摘要
目的 探讨从临床角度筛选钙化易患病例以确定血管内超声适应症的可行性。方法 用血管内超声观察了８８例经皮冠脉球囊成形术患者狭窄部位钙化的发生率、范围及分布类型， 并分析其与年龄、性别及冠心病危险因子之间的关系。结果 ①钙化发生率为３８．６％ ，其中浅表型钙化占５２．９％ ， 弧度＞ １８０°的广泛钙化仅为４．５％ ； ②年龄是影响钙化的主要因素， ＜ ６０岁组的钙化发生率为１７．４％ ， 而≥６０岁组的钙化发生率及广泛钙化率均显著增高； ③＜ ６０岁组中， 钙化（＋ ）组危险因子积分明显高于钙化（－ ）组， 提示冠心病危险因子对＜ ６０岁病例的钙化形成有较大影响。结论 介入性心导管治疗术前血管内超声检查在≥６０岁和＜ ６０岁却具备两个以上冠心病危险因子的病例更有意义。
Objective To identify a subset of patients with high probability of extensive calcification for further intravascular ultrasound (IVUS) examination. Methods The incidence, extent and distribution of calcification in stenosis site assessed with IVUS and its correlation with age, gender and coronary risk factors were analyzed in 88 patients undergoing balloon angioplasty. Results\ Results\ ①The incidence of calcification in stenosis site was 38.6%, 52.9% of which showed a superficial pattern and only 4.5% had extensive calcification0. ②Age was the most influencing factor of calcification, and the incidence of calcification was remarkarbly higher in patinents≥60 years old than in those <60 years old(61.9% vs 17.4 %, P < 0.001 ). ③Among patients <60 years old, patients with calcification had a higher score of risk factors than those without calcification, suggesting that the risk factors play an important role in calcification in these patients <60 years old . Conclusions This study indicates that pre intervention IVUS examination may be necessary in patients ≥60 years old and in those <60 years old but with more than two risk factors.
