Two-dimensional transthoracic echocardiography has been used to study patients during and after myocardial infarction. Quantitative studies have revealed that progressive increase in left ventricular size is associated with a poor prognosis. When pre-defined echocardiographic criteria were used to stratify infarction patients for adverse cardiovascular outcome, the efficacy of combined thrombolysis and angiotensin-converting enzyme inhibitor therapy could be shown in those who developed left ventricular enlargement. Other descriptors of left ventricular architecture and function, such as cavity shape and the ratio of short-axis left ventricular muscle to cavity area, may predict cardiovascular death and severe heart failure.
二维经胸超声心动图已被用于研究心肌梗死期间及之后的患者。定量研究表明，左心室大小的逐渐增加与预后不良相关。当使用预先定义的超声心动图标准对梗死患者进行分层以评估不良心血管结局时，在发生左心室扩大的患者中可显示联合溶栓和血管紧张素转换酶抑制剂治疗的疗效。左心室结构和功能的其他描述指标，如腔室形状以及短轴左心室心肌与腔室面积之比，可能预测心血管死亡和严重心力衰竭。
