目的比较透析与非透析慢性肾功能衰竭患者并发急性心肌梗死的临床特征。方法按是否接受维持性肾透析分组,比较其临床特点。结果与非透析患者比较,透析患者入院诊断为急性心肌梗死的比例低,有胸痛患者比例少,肌钙蛋白阳性率高,心电图表现为ST段抬高者比例低,误诊率高;左室射血分数低,住院病死率高。结论维持透析的慢性肾功能不全并发急性心肌梗死临床表现不典型,容易误诊,预后不良,病死率较高。
Objective To compare the clinical features of acute myocardial infarction (AMI) patients with and without dialysis chronic renal failure. Methods According to whether or not to receive maintenance renal dialysis group, compare their clinical features. Results Compared with non-dialysis patients, dialysis patients admitted to hospital had a lower rate of diagnosis of acute myocardial infarction, fewer chest pain patients, higher positive troponin, lower electrocardiogram (ST-segment elevation) and higher misdiagnosis rate Low blood score, high in-hospital mortality. Conclusions The clinical manifestations of chronic renal insufficiency and acute myocardial infarction who maintain dialysis are not typical, easily misdiagnosed, poor prognosis and high mortality.
