Circulation:房颤的遗传易感性、临床危险因素负担和终生风险分析!

2017-11-13 xing.T MedSci原创

在这项社区为基础的队列中,房颤的终生风险为37%。多基因房颤风险的估计是可行的,加上临床危险因素负担可以解释长期房颤风险的严重梯度。

考虑遗传易感性和临床危险因素负担的房颤发生的长期几率尚不清楚。近日,心血管领域权威杂志Circulation上针对这一问题发表了一篇研究文章。

研究人员估计了来自于社区为基础的Framingham心脏研究的个体房颤的终生风险,利用大约1000个房颤相关的单核苷酸多态性来推断房颤的多基因风险。研究人员采用由身高、体重、收缩压和舒张压、吸烟状况、抗高血压药物、糖尿病心肌梗死病史及心衰史组成的经验证的房颤发生风险评分来计算每一个人的临床危险因素负担。研究人员估计了房颤在多基因和临床危险因素方面的终生风险。

在4606名无房颤的年龄为55岁的受试者中,580人发生房颤(平均随访9.4年;第25-75百分位数为4.4-14.3年)。55岁后房颤的终生风险为37.1%,受多基因和临床危险因素负担的影响较大。在无房颤的年龄为55岁的受试者中,多基因和临床风险为较低三分位数组的受试者发生房颤的终生风险为22.3%(95%可信区间[CI]为15.4%-29.1%),而多基因和临床风险为较高三分位数组的受试者风险为48.2%(95%CI为41.3%-55.1%)。将遗传易感性进行调整后,较低的临床危险因素负担与较晚的房颤发病有关(P<0.001)。

在这项社区为基础的队列中,房颤的终生风险为37%。多基因房颤风险的估计是可行的,加上临床危险因素负担可以解释长期房颤风险的严重梯度。
