为了解心房颤动（Ａｆ）并发血栓栓塞的危险因素，对连续收住院的４３８例Ａｆ患者进行了分析。其中１４９例并发血栓栓塞（３４．０％）。年龄≥６０岁者４０．０％并发栓塞，＜６０岁者则为１９．５％（Ｐ＜０．００５）；持续性Ａｆ者４３．３％并发栓塞，阵发性Ａｆ者则为１６．９％（Ｐ＜０．００５）；ｆ波为粗波者７３．Ｏ％并发栓塞，细波者则为１９．０％（Ｐ＜０．００５）。栓塞组平均左房内径（ＬＡＤ）和血浆纤维蛋白原浓度分别为：４．４４±０．５２ｃｍ和４．３８±０．７８ｇ／Ｌ；无栓塞组则分别为３．５５±０．４４ｃｍ和３．６２±０．５６ｇ／Ｌ（Ｐ＜０．０１）．Ａｆ并发栓塞组的基础心脏病有冠心病、风湿性心脏病、高血压性心脏病、扩张型心肌病等。结果表明，年龄增大、器质性心脏病、持续性Ａｆ、ｆ波振幅与ＬＡＤ增大和血浆纤维蛋白原增加等６项指标是Ａｆ病人发生血栓栓塞的危险因素。
To understand the risk factors for atrial fibrillation (Af) complicated with thromboembolism, 438 consecutive Af patients admitted to hospital were analyzed. 149 of them complicated thromboembolism (34.0%). Thirty-six percent of patients aged ≥60 years had thrombo-embolization compared with 19.5% of patients <60 years of age (P <0.005), 43.3% of those with persistent embolism and 16 of those with paroxysmal Af. 9% (P <0.005); f wave is coarse wave 73. O% embolism, while the fine wave was 19.0% (P <0.005). The average left atrium diameter (LAD) and plasma fibrinogen concentration in the embolization group were 4.44 ± 0.52 cm and 4.38 ± 0.78 g / L, respectively, while those in the non-embolic group were 3.55 ± 0.44 cm and 3.62 ± 0.56g / L (P <0.01). Af concurrent embolism group of heart disease with coronary heart disease, rheumatic heart disease, hypertensive heart disease, dilated cardiomyopathy and so on. The results showed that age, organic heart disease, persistent Af, f wave amplitude and LAD increased and plasma fibrinogen and other six indicators of the risk of thrombosis in patients with Af risk factors.
