老年急性冠脉综合征直接冠状动脉支架植入远期疗效观察

Observation on long-term outcomes in old patients with acute coronary syndromes underwent direct coronary artery stenting

目的探讨老年急性冠脉综合征患者直接冠状动脉支架植入后远期临床疗效。方法选择老年急性冠脉综合征患者24例,非经球囊预扩张直接植入冠状动脉支架,随访观察患者远期临床疗效。结果经选择性冠状动脉造影检查,选择符合入选标准的34处病变,成功直接植入冠状动脉支架32个,无急性期并发症。进行(26.29±14.72)个月的随访,术后胸痛发生率8.3%,支架植入后再狭窄率12.5%。结论直接冠状动脉支架植入治疗老年急性冠脉综合征切实可行,并且具有较好的远期临床疗效。

Objective To study on the long-term clinical outcomes of the old patients with acute coronary syndrome after direct coronary artery stenting. Methods Twenty-four old patients were selected after coronary artery angiography. These patients were all followed-up to observe the long-term clinical outcomes. Results Thirty-two stents were successfully implanted by direct coronary artery sten ting in 34 lesions according with seleted standard in 24 patients. No acute complications happened. The time followed-up was 26.29 ±14. 72 months. The incidence of post-operative chest pain was 8.3% ,and the incidence of re-stenosis was 12.5% after stenting. Conclusions Direct coronary artery stenting is practicable and has better long-term outcome.
