Aim: The aim of our study was to determine the prevalence of the stress cardiomyopathy and to analyse clinical status, prognosis and

results of echocardiographic stress tests with dobutamine.

Methods: During six years (from January 2003 to December 2008) 2 143 patients with troponin positive ACS were examined in our cathlab

(Kardiologie na Bulovce). We confirmed stress cardiomyopathy in 11 patients (10 females). We have determined prevalence, clinical

profile, prognosis and performed with time-delay echocardiographic stress test with dobutamine.

Results: Total prevalence was 0.5 %. The mean age of the population was 63.5 ± 12.5 years. 30 % patiens had pulmonary oedema in the

acute phase of the disease and they were treated pharmacologically. Typical apical wall abnormality was observed in 8 of 11 patients

(72.7 %) compared to atypical (midventriclar) pattern in 3 of 11 patients (27.3 %). Mortality was 0 %, we did not detect relaps of the disease.

The stress test with dobutamine was perfomed at least 3 months after acute attack. We did not induce any global or local left ventricualr

motion abnormalities. We did not find the differences between groups with typicacal and atypical form of stress cardiomyopathy. We

did not record any severe side effect of dobutamine in the patiens.

Conlusions: The probable trigger of stress cardiomyopathy is more complex and with severe activation of catecholamines.
