Abstract/OtherAbstract:
We assessed the clinical characteristics and determinants of the prognosis of patients with left ventricular ballooning syndrome (LVBS) in an European population. A total of 128 patients with LVBS (98% women, age 67 ± 11 years) were prospectively followed up for a median of 13 months. A trigger event was identifiable in 58% of the patients. Anterior ST-segment elevation was documented in 38% and negative T waves in 41% of the patients. Apical ballooning was present in 82% and midventricular ballooning in 18%. The initial LV ejection fraction was 41 ± 9%. In-hospital events included the death of 1 patient (0.8%), LV failure in 13 (10%), LV thrombi in 4 (3.1%), sustained ventricular or supraventricular tachyarrhythmias in 6 (4.7%) and asystole in 2 patients (1.6%). The extent of wall motion abnormalities (odds ratio 4.16, p = 0.012), dyspnea at presentation (odds ratio 3.42, p = 0.01), and treatment with nitrates (odds ratio 0.30, p = 0.015) were significant univariate predictors of in-hospital events. The recovery of regional wall motion abnormalities occurred within 1 month of the event in 73% of patients. During follow-up, events occurred in 7 (6%) of 121 patients, including noncardiac death in 1 (0.8%), recurrent LVBS in 2 (1.6%), heart failure in 1 (0.8%), and recurrent chest pain in 3 (2.5%). In conclusion, in a European population, LVBS was characterized by a significant rate of in-hospital events, mainly related to pump failure, and low short-term mortality. The extent of wall motion abnormalities was the best predictor of acute events. Contractile recovery occurred within 1 month in most patients. The long-term prognosis was good, with a recurrence rate of <2%/year.
