Background and Objectives: Takotsubo syndrome (TTS) is a form of reversible cardiomyopa-thy often preceded by mental or physical stressors and predominantly affects elderly women. Several cardiac and inflammatory biomarkers are involved in the pathogenesis of the disease. We aimed to investigate the correlation of C-reactive protein (CRP) level with left ventricular ejection fraction (LVEF) and clinical outcomes in patients with TTS. Methods: The study included patients with discharge-diagnosis of Takotsubo through 2017– 2022 from the cardiology department. Demographic, laboratory, echocardiographic, and clinical outcomes were retrospectively obtained. We investigated the relation between CRP and LVEF, length of stay (LOS), in-hospital complications, and recurrence. Results: A total of 86 patients (93% female, mean age 68.8±12.3 years) were included in the study. The median CRP level was 17.4 (interquartile range [IQR], 6.1–40.1) mg/L, and the mean LVEF was 41.5%, (IQR, 38–50%). Complications occurred in 24 (27.9%) of the patients, and the median LOS was 3 (IQR, 3–5) days. The level of CRP was associated with lower LVEF (r=−0.39, p<0.001), longer hospital stay (r=0.25, p=0.021), and recurrence. There was no correlation between CRP and in-hospital complications. In multivariate logistic regression, poor LVEF was associated with TTS recurrence (odds ratio, 1.22; 95% confidence interval, 1.08–1.37; p=0.001). Using linear regression, only CRP was correlated with longer LOS and lower LVEF (p<0.001). Conclusions: Among patients hospitalized with TTS, CRP level was associated with poor LVEF and prolonged hospital stay but not with in-hospital complications. Poor LVEF was also associated with TTS recurrence.
