摘要
目的探讨不同年龄段急性ST段抬高型心肌梗死(STEMI)患者经皮冠状动脉介入治疗(PCI)后心肺运动试验(CPET)的临床特点。方法选取自2016年9月至2018年9月北部战区总医院心血管内科收治的PCI后行CPET检查的106例STEMI患者为研究对象。根据年龄将其分为A组(年龄<65岁,n=92)与B组(年龄≥65岁,n=14)。记录并比较两组患者的临床资料、CPET执行方案及终止原因、CPET检测结果。结果两组患者临床资料比较,差异均无统计学意义(P>0.05)。两组患者各CPET终止原因比较,差异均无统计学意义(P>0.05)。A组患者每分钟递增功率、运动总时间均大于B组,差异均有统计学意义(P<0.05)。B组患者静息心率、无氧阈心率均高于A组,峰值摄氧量、峰值公斤摄氧量、无氧阈每搏氧耗量、峰值每搏氧耗量、代谢当量、峰值负荷用力肺活量、第1秒用力呼气量、第1秒用力呼吸容积占用力肺活量的比值、最大通气量均低于A组,差异均有统计学意义(P<0.05)。结论不同年龄STEMI患者的CPET指标存在一定差异,年龄≥65岁的老年STEMI患者可能具有较差的运动耐力以及呼吸储备。
Objective To analyze cardiopulmonary exercise testing(CPET)data of different age subgroups of patients with acute ST-segment elevation myocardial infarction(STEMI)after percutaneous coronary intervention(PCI).Methods A total of 106 STEMI patients who received CPET after PCI in the cardiovascular department of General Hospital of Northern Theater Command from September 2016 to September 2018 were included.According to their age,they were divided into group A(age<65 years,n=92)and group B(age≥65 years,n=14).To compare the differences of baseline data,CPET scheme and examination data of patients under different age grouping standards.Results There was no statistical significance in the clinical data of 2 groups(P>0.05).There was no significant difference in the termination reasons of CPET between 2 groups(P>0.05).The increasing power per minute and total exercise time in group A were greater than those in group B,with statistical significance(P<0.05).The resting heart rate and anaerobic threshold heart rate in group B were higher than those in group A.Peak oxygen uptake,peak oxygen uptake in kg and anaerobic threshold oxygen pulse,peak oxygen pulse,metabolic equivalent,peak forced vital capacity,forced expiratory volume in the first second,forced expiratory volume in 1 second/forced vital capacity,maximum ventilatory volume are lower than group A,the differences were statistically significant(P<0.05).Conclusion There are some differences in CPET index in patients with different ages of STEMI.Elderly patients with STEMI aged≥65 years may have poor exercise endurance and respiratory reserve.
