摘要
目的了解中度收缩性心力衰竭伴发非持续性室性心动过速（NSVT）患者的临床相关因素。方法将119例左室射血分数（LVEF）在0.30-0.50之间的心衰患者分为NSVT组（n=50）和无NSVT组（n=69）,统计年龄、性别、基础疾病、血压、药物使用情况、心脏超声指标、临床生化指标、心电图特征,采用Logistic回归分析评价NSVT与上述临床指标的相关性。结果与无NSVT组比较,NSVT组患糖尿病者比例高,左室舒张末期内大、LVEF低,肌钙蛋白I（TnI）、B型脑钠肽（BNP）及糖化血红蛋白（糖化HGB）高,QRS波时限长（P均〈0.05）。单因素及多因素Logistic回归分析均提示TnI、糖化HGB及QRS波时限与NSVT发生呈独立正相关。结论对于中度收缩性心力衰竭伴发NSVT的患者,NSVT的发生与心功能状态、糖化HGB及QRS波时限相关。
Objective To study the relative and clinical factors of moderate systolic heart failure patients complicated with nonsustained ventricular tachycardia（ NSVT）. Methods One hundred and nineteen patients with left ventricular ejection fraction（ LVEF） between 0. 30 and 0. 50 were divided into two groups according to having NSVT or not. There were 50 cases in NSVT group and 69 cases in non-NSVT group. Age,gender,underlying diseases,blood pressure,drug use, echocardiography results,biochemical indexes,electrocardiography feature were counted. The Logistic regression analysis were used to evaluate the relations between NSVT and these clinical factors. Results Compared with non-NSVT group, patients in NSVT group had higher ratios of diabetes mellitus,larger left ventricular end diastolic diameter,lower LVEF, higher TnI,BNP and HAb1c concentration,and longer QRS duration. According to single and multiple regression,a positive correlation was shown between TnI,HAblc,QRS duration and NSVT（all P 0. 05）. Conclusion For moderate heart failure with NSVT patients,NSVT are correlated with immediate cardiac function,HAb1c and QRS duration.
