对１２０例陈旧性心肌梗塞（ＯＭＩ）老年与老年前期患者，以心电图梗塞部位配对，进行对比分析。结果表明，老年人胸闷、下肢浮肿症状明显，ＰＥＰ／ＬＶＥＴ比值增高，心室扩大，室性早搏发生率高，室壁运动减弱明显。老年人ＯＭＩ伴高血压者，对心室扩大及室壁节段运动的影响较老年前期患者为重，提出老年人ＯＭＩ增龄后有无痛性增加、心室扩大、心力衰竭的特点。
120 elderly patients with obsolete myocardial infarction (OMI) and elderly patients were matched with electrocardiogram infarction sites for comparative analysis. The results showed that the symptoms of chest tightness and lower extremity in the elderly were obvious, the PEP / LVET ratio increased, the ventricular enlargement rate was higher, the incidence of ventricular premature beats was higher, and the wall motion was obviously weakened. Older OMI with hypertension, ventricular enlargement and wall segment segment exercise than pre-elderly patients as heavy, raised elderly OMI after a painless increase, ventricular enlargement, heart failure characteristics.
