20 @entity1 with @entity583 and a medical history of less than six hours were treated with immediate percutaneous transluminal coronary angioplasty. The median time from start of symptoms until establishment of reperfusion of the @entity1188 related artery was 190 minutes, and the time from admission to insertion of the balloon was 52 minutes. Angioplasty was successful in all @entity1 , with no serious complications. All @entity1 experienced @entity158 relief immediately after angioplasty. No @entity1 died or had further @entity1188 . None needed hospitalization during the first three months of follow up. Eight @entity1 had an exercise test between five and seven days after angioplasty and the other 12 at their six-week check up; there were no signs of @entity63 or @entity158 . Measurement of global ejection fraction one week and six weeks after treatment showed median normal values and no significant changes (58% versus 57%). Myocardial perfusion imaging was carried out in eight @entity1 both before hospital discharge and six weeks later. Normalization and improvement was seen in six @entity1 using this method, whereas the perfusion was found unaltered in two @entity1 . Hibernation or stunning, or both are suggested as possible explanations for this. We found the method highly effective and safe in selected @entity1 .
