To determine whether fibrinogen levels predict independently progression of coronary artery calcification (CAC) in adults with type 1 diabetes.
Data from a prospective cohort--the Coronary Artery Calcification in Type 1 Diabetes Study--were evaluated. Fibrinogen levels at baseline were separated into quartiles. CAC was measured twice and averaged at baseline and at follow-up 2.4+/-0.4 years later. CAC progressors were defined as participants whose square-root transformed CAC volume increased by >or=2.5 mm3 or development of clinical coronary artery disease during the follow-up period.
Fibrinogen levels were higher in progressors than in non-progressors (276+/-61 mg/dl versus 259+/-61 mg/dl, p=0.0003). CAC progression, adjusted for known cardiovascular risk factors, increased in the highest quartile.
Higher fibrinogen levels predict CAC progression in type 1 diabetes subjects, independent of standard cardiovascular risk factors.
确定纤维蛋白原水平是否可独立预测 1 型糖尿病患者冠状动脉钙化(CAC)的进展。
对前瞻性队列研究——1 型糖尿病的冠状动脉钙化研究的数据进行评估。将基线时的纤维蛋白原水平分为四等份。在基线和 2.4±0.4 年后的随访时分别测量两次 CAC,并取平均值。CAC 进展者定义为在随访期间其 CAC 体积的平方根增加≥2.5mm3 或出现临床冠心病的患者。
与非进展者相比,进展者的纤维蛋白原水平更高(276±61mg/dl 比 259±61mg/dl,p=0.0003)。在调整了已知心血管危险因素后,最高四分位数的 CAC 进展增加。
较高的纤维蛋白原水平可预测 1 型糖尿病患者的 CAC 进展,独立于标准心血管危险因素。
