May attenuate stress-induced LV dysfunction in estrogen-deficient rats; hypothesis-generating for estradiol in postmenopausal Takotsubo cardiomyopathy.
Does estradiol supplementation prevent emotional stress-induced cardiac responses in an ovariectomized rat model of Tako-tsubo cardiomyopathy?
Estradiol supplementation attenuates stress-induced reductions in left ventricular contraction and excessive heart rate increases in a rat model of Tako-tsubo cardiomyopathy, providing a potential mechanistic explanation for the condition's prevalence in postmenopausal women.
