What is the incidence, angiographic profile, and clinical outcome of apical ballooning syndrome compared to STEMI in the HORIZONS-AMI trial?
Apical ballooning syndrome is a rare presentation in the setting of primary PCI for AMI, occurring exclusively in women in this cohort, and is associated with less severe coronary disease and a favorable short-term prognosis regarding MACE.
In HORIZONS-AMI, ABS was identified exclusively in women (2.1% of female patients, 0.5% of all patients) and MACE were absent in this uncommon but important group of patients. Coronary artery disease was often present in patients with ABS, but its prevalence and severity was significantly less compared with STEMI patients.
