Clinical and echocardiographic characteristics of patients with acute myocardial infarction according to the presence or absence of left ventricular thrombosis at any time
| LVT absent (n=693) | LVT present (n=64) | p Value | |
|---|---|---|---|
| Values are mean (SD) or %. | |||
| AMI, acute myocardial infarction; CABG, coronary artery bypass graft; EDVI, end diastolic volume indexed; EF, ejection fraction; ESVI, end systolic volume indexed; LV, left ventricular; LVT, left ventricular thrombus formation; MR, mitral regurgitation (the numbers 2–3 indicate the severity of the regurgitation); PTCA, percutaneous transluminal coronary angioplasty; WMA, wall motion asynergy. | |||
