Results
We analyzed left ventricular CMR parameters and outcome of 72 patients with a mean age of 68.8±17.5 years.
The majority were female patients (93%).
Initial CMR was performed in all patients 2 days after the index event (median: 2d; IQR 1-4).
CMR follow-up scan was conducted 2.3 months later (IQR 1.3-2.9) in 63 (88%) patients.
Anterior wall dysfunction was initially observed in 65 patients and resolved in 97%.
Median left ventricular ejection fraction significantly increased between both scans (49.5% vs.
60.0%,
P<0.001) and recovered in the majority of patients.
Myocardial edema significantly decreased in the follow-up scan (13.5% vs.
0.6%,
P<0.001).
Late gadolinium enhancement was not detected (Table 1).
We observed 9 (12%) MACE in the study population within a median of 24 months with the highest incidence of stroke (4.9%) and an estimated stroke rate of 2.9% after 30 days.
Left ventricular thrombus formation was found in one patient with acute stroke (Figure 1).
During index event one patient died (estimated mortality rate of 1.4% after 30 days).
Three patients died from non-cardiac events.
Two patients had a myocardial infarction or recurrence of TTS (estimated event rate of 1.5% after 30 days).
