“…The most widely accepted diagnostic criteria are those of the Mayo Clinic [5], which requires normality of the epicardial coronary arteries (Table 2). Other proposed diagnostic criteria admit non-significant coronary artery lesions [6] (Table 3) and, in the absence of coronary angiography, accept the results of echocardiography, cardiac magnetic resonance imaging, or isotope ventriculography [7] (Table 4). Kawai et al [8] define this syndrome as a nosological entity in which there is acute ballooning of the apex of the left ventricle (LV) of unknown aetiology (Table 5).…”

“…The most common symptom is precordial pain [6,7,34,69], although this may be atypical; it is reported in 50–100% of cases at onset [3,5,15,22–26,33–36,48,50,51,64–66,68,69] and is more common in whites [66]. African-Americans more commonly present with respiratory insufficiency [31].…”

“…Although the initial electrocardiogram (ECG) may be non-specific or normal, the majority (11–100%) present elevation of the ST segment, particularly affecting the anterior wall (36–100%) and, more rarely, the inferior or lateral walls (4–50% and 5–70%, respectively) or in aVR [3,6,7,13,15,21–26,33–36,50,54,64–66,70,96–99]; ST segment depression has been reported in 6–23% [13,64]. These changes may be very dynamic [98,99].…”

“…An absence of R-wave progression in the anterior wall may also be seen (7–32%) [17,22]. T wave inversion is very common (17–100%) [7,13,15,21,33–36,64,66,96–98], and may be associated with a poorer prognosis [62,98]; however, peaked T waves sometimes predominate (86%) [64,98]. A long QTc interval is seen in 50–100% [3,7,12,21–26,64].…”

SummaryStress cardiomyopathy is characterised by reversible left ventricular dysfunction. It simulates an acute coronary syndrome (ACS), presenting with precordial pain or dyspnoea, changes of the ST segment, T wave, or QTc interval on electrocardiogram, and raised cardiac enzymes. Typical findings are disturbances of segmental contractility (apical hypokinesia or akinesia), with normal epicardial coronary arteries. The true prevalence is unknown, as the syndrome may be under-diagnosed; it is more common in postmenopausal women. There is usually a trigger in the form of physical or psychological stress. The electrocardiographic, echocardiographic, and ventriculographic changes resolve spontaneously over a variable period of time (from days to months). There are a number of pathophysiological theories, none of which has been shown to be definitive, suggesting that all of them may be involved to some extent. The prognosis is generally favourable, and recurrence is very rare.
