BACKGROUND: Takotsubo cardiomyopathy (TTC) is an acute and usually reversible condition that often mimics the course of acute coronary syndrome (ACS), making it particularly challenging to differentiate, especially in the initial phases. In this study, we retrospectively analyzed the incidence, clinical course, examination results, and in-hospital mortality of TTC in patients with ACS hospitalized at our cardiology center from January 2018 to October 2023.
RESULTS: During the study period, a total of 3835 selective coronary angiograms were urgently performed at our facility, with a diagnosis of TTC established in 52 (1.35%) patients, the majority of whom were females-48 (93%), with an average age of 64.2 ± 10.2 years. Stress-induced mechanisms were identified in 36 (69%) patients. The most common symptom was chest pain (86.5%). Electrocardiographic changes primarily included ST-segment elevations (61.6%) and depressions (14%). The average left ventricular ejection fraction was 45.1 ± 8.3 (33-57%), typically with an echocardiographic pattern of apical ballooning dysfunction followed by midventricular dyskinesia. In-hospital mortality was zero.
CONCLUSIONS: TTC is a reversible condition with a low incidence of complications. Its occurrence in our patient cohort is lower compared to international registries. However, as demonstrated in this study, it is associated with significant in-hospital morbidity.
