Abstract:
Strain imaging is a sensitive marker of myocardial dysfunction and may be underused in Takotsubo cardiomyopathy (TC). We present a case of biventricular TC in which early improvement in left ventricular longitudinal strain predated subsequent improvement in ejection fraction. Early temporal patterns of strain of the left and right ventricles have not previously been described in TC. Our case illustrates how strain can be a sensitive marker for myocardial dysfunction and recovery in TC. Increased use of strain in TC may have further implications on prognosis and management.

The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
