Circulation:心血管疾病患者的癌症风险较高?未必!

2018-08-20 国际循环编辑部 国际循环

在社区观察性研究中,有证据显示,心血管疾病与较高的癌症发病率有关。2013年,Hasin等人的研究表明,心力衰竭和后续确诊癌症存在联系。这些发现在对心肌梗死人群的前瞻性队列研究中得到重现,丹麦的大规模心力衰竭队列研究中也观察到类似结果。然而,值得注意的是,这些流行病学研究并未区分射血分数保留型心力衰竭与射血分数降低型心力衰竭对这种相关性的影响差异。

非传染性疾病每年导致超过4000万人死亡,占全球死亡人数的70%。目前,每年有17.7万人死于血管疾病,而癌症每年造成880万人死亡。在社区观察性研究中,有证据显示,血管疾病与较高的癌症发病率有关。2013年,Hasin等人的研究表明,心力衰竭和后续确诊癌症存在联系。这些发现在对心肌梗死人群的前瞻性队列研究中得到重现,丹麦的大规模心力衰竭队列研究中也观察到类似结果。然而,值得注意的是,这些流行病学研究并未区分射血分数保留型心力衰竭与射血分数降低型心力衰竭对这种相关性的影响差异。

共同的风险因素和生物机制也许可以解释这种关系。事实上,心血管疾病的风险因素,如不健康的饮食、吸烟、肥胖、糖尿病高血压等,都与癌症风险的增加有关。此外,某些心血管药物(β受体阻滞剂等)、诊断评估、表观遗传机制和再生信号的辐射等因素都可能是这2种疾病的潜在关联因素。基于分子机制的考虑,慢性炎症反应和氧化应激反应也可能对这种相关性产生影响,因为,这2种生物反应过程均在心血管疾病和癌症机制中发挥重要作用。

但是,尽管有上述人口研究和共同的风险因素/生物机制的证据,也不能完全排除其他疾病因素对心血管疾病与癌症相关性的影响。此外,由于心力衰竭患者的临床评估本身更为频繁,因此,其癌症的早期检出率可能比普通人群更高,但这并不能说明此类患者的癌症风险较高。

JACC:依度沙班在亚洲房颤患者中的安全和有效性研究

目前,对于亚洲房颤患者,依度沙班在预防出血和卒中风险方面是否优于华法林尚不清楚。本研究的目的旨在评估依度沙班和华法林在韩国房颤患者中的安全性和有效性。通过韩国国家健康数据库,本研究纳入了4200名服用依度沙班和31565名服用华法林的房颤患者,并分析其缺血性卒中、脑出血(ICH)、胃肠出血、主要出血事件和全因死亡风险。通过倾向性评分匹配,本研究最终以1:3比较了4061名服用依度沙班和12183名

JACC:Takotsubo综合征的远期预后研究

目前,由于临床资料的局限性,关于Takotsubo综合征(TTS)的远期预后尚不清楚。本研究的目的旨在比较和评估TTS和急性冠脉综合征(ACS)患者的预后,并基于不同的触发因素评估TTS的短期和长期预后情况。本研究纳入了1613名TTS患者,并将其与年龄和性别相匹配的ACS患者进行预后情况的比较。在1613名TTS患者中,有485名(30%)患者的触发因素为情感因素,630名(39%)患者的触发因

JACC:二尖瓣反流患者中的左室纤维化情况

近期有研究报道原发性二尖瓣反流(MR)患者的左室纤维化主要是由二尖瓣脱垂(MVP)导致。本研究的目的旨在通过心血管磁共振(CMR)评估MR伴有MVP或者不伴有MVP患者的左室纤维化的发生率、临床特征和预后。本研究对一个大型MR队列中的患者分成了MVP组和非MVP组,主要终点事件是心律失常事件(心源性死亡、心脏骤停和持续性或诱导性室性心律失常)。最终,本研究共纳入356名原发性MR患者,其中177名

JAMA Intern Med:心血管疾病风险汇总队列预测方程仍需更新

2018年7月23日在线发表于《JAMA Internal Medicine》杂志上的一项研究表明,如果未纳入动脉硬化性心血管疾病(ASCVD)事件监测信息,汇总队列方程(PCE)预测的心血管疾病风险的作用较低,而增加来自医疗保险和医疗补助服务中心(CMS)的监测数据则可以使其更加准确。
