Background Tako-Tsubo syndrome (TTS) is a form of acute heart failure which mostly affects postmenopausal women, often following an emotional or physical trigger factor. There are many hypotheses for the development of TTS but the complete pathophysiology still remains unclear. Although most patients recover after a few days, some have to be treated at the intensive care unit (ICU) and may even die from the condition. Purpose The aim of this study was to find out if pre-existing diseases,
... vascular risk factors (CVRF), comorbidities and trigger factors have any impact on the short-term outcome of TTS patients. Methods Data of all patients who presented to our centre with TTS from 2009–2017 were gathered retrospectively. Baseline characteristics, including somatic and psychiatric pre-existing diseases, CVRF (smoking, hypertension, diabetes, dyslipidaemia) as well as physical and emotional trigger factors were collected. Somatic diseases were additionally categorised into cardiac, autoimmune, malignant and other diseases. Admission to intensive care unit post TTS and/or in-hospital death were defined as poor short-term outcome. Outcome predictors were analysed with binary logistic regression model using the combined variable admission to an ICU and/or death. Results Out of 102 patients, 84 (82.4%) were females and 18 (17.6%) males with a median age of 65±15 years. 30 (29.4%) patients had an emotional and 23 (22.5%) a physical trigger factor. 27 (26.5%) had a psychiatric and 88 (86.3%) a somatic pre-existing disease. 33 (32.4%) patients were smokers, 58 (56.3%) had hypertension and 18 (17.5%) were diabetics. 19 patients (18.6%) had to be admitted to ICU and 8 patients (7.8%) died. No pre-existing diseases, baseline characteristics, CVRF or comorbidities behaved as significant independent predictor for bad outcome in TTS patients. Physical trigger was the only significant predictor for ICU admission and/or death (p=0.012). Conclusion Our study showed that patients with physical trigger factors have a higher risk of ICU admission and/or death than patients with emotional or no stressful trigger factors before TTS and should therefore be monitored closely. Interestingly, contrary to many other acute cardiac diseases, pre-existing diseases, cardiovascular risk factors and comorbidities do not seem to have any impact on the short-term outcome of patients with TTS.
