Observations of the relationship between left ventricular aneurysm and ST segment elevation in patients with a first acute anterior Q wave myocardial infarction

摘要: Seventy-eight consecutive survivors of a first acute anterior Q wave myocardial infarction (AMI) underwent two-dimensional echocardiography (2D echo), colour Doppler echo and radionuclide angiography (RNA) for the diagnosis left ventricular (LV) anteroapical aneurysm, in order to study relationship this complication precordial ST segment elevation these patients. The (mm) lead V2, maximum V 1-V6 sum V1 V6 were calculated. LV aneurysm was present 19 patients by 2D echo, whom 12 had paradoxical systolic flow pattern (red outward towards transducer) at apex. There no difference between mean V2 or V1-V6 with without an although elevations higher former group (P<0.01). also did not differ significantly. Wall motion abnormality (akinesis dyskinesis) wall seen 74% 36% (P<0.005), septal region 63% 47% respective (P-NS). There magnitude subgroups ejection fraction (EF) ≤30% ≥40%, but EF (23 ± 2.1%) (34 1.3%) differed (P<0.001). It is concluded that does clearly aneurysm. It related akinesis dyskinesis regions inherent AMI indicate impaired function.
