During admission for investigation of dysphagia, an 82-year-old woman suddenly complained of dyspnea, which was followed by cardiogenic shock. Her symptoms, electrocardiogram, echocardiogram and laboratory data were compatible with an extensive acute anterior myocardial infarction. Emergency cardiac catheterization showed no atheromatous narrowing in any coronary artery. However, the contractions of the left and right ventricles were diffusely and severely impaired, except for some hyperkinesis of the basal area. The asynergy, as well as the abnormalities on the ECG, improved almost to normal by the 35th hospital day. An endomyocardial biopsy from the right ventricle during the acute phase showed atypical myocardial damage with proliferation of fine collagen fibers and small round-cell infiltration including polymorphologic leukocytes. This type of transient cardiac disorder has recently been described in Japan, and is called 'Tako-tsubo cardiomyopathy' because of the characteristic appearance of the left ventricular asynergy. In the present case, ventricular asynergy was not limited to the left ventricle, but was also present in the right ventricle.

A 56-year-old woman with a 23 year-history of myotonic dystrophy was admitted to our hospital because of dysphagia and aspiration pneumonia. On admission, patient's ECG showed Ist degree of atrioventricular block and elongation of QRS (133 msec.). On the third hospital day, abnormal Q wave abruptly appeared in aVL associated with elevation of ST segment in V2 and V3, reverse T wave in I, II, III, aVF and V 2-6 leads on ECG. Echo cardiogram demonstrated asynergy at the apex and septal wall. Coronary angiography was normal. Left ventricular ejection fraction determined by left ventriculography decreased to 47.4%. Based on these findings, we thought "stunned myocardium" had developed. Biopsied myocardium from the apex, septum, and free wall showed non-specific findings including mild fibrosis and lymphocytic infiltration. Although overt myocardial disease is rare in myotonic dystrophy, myocardiac disease such as "stunned myocardium" not due to arrhythmia or coronary angiopathy may develop under severe infection, stress, and/or respiratory distress.
