| Popis: | Objectives: A newly discovered heart syndrome mimicking acute coronary syndrome has been termed ‘Tako-Tsubo cardiomyopathy’ (TTC). Differentiation from acute myocardial infarction using the ECG is an important issue in clinical practice. Methods: We retrospectively analyzed patients admitted for cardiac catheterization between September 2003 and September 2006. Results: From 26,593 cardiac catheterization procedures, we identified 21 patients with suggested TTC (0.08%). Trigger mechanisms were present in 38.1%; all patients had elevated troponin levels (mean 3.9 ng/ml). Median age was 68.4 years; 90.5% were female. Hypertension was seen in 85.7% and atrial fibrillation in 19.1%. Specific ECG findings related to a TTC are: a mild elevation of the ST segment arising from the S curve of the QRS complex, where the maximum ST segment elevation at the basis of the T wave is Follow-Up Data: Mean follow-up was 13.2 months. 47.6% were free from angina or dyspnea, most of the patients received β-blockers/ACE inhibitors (76.2%). One patient had a sudden cardiac death (4.8%), 1 patient became an implantable cardioverter-defibrillator primarily due to resuscitation. Conclusion: TTC is a rare syndrome mimicking acute coronary syndrome that shows a specific ECG pattern and does not appear to be an unambiguously benign disease. |
