And we continue our session with stress cardiomyopathy:
Diagnosis of Stress cardiomyopathy:
Usually, patients present with acute heart failure although the condition may also be asymptomatic.
The ECG typically shows signs of acute or anterior myocardial infarction.
Echocardiography reveals systolic and diastolic dysfunction almost indistinguishable from acute MI due to LAD occlusion.
Troponin elevation (0.01–5.3 ng/mL) is the rule.
In a review of 240 patients diagnosed with takotsubo cardiomyopathy, 211 were found to have completely normal coronary arteries, whereas the remainder had noncritical stenoses.
