Síndrome de tako-tsubo, caracterización clínica y evolución a un año plazo

Background: Tako-tsubo Syndrome (TTS) is characterized by transient regional systolic dysfunction of the left ventricle (LV), mimicking myocardial infarction. It accounts for 0.9-1.2% of all acute coronary syndromes (ACS). Aim: To describe the incidence and characteristics of TTS within our popula...

It accounts for 0.9-1.2% of all acute coronary syndromes (ACS). Aim: To describe the incidence and characteristics of TTS within our population. Material and Methods: All patients diagnosed with ACS and TTS were selected from a clinical registry of all the coronary angiographies done in our hospital. Clinical features during initial presentation, hospital evolution and one year follow-up were analyzed. Results: The first case diagnosed in our hospital occurred in 2001. Since then, 4,433 coronary angiographies were done to patients with ACS until 2014 and 37 corresponded to TTS (0.83% incidence). The mean age of patients was 64 years, 73% were female, and 62% had hypertension. All patients had an identifiable trigger factor, abnormal EKG and elevated troponin. The coronary angiography did not show lesions in 97%. However, all had the characteristic extensive segmental-motility alteration with a mean ejection fraction of 44%. All patients were treated initially as an ACS. Seven patients had complications, namely acute cardiac failure in six and stroke in one. No patient died. At one year of follow-up, 100% showed normal segmental motility and ejection fraction, no patient had a new episode of TTS and all were alive. Conclusions: TTS is rare and the incidence found in this study is slightly lower than that reported elsewhere. TTS mimics ACS and it should be suspected by its clinical, electrocardiographic and enzymatic particularities. Coronary angiography helps to rule out other diagnosis. All patients normalize motility and ventricular function, which is the definitive differential feature respect to ACS.info:eu-repo/semantics/openAccessSociedad Médica de SantiagoRevista médica de Chile v.145 n.10 20172017-10-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0034-98872017001001268es10.4067/S0034-98872017001001268
