“…16) Recently, Ogura, et al compared ECG findings between Tako-Tsubo cardiomyopathy and AMI, and reported that the longer QTc interval and the absence of abnormal Q waves in the anterior leads and reciprocal changes in the inferior leads could help to distinguish Tako-Tsubo cardiomyopathy from AMI. 17) Although a definite diagnosis by coronary angiography was lacking in this case, considering similar ECG findings, easy reversibility of cardiac function, and the pre-existing stressful condition of exposure to high ambient temperature, the cardiac abnormality probably resembled the state of Tako-Tsubo cardiomyopathy. The prominent impaired wall motion in the apex region observed when he was transferred to the emergency room may reflect the typical abnormalities seen in Tako-Tsubo cardiomyopathy.…”

A Case of Severe Heat Stroke With Abnormal Cardiac Findings

SUMMARYWe document serial changes in the electrocardiogram (ECG) and myocardial markers in a case of severe heat stroke treated with cooling procedures. A 23-year-old comatose male with heat stroke was presented in the emergency room. The condition of the patient was complicated by hepatic failure, rhabdomyolysis, acute renal failure, and cardiac abnormalities. ECG revealed diffuse ST-T elevation; serum levels of myocardial markers were remarkably high and diffuse hypokinesis was observed on the echocardiogram. Cooling procedures, including applying cold vapor to the patient's skin, a gastric lavage with cold water, and an intravenous cold fluid infusion were not successful. Since multiple organ damage (heart, liver, central nervous system, and kidney) was evident, we utilized continuous hemodialysis and hemofiltration, using cold dialysate for efficient cooling. The patient recovered from the multiple organ damage and was removed from the intensive care unit 14 days after the onset. The cardiac abnormalities had normalized within several days without any damage to the myocardium. Q waves were not detected in any lead in the ECG. When interpreting ST-T elevation in the ECG of a heat stroke patient, caution should be used so as to not misdiagnose it as an acute myocardial infarction. (Int Heart J 2005; 46: 543-550) Key words: Heat stroke, Electrocardiography, Multiple organ failure, Myocardium HEAT stroke is an acute thermoregulatory failure that often results from exposure to high temperatures.1) The diagnosis of heat stroke is usually based on central nervous system dysfunction and a rectal temperature of 41°C or higher, as well as occasional multi-organ damage and dysfunction.2,3) Heat stroke can be exercise induced (exertional) or non-exercise induced (classic), and occurs when heat gain exceeds heat loss from the skin by radiation, convection, or evaporation. 4)Several cardiac complications have been documented in heat stroke cases, 5,6) and certain nonspecific ECG changes, including ST-T elevation, have been described. ST-T elevation is rare in heat stroke and is sometimes attributed to corFrom the

Takotsubo cardiomyopathy (TC) is a transient, reversible form of cardiomyopathy which predominantly affects post-menopausal women and is an important differential diagnosis of acute coronary syndrome. It is characterised by normal (or near-normal) coronary arteries, regional wall motion abnormalities that extend beyond a single coronary vascular bed, and often proceeded by a stressful event. The pathophysiologic mechanism is complex and remains to be elucidated. There is increasing awareness among physicians about TC and hence, more cases are being reported. The diagnosis of TC has important clinical implications in the management at presentation and afterward. In this review, we discuss the demographics, clinical features, prognosis and management of this cardiomyopathy.
