为探讨一些常见的临床参数中影响慢性充血性心衰(CHF)的决定因素,我们对21名特发性扩张性心肌病及缺血性心肌病患者进行为期28个月的追踪研究。使用Cox相对危险标准对15个临床变量进行分析,同时也统计了一些个别变量作为独立的预后指标。研究表明,有三个特征可独立预测死亡率增高的危险:即左室射血分数(LVEF)、最大摄氧量(Vo_2max)和缺血性心肌病。因此提示对伴有与缺血性心肌病有关的左室功能障碍、运动耐力降低、进行性的 To investigate the determinants of some common clinical parameters affecting chronic congestive heart failure (CHF), we conducted a 28-month follow-up study of 21 patients with idiopathic dilated cardiomyopathy and ischemic cardiomyopathy. Fifteen clinical variables were analyzed using the Cox relative risk criteria, and some individual variables were also counted as independent prognostic indicators. Studies have shown that there are three characteristics that independently predict the risk of increased mortality: left ventricular ejection fraction (LVEF), maximal oxygen uptake (Vo_2max), and ischemic cardiomyopathy. Therefore, prompted with left ventricular dysfunction associated with ischemic cardiomyopathy, decreased exercise tolerance, progressive
