Objective Among patients with acute cardiac syndromes without coronary stenosis, the clinical, electrocardiographic, echocardiographic, and angiographic features of those a first myocardial infarction (AMI) were compared apical-ballooning syndrome (ABS). Methods Data consecutive admitted AMI (n=30) or ABS (n=45) reviewed. Results Patients older (72 vs. 56 years; P=0.001) presented higher frequency female sex (91 43%; P=0.001), triggering emotional physical stress (47 17%; P=0.003) lower rate tobacco smoking (27 50%; P=0.051) than AMI. They also greater number leads (5.5 3.6; P=0.01) more anterior anterior+inferior involvement (96 40%; P<0.001), depressed ejection fraction (45 57%; proportion akinesia diskinesia (89 27%; that extended beyond boundaries single-vessel territory, left ventricular outflow obstruction (29 0%; heart failure (38 10%; P=0.015). Frequency nonsignificant stenosis smooth vessels, however, was similar in both groups. Conclusion frequently women significant had larger hypocontractile areas. The preponderance smoking, pain triggers, hypocontractility limited to one-vessel territory latter, may suggest transient thrombotic/vasospastic event as their underlying mechanism opposed ABS.
