BACKGROUND: Takotsubo syndrome (TTS) is a heart failure syndrome which is usually reversible. Factors associated with degree of recovery of left ventricular systolic function in TTS are poorly understood.
CONCLUSION: Takotsubo patients with partial myocardial recovery were older, presented with longer QT intervals, and were more likely to have comorbid hypothyroidism.

MATERIALS AND METHODS: We conducted a retrospective analysis of 90 TTS patients treated at our institution from 2006 to 2014. Patients were grouped based on recovery of left ventricular ejection fraction (LVEF) on follow-up transthoracic echocardiogram as left ventricular ejection fraction <50% (partial group) or preserved ejection fraction >=50% (full group). Patient baseline characteristics, comorbidities, biomarkers, electrocardiography, and echocardiogram were collected. We also compared adverse events that occurred during hospitalization.
RESULTS: In comparison to full recovery group patients (n=63), partial recovery patients (n=27) were older (76.9+/-13 vs. 70.6+/-13years; P=0.02) and had a higher prevalence of comorbid hypothyroidism (26% vs. 8%; P=0.02). A greater number of patients from the partial group were also taking levothyroxine replacement (22% vs. 3%; P=0.003). We found no significant between-group differences in type of triggering event or cardiac biomarker levels. QT interval was longer in the partial group (540.6+/-71msec vs. 460.7+/-35msec; P=0.01). Follow-up LVEF was 37.9+/-8% in the partial group and 58.0+/-4% in the full group (P<0.001). There were no statistically significant differences in length of stay or adverse events.
