冠心病介入术后早期平板运动试验探讨

Study of early treadmill exercise test in patients with coronary artery disease after percutaneous coronary intervention

目的:研究冠心病患者介入治疗后早期平板运动试验的意义。方法:采用修订Bruce方案对45例冠心病患者在介入术后7～30d进行平板运动测试。结果:45例患者中,9例(20%)出现阳性。平均运动时间为(406.5±135.7)秒,平均代谢当量为(9.4±2.6)METs,进一步分级显示:≤4METs者0例,≤7METs的19例,≤10METs的4例,≤13METs的17例,≤16METs的5例。无1例出现心血管事件。结论:冠心病患者介入术后进行早期活动平板运动测试是安全、可行的。可作为康复评定和预后的指标。

Objective： To study the significance of early treadmill exercise test in patients with coronary artery disease （CAD） after percutaneous coronary intervention （PCI）. Methods： Using modified Bruce scheme, 45 CAD patients were tested after PCI in 7-30 days. Results： Among the 45 patients, 9 were indicated positive results （20%） . The mean exercise test time was （406.5±135.7） s, and mean metabolic equal was （9.4±2.6） METs. Among the patients, nobody was less than 4 METs, 19 cases were ≤7METs. four cases were ≤10METs, 17 cases were 13METs, five cases were ≤16METs. Cardiovascular events occurred in no patient. Conclusion： Early treadmill exercise test in patients with coronary artery disease after PC1 is safe and feasible. It can act as a index for prognostic and cardiac rehabilitation.
