摘 要:目的 探讨基线心率水平对人群全因死亡的影响.方法 选取参加2006-2007年度开滦集团健康体检有完整心电图资料且心率在40 ~ 120次/分、无心肌梗死和脑卒中病史93 716人为研究对象,研究随访期为2006年7月至2010年12月,平均随访时间(47.5±4.3)个月,随访期间每6个月收集一次全因死亡事件.结果 (1)总人群心率60 ~ 69次/分组累积死亡率最低为1.61%;男性心率60~ 69次/分组累积死亡率最低为1.78%;女性心率<50次/分组中没有发生全因死亡事件,80~89次/分组累积死亡率最低为0.60%.(2)Cox风险比例模型结果显示总人群心率70~ 79次/分组、80~ 89次/分组、90 ~ 99次/分组和≥100次/分组发生全因死亡的RR值(95%CI)分别为1.187(1.039 ~ 1.336)、1.392(1.185~1.636)、1.733(1.404 ~ 2.139)和2.716(2.171~3.398),男性人群各心率组发生全因死亡的RR值(95%CI)分别为1.227(1.067 ~ 1.410)、1.481 (1.254~1.750)、1.754(1.406 ~ 2.188)、2.831(2.245~ 3.571),女性人群以心率80~ 89次/分组作为对照组,心率60~ 69次/分组、70~79次/分组和≥100次/分组发生全因死亡的RR值(95%CI)分别为0.671(0.568~ 0.793)、0.825(0.703~ 0.970)、1.925(1.512 ~2.453).结论 心率≥70次/分后,随心率增加发生全因死亡事件率增加.心率与发生全因死亡的风险比呈J形曲线关系.Objective To investigate the relationship between baseline heart rate(HR) and all-cause death(ACD) in general population.Methods 93 716 workers with heart rate between 40 bpm/min-120 bpr/min and without histories of stroke were selected from the ‘2006-2007 health examination records' in Kailuan and completed the electrocardiogram exam.Related information were also gathered.These subjects were followed up from July 2006 to December 2010,with the mean time of follow-up as 47.5 ± 4.3 months.During the follow-up period,the occurrence of all-cause death was observed every half a year.Results (1) The lowest cumulative mortality rate was 1.61% in the group with 60-69 bpm/min.The lowest cumulative mortality rate was 1.78% in the group of 60-69 bpr/min in men.There was no death events observed in women with less than 50 bpm/min and the lowest cumulative mortality rate was 0.60% in the group of 80-89 bpm/min in women.(2)Data from Cox proportional hazard regression analysis showed that the RR(95%CI) of cumulative mortality rates in general population were 1.187 (1.039-1.336),1.392 (1.185-1.636),1.733 (1.404-2.139) and 2.716(2.171-3.398) in the groups of 70-79,80-89,90-99 and ≥100 bprn/min,respectively.The RRs (95% CI) of cumulative mortality in men were 1.227 (1.067-1.410),1.481 (1.254-1.750),1.754 (1.406-2.188) and 2.831 (2.245-3.571) respectively.In women,when comparing with the group of 80-89 bpm/min,the RRs (95% CI) of all-cause death were 0.671 (0.568-0.793),0.825 (0.703-0.970) and 1.925 (1.512-2.453) respectively in the groups of 60-69,70-79 and ≥ 100 bpm/min.Conclusion When HR exceeding ≥70 bpm/min,the increase of HR would also increase the rate of ACD.Results of our study also showed a J-shaped curve relation between HR and mortality.
