Takotsubo cardiomyopathy (TTS) is a peculiar clinical condition often affecting postmenopausal women after a stressful trigger. The underlying mechanisms have not been completely elucidated but several hypotheses have been advanced, with catecholamine cardiotoxicity, microvascular dysfunction and coronary artery spasm each suggested to play a role. The incidence of stroke after TTS appears to range from 0% to 7.7%, and interestingly TTS has been described as both a cause and a complication of stroke. We sought to assess the incidence and predictors of stroke during the index event (peri-index event stroke) in a heterogeneous TTS population. We conducted a retrospective descriptive study reviewing patients who were discharged with a diagnosis of TTS from the Einstein Medical Center, Philadelphia, PA and Danbury Hospital, Danbury, CT in the period between 2003 and 2014. A total of Incidence and predictors of stroke during the index event in an ethnically diverse Takotsubo cardiomyopathy population 206 patients met the modified Mayo Clinic criteria and were included in the study. The patients' overall mean age was 67.8 years; 87% (n=179) were females and 25% (n=53) were African Americans. The following incidence rates were found: stroke 7%, in-hospital heart failure 26.7%, and in-hospital death 7%. On multivariate analysis independent predictors (expressed as odds ratios with 95% confidence intervals) of periindex event stroke were: i) African American race (OR 3.2, 95% CI 1.2-10.2, p=0.048); ii) hypertension (OR 10.5, 95% CI 1.3-88, p=0.03). ACE inhibitor use was a protective factor for developing peri-index event stroke (OR 0.15, 95% CI 0.04-0.5, p=0.001). There was a trend towards dual antiplatelet therapy (DAPT) being protective for stroke (OR 0.3, 95% CI 0.05-1.1, p=0.08). The incidence of peri-index event stroke was 7%. African American race and hypertension were found to be independent predictors of peri-index event stroke. Prospective clinical trials are needed to confirm these findings and to better determine the impact of hypertension as a risk factor for stroke and to assess the role of DAPT in preventing it.
