In patients diagnosed with fixed defects (infarctions), 86% of men and 71% of women had abnormal gated studies (hypokinesis or akinesis wall motion).
Echocardiography estimated LV ejection fraction (LVEF) at 24% and confirmed akinesis of the mid and apical left ventricle with preservation of the basal function.
sup][13],[14] Moreover, when the RWMA develops into akinesis or dyskinesis, a circulation disorder will act to increase the incidence of LVT, which was also indicated by this study.
In our patient, TCM was diagnosed since new ECG abnormalities (ST-segment elevation) and modest elevation in serum markers suggestive of cardiac damage in accordance with transient akinesis of LV mid segments with apical involvement in the absence of obstructive coronary disease or angiographic evidence of acute plaque rupture were present after exposure to an emotional stressor.
The Mayo criteria (all must be met) for diagnosis of this syndrome include the presence of transient left ventricle apical akinesis or dyskinesis, absence of obstructive coronary disease, new electrocardiographic abnormalities and absence of concurrent conditions such as head trauma, intracranial bleeding, phaeochromocytoma, myocarditis and hypertrophic cardiomyopathy (15).
A cardiac catheterization revealed a complete occlusion of the right coronary artery and mild distal left anterior descending artery stenosis, as well as inferior ventricular wall akinesis.
Akinesis of the apical chamber is attributed to ischemia from increased wall stress and work due to high systolic and diastolic pressures combined with massive hypertrophy.
Abnormalities of left ventricular wall motion (hypokinesis, akinesis, and/or dyskinesis) were documented by ECHO in 97 (80.
A transthoracic echocardiogram showed a mildly dilated LV, moderate to severe segmental systolic dysfunction, with inferior wall akinesis and hypokinesis of the septum, apex and distal anterior wall.
The echo showed segmental wall motion abnormalities consisting of apical akinesis, mild anterior and anteroseptal hypokinesis, and ejection fraction of 45 to 50%.
Akinesis of the mid to distal anterior wall of the left ventricle was also noted.
ECHO findings were positive for focal anterior and lateral segmental akinesis with an LVEF of 40% to 44%.
