JAMA Intern Med:胸痛低心梗风险者或无须进一步接受任何无创检查

2015-02-03 杜卉编译 中国医学论坛报

美国学者研究发现,因胸痛就诊于急诊并经评估未发现有心梗者,则在随后的短期和长期的随访中发生心梗的风险极低。论文1月26日在线发表于《美国医学会杂志·内科学》(JAMA Intern Med)。 研究者经回顾性分析2011年全年的全国健康保险理赔数据库资料,纳入因原发或继发性胸痛就诊于急诊者,并根据其所接受的检查方法分为以下几类:未接受无创检查、运动心电图检查、超声心动图检查、心

美国学者研究发现,因胸痛就诊于急诊并经评估未发现有心梗者,则在随后的短期和长期的随访中发生心梗的风险极低。论文1月26日在线发表于《美国医学会杂志·内科学》(JAMA Intern Med)。

研究者经回顾性分析2011年全年的全国健康保险理赔数据库资料,纳入因原发或继发性胸痛就诊于急诊者,并根据其所接受的检查方法分为以下几类:未接受无创检查、运动心电图检查、超声心动图检查、心肌灌注显像检查或冠状动脉CT血管造影检查,以对这些胸痛评估方法进行比较。

结果为,2011年,共有693212例次因原发或继发性胸痛所致急诊就诊,占全部急诊就诊数量的9.2%。经入组和排除标准筛查,最终有421774例患者被纳入最终的分析,其中293788例未接受初次无创检查,127986例接受了检查。

接受分析的患者,在7天和190天的随访中,因心梗而住院的比例极低,分别为0.11%和0.33%。未接受初次无创检查者发生心梗的可能性不高于接受无创检查的患者。

与未接受无创检查相比,运动心电图检查、心肌灌注显像检查和冠状动脉CT血管造影检查与较高的须接受心导管检查和血管重建术的风险相关,同时,不改善发生心梗的风险。

 据2月22/29日刊《美国医学会杂志》上的一项研究披露,在心肌梗死的患者中,女性比男性更有可能在医院中表现为没有胸痛,且在相同的年龄组中,她们还有比男性更高的住院死亡率,尽管这些差别会随着年龄的增长而减少。   佛罗里达莱克兰市沃森诊所及莱克兰地区医疗中心的John G. Canto, M.D., M.S.P.H.及其同事对考虑了因MI而住院的患者年龄前
