91例病窦综合征患者,分别植入DDD(R)(n=56)及VVI(R)(n=35)起搏器,术后平均随访28.5±10.7个月。随访结束时与植入起搏器前比较,两组的左房内径均增大;左室射血分数降低;血浆BNP水平增高;Ⅰ级心功能患者减少;Ⅲ级心功能患者增加。而两组间以上各指标均无差异。DDD(R)组心房颤动发生率比VVI(R)组有降低趋势,但未达统计学差异(P=0.061)。两组间因心力衰竭住院率、脑梗塞及因心血管死亡均无差异。结论 :DDD(R)与VVI(R)起搏效果类似,均使患者心脏重构、心功能减退。
Ninety-one patients with sick sinus syndrome were implanted DDD (R) (n = 56) and VVI (R) (n = 35) pacemakers, respectively, with an average follow-up of 28.5 ± 10.7 months. At the end of follow-up, compared with before implantation of pacemaker, left atrium diameter increased, left ventricular ejection fraction decreased, plasma BNP level increased, grade Ⅰ cardiac function decreased and grade Ⅲ cardiac function increased. There was no difference between the above two groups of indicators. The incidence of atrial fibrillation in DDD (R) group was lower than that in VVI (R) group, but the difference was not statistically significant (P = 0.061). There were no differences in hospitalization rates for heart failure, cerebral infarction and cardiovascular death between the two groups. Conclusion: DDD (R) and VVI (R) pacing effect are similar, both patients with cardiac remodeling, cardiac dysfunction.
