为评价扩张型心肌病患者一年内发生猝死的预测因子,作者对33例扩张型心肌病患者进行了前瞻性研究.每例患者均有详细的病史、体检、两维超声心动图记录,并行24小时动态心电图监护.31例作心导管检查与冠脉造影,26例作左心室造影术,有2例还作了尸体解剖.随访期为一年.经单变量分析显示,预测扩张型心肌病患者一年内有猝死危险性的重要因子是:24小时动态心电图测得的每小时最多室性早搏次数(PVCs/h),p=0.0012;每阵非持续性室性心动过速发作时心搏次数的最大值(VT_(max),p=0.0012;以及左室舒张末期压,p=0.046.
To assess the one-year risk of sudden death in patients with dilated cardiomyopathy, we conducted a prospective study of 33 patients with dilated cardiomyopathy, each with a detailed history, physical examination, two-dimensional echocardiographic recording, and 24 Hour dynamic electrocardiogram monitoring .31 cases of cardiac catheterization and coronary angiography, 26 cases of left ventricular angiography, 2 cases were also autopsy .A follow-up period of one year.Univariate analysis showed that the prediction of dilated cardiomyopathy Important risk factors for sudden patient death within one year were: maximum number of premature ventricular premature beats per hour (PVCs / h) measured on a 24-hour Holter, p = 0.0012; heart rate at each episode of episodic non-sustained ventricular tachycardia The maximum number of times (VT max, p = 0.0012; and left ventricular end diastolic pressure, p = 0.046.
