Chronic pharmacological treatment in takotsubo cardiomyopathy

Background: Takotsubo cardiomyopathy is a disorder that has been appreciated only recently. In most of reported cases, this syndrome mimes an acute myocardial infarction. Till this moment no data are available from literature about the treatment in the acute phase of this disease. Aim of the study: In our multicentric experience we have retrospectively looked at the benefits of a treatment with ACE-inhibitors, beta-blockers, Aspirin and calcium channels blockers, started until the early phases of the disease and continued for 30 days, in 36 patients affected by Takotsubo cardiomyopathy. We chose as endpoint of the study the efficacy of the used drug in improving left ventricular myocardial function and the rapidity of the effects of the same drug.bethods: from an international registry about the Takotsubo cardiomiopathy, co-ordinate by our research group, we evaluated the long term efficacy of some drugs, administrated like single treatment in some patients. Results: Obtained data did not show any statistically significant difference in the percentages of improvement in the left ventricle ejection fraction evaluated at the admission to the hospital, before the discharge and after 30 days of treatment between each treated group and the control group of non-treated patients. No significant differences were found in hospitalization times between treated patients and controls. None of our patients experienced during the observation period a relapse of the disease. Conclusions: The results of our survey suggest that a chronic treatment with beta-blockers, ACE-inhibitors, calcium channels blockers and aspirin does not provide any benefit in patients with Takotsubo cardiomyopathy. Thus, it seem to be important an early correct differential diagnosis to avoid any chronic treatment in these patients. (C) 2007 Elsevier Ireland Ltd. All rights reserved.
