两项重要的以人群为基础的流行病学研究评估了无症状宫颈杂音的发生和影响。Fragrance研究跟踪了171名（66名男性和105名女性）新发现的无症状杂音长达8年。2杂音的患病率随年龄的增加而增加（44 ~ 54奥尔兹为3.5%，65 ~ 79奥尔兹为7.0%），并随高血压和糖尿病的存在而增加。杂音患者的卒中发生率是预期发生率的两倍多，但一半是非缺血性卒中，不适合杂音侧，或由于心源性栓塞（表1）。
Two important population-based, epidemiological studies assess the occurrence and implications of asymptomatic cervical bruits. The Framingham Study followed 171 people (66 men and 105 women) with newly detected, asymptomatic bruits for up to eight years. 2 The prevalence of bruits increased both with age (3.5% in 44 to 54 year olds, 7.0% in 65 to 79 year olds) and with the presence of hypertension and diabetes mellitus. The stroke rate in the patients with bruits was more than twice the expected incidence, but half were either nonischemic strokes, not appropriate to the side of bruit, or due to cardiogenic embolism (Table 1).
