predominance of Takotsubo cardiomyopathy in women is preserved in a setting of a large catastrophic event such as an earthquake. Among the 25 patients we described with Takotsubo cardiomyopathy following the Niigata-Chuetsu earthquakes in 2004, 24 (96%) were women. The mean age was 71.0 years (range, 49-83 years). Of the 2 patients with Takotsubo cardiomyopathy during the 20 control weeks, one was a woman and one was a man.

Onset of Takotsubo cardiomyopathy is usually preceded by acute personal events, such as a psychological or physical stress, and most of the patients are postmenopausal women (82%-100%; mean age, 62-75 years).^1-3 Given our findings, it appears that Takotsubo cardiomyopathy occurs more often in women regardless of the initial stressor.
